Why I built Apostillum.

I spent years as a freelance video editor. I would work for months on a video that hit ten million views and made real money for my client — and I had no way to prove I touched it. Clients do not share who their editors are. That is bad for their negotiating position. So I was invisible.

I kept thinking about how you prove you did something real, from the other side of the world, with no paper trail.

Then I joined MrBeast. And we started getting hit with claims that the videos were AI generated. They were not. I was in the room. But there was no way to prove it — and that bothered me in a way I could not let go of. I tried to build it — a prototype, a way to prove you made something from the other side of the world with no paper trail. It did not work in the video industry. Editors are invisible by design, and the kind of proof AI-generation claims need is almost impossible to produce after the fact. I shelved it.

Then I read about the AI audit cases. Lawyers being sanctioned, doctors in malpractice suits, OpenAI spending two and a half months preparing logs before handing them to a court. Same problem. Completely different stakes.

I connected the dots and started building.
