Mantle

Overview

Mantle is a cap table product operated by Ten Key Labs Incorporated, doing business as Mantle; its site copyright runs from 2022 to 2026. Its main differentiator is the pricing model: every plan, including the free Starter tier, includes unlimited stakeholders with no per-user fees, which removes the overage charges that most rivals apply as a company hires^[12].

Starter offers self-serve spreadsheet import, SAFE e-signing, round modelling and limited AI tooling. Essentials adds concierge onboarding and migration, a one-time cap table clean-up, preferred shares, board consents, HRIS sync and email support. Growth adds an annual 409A valuation, priority support and access to Mantle’s SOC 2 Type 2 report, and Growth+ adds ASC 718, Form 3921, QSBS, Rule 701 and 83(b) tracking^[12].

Mantle states that most migrations from Carta or Pulley take three to five business days and that cap tables, reports and documents can be exported in bulk. The company does not publish a customer count, headquarters or founding year on its pricing page, and compliance reporting is reserved for its custom tier^[12].
