Top 50 Software Development Companies: 2026 Edition

Accenture is a professional services company whose principal executive offices are in Dublin, Ireland. Its custom software work sits inside a much broader offer that also spans strategy consulting, cloud migration, managed operations and industry platforms, which is why it tops any revenue ranking of firms that build software for clients. In the fiscal year ended 31 August 2026 it reported revenues of US$74.18 billion, up from US$69.67 billion a year earlier, and employed approximately 814,000 people. The 10-K records US$4.9 billion invested across 17 strategic acquisitions in fiscal 2026, alongside spending on research and development and training. The firm's size means engagements typically run through large multi-year programmes rather than small product builds.

NTT DATA Group is the IT services subsidiary of the NTT telecommunications group and one of the largest systems integrators in the world. Its business combines custom system development for Japanese government, financial and corporate clients with a large overseas segment. For the fiscal year ended 31 March 2026 (which the company calls FY2025) it reported net sales of ¥5,004.6 billion, up 7.9% year on year, and operating profit of ¥488.2 billion; both figures were company records. New orders received reached ¥6,010.5 billion, a figure that includes its data-centre business. That data-centre activity means not all of the revenue counted here is software engineering, a caveat that applies to several of the largest entries.

Tata Consultancy Services (TCS) is the IT services company of the Tata group and the largest Indian provider of outsourced software development and maintenance. Its model relies on large delivery centres in India serving clients in North America, the United Kingdom and continental Europe, with application development and maintenance as the historic core. For the fiscal year ended March 2026 it reported revenue of ₹2,67,021 crore and a workforce of 584,519 at year end. Coverage of the results noted that full-year revenue fell in constant-currency terms, the first such annual decline in the company's listed history, even as fourth-quarter revenue recovered. The figure used here is the rupee total converted at the 2025 average rate.

Capgemini is a French consulting and technology services group whose results are issued from Paris. Its custom software engineering is delivered through application services, cloud and data practices and the Capgemini Engineering unit, which works on product and embedded software for manufacturers. Revenue for 2025 was €22,465 million, up 1.7% reported and 3.4% at constant exchange rates. Headcount rose by 82,300 to 423,400 at the end of 2025, mainly because of the integration of WNS, the business-process company acquired in the fourth quarter. The company reported €3.8 billion spent on acquisitions in the year, principally WNS, which shifts its mix further toward operations work.

Cognizant Technology Solutions has its worldwide headquarters in Teaneck, New Jersey, and delivers most of its work from India, where 256,900 of its approximately 351,600 employees were based at the end of 2025. Its revenue of US$21.11 billion in 2025 was up from US$19.74 billion in 2024. The company is strongest in healthcare and financial services, where it builds and maintains large application estates, and it has added engineering capability through acquisitions such as Belcan in August 2024 and 3Cloud, which the 2025 10-K records as a subsequent event in January 2026. Voluntary attrition in its tech services workforce fell to 13.9% in 2025 from 15.9% in 2024.

Infosys was incorporated in Pune in 1981 and today has its principal executive offices in Electronics City, Bengaluru. It is the second-largest Indian IT services firm and reports under IFRS in US dollars. Total revenues for fiscal 2026 were US$20,158 million, compared with US$19,277 million in fiscal 2025; 97.1% came from services delivered outside India. At 31 March 2026 it had 328,594 employees, of whom 310,887 were professionals involved in service delivery. Infosys builds and maintains custom applications for financial services, retail, manufacturing and communications clients and also sells Finacle banking software, a product line that sits outside pure services.

HCLTech (HCL Technologies) is an Indian IT services company that combines application development, engineering and R&D services, infrastructure management and a software-products division. Its fiscal 2026 revenue rose 11.18% to ₹1,30,144 crore, and net headcount reached 227,181 after 3,761 net additions during the year. Its engineering and R&D services unit, which writes embedded and product software for technology, automotive and medical-device makers, is one of the largest in the sector. Its HCLSoftware segment means part of the revenue is licences and support rather than custom development. Results for the fourth quarter were announced on 21 April 2026.

