Y'all need to know Gideon Ebose

So check this out about Gideon Ebose. This guy’s the real deal in the startup world. He’s a YC F24 alum, and he’s crushing it as the co-founder and CEO of Rulebase, a company that’s actually changing the game in fraud detection with AI. Basically, they build these smart agents that sniff out voice-based fraud in finance – banks, fintechs, you name it. It’s crazy cuz they’re cutting investigation times down like 90%, making everything way safer and faster. No cap, this is the kind of tech that could save billions and stop scammers in their tracks.

But Gideon’s story didn’t start there. Dude’s been in the game for over six years, mainly in product design. He’s worked at giants like Goldman Sachs and Microsoft, so he’s no stranger to the big leagues. He’s also been a lead product designer at Gatherwell, guiding them from startup to getting bought by Jumbo PLC. Later, he helped build Microsoft’s virtual communication tools for hospitals – yeah, that’s some serious enterprise-level stuff.

What’s dope about Gideon is how he marries business and tech like a boss. He’s got an Economics degree but also knows how to build defensive systems for huge financial institutions. So, he’s seen the chaos of finance from all angles – the risks, the loopholes, the bullshit. That’s what drove him to start Rulebase, focusing on voice fraud because it’s a huge problem. Voice scams are sneaky as hell – people don’t even realize they’re getting duped until it’s too late. Gideon saw that gap and jumped into it, creating AI that automates investigations and cuts down the hassle.

He’s based in the U.S. but still keeps strong ties to Lagos, Nigeria – I think that mix of cultures and experiences fuels his innovation. He’s all about using tech to fight real-world problems, and his process shows he’s not just in it for the biz fame – he genuinely wants to make finance safer, smarter, more trustworthy.

Bottom line? Gideon Ebose is one of those guys who’s been around the block, learned the ropes, and then flipped the script with Rulebase. He’s proof that if you combine hustle, smarts, and a mission to solve big problems, you can build something that actually matters. That’s why he’s someone to watch – the kind of leader who’s not just chasing unicorns but actually changing the game.
