Questions
Is the score just an AI opinion?
The evaluation is written by AI, but it is scored on 10 fixed startup dimensions and shows its reasons, red flags and counter-signals. Signals link to the discussion they came from, so you can check them yourself.
Do I have to subscribe to try it?
No. Signals, idea evaluations and one full project with its evidence are free, with no time limit.
What is in a Decision Brief?
One cited report for one project: summary, target customer, problem and evidence, counter-evidence, market wedge, product scope, distribution, economics, a 7-day validation sprint and kill criteria. It is a single $4.99 purchase, not a subscription.