CGI was founded in 1976 and describes itself as one of the largest independent IT and business consulting services firms. Headquartered in Montréal, it combines systems integration and custom development with managed IT, business process services and its own intellectual-property solutions, and it is particularly strong with governments in Canada, the United States, the United Kingdom and the Nordics. For fiscal 2026, ended 30 September 2026, CGI reported revenue of C$16.57 billion, up 4.2% (2.2% in constant currency). It had approximately 94,000 consultants and professionals at year end and reported a trailing twelve-month book-to-bill ratio of 105.6%. The results were released in November 2026.

Wipro was incorporated on 29 December 1945 as Western India Vegetable Products Limited and is now an IT services company headquartered on Sarjapur Road, Bengaluru. Its fiscal 2026 consolidated revenues were ₹926,240 million, up from ₹890,884 million the previous year. The company reported more than 240,000 employees at 31 March 2026, against more than 230,000 a year earlier. Wipro's custom development work covers application modernisation, cloud migration and AI implementation for banking, consumer, energy and healthcare clients. It files an annual report with the SEC on Form 20-F, which is the source used here.

Sopra Steria Group is a French digital services company listed on Euronext Paris, with its results issued from Paris. It develops and maintains custom systems for governments, banks, defence and aerospace companies, and also sells banking and human-resources software. Full-year 2025 revenue was €5,648.0 million, down 2.2% on both a reported and an organic basis, though organic growth turned positive in the fourth quarter at 1.8%. Headcount stood at 51,275 at the end of 2025, with 8,484 employees in international service centres; the acquisitions of Neocase and Aurexia added 230 people. Rajesh Krishnamurthy is chief executive.

Tech Mahindra is the IT services company of the Mahindra group and has historically been strongest in telecommunications, where it builds and maintains operator systems, alongside manufacturing, banking and healthcare. For fiscal 2026 it reported revenue of US$6,385 million (₹56,815 crore, up 7.2%). Headcount was 147,623 at 31 March 2026, 1,108 lower than a year earlier. Under chief executive Mohit Joshi, the company reported US$3,794 million of deal wins in fiscal 2026, its highest in five years. Its revenue in US dollars sits within 0.01% of Sopra Steria's converted total, so the order of those two entries depends on the exchange-rate rule.

EPAM Systems is a software engineering services company whose predecessor was founded in 1993; it was incorporated in Delaware in 2002 and has its principal executive offices in Newtown, Pennsylvania. Revenue for 2025 was US$5.46 billion, up from US$4.73 billion in 2024, helped by the acquisition of NEORIS, a Latin American and Spanish consultancy with about 4,800 professionals, bought for US$626.3 million. EPAM had approximately 62,850 employees at the end of 2025. An employment agreement with Balazs Fejes, its new chief executive, was filed in September 2025.

LTM, the company formerly known as LTIMindtree, is the IT services subsidiary of the Larsen & Toubro engineering group, providing application development, cloud, data and enterprise-platform services, with banking, insurance and manufacturing as major sectors. For fiscal 2026 it reported revenue of ₹42,307.6 crore, up 11.31%, and a headcount of 87,950 at year end, according to results coverage. Venu Lambu is chief executive and managing director. The revenue figure is taken from a market-news report rather than the company's own release, and is converted from rupees for the ranking.

Alten is a Paris-based engineering and technology consulting group; much of its work is embedded and product software for automotive, aerospace, rail, energy and life-sciences clients, alongside mechanical and electrical engineering. Revenue for 2025 was €4,099.0 million, down 1.1% reported and 4.5% on a like-for-like basis, with France growing 4.3% and international activity falling 3.7%. Headcount was 57,400 at the end of 2025, compared with 57,700 a year earlier. Operating profit fell after a €67.4 million goodwill impairment and a fine from the French Competition Authority, which Alten is appealing; the results also reflect the Worldgrid acquisition. Because not all of Alten's work is software, it sits at the edge of this list's scope.

