According to @godofprompt, the Persona + Constraint Stack framework is transforming how Y Combinator partners review AI startup pitches by requiring exactly three paragraphs, exclusively data-driven arguments, and a binary 'Fund or Pass' decision, with explicit reasons for passing. This method, tested on 30 startup pitches, led to sharper, more actionable insights in a precise 150-word format compared to traditional reviews exceeding 400 words (source: @godofprompt, Jan 24, 2026). AI founders and investors can leverage this framework to streamline due diligence, eliminate bias, and ensure consistent, high-quality assessments—key factors for scaling AI portfolio management and enhancing investment outcomes in a competitive market.
