Best Sales Intelligence Tools in 2026

ZoomInfo is a go-to-market data platform headquartered in Vancouver, Washington. It was founded in 2007 as DiscoverOrg by Henry Schuck, who remains chief executive and chairman; DiscoverOrg acquired ZoomInfo in 2019 and took its name, and the Nasdaq ticker changed from ZI to GTM in 2025.

The company states that its database holds more than 500 million contacts and 100 million companies, including 135 million verified phone numbers and 200 million verified business emails, with 34 million companies and 200 million professionals outside North America. Revenue for 2025 was US$1,249.5 million under US GAAP, up 3%; third-quarter 2026 revenue was US$308.8 million, down 3% year on year, and the company ended that quarter with 1,851 customers paying US$100,000 or more in annual contract value.

Sales packages run from Professional, with contact and company profiles, search, export and CRM integrations, to Copilot Advanced and Copilot Enterprise, which add account prioritisation, buyer intent, website-visitor data and AI-generated account summaries. Separate marketing packages bundle intent topics and audience targeting. Prices are not published. The documented limitations are cost and contract structure: richer credit types such as technographics and org charts cost more than basic credits, and recent filings show flat-to-declining revenue and net revenue retention of 88%, indicating customers trimming spend.

Sales Navigator is LinkedIn's paid prospecting product, sold through LinkedIn's Sales Solutions business. LinkedIn is owned by Microsoft, whose fiscal 2026 annual report lists Sales Solutions among LinkedIn's monetised offerings and reports that LinkedIn revenue increased 11% in the year. LinkedIn describes a community of more than 1.4 billion members.

Unlike the database vendors in this list, Sales Navigator does not sell email addresses or phone numbers. Its data is the LinkedIn profile itself, kept current by members, and its tools are built around search and relationships: more than 50 advanced search filters, Account IQ and Lead IQ summaries, buyer-intent signals, the Relationship Explorer and Relationship Map, TeamLink for finding colleagues' connections, alerts on job changes and InMail messaging.

Plans are Core for individual sellers, Advanced for sales teams and Advanced Plus for teams that want CRM integration, including creating leads and contacts in the CRM. The pricing page lists 50 InMail credits a month. The main limitations follow from the model: contact details must come from another tool, data cannot be exported in bulk, and CRM integration is reserved for the top, quote-based tier. Many teams pair Sales Navigator with a contact-data extension such as Lusha or Kaspr, both of which advertise Sales Navigator support.

Apollo.io was founded in 2015 by Tim Zheng, its chief executive, and Ray Li, its chief technology officer. Its investors include Bain, Sequoia, Tribe, Nexus, NewView and Y Combinator. The company says it has 40,000 paying customers and that 1 million sales professionals use it to enrich and analyse prospect data.

The product combines a database of 240 million contacts and 30 million companies with sales-engagement features normally sold separately: email sequencing, a dialler with call recording on higher plans, CRM integrations and AI features. This combination makes it the main published-price alternative to ZoomInfo for small and mid-sized teams.

Apollo.io offers a free plan that it says stays free with no time limit; free accounts can connect Gmail mailboxes only. The Basic plan targets individual sellers doing regular outbound, Professional adds higher credit limits, AI features, call recording and advanced CRM integrations, and Custom covers SSO, advanced security, custom volumes and API access. Credits are pooled across a team, granted at the start of each billing cycle and expire at the end of it without rolling over; extra credits can be bought and renew each cycle until removed. Without a higher-tier limit, users can export up to 10,000 leads in one action. Limitations include the expiring credits, API access restricted to Custom plans, and phone coverage that buyers in Europe often supplement with a specialist provider.

Cognism (Cognism Ltd) is a sales intelligence company founded in 2015 and led by chief executive Dominic Allon. In 2022 it acquired the French contact-finder Kaspr and raised a Series C round. It says more than 4,000 companies use its data.

Cognism positions itself on European data and on compliance. Its pricing page describes "European B2B data for global enterprise growth" and phone-verified mobile numbers, which it says improve connect rates. Its security page states dual ISO 27001 and ISO 27701 certification from a UKAS-accredited body, SOC 2 Type II for security and availability, GDPR and CCPA alignment, and automatic suppression against global Do-Not-Call and TPS lists.

There are two prospecting plans, each including five seats. Standard covers contact and company data, firmographic, technographic and signal filters, AI company research, CSV enrichment and API and MCP access. Pro adds higher-quality mobile data, on-demand mobile verification and intent data powered by Bombora, from which administrators choose up to 12 topics out of more than 11,000. A CRM Enrichment product maintains CRM records and re-spends credits only when key details such as a job change alter. Viewing a previously revealed contact is free. The limitations are that all pricing is quote-based, the five-seat packaging is less suited to single users, and intent data requires the Pro plan.

