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.

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

Equity
Governance
Treasury
Documents
Compliance

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.

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.
