8.3 billion faces, zero infrastructure: the AI likeness market nobody is serving

Katrien Grobler woke up on the 29th of December and saw a word written above her bed. Not metaphorically. She describes seeing the name in her mind's eye, getting up, and telling her team they were pivoting that day.

Funding stage: Seed. At the time of recording, Twinnin had inbound commitments of $3M against a $25M post-money valuation target and 2,000 signed-up twins, anticipating a Series A in 12 to 14 months if it hit revenue and KPI targets. Update: Twinnin will relaunch the Brand, Human Verified, and Defend Twin products, alongside several other significant partnership updates, on October 8, 2026. They will then go out to raise a $4M seed round across Europe and the US with Wilson Sonsini. Current valuation places them at parity with ElevenLabs at its own seed round.

The word was Twinnin.

She had spent the previous year running AI KAT, making AI-generated video ads for clients like Capital.com and Reckitt's Dettol brand. On one project she needed a trader character. Rather than generate a synthetic face, she pulled photos of an investor she knew, ran them through Nano Banana, and built the character. The client's first reaction was the whole business model in one sentence: is this a real person?

It was. He hadn't been asked. She called him afterward, apologised, and made him sign a licence. That awkward phone call is now a company.

Her argument runs on arithmetic she calls the math of human likeness. There are 8.3 billion people on the planet. Frontier labs have already consumed images of humans at a scale in the tens of billions apiece, and by 2030 she projects the training requirement climbing into the trillions. Models cannot reuse the same face indefinitely. They need novelty, and novelty means new humans. Meanwhile the legal ground is moving under everyone: the EU AI Act's obligations landed, Denmark is rewriting its copyright law to treat likeness as property, and the NO FAKES Act cleared the Senate Judiciary Committee unanimously in June 2026. Demand is accelerating. Supply is becoming illegal. There is no clearing house in between.

That gap is the company. Twinnin verifies a human with government ID and a liveness check, lets them set granular terms for how their face can be used, hashes the consent record so it is auditable, and routes payment when a brand or lab licenses it. Seventy-five percent goes to the human, always, agent or no agent.

Then there is the half of the market that wants nothing to do with any of it. When Deadline clipped her panel and posted it, the comments were not friendly. One person told her she looked like an Incredibles villain, which she thought was fantastic. Most of the rest were worse. She did not dismiss them. She built for them. The Defend product exists because she concluded that people who want to opt out have nowhere to formally do so, and that a documented, timestamped “no” is the only evidence that holds up when a deepfake surfaces.

The other half of this episode is about how she operates. She has been to a contrast therapy club in Canary Wharf more than three hundred times since April 2025. Sauna, then a three minute plunge at one degree, then sauna again, sometimes three cycles before a call. She does not describe it as recovery. She describes it as a forced thinking environment. You cannot leave, you cannot distract yourself, so the problem you brought in gets solved. Most of her best product decisions happened underwater at one degree.

On her desk there is a broken meditation board. She made it herself with words like destiny and hope on it, then broke it and wrote over the top: I'm the CEO of a fucking $10 billion company. When she gets stuck, she looks at it and asks how that person would handle this. Her framing is that if you behave like who you are today rather than who you intend to be, you never arrive. She has pink hair, wears what she wants, swears in VC meetings, and is explicit that she is refusing to shrink into the founder uniform to become investable.

Ryan opened with a story about being told he has dainty ankles. It goes downhill in the best way from there.
