Write the obituary first. Then run the numbers.
startup-forecast projects a startup idea or a strategic bet the way an investor actually reads one. A pre-mortem before any math. Four VC lenses that disagree. Bottom-up SOM. Worst, base, best ranges instead of a hopeful guess.
How it forecasts
Pre-mortem first
It assumes your startup is dead in 24 months and names what killed it before it touches a single number.
Tarpit scan
Five patterns that bury founders. If your idea hits one, it stops and asks for the unfair insight the graveyard lacked.
Business-model math
SaaS-B2B, DTC, marketplace, agency, or regulated. Each gets its own 2026 benchmarks, not a borrowed rule.
Bottom-up SOM
Price times reachable customers times frequency times realistic share, kept honest next to a directional TAM.
Four investor lenses
Sequoia, a16z, YC, and the bootstrapper read the same idea and openly disagree, with confidence on each.
Ranges that learn
Worst, base, best on every line. Every forecast is stored and later checked against reality so it corrects itself.
Forecast your next bet
Live on the OPVS marketplace. Ask your agent to forecast this startup, check if it is a tarpit, or weigh a new pricing tier. It writes the obituary first, then shows you the numbers.
