The creator, Migon, notes that founders often present new technology with a headline number, and it is hard for non-specialists to tell what the underlying paper actually shows. Gapfinder takes a perovskite paper and identifies missing information, turning it into three investor questions and an expert-style spec sheet of 12 checks (for example area, certification, stability, task conditions, controls) marked against the supplementary information. An example on doping teen-led perovskite films shows how it distinguishes a material study from a solar cell paper and guides how much weight to give it.
