Meet Isabelle Ilyia

So check this out about Isabelle Ilyia – this girl is the real deal, no cap. She’s a straight-up tech whiz, and she just crushed it with her latest venture, Cedar. She’s a YC W25 alum, so she’s legit in the startup game, and she’s got that hands-on experience from big names like Figma and Notion – two of the most sick products out there. That’s where she learned how to hook users on complex tools and figure out the best ways to get them to actually use your stuff.

She studied at Georgia Tech, which is no joke – a solid tech background that’s clearly paying off. But what really pumps me up about her is her jump into Cedar in 2025, alongside Jesse Li. They saw a problem: apps are cool, but they’re complicated as hell sometimes, and users get lost or stuck. So, Isabelle and Jesse decided to build something that’s gonna change how we interact with apps forever. Cedar is all about those AI copilots inside apps – imagine having a super smart assistant that helps you understand, learn, and do stuff without bullshit or confusion. It’s like having a buddy who actually knows what they’re talking about, always ready to help you be productive.

What’s wild is how she’s focused on centralizing user knowledge and automating tasks with AI – basically making apps smarter, faster, and way more intuitive. That’s the future, right? No more struggling with ghost menus or endless tutorials – just smooth, AI-powered help that makes everything easier.

Starting Cedar wasn’t just about another startup – it’s about creating tools that enable people, cut through the noise, and push the whole industry forward.

Bottom line? Isabelle Ilyia is that rare mix of deep product know-how and bold vision. She’s not just building cool tech – she’s shaping the future of how we use apps. That’s why she’s so important. She’s the real deal, and she’s just getting started.
