Why founders switch from Cake Equity to OpenCap Stack
The biggest complaints we hear from Cake users — and how OpenCap addresses them.
Your free tier should actually be free
Cake's free trial gives you 5 stakeholders — barely enough to cover a founding team. OpenCap's permanent free plan covers 25 stakeholders, 50 documents, and full API access with no time limit.
Pay $300/yr instead of $1,000/yr for the same coverage
Cake's Build plan costs $1,000/yr for 25 stakeholders with no ISO/NSO support. OpenCap's Starter plan is $25/mo ($300/yr) and includes option grants from day one — saving you $700 every year.
A REST API and AI tools are not enterprise-only features
Cake has no public API. OpenCap ships 60+ REST endpoints and 29 MCP tools on every plan, so you can automate workflows, integrate your data room, and query your cap table from Claude or Cursor without writing a ticket.
Open source means your data is yours
With OpenCap's MIT license you can audit every line of code, self-host on your own infrastructure, and export OCTA v2.0-compliant data at any time. Cake is fully proprietary — you are locked in to their schema, their servers, and their pricing decisions.
