May 2, 2026 Launched FundSim — free interactive finance simulator for LBO, DCF, PE, VC & IB

Hey IH community — I just launched FundSim, a free browser-based finance simulator for students breaking into PE, VC, and IB.

The problem I was solving: finance education is locked behind expensive courses (Wall Street Prep, BIWS, etc.) that cost $200-500+. Students prepping for PE/IB interviews need to practice LBO models, DCF valuations, and M&A deal structures — but most can't afford the tools.

What FundSim does:
- LBO model simulator (adjust entry multiples, debt tranches, hold period, exit assumptions → see IRR and MOIC live)
- DCF calculator with full sensitivity analysis
- M&A accretion/dilution model
- PE waterfall distribution calculator (management fees, carry, LP returns)
- VC cap table simulator (pro-rata, dilution, liquidation preferences)

All free. No signup. No Excel. Runs in your browser.

I'm a finance student myself and built this because I couldn't afford the prep courses. Launched on Show HN and got good traction. Would love feedback from the IH community on pricing, growth strategy, and what features to build next.
