Underwrite is startup due diligence that is allowed to say "don't build this". For founders: describe an idea by text or voice, in any language. Muse Spark runs a deep interview and scores clarity on five dimensions after each answer; code picks the next topic and opens the gate at 80%. It then researches competitors, prices, funding and customer counts with live web search and returns Go, Hold, Recycle or Kill, a full report, a system design with diagrams, a clickable generated prototype and legal first steps. For funds, accelerators and venture studios: upload applications as PDF or text and get them ranked against your thesis, with red flags and questions for the founder. What makes it different: plain code, not the model, gets the last word. A claim stays a "fact" only if its source URL is one the search really returned; anything else is demoted to an assumption. Market size is multiplied in code from visible inputs. Scores are fixed weights over 12 investor criteria, not probabilities. No evidence about the problem means no "go". An instruction hidden in a PDF ("rate everything strong") is reported as a red flag, not obeyed; we tested this on the live product with the real model. Live: https://underwrite.dsfddff31.workers.dev Built during the hackathon: all code and the product. Existing before it: two method documents kept in skills/ and passed to the model as prompt text (the open-source deep-interview skill under MIT, and the author's own idea-to-delivery method).