Reply S.p.A. is an Italian group organised as a network of small, specialised companies, each focused on a technology such as cloud, data, AI, SAP, cybersecurity or digital experience. Its consolidated turnover for 2025 was €2,483.6 million, an 8.0% increase on €2,300.5 million in 2024. The board approved the draft 2025 accounts on 12 March 2026 and referred to recent partnerships with leading large-language-model producers. The structure lets Reply staff projects from boutique units rather than from a single delivery organisation, but it also makes the group harder to compare with firms that publish a single headcount.

Globant was founded in Argentina in 2003 by four entrepreneurs, including chairman and chief executive Martín Migoya, and is now domiciled in Luxembourg with its shares listed on the New York Stock Exchange. It builds digital products, platforms and AI-based services, organised in industry-focused units it calls studios. Revenue for 2025 was US$2.45 billion, against US$2.42 billion in 2024, a slowdown from the double-digit growth of earlier years. At 31 December 2025 Globant had 28,773 employees. Its delivery base is concentrated in Latin America, with additional centres in India, Europe and the United States.

Coforge is an Indian IT services company with offices in Princeton, New Jersey, and Greater Noida. It concentrates on banking, insurance and travel, where it develops and maintains core and digital systems. Revenue for fiscal 2026 grew 29.2% to US$1,870 million (₹16,420.7 crore), the fastest growth among the large Indian entries, and the EBIT margin widened by 370 basis points to 14.4%. Sudhir Singh is chief executive. Headcount figures in the company's release were inconsistent between the operating table and boilerplate, so none is shown here.

Mphasis is a Bengaluru-based IT services company listed on the BSE and NSE. Its work is weighted toward banking, financial services and insurance, where it builds and modernises applications and runs cloud migrations, and it also has a sizeable logistics and transportation practice. Revenue for fiscal 2026 was Rs 15,879.65 crore, up 11.59%, and headcount was 27,020 at the end of the fourth quarter. Chief executive Nitin Rakesh reported new deal wins with a total contract value of US$2.1 billion for the year, and the company announced the acquisition of Theory and Practice.

adesso SE is a German IT services company headquartered at Adessoplatz 1 in Dortmund. It develops custom software and implements industry platforms for insurers, banks, health insurers, public administration and manufacturers, mostly in Germany, Austria and Switzerland. Revenue for 2025 was €1.47 billion, up 14% from €1.29 billion, with all of the growth organic. Full-time-equivalent staff rose 9% to 11,298 at year end. adesso is one of the few mid-sized European software developers to have kept double-digit growth through 2025.

Persistent Systems is a software engineering company with dual bases in Santa Clara, California, and Pune, India, and its shares trade on the NSE and BSE. It began as an outsourced product-development partner for software vendors and has expanded into enterprise digital engineering for banks, healthcare companies and manufacturers.

The company describes itself as having over 27,500 employees in 18 countries.

Hexaware Technologies is an Indian IT services company that reports on a calendar-year basis and trades on the National Stock Exchange of India. It provides application development and maintenance, cloud and data services and business process work, with an emphasis on automation. Revenue for 2025 was US$1,537.4 million, up 7.6% (₹13,430.4 crore, up 12.2%), and headcount was 33,844 at 31 December 2025. The company closed two capability acquisitions during the year and was named a Visionary in Gartner's 2026 Magic Quadrant for Custom Software Development Services. Srikrishna is chief executive.

L&T Technology Services (LTTS) is the engineering research and development services company of the Larsen & Toubro group. It writes embedded and product software and provides digital engineering for transportation, industrial products, medical devices, telecom and hi-tech clients, as well as plant engineering. For fiscal 2026 it reported revenue of ₹1,09,959 million, equivalent to US$1,233 million, and a workforce of 23,830 employees. Like KPIT and Tata Elxsi, LTTS is included because software is now the main component of the engineering work it sells, though not all of its revenue is software development.