Lusha was founded in 2016 by Assaf Eisenstein, its president, and Yoni Tserruya, its chief executive. The company says it is used by more than 280,000 revenue teams and cites a dataset of 515 million business contacts and 29 million company profiles.

Lusha is best known for its browser extension, which reveals emails and phone numbers while a user browses LinkedIn or a company website, and for a web workspace for list building. A single credit balance works across the workspace, the extension, the API and an MCP connection for AI tools. A verified email costs one credit and a phone number five.

Pricing is among the most transparent in the category. Plans run from a free tier with 40 credits a month through Starter, Professional (marketed as Pro) and Premium to a custom Scale plan. On monthly billing, unused credits roll over up to twice the plan limit while the subscription continues; annual plans issue credits up front and reset at the end of the year. Teams of more than five users are directed to sales, and per-user credit limits are available only on Scale.

On compliance, Lusha states that it is independently audited under ISO 27701, ISO 27001 and SOC 2 Type II, that it complies with GDPR and CCPA, and that it is validated by TrustArc and ePrivacyseal. Its limitations are the cost of phone reveals at five credits each and the requirement to negotiate once a team grows beyond five users.

D&B Hoovers is the sales and marketing intelligence product of Dun & Bradstreet, the business-information company best known for its D-U-N-S identifiers and commercial credit data. Dun & Bradstreet has been privately held since 26 August 2025, when Clearlake Capital completed its acquisition; stockholders received US$9.15 a share in cash and the shares were delisted from the New York Stock Exchange.

Dun & Bradstreet describes Hoovers as a tool to identify and prioritise opportunities using its data, buying signals and AI-generated insights. The product page lists company and contact intelligence for finding accounts and buying groups; buying signals, trigger events, website engagement and company news; account prioritisation based on fit and business change; AI workflows for outreach; and an MCP connection that brings Hoovers data into AI tools and agent workflows. A Salesforce integration is referenced in a customer testimonial.

Hoovers' distinguishing feature is its parent's data heritage: organisations that already use Dun & Bradstreet for supplier risk or credit decisions can use the same company records for prospecting, which simplifies matching across finance and sales systems. The product page does not publish database counts or prices; it offers a free trial and directs buyers to a sales line. The limitations are the lack of published pricing, less emphasis on self-serve contact reveals than the extension-based tools, and the uncertainty that typically accompanies a change of ownership to private equity.

6sense is a San Francisco-based company founded in 2013 that describes AI as its foundation; its investors include Insight Partners. It is primarily an account-based marketing and revenue platform, but sells a dedicated Sales Intelligence package alongside its marketing products.

The pricing page offers three starting points rather than tiers. Revenue Marketing covers advertising, segments, Intelligent Workflows and the RevvyAI assistant. Sales Intelligence provides company and contact data, recommended contacts, AI insights and RevvyAI for sellers. 6sense Intelligence packages the same data for data and analytics teams. Every option includes governance controls, security and compliance features, an onboarding sandbox, APIs and native integrations, an MCP server and alerts. Add-ons include AI email agents, a Bombora topic pack, extra credits, predictive models, advanced security and data packs.

Buyers can run the full platform, consume 6sense data inside their existing stack through Salesforce, HubSpot or Snowflake integrations and APIs, or connect it to AI tools through MCP; data packs can be bought without the platform. Seats, credits, records and conversations are priced in volume bands. The main limitations are opacity and complexity: no prices or free plan are published, trials are by arrangement, and the platform's value depends on running coordinated marketing and sales programmes, which smaller teams may not have.

Demandbase was founded in 2006 by Chris Golec to give B2B marketers better intelligence about the companies they target. Its chief executive is Gabe Rogol. The company built its data assets partly through acquisitions: Spiderbook in 2016 for predicting likely buyers, Engagio in 2020, and InsideView and DemandMatrix in 2021, which it describes as creating a one-stop shop for data. It reports more than 1,000 customers.

InsideView was itself a long-standing sales intelligence vendor, and DemandMatrix supplied technographic data, so Demandbase today combines account identification, intent, advertising and company and contact data in one platform. Demandbase does not split its platform into separate marketing and sales products; its flagship Demandbase for Sales & Marketing is priced as a platform fee plus a flat per-user fee, so cost scales with team size. Advertising can be bought as a starting point, and data solutions can be bought on their own to feed B2B data and AI insights into existing systems.

The model suits organisations where marketing and sales share account lists and want one source for both. The limitations are that prices are not published, no free trial is mentioned, and a team that needs only contact details will pay for capabilities it does not use.

