About Twinnin

Built to give every human a say in the AI economy.

Twinnin is the consent, licensing, and data layer for human likeness in AI. We verify identity, structure rights, and route payment — so the humans whose faces train the models, populate the campaigns, and animate the synthetic actors get fair treatment, real money, and the right to say no.

Mission

We're not anti-AI.
We're pro-consent.

AI is already using human likeness at industrial scale — for advertising, broadcast, training data, synthetic actors, voice cloning, deepfakes. Almost none of it is licensed. Almost none of it pays the humans whose faces and voices it depends on.

Twinnin is a registry, a contract layer, and a payment system. One place where humans verify who they are, set the terms for how their likeness can be used, and get paid every time it is. The technology is permissionless. The economy around it shouldn't be.

The founder's story

Why I started Twinnin.

I spent 20 years in global brand leadership — Unilever, Vodafone — watching the marketing industry get faster, cheaper, and more synthetic. By 2024 the shift had become impossible to ignore: AI-generated faces were appearing in campaigns I worked on, in storyboards I reviewed, in social cuts approved without anyone in the room knowing whose face they were actually using.

I started asking the obvious question. Whose face is that? Did they consent? Did they get paid? The honest answer, almost always, was: nobody knows, probably not, and definitely not.

That's not a technology problem. The technology is here, and it's not going away. It's a market design problem. There was no registry. No standard contract. No payment rails. No way for a working actor, a model, a presenter, or any ordinary human to say "yes, you can use my face for this — and here's what I want in return."

"The laws of the day are not keeping up with the tech. So we built the rails the tech needs."

— Katrien Grobler, Deadline · April 2026

Twinnin started in 2025 as a private conversation between three of us — me, Lan, and William — about what the consent infrastructure for AI-generated likeness should actually look like. By early 2026 we had verified twins, working enterprise pilots, and a seed round closed with Google, NVIDIA, and SFC Capital behind us.

We're early. The work is real. The bet is that the next decade of AI deployment depends on getting this layer right — and we're building it the way it should have been built from the start.

The team

Three co-founders. One founding team.

Twinnin was incorporated by Katrien Grobler, Lan Prijatelj, and William Håkon Berg in 2025. Kayla Karmawan joined as founding team. Together we ship the product, hold the contracts, and answer every email.

FOUNDING TEAM

Kayla Karmawan

Chief Product Officer

Designs the product experience that every twin, brand buyer, and AI lab interacts with. Owns the interface where verification happens, licences get approved, and payments route. Joined as founding team in 2025 and shaped what Twinnin actually feels like to use — the calm, considered UX that lets a real human onboard in under ten minutes.

What we believe

Six things we won't bend on.

The product is a registry, but the principles underneath it matter more. These are the lines we won't cross, even when crossing them would be commercially convenient.

01

Consent is granular.

Not a checkbox. Not a sign-up agreement. Every use type, every territory, every duration is a separate decision the human can say yes or no to. The licence envelope is the moat.

02

The human gets paid.

Always. Every licence, every approved use, every deployment. If we earn, the humans whose likeness we represent earn first. 75% of every fee, agent or no agent.

03

Revocation is real.

Humans can change their minds. We honour withdrawal on a defined SLA, propagate revocations downstream, and log the lifecycle. Consent that can't be revoked isn't consent.

04

Hard exclusions are hard.

No political content, no pornographic content, no weapons, no minors in training data, no impersonation of real people. We turn down the money. Every time.

05

Provenance is the product.

Every consent is logged. Every approval is timestamped. Every fee is auditable. We hold the paper because we hold the risk, and we hold the risk because we hold the paper.

06

Founder-led, founder-answered.

Every enterprise deal starts at the founder level. Every difficult question gets a real answer. Every press call goes to a human, not a comms agency. That's the alignment.

Backed by

$3M seed. Three backers who get it.

We closed our seed round in early 2026 with investors who understand both AI infrastructure and the regulatory environment it operates in. No corporate strategics, no consumer-tech sharks. Backers who think in decades.

Strategic AI infrastructure investor. Brings perspective on what foundation model deployment looks like at planetary scale — and what the legal and ethical infrastructure underneath it should be.

The hardware layer of the AI economy. Brings deep insight into how synthetic media generation works at the GPU level, and where the bottleneck is shifting from compute to consent.

UK-based seed-stage investor, led the round. Conviction-led firm focused on technical founders building infrastructure for regulated markets. Active board involvement.
