Certifii is a UK fintech that gives private companies something they've never had: a standardised, forward-looking credibility score. The Certifii Trust Index takes a founder's own inputs, builds fully integrated financial statements through a double-entry accounting engine, and returns a deterministic seven-axis score in around 90 seconds, anchored to IFRS, ISA 520 and LMA DSCR conventions. That matters because the UK's 4.9 million private companies are judged today on stale filleted accounts, leaving banks, lenders, credit insurers and investors deciding on backward-looking data. Certifii closes that gap between what a business says and what it's likely to do. The platform is free to SMEs, which keeps the index neutral and the data deep, and it's paid for entirely on the demand side by the institutions that use the scores through triage reports, a decisions API and portfolio monitoring. In short, Certifii is credibility intelligence for private capital: where capital meets truth.
