Breakpoint Engine™ · Founder finance with the AI you already use
Keep your company’s financing and equity records in files you control. Work through fundraising, capitalization, valuation, and founder-equity questions with ChatGPT, Claude, Codex, Cursor, Claude Code, or other compatible AI tools.
When the work requires precise financial mathematics, Breakpoint Engine calculates it deterministically.
No credit card. Free compute every month.
Your AI reasons. Breakpoint Engine calculates. Same inputs. Same calculation. Same result.
You should not have to learn valuation terminology or rebuild a financial model before understanding what a financing decision does to your company. Start with the founder question. Your AI works through the context; Breakpoint performs the financial engineering underneath.
Are our financing records complete?
Reconcile executed documents, approvals, and capitalization with your AI; keep missing evidence visible.
When does preferred convert to common?
Calculate the exact economic conversion points across the security stack.
What evidence is missing for our common-stock valuation?
Organize dated support and unresolved assumptions before calculating.
Which term sheet is actually better for us?
Look beyond the headline valuation to compare what founders, employees, and investors receive across outcomes.
What does increasing the option pool really cost us?
Understand who bears the dilution and compare pool sizes before agreeing to the terms.
Which investor preferences should we push back on?
See how liquidation preferences, participation, and conversion terms change what is left for common shareholders.
Could a different price or raise size serve us better?
Compare capital raised, dilution, and ownership across financing alternatives.
How do we explain equity value to our team?
Show how common shares and options participate at different exits, with the assumptions and tradeoffs made clear.
How could this deal affect our next round?
Explore higher- and lower-priced future rounds to understand how today’s terms could carry forward.
What would this counteroffer actually change?
Isolate one negotiating lever and quantify its effect before taking it back to investors.
Open-source founder war room

Open skills guide your AI through organizing records, checking what is missing, and preparing financing and valuation analysis. Keep each dated case—sources, management answers, calculations, verification, and reports—so the next decision builds on the last.

How it works
Your AI reasons. Breakpoint Engine calculates. The AI interprets your questions and explains the results; every number comes from a deterministic financial-engineering solve.
Describe the capitalization structure and financing terms conversationally.
Ask follow-up questions about breakpoints, dilution, preferences, ownership, and economic outcomes.
Alter one financing term or assumption.
Breakpoint Engine deterministically solves the modified structure.
Preserve alternatives and compare outcomes side by side.
Confirm the numbers came from Breakpoint Engine — not language-model-generated arithmetic.
Established AICPA/FASB methodology. An audited computational foundation. Breakpoint Engine delivers deterministic OPM calculations for complex financing structures — preferred terms, SAFEs, options, warrants, and founder common, priced across the full range of company outcomes. Your AI guides the exploration; the engine supplies consistent, reproducible calculations.
Computational analysis, not an independent 409A safe-harbor valuation opinion or legal, tax, or investment advice. Same inputs. Same calculation. Same result. Trace engine-derived figures to the recorded solve and the assumptions behind it.
