Check out Jonty Knox

Yo, you gotta hear about Jonty Knox. This guy’s the real deal in the startup world. He’s an Aussie dude who jumped into tech early and just crushed it across the board. Started out at Huawei-no small feat-closing billion-dollar deals with BT. That’s some serious enterprise cred right there. Then he jumped into product roles at Voxbone, which was a major success story too-so much so that Bandwidth scooped it up for over half a billion bucks in 2020. The dude’s been in the thick of the big leagues, no cap.

But that’s just the start. Jonty’s not the type to rest on his laurels. He’s got that entrepreneurial fire burning bright. He co-founded CustomerOS, which is part of YC’s S22 batch-meaning he’s now riding with the best of the best in Silicon Valley. CustomerOS is all about AI agents that supercharge sales, marketing, and customer success. Think about it-another step into the future, helping companies automate and scale like crazy. That’s what gets him up every morning.

Before all that, he led product at Otto Finance, a fintech startup backed by Sequoia. The fact that Otto made it into Sequoia Arc’s first batch? That’s not a coincidence. It shows Jonty’s got the Midas touch for picking and building winners. Plus, he’s an angel investor in over 20 pre-seed startups-yeah, he’s out there backing the future trend before it’s even a thing.

Talk to her

And he’s based in London now, but he’s got that global perspective. Studied at the University of Aberdeen-shoutout to the UK-and even took courses at MIT edX. So, this guy’s got the brain, the hustle, and the global network.

What’s the story here? It’s simple. Jonty’s all about building stuff that matters, leveraging tech to push boundaries, and helping other founders crush it too. He’s been in the trenches from enterprise deals to startups, always chasing the next big breakthrough. His process says a lot-he’s motivated by innovation, by having an effect, and by the thrill of building something from nothing that actually changes the game.

Honestly, if you wanna understand what it means to be a modern tech founder with real chops-someone who’s seen the inside of big deals, big exits, and now building the future-Jonty Knox is it. That’s why he’s worth paying attention to.