Clay began in Brooklyn in 2017. Its about page reports a US$115 million raise at a US$7.1 billion valuation led by Wellington Management, following a US$100 million Series C at a US$3.1 billion valuation; investors include Sequoia, Meritech, CapitalG and First Round. Named customers include OpenAI, ElevenLabs, Mistral AI and Intercom.

Clay is not a single database. It is a spreadsheet-like workspace that queries more than 150 data providers, often in a waterfall that tries one source after another until a field is found, and adds an AI research agent, Claygent, that reads websites to answer custom questions about each account. Growth-marketing and sales-operations teams use it to build highly specific lists that standard filters cannot express, and the company associates its rise with the job title "GTM engineer".

Plans are metered in two units: actions and data credits. The free plan includes unlimited seats and tables, multi-provider waterfalls, Claygent and bring-your-own API keys, but no phone enrichment and a 200-row table limit. Launch adds phone enrichment, job-change signals and email sending; Growth adds CRM auto-sync, HTTP API integrations and web intent signals; Enterprise adds SSO/SAML, SCIM, role-based access and data-warehouse connections. Annual billing saves 10%. Limitations: the pricing page itself shows inconsistent figures between its header and FAQ, credit rollover rules are stated differently in two places, and the product requires more setup skill than a point-and-click contact finder.

UpLead is a self-serve B2B contact database aimed at small and mid-sized teams. Its pricing page states a data accuracy rate of 95% for verified emails, technographic coverage of more than 16,000 technologies and use by more than 4,000 businesses.

The product follows a simple model: one credit unlocks one contact for download or CRM export, including the email and mobile direct dial where available. That contrasts with vendors that charge more for phone numbers than for emails. Users search by firmographic and technographic filters, verify emails in real time, and push records into a CRM or export them.

Plans begin with a seven-day free trial with five credits. Essentials adds CRM integration, and on annual billing company news and alerts. Plus adds data enrichment, email-pattern intelligence, technographics, advanced filters and suppression-list uploads. Professional, sold on annual billing only, adds buyer intent data, the full filter set, full API access, bi-directional CRM sync, competitor intelligence, team management and a dedicated success manager.

The accuracy figure is the vendor's own and is not independently audited. Other limitations are that paid self-serve plans are single-user, intent data and full API access require the unpriced Professional tier, and the page does not state the total size of the database.

LeadIQ is a prospecting tool built around capturing contacts while browsing and pushing them into CRM and sales-engagement systems. Its pricing page lists three plans: Free, Pro and Enterprise.

Pro includes people search for emails and mobile numbers, a Chrome extension for prospecting, exporting and API access, tracking of job changes for past customers and champions, signals drawn from 10-K filings, podcasts and hiring, an AI outbound message writer, and CRM and web-form enrichment. Enterprise adds AI account prospecting, governance controls over prospect data, CSV enrichment, Salesforce duplicate detection, team analytics, custom CRM field mappings, an agent product called Lando and SSO.

The free plan gives one user 50 credits with the same core features as Pro. Pro is credit-based and supports up to five users, and every plan can be tried free for 30 days. Credit costs are explicit: an email costs one credit, a phone number ten, both together eleven and an account enrichment three.

Job-change tracking is LeadIQ's most distinctive feature, since champions who move to a new employer are among the warmest prospects a seller has. The main limitation is the cost of phone data at ten credits per number, the highest ratio among the published plans in this list, and Pro's database search is described as limited access.

Kaspr is a contact-finder centred on a Chrome extension that reveals phone numbers and emails from LinkedIn profiles, including inside Sales Navigator and, on higher plans, LinkedIn Recruiter Lite. Cognism acquired Kaspr in 2022.

Kaspr separates three kinds of credit: B2B email, phone and direct (personal) email. Every paid plan includes unlimited B2B email credits, so the binding limit is usually phone credits. The free plan provides 15 B2B email, 5 phone and 5 direct email credits a month, with lead management and limited CSV enrichment. Starter adds Sales Navigator support, shared team credits and usage reports; Business adds Recruiter Lite support, custom permissions and exportable reports; Enterprise adds unlimited phone credits, intent data, SSO and advanced Salesforce enrichment.

Prices are published per user per month in euros, pounds and US dollars, with discounted figures shown against struck-through list prices. Export limits rise from 100 on the free plan to 12,000 a year on Starter and 30,000 a year on Business.

Kaspr suits individual recruiters and sellers who work mainly on LinkedIn and want a lower entry price than Cognism itself. Limitations: phone credits are capped at 100 or 200 a month on self-serve plans, its add-on credit tables contain apparent errors, and it lacks the list-building depth of a full database product.
