Hi, I’m Hugo
I hold a PhD in cognitive ergonomics (industry-funded thesis at Renault) and I have been working in user and customer research for 10 years. I founded Personæ to help companies understand their customers and, above all, to make that understanding flow between teams instead of getting lost.
They understood their customers with Personæ
We were about to scrap a feature request because half the team swore customers didn't need it. Instead of scheduling five more interviews, I asked our persona, built from eight months of real interviews, and got the actual reasoning back in two minutes. Turned out the feature mattered, just not for the reason we assumed. We shipped it differently, and it became one of our top-adopted features that quarter.

Senior Product Manager
Before every launch, we used to argue in the room about which pain point to lead with. Everyone had a strong opinion, nobody had proof. Now I just ask the persona before the messaging brief goes out. Last launch, it told us the angle we were about to use wasn't the one that actually convinced people. We changed the headline two days before go-live. Conversion on that landing page came in 30% above our usual.
Julie K.
Head of Product Marketing
Our growth was stagnating right after we'd just hired new salespeople. We couldn't figure out why, so we dug in, and realized no one was aligned on our ideal customer, our target customer. We had a Notion page dedicated to our persona, but even so, everyone had their own definition. With Personæ we don't even ask the question anymore, everyone has access to the same up-to-date persona, and on top of that we can interview it. Thanks to that, our sales team became far more effective.
