Built to edit.
I build financial models for founders and investors. Start from a proven structure and edit it with AI, instead of guessing from a blank sheet. Run it as a spreadsheet, in your browser, or through your AI.
Plan the business. Raise the round.
Download it in Excel or Google Sheets. Every cell open and every formula documented, yours to edit however you want.
Build your cap table, exit waterfall, or fund economics live on the site. Nothing to download, and you can share a model by link.
Connect the MCP server and Claude or ChatGPT computes against the real Hemrock engine, the same math the web models run.
Proven structure
Every model is a structure that's already been used and tested: 55,000 people, 116 countries, since 2005. You start from something that works, not a blank sheet.
Edit with AI
Built so Claude, ChatGPT, and other AI tools can read and edit the model without breaking it. The proven structure is what makes AI safe to use here: it gives every edit a place to show up, so you can verify the output instead of trusting it.
Yours forever
Buy it once and it's yours. Open formulas, free updates to your major version, and no subscription.
Portfolio Reporting
Forward founder updates in any format, the AI pulls the metrics, and you get live portfolio dashboards and LP reports. Self-hosted and open source, running on your own infrastructure.
“I continue to use and recommend the Cap Table + Round + Exit model + other tools that [Taylor] provides. Some are free, all are valuable. (Have paid ~$300 and saved so much time and money over years as a Founder CEO, Angel, VC).”
