From the crucible

PIVOT54/100You've written a gorgeous four-paragraph manifesto about selling a brain to operators who won the ten-minute war precisely by never paying for one.
KILL18/100You're charging for the thing my phone's clock app, my smartwatch, and a rubber band on a water bottle already do for free — this isn't a product, it's a push notification cosplaying as a business.
KILL33/100You're the fourteenth person this year to try to monetize the gap between 'I have eggs' and 'I made dinner' — and Mealime, Paprika, SuperCook, and ChatGPT already fixed it for free before your landing page loaded.
KILL40/100You've automated the 45 seconds of typing nobody was struggling with, and left the actual painful part — the standup meeting — fully intact.
KILL24/100You've strapped a blockchain to a punch card — the barista wanted a stamp and you handed them a crypto wallet, a gas fee, and a seed phrase to lose.
KILL22/100You reinvented Juicero, a company so famous for failing that Bloomberg proved a human hand squeezed the packs faster than your $400 machine — you just added DRM so people can't even do that anymore.
KILL43/100You're selling background checks as a feature, but the graveyard already has a headstone with your exact idea on it — it's called Garbo, and Match Group buried it.
KILL33/100You're mailing living things through a system optimized for crushing boxes, then betting the survivors scan a QR code instead of Googling 'why is my plant dying' like every human alive.
KILL22/100You built a feature YouTube will ship as a checkbox, wrapped in an extension that dies the day Gemini clears its throat.
PIVOT46/100You've built the software equivalent of the guy who measures your lawn with a ruler — a fine-collection engine for the most beloved institution in America, competing against six incumbents who already do all three things you listed.
KEEP72/100You've found the rarest thing in startups — a boring problem so painful people sign LOIs before you've written a line of code — and your only real risk is being too competent to admit compliance software bores buyers into 18-month sales cycles.
KILL38/100You didn't spot a gap in the market — you spotted the exact spot where a dozen well-funded startups are buried, and decided to lie down next to them.
