What Capbase does
Capbase is a San Francisco-based digital governance and startup management SaaS platform founded in 2018 that helps early-stage founders incorporate Delaware corporations, manage cap tables, issue equity, raise funds from investors, and handle employment and compliance documentation. The cloud-based product combines Delaware corporation formation, real-time cap table management with automatic updates upon contract signing, SAFE and convertible note issuance, investor CRM, a virtual data room, board setup, and integrations with banking (Mercury, Brex), HR/payroll (Gusto, Deel), and productivity tools (Google Workspace, Slack, GitHub, AWS). Capbase itself operates as a licensed Delaware registered agent, allowing it to file state documents directly. The platform is delivered as a self-serve product-led growth offering, with founders able to sign up and incorporate in under 10 minutes, supported by an SEO-driven content marketing engine covering incorporation, equity, fundraising, and compliance topics.
Capbase monetizes through tiered annual subscriptions: an Early-Stage tier at $999/year covering incorporation, stock issuance, cap table management, and unpriced-round fundraising, and a Growth-Stage tier at $4,999/year for companies pursuing priced rounds and 409a valuations, with onboarding fees available for companies already incorporated. The company serves a long-tail of early-stage startup founders as its primary customer segment, with secondary exposure to existing pre-incorporated companies and, following its October 2025 acquisition by Mainstreet, the broader small business market. The customer base is described as 'hundreds of startup founders,' with no large enterprise anchors and only small reference customers such as Global RCG Inc., Rita Health (Women AI Inc.), and Clutch Wallet.
The company's only disclosed funding round closed in September 2021 with participation from Clocktower Technology Ventures, LAUNCH, and The Syndicate.com; no dollar amount was disclosed, and headcount remained in the 11-50 band. In October 2025, Capbase was acquired by Mainstreet to be combined into a 'first founder and small business operating system' that integrates company formation with payroll, accounting, tax credits, banking, and benefits. The acquisition also established a preferred partnership with Deel for hiring and compliance, alongside existing partner-perk relationships with AWS, Vouch, Bench, HubSpot, and Slack. Co-founders Greg Miaskiewicz (CEO) and Stefan Nagey led the company prior to the transaction.

Capbase competitors and assessment
Company assessmentOthers
- Brex: Brex is a startup-focused spend and banking platform and a Capbase integration partner; it overlaps in serving early-stage founders with embedded financial tooling that could be extended into formation flows.
- Mercury: Mercury is a startup-focused digital bank that integrates with Capbase via Plaid; it is a partner rather than direct competitor but serves many of the same early-stage startup customers with overlapping banking-adjacent workflow tools.
Emerging players
- Carta: Carta is a larger cap table and equity management platform serving venture-backed companies; it overlaps with Capbase's cap table, equity issuance, and 409a valuation offerings but operates at a higher end of the market.
- doola: doola offers US company formation, bookkeeping, tax, and compliance for global founders; it competes with Capbase's combination of formation plus ongoing finance ops, especially for non-US founders forming Delaware companies.
Direct peers
- Clerky: Clerky is a direct competitor providing attorney-drafted legal paperwork for startup formation, equity issuance, and 83(b) elections, and was acquired by LegalZoom, giving it distribution resources comparable to Capbase post-Mainstreet.
- NorthWest Registered Agent: NorthWest is a direct competitor providing Delaware registered agent and LLC/Corp formation services; Capbase incorporates registered agent service into its subscription and competes head-on for new entity formations.
- Firstbase: Firstbase provides US company formation, EIN, and banking setup for global founders; it directly competes with Capbase in onboarding international founders to Delaware C-Corps and forming US entities.
- Stripe Atlas: Stripe Atlas directly competes with Capbase by helping founders incorporate a Delaware C-Corp, get an EIN, open a bank account, and access starter tools; both target first-time founders with bundled incorporation + financial tooling.
Broad incumbents
- LegalZoom: LegalZoom is a broad incumbent in business formation and legal paperwork (and now owns Clerky); it overlaps with Capbase's incorporation and legal document generation flows at a more SMB/consumer level.
- Gusto: Gusto is a broad incumbent in SMB payroll, benefits, and HR; post-Mainstreet acquisition, Capbase competes/cooperates with Gusto for onboarding flows where Capbase handles equity and Gusto handles benefits.