Nagarro SE is a German digital engineering company with large delivery teams outside Germany. It builds custom software, cloud platforms and data and AI solutions for clients in sectors ranging from automotive to financial services. Audited revenue for 2025 was €999.3 million, up from €972.0 million in 2024, and the company reported 18,003 professionals at 31 December 2025. The audited annual report was published on 29 April 2026 and reaffirmed the preliminary figures. Its revenue places it just above Endava and GFT, the other European mid-sized engineering firms on the list, and it is one of the few in that group to report growth in constant currency in 2025.

Endava plc is a technology services company headquartered at 125 Old Broad Street, London, and listed on the New York Stock Exchange. Its last audited fiscal year, ended 30 June 2025, produced revenue of £772.3 million with an average of 11,614 employees. In September 2026 the board placed the chief financial officer on leave pending an audit-committee investigation, and on 28 October 2026 Endava said it would restate its fiscal 2026 results and that founder and chief executive John Cotterell would retire. Fiscal 2026 accounts were not available when this list was compiled.

GFT Technologies SE is a Stuttgart-based IT services company specialising in banking and insurance. It builds and modernises core banking, payments and insurance systems and named Brazil, Colombia and the United States among its fastest-growing markets in 2025. Preliminary revenue for 2025 was €888 million, slightly above its €885 million forecast, and staff numbered 11,772 full-time equivalents at 31 December 2025. Group net income fell 29%. GFT reported that its Wynxx agentic-AI platform was in use at 92 clients in eight countries, much of it based on Anthropic Claude, OpenAI and Gemini models.

KPIT Technologies is an Indian software company devoted almost entirely to the automotive and mobility industries, writing embedded, autonomous-driving, powertrain and vehicle-diagnostics software for car makers and tier-one suppliers. Revenue for fiscal 2026 was US$724.8 million, up 4.8%. KPIT is one of the most specialised entries on this list: its custom software is tightly coupled to vehicle platforms, and it competes with in-house software units created by carmakers rather than with general IT outsourcers. Because its revenue is tied to vehicle development cycles, its results tend to move with carmakers' research budgets rather than with general IT spending.

Aubay is a French digital services company based in Boulogne-Billancourt. It provides software development, testing, IT consulting and project management, with banking and insurance accounting for most of its revenue, with operations across several European countries. The company states revenue of €601.6 million for 2025 and a team of 9,000 consultants. Its model relies on consultants placed on client projects rather than offshore delivery centres, which distinguishes it from the Indian and Eastern European entries. It is the smallest of the four French entries, alongside the far larger Capgemini, Sopra Steria and Alten.

Zensar Technologies is an Indian IT services company whose results are issued from Pune. It provides application development, digital engineering, cloud and data services, with clients concentrated in hi-tech, manufacturing, consumer and financial services in the United States and Europe. Revenue for fiscal 2026 was US$643.7 million, up 3.1% in reported currency. The results were published on 24 April 2026. Zensar is smaller than the Indian tier-one firms and competes on account focus and senior attention rather than scale.

Knowit AB is a Swedish IT consultancy operating in Sweden, Norway, Finland and Denmark. Its Solutions business area, which builds and maintains custom systems, is the largest of its units. Net sales fell 9.6% to SEK 5,798.0 million in 2025, and the company recorded a SEK 399 million goodwill impairment, producing a loss after tax of SEK 282.1 million. Headcount fell to 3,714 at the end of 2025 from 3,860 a year earlier, after the disposal of Knowit Consulting Services A/S and the acquisition of Insicon AB.

Kainos Group plc is a UK-headquartered IT provider organised in three divisions: Digital Services, Workday Services and Workday Products.

Revenue from Brazilian operations grew 30.8% in local currency, while US revenue rose 9.2%. Headcount increased 15.7% to 7,993 at 31 December 2025.

Tata Elxsi is a Tata group company providing design and technology services, chiefly embedded software for vehicles, software and platforms for broadcasters and media companies, and engineering for medical devices. Its results for fiscal 2026, released from Bangalore on 21 April 2026, showed revenue of Rs 3,757.4 crore. Manoj Raghavan is chief executive and managing director. Like KPIT and LTTS, Tata Elxsi is an engineering-services specialist rather than a general IT outsourcer, and its revenue depends on a small number of large automotive and media clients.

