Didit bets AI agents make identity verification the internet's trust layer; $7.5M seed
Twin brothers Alberto and Alejandro Rosas build an all-in-one, AI-native identity API in YC W26, closing $7.5M seed as deepfakes make KYC obsolete.
Didit
What the business is
Didit sells programmable identity and fraud infrastructure: a single API that combines KYC, KYB, biometrics, AML and real-time transaction monitoring, with pay-per-use pricing and no contracts.
Starting capital：$7.5M total seed, including an additional $6M announced 2026-05-26; investors include Y Combinator, Pioneer Fund, Orange Collective, Founders Future, Phosphor Capital, SaaSholic, Rebel Fund and angels Tomer London and Taro Fukuyama.
How it started
Twin brothers Alberto and Alejandro Rosas founded Didit in 2023 after watching fraudsters defeat existing identity tools. Their bet was contrarian: instead of stitching together five to ten point vendors, they would build every layer from scratch — ID verification, biometrics, liveness, auth — as one AI-native API, and price it publicly with no sales-call gating. They joined Y Combinator's Winter 2026 batch and built specialized verification flows per country, optimizing across face types, skin tones, document formats and lighting conditions.
What happened
Didit closed $7.5M in total seed funding, with an additional $6M announced on 2026-05-26. The company reported $3.3M revenue in 2025, profitability, more than 30% month-over-month revenue growth and roughly 30 employees, serving 1,500+ customers across fintech, crypto, marketplaces, iGaming, mobility and government in 220+ countries and territories; 80% of its customers had never used an identity verification provider before. It also became the first identity provider validated by Spain's Financial Sandbox as offering NFC plus active-liveness verification equivalent to or more secure than in-person checks, against the backdrop of eIDAS 2.0 digital-wallet mandates.
How it ended up
Live and scaling: profitable with a $7.5M seed, listed on Launch YC in July 2026 with millions of verifications per month and 300%+ net revenue retention by month six, and expanding from KYC into programmable identity for AI agents, wallets and age verification.
Background
Didit was founded in 2023 by twin brothers Alberto and Alejandro Rosas, AI engineers who concluded that identity verification built for a pre-AI internet could not survive deepfakes, synthetic identities and injection attacks. Instead of wrapping legacy vendors, they built the entire stack from scratch — ID verification, biometrics, liveness and auth — as one API, and joined Y Combinator's Winter 2026 batch.
The product combines KYC, KYB, AML, biometrics and real-time transaction monitoring behind a single API with public per-module pricing, no contracts and pay-per-use billing. Didit says any developer can ship an integration in five minutes, or an AI coding agent can do it in a single prompt, and the company claims its verification flows are optimized per country across face types, skin tones, document formats and lighting conditions.
On 2026-05-26 Didit announced an additional $6M, bringing total seed funding to $7.5M from Y Combinator, Pioneer Fund, Orange Collective, Founders Future, Phosphor Capital, SaaSholic, Rebel Fund and angels including Gusto co-founder Tomer London. The company reported $3.3M revenue in 2025, profitability, more than 30% month-over-month growth, roughly 30 employees and 1,500+ customers across 220+ countries, 80% of them new to identity verification.
Didit also claims a regulatory first: validation by Spain's Financial Sandbox that its NFC plus active-liveness verification is equivalent to or more secure than in-person identity checks, positioning it for the eIDAS 2.0 digital-wallet wave. By July 2026 its Launch YC listing reported millions of verifications per month and 300%+ net revenue retention at month six, with the founders aiming to make identity programmable the way Stripe made payments programmable.
What has to be true
- AI-shaped bet: deepfakes and synthetic identities broke the assumption behind legacy KYC, giving a newcomer a reason to exist that incumbents' architectures could not easily adopt.
- Full-stack ownership: building models, biometrics and flows in-house let Didit avoid vendor stitching, control quality per market and price transparently, undercutting sales-led incumbents.
- Developer wedge: one API, five-minute onboarding and pricing visible before a call converted a generation of builders — and AI coding agents — that legacy vendors had never optimized for.
- Timing and proof: profitable growth with 80% of customers new to the category showed Didit was expanding the market, while Spain's sandbox validation built credibility for the eIDAS 2.0 era.
What can be applied
When an AI shock invalidates incumbents' models, owning the full stack beats composing vendors: Didit's in-house API allowed public pricing and fast onboarding, converting a sales-call industry.
Aftermath
As of late July 2026 Didit is profitable and scaling: roughly 30 people, $7.5M in total seed funding, 1,500+ customers worldwide, millions of verifications per month and 300%+ net revenue retention by month six per its Launch YC listing. It is moving beyond document KYC into programmable identity for AI agents, wallets, signatures, social profiles and age verification, aiming at a reusable identity wallet — with incumbents, new AI-identity entrants and the cost of building every country-specific flow in-house as the open challenges.
