About Bryan Onel

Yo, so let me tell you about Bryan Onel. This guy is the real deal in cybersecurity, and his story is pretty damn inspiring. He’s the CEO and founder of Oneleet, a YC-backed startup that’s blowing up in the compliance and security space. They hit $7 million ARR in under two years – no cap. That’s nuts for a security platform, especially one that’s all about cutting through the bullshit and actually helping startups get real security without the fake “security theater” most companies pull.

Bryan’s process is wild. He’s based in Amsterdam, but his background is as international as it gets. He’s got multiple BSc degrees in AI, Medicine, and Law from Vrije Universiteit Amsterdam – dude’s a total nerd but also a total bad-ass. Plus, he’s got a bunch of top-tier security certifications like CISSP, OSCP, MCSE, and even some fancy stuff around the MITRE ATT&CK framework. Basically, he’s been deep in the trenches of hacking, pen-testing, and info sec for over a decade, working freelance and at places like Sogeti Nederland. That’s a long grind, and it shows he’s legit.

What’s super interesting is how he co-founded Oneleet with his wife, Ora, and his best friend, Erik. These guys weren’t just jumping into some random idea – they saw a huge gap. Startups don’t need more bullshit security tools. They need stuff that actually works, that’s practical, and that’s transparent. Bryan’s been in the game long enough to know how the sausage is made, and now he’s building a platform that’s become the go-to in YC’s community for compliance and security.

Talk to her

What does all this tell you about Bryan? Honestly, he’s someone who’s been through the trenches – hacking, testing, managing security programs – and he’s decided to turn that experience into a solution that actually helps other startups protect themselves. He’s driven by a real motivation to cut through the bullshit and make security accessible, useful, and honest. That’s why he crushed it so fast – he’s not just building a company, he’s solving a real problem that he understands deeply.

So yeah, Bryan is a tech entrepreneur who’s been around the block, knows his shit inside out, and isn’t afraid to push for real change. His story shows what happens when you combine hardcore technical skills with a clear vision: you get a startup that skyrockets, helps the community, and keeps it real. That’s why he’s a guy to watch in the security space – he’s here to shake things up, and he’s already done some serious damage.