Grid Dynamics Holdings was founded in 2006 and is headquartered in San Ramon, California, with offices across the Americas, Europe and India. It provides AI, data and analytics, platform and cloud engineering and digital-commerce services to retailers, technology companies, financial firms and manufacturers. Revenue for 2025 was US$411.8 million, up 17.5% from US$350.6 million. The 10-K notes that India has become one of its top two countries by headcount, a shift from its historic base in Eastern Europe. Grid Dynamics is listed on Nasdaq.

Happiest Minds Technologies is a Bengaluru-based IT services company focused on digital engineering, product development, infrastructure and security services. Its clients include education-technology, healthcare, banking and industrial firms, mainly in the United States, the United Kingdom and India. Revenue for fiscal 2026 was ₹2,315 crore, up 12.3%, and it had 6,497 people at 31 March 2026. The results were published on 28 May 2026. It is the smallest of the revenue-ranked entries. Its growth rate in fiscal 2026 was higher than that of most larger Indian peers on this list.

Softtek is a Mexican IT services company and one of the largest Latin American providers of outsourced software development, offering clients in North America development and application-maintenance teams in nearby time zones. Softtek's website describes the company as backed by 16,000 global experts. It does not publish audited revenue, so it is ranked here by headcount. Its services range from application development and testing to AI and cloud engineering. Within the headcount-ranked group it is the largest entry, though the figure is a rounded website statement rather than a dated filing.

Birlasoft is part of the CKA Birla Group and is listed on the BSE and NSE. It focuses on enterprise applications such as Oracle, SAP and Infor, together with digital engineering, cloud and data services for manufacturing, life-sciences, energy and financial clients. Its fiscal 2026 results release, dated 6 May 2026, reported fourth-quarter revenue of ₹13,486 million and described the company as having over 11,000 professionals. Because the full-year total was not stated in the document reviewed, Birlasoft is placed in the headcount-ranked group. Angan Guha is chief executive.

Thoughtworks was founded in Chicago in 1993 and is known for its influence on agile and continuous-delivery practice, including its widely read Technology Radar. It builds custom software, modernises legacy platforms and advises on engineering practices, with offices in 22 countries. The company does not currently publish revenue. Its website cites more than 10,000 Thoughtworkers. Its consulting style, which pairs delivery teams with advice on engineering practice, distinguishes it from offshore-centred providers of similar size. The headcount shown is the rounded figure on its own site.

Netcompany Group is a Danish IT services company that builds large custom systems, chiefly for public authorities. In 2025 it merged SDC, a Nordic banking-technology provider, into a new Netcompany Banking Services unit, which added roughly 13 percentage points of reported growth; organic revenue rose 7.7% to DKK 7,044.1 million. The average workforce increased to 8,929 full-time equivalents. Netcompany appears in the headcount group because its reported (as opposed to organic) revenue total could not be confirmed from a primary document during this review.

DataArt was founded in New York in 1997 with a global delivery model from the start. It provides custom software development, data engineering, AI and cloud services, and is known in financial services, travel and hospitality, media and healthcare. The company lists more than 6,000 experts across over 40 locations in more than 20 countries. DataArt is privately held and does not publish revenue. The headcount figure is a rounded statement from its company page rather than a dated filing, so it is used here only to order the private firms.

Xebia began in the Netherlands in 2001 and moved its global headquarters to Atlanta, Georgia, in 2023. It has grown through acquisitions of specialist consultancies into a group offering software development, cloud and DevOps, data and AI, and agile training. The company states that its team includes over 4,500 experts. Xebia is privately held and does not publish revenue. Its training academy and consulting heritage give it a stronger advisory component than most offshore-centred software developers.

