Rabbithole is being built with children, parents and educators from day one. As CPO I lead product vision, customer outreach and validation.

The product is in stealth, so here is the part I can show: how we work.

Pilots, partners and a waitlist in three weeks

Three weeks in, we had secured pilots with leading Finnish educational publishers, partnerships with major Finnish science museums, and meetings with partners and clients in Stockholm. The reception has been overwhelmingly positive, and there’s still a lot to iron out in the MVP. That’s exactly why we test so early.

Coached by people who built the companies you know

The Aalto Founder Sprint takes 12 students and puts them in a room with founders such as Mårten Mickos (ex-CEO of MySQL) and the founders of Sensofusion and Vinted check names / add Monica?.

What I take from it: far more work is possible than you think, as long as it’s focused and the goals are clear. I’d bring that same pace to a thesis.
