Our Partners
Trusted by industry leaders
We work with leading design partners and integrate with best-in-class infrastructure providers.
One Platform
Everything your organization needs
From equity issuance to board governance, document signing to treasury management and compliance tracking. One integrated system — no more juggling Carta, DocuSign, board portals, and spreadsheets.
Purpose-built modules
Specialized tools for specific workflows
Two Interfaces, One System
Built for teams. Automated by default.
Your team uses the dashboard. Your code uses the API. Same system, same rules, same audit trail.
Your Team
Dashboard & UI
- 1Create your organization and set up your equity structure through a guided onboarding flow
- 2Manage equity, sign documents, and run governance votes from the dashboard
- 3Monitor treasury, review audit trails, and generate reports in real time
Your Automations
API & SDK
- 1Connect via API to issue securities, propose governance actions, and manage treasury programmatically
- 2Governance acts as the control plane — automations propose, but actions require approval before execution
- 3Automate routine operations while maintaining full compliance and human oversight
Shared Foundation
Both paths operate through the same system
Same compliance rules
Every action — whether triggered manually or via API — enforces the same transfer restrictions, approval workflows, and regulatory requirements.
Same audit trail
Complete, tamper-proof records of every issuance, vote, transfer, and corporate action — regardless of who or what initiated it.
Who It's For
One system for every organization type
Whether you're a startup managing a cap table, a fund administering LP interests, or a non-profit running board governance — CapSign adapts to your entity type and workflows.
Why CapSign
Your back office shouldn't need a back office
Traditional tools lock your data in proprietary silos and force you to stitch together a dozen vendors. CapSign is one open system that handles it all — fully automatable from day one.
- No Lock-In, Full Data Portability
- Your data is yours. Export your cap table to Open Cap Format, pull records via API, or migrate at any time. We're an open platform, not a walled garden.
- Compliance Built In, Not Bolted On
- Transfer restrictions, investor verification, and regulatory requirements are enforced automatically. Compliance happens by default — not as an afterthought.
- Fully Programmable
- Every operation available in the dashboard is also available via API. Automate equity management, governance actions, and treasury operations — with human oversight built in.
- Replaces Your Entire Stack
- Stop juggling Carta, DocuSign, board portals, and spreadsheets. One system for equity, governance, treasury, documents, compliance, fundraising, and fund administration.