Innowise is a custom software development company. It offers web and mobile application development, enterprise software, data and AI engineering, and dedicated teams, and says it has been working on digital solutions since 2007. The company's website cites 3.5 thousand IT professionals. It does not publish financial statements, and its client base is weighted toward mid-sized companies in Europe and North America. Its position is based on the rounded headcount shown on its homepage, which is not dated, so comparisons with neighbouring entries are approximate. The company does not disclose which office serves as its headquarters on that page.

Itransition is a privately held software development company founded in 1998. It builds custom enterprise software, e-commerce and CRM systems and provides application management and data and AI services. The company's website lists more than 3,000 engineers. Itransition does not publish revenue. Its headcount is a rounded, undated figure from its homepage, which places it level with Vention in this ranking; the two are listed in alphabetical order. The homepage does not name a headquarters city, so the country column shows it as not stated.

Vention is a software engineering company whose website lists an office at 575 Lexington Avenue in New York and more than 3,000 engineers across over 20 offices. It supplies dedicated development teams and full project delivery to venture-backed start-ups and growth companies as well as established enterprises. Vention is privately held and does not publish revenue or a dated headcount figure, so its position relies on the figure displayed on its site. Its figure ties with Itransition's, and the two appear in alphabetical order.

N-iX is a software engineering company that lists Valletta, Malta, as its headquarters and has its largest engineering presence in Ukraine and other European countries. It provides AI-augmented software development, cloud, data and analytics, cybersecurity and industry-specific software. Its website states 2,400+ engineers across ten countries and more than 90 enterprise clients, and cites ISO 27001 and ISO 9001:2015 certification. N-iX is privately held and does not publish revenue. Like other firms in this part of the ranking, its position rests on a rounded headcount figure rather than revenue.

10Pearls is a privately held digital product engineering company whose offices include Washington DC, Chicago, London, Medellín, Lima, Karachi, Lahore and Islamabad. It designs and builds web and mobile products, data and AI solutions and cloud platforms, often for venture-backed companies and mid-sized enterprises. The company's website cites a team of 1,400+ people. It does not publish revenue, and its delivery model combines Pakistan-based engineering with nearshore teams in Latin America. The headquarters city is not identified on the homepage reviewed, so the country column shows it as not stated.

Mindera was founded in 2014 and grew from Portugal into a group with offices in ten countries. It builds digital products, mobile applications and cloud platforms. The company's website lists more than 1,344 people. Mindera is privately held and does not publish revenue. Its delivery model relies on small cross-functional teams placed with clients for long-running product work. The headcount shown is the figure on its homepage, which is the only size measure the company publishes, and the homepage does not identify a headquarters.

ScienceSoft is a privately held IT consulting and software development company that says it has been operating since 1989, with a listed address in McKinney, Texas. It develops custom software, implements enterprise systems and provides data analytics, AI, cybersecurity and testing services. Its website cites 750+ consultants, engineers, architects and AI specialists. ScienceSoft does not publish revenue. Its stated operating history is the longest among the privately held firms on the list, although its published headcount is one of the smallest.

STX Next is a Polish software development company headquartered in Poznań. It is best known as a large specialist Python house and builds web platforms, data engineering pipelines and AI applications for clients in Europe and North America. Its website shows 450+ specialists and 21 years in the market. STX Next does not publish revenue. Its size places it toward the end of the list, alongside other Polish software houses such as Netguru, which compete with larger firms on specialist depth rather than capacity.

Netguru S.A. is a Polish digital product consultancy headquartered in Poznań. Since 2008 it has designed and built web and mobile products for start-ups and enterprises, and it now offers AI, data and product-strategy services alongside development. Its website lists 400+ people on board. Netguru does not publish revenue on its site. It is one of two Poznań firms on the list, alongside STX Next, and among the smallest entries; both rely on rounded headcounts published on their websites.

Leobit is a software development company that lists its US headquarters in Austin, Texas, and development centres in Lviv, Tallinn and Kraków, with an office in London. It specialises in .NET, web and mobile development, legacy modernisation and AI integration for small and mid-sized companies and software vendors.
