Here for Dominik Thalmann

Yo, so let me tell you about Dominik Thalmann, the guy’s a straight-up tech hustler. He jumped into the startup scene back in 2015 with this company called Sphere Secure Workspace. They were part of YC’s summer batch, S15, which is basically the startup Olympics, right? That’s where you gotta prove you got what it takes, and Dominik crushed it enough to get into one of the most competitive accelerators out there.

Sphere was based in London, a pretty hot hub for tech back then, and it was just him and Kubi Mensah running the show. Small team, big ambition. They built something in the security space, kinda like a workspace security platform, I think, and they went through YC, which is no joke. That’s where the real deal founders go to level up.

And get this, they actually got acquired. That’s a huge win because most startups never get to that point. It shows Dominik’s got the chops, the vision, and the hustle to build something useful. Dude’s been in the trenches, leading tech, making moves, and then selling the company, that’s the dream for a lot of founders. It’s like he’s been through the fire and came out the other side with a W.

Talk to her

From all this, I see a guy who’s super motivated, not just playing around but actually building real shit. He’s not afraid to jump into the deep end, work with a tight team, and turn ideas into something people want to buy. His process screams that he’s all about creating solutions, pushing boundaries, and having an effect. That’s the kind of founder who’s got the energy to keep going, even after a big win like an acquisition.

Bottom line? Dominik Thalmann is the real deal, a YC alum who’s proven he can build, lead, and sell. He’s the kind of guy who’s not just dreaming but actually doing shit that matters. And honestly, he’s just getting started.
