Get to know Antoni Gmitruk

Straight up, let me put you on to Antoni Gmitruk – this guy is the real deal. So, he’s the co-founder and CTO of Golf, an open-source platform that’s basically changing how companies build MCP servers. If you don’t know, MCPs are like these super complex, multi-component servers that need to talk to each other smoothly – think routing, auth, telemetry, error tracking – all that messy backend stuff. And Antoni’s team made it dead simple to ship those in production. Like, you can use a live server in under a minute. No bullshit.

But here’s the crazy part – Antoni started messing with tech when he was just 15. His first project? A fully automated 3D printer. The kid was already into building real stuff, not just coding for fun. And the crazy thing? He and his co-founder Wojciech have been building shit together since they were like 14, back in high school. That’s almost a decade of grinding, building, improving.

What really gets me is his vision – he’s all about a future where AI agents have their own internet, like their own access to all services. That’s what inspired him and Wojciech to drop out of university and go all-in on Golf. They saw a problem: building MCP servers is a pain, full of boilerplate, complicated configs, and long deployment times. So, they made Golf to fix that. Their open-source framework, GolfMCP, makes it stupid easy to define what your agents can do without needing to be a deep spec wizard. Plus, they threw in Golf Gateway – a hosted layer that gets you live deployment in under a minute, with real-time traces, error monitoring, the whole nine yards.

And get this – it’s already being used in production by companies. Like, they crushed it early on, and people are adopting it fast. That shows how much Antoni and his team really get the pain points of dev teams and solved them with not just some fancy tech, but practical, real-world solutions.

What does all this say about him? Man, Antoni’s the kind of founder who’s been obsessed with building from a young age. He’s not just in it to make a quick buck; he’s got this deep drive to make complex backend stuff accessible and expandable. Dropping out of college? That’s not just reckless – that’s pure passion and confidence in what he’s building. He saw a problem, had the skills, and just jumped in. That’s what startup life is all about – identifying a real pain, building the tools to fix it, and moving fast.

Bottom line: Antoni Gmitruk is a tech builder who’s been wired for this since way back. He’s the guy turning complex backend infrastructure into something that’s fast, open, and accessible. And he’s only just getting started.
