Free Tools
Answer the investor's what-if without rebuilding the spreadsheet.
Eight free tools for SAFEs, dilution, valuation, runway, option pools and co-founder splits. Each tool page works one example through, step by step.
The person who built the model is not in the room
An investor asks what a 10% option pool does to your stake. The answer lives in a spreadsheet, and the person who built it is not in the room. Pick the question below and answer it in one sitting.
Pick the question you need answered
Every result is a starting point for the conversation, not legal or tax advice. BildrX is not a law firm and does not give legal advice.
Run the numbers here, then keep them on a cap table
A calculator forgets your numbers when you close the tab. BildrX keeps the record: every share is an entry on an append-only ledger. Round modelling, SAFE conversion, vesting and Financial Tools all work from that record. Import your spreadsheet and it is live in under 30 minutes.
