Didit Takes Aim at Fraud With a Face-First Identity Platform and Pay-Per-Use Pricing

As fraud costs balloon across the internet and KYC-heavy industries juggle an ever-growing stack of identity checks, Didit is pitching a simpler story: one platform, one fast face scan, one predictable per-use price. Founded in 2023 and currently part of Y Combinator’s Winter 2026 cohort, Didit positions itself as “an all-in-one identity platform that lets humans prove who they are starting with a face scan.” The company claims to power the fastest identity verification in the market and to fight fraud by default rather than as an add-on bolted onto an expensive base fee.

Didit’s approach reflects a growing frustration in the identity verification market, where businesses are routinely forced to stitch together document checks, biometric liveness, sanctions screening, and device signals across multiple vendors, each with its own contracts, minimums, and dashboards. Didit’s bet is that an AI identity verification platform consolidating those checks behind a face-first flow – with simple pay-per-use pricing – will appeal to product teams who want to move fast and finance teams who want to stop paying for seats they do not use. The platform is designed around a humans-first premise: if you can credibly verify that a real person is on the other end, a lot of downstream fraud patterns become easier to detect.

The company was co-founded by brothers Alberto and Alejandro Rosas, whose backgrounds stretch from AI engineering and mathematics to professional tennis. Alberto, an AI engineer by training, is building Didit as what he calls the “unified identity platform for the internet.” Alejandro, a self-described obsessive problem solver, is architecting Didit’s identity infrastructure from first principles. Both played tennis at a professional level, an experience they say shaped their comfort with pressure and their appetite for long feedback loops, traits that translate well to building core trust infrastructure for the web.

The broader identity market is being reshaped by two concurrent forces: the rapid proliferation of AI-generated deepfakes, which is eroding trust in video and voice as standalone proofs of humanity, and the growing regulatory demand for stronger KYC across fintech, crypto, marketplaces, and online services. Didit sits squarely at the intersection of these forces. By treating biometric verification and fraud defense as a single layer rather than separate line items, the company aims to give product teams a cleaner primitive to build on.
