You should know Tim Glaser
You absolutely need to hear the story of Tim Glaser, this guy’s the real deal in the startup world. He’s a tech wiz who’s been crushing it for years, and he’s got that founder hustle you gotta respect.
So, Tim’s most well-known as the CTO and co-founder of PostHog, which he jumped into back in 2020 during Y Combinator’s W20 batch. That’s the big leagues, YC isn’t just some accelerator; it’s where founders go to prove they’ve got what it takes. And Tim? He did not just jump in, he built something that’s now a major player in open-source product analytics. Basically, he saw a gap in how companies understand their users, and instead of following the herd, he created a platform that’s all about transparency, flexibility, and empowering dev teams to own their data.
But this isn’t some random guy who just got lucky. Tim’s been around the block a few times. Before PostHog, he was grinding at places like Arachnys, Getindustrious, Westeon, Cloud9 IDE, and Techtwo Webdevelopment. That’s a laundry list of solid tech startups and companies where he held roles in R&D, product, and engineering. It shows he’s versatile, the guy can build stuff, lead teams, manage products, and figure out what actually moves the needle. He’s not just a coder; he’s a builder who gets how tech fits into business.

Talk to herWhat’s crazy is how all this adds up. Tim’s process screams hustle and a genuine passion for making tech better. He’s not doing this for a quick buck; he’s genuinely about creating something that lasts. That’s why PostHog took off so fast, because he and his co-founder James Hawkins knew what they were doing, and they weren’t afraid to challenge the status quo. They built a platform that’s open source, so anyone can jump in and use it, no bullshit, no locked-in ecosystems. That’s a big deal in the startup and dev world.
And being based in the UK but involved with YC, that’s a sign he’s playing global. He’s not just some local hero; he’s shaping the future of how startups grow and analyze their products. People look at him and see someone who’s all about innovation, leadership, and making tools that actually matter.
Bottom line? Tim Glaser is one of those founders who’s been through the grind, learned the ropes, and then turned that experience into something new. He’s the kind of guy who’s pushing tech forward because he cares about building real stuff that helps teams crush their goals. No cap, he’s the kind of person you wanna keep an eye on, because he’s just getting started.
