I built this over a weekend to solve a problem I kept seeing: founders of profitable businesses have no idea what a PE deal actually looks like in practice. Most assume selling = all cash out the door. The reality is PE firms typically want you to roll 20-40% of your equity into the new structure. That rolled equity then participates in the second exit (when the PE firm sells the platform 3-5 years later, usually at 2.5-3x). The maths is surprisingly non-obvious. Rolling 30% at a 6x EBITDA multiple, then getting 3x on the rolled portion at second exit, often beats selling 100% upfront. The tool is three steps: enter your business details → get a valuation range based on sector-specific EBITDA multiples → use a slider to model cash at close vs. rolled equity at second exit. Tech: Next.js 14, Vercel, Tailwind. No sign-up required to see the valuation — email gate is only before the deal modelling step. Would love feedback on the multiple ranges and the UX flow.
