Pickmybrain, the Tallinn-based platform that turns professionals' expertise into AI-powered “Digital Brains,” has raised a $2.1 million pre-seed round from a group of business angels, including Garri Zmudze, an early investor in drug discovery company Insilico Medicine, and Raison.app, an investment platform with $250 million in assets under management.
Pickmybrain was founded by Sergei Verbitski, a serial entrepreneur with a background in AdTech, iGaming, and digital marketing. The company was formerly called WOIS.io before rebranding.
The platform works by training AI models on a specific expert's structured knowledge: interviews, articles, books, and recorded responses they upload and consent to.
The AI handles routine questions instantly, in any language, while high-value or personal queries go directly to the real expert via 1:1 asynchronous video, a combination the company says no other platform currently offers.

Experts retain full control over what the AI is trained on, and for those without a large digital footprint, the platform provides tools to record original responses that the AI then learns from.
The platform currently hosts over 1,000 professionals across sports, entertainment, and business. Named participants include Peter Vesterbacka, co-founder and former CMO of Rovio (the Finnish studio behind Angry Birds) and co-founder of Slush.
Paul Pogba, the 2018 World Cup winner who returned to professional football in March 2025 after his 18-month doping ban, reduced on appeal from an initial four years by the Court of Arbitration for Sport, was served.
And Bozoma Saint John, who has held CMO or equivalent roles at Netflix, Uber, Apple Music, and Pepsi. The platform integrates with wearables and supports both paid and free tiers for expert interaction.
The funding will be used to grow the team, scale into new markets, and improve the product. Pickmybrain's positioning sits at the intersection of two accelerating trends:
AI personas entering the mainstream, illustrated by Khaby Lame's January 2026 deal, in which the world's most-followed TikToker licensed his likeness for an AI digital twin in an all-stock transaction valued at $975 million, and growing demand among professionals for ways to share expertise at scale without becoming full-time content producers.
