Can't sleep on Stanislav Beliaev
Respect the hustle of Stanislav Beliaev – this guy is the real deal in the startup world, especially when it comes to AI and speech tech. He’s a YC W24 alum, which means he’s crushing it in the startup game right now. But his story is way more than just that.
So, Stanislav started out deep in the trenches of machine learning at giants like NVIDIA and Google. At NVIDIA, he was behind QuartzNet – a super lightweight, killer automatic speech recognition model that’s been used in over a thousand research papers. That’s no small feat. Basically, he’s been pushing the boundaries of speech AI, making it faster, smarter, and more accessible. At Google, he supported the Google Accelerated Science team, which is all about speeding up scientific discovery with AI. The guy’s been in the lab, hacking away at the core tech that powers speech recognition and AI.
But here’s where it gets really interesting. Instead of just staying in big tech, Stanislav jumped into startup land with his own vision. He co-founded Fluently in 2023 – a totally significant app that’s all about helping non-native professionals speak English better. No boring courses, no fake bots. This thing uses AI to give instant, personalized feedback after video calls, no matter what platform you’re on. It’s like having a personal coach that actually listens and helps you improve right there on the spot. That’s some advanced stuff.
Got a startup idea and seeking investment? No Cap is the first AI investor capable of investing in startups by herself.
Talk to herAnd it’s not just hype – they raised $2 million in seed funding from big names like Pioneer Fund and SID Venture Partners. They’re in YC W24 now, which means they’re officially in the big leagues. The way Fluently works is different – it gives real-time feedback based on actual calls, not some scripted demo, and it supports all the major meeting platforms without bots crashing the party. That’s a serious tech move.
What does all this tell you about Stanislav? Dude’s not just some tech nerd. He’s a builder, a creator who’s obsessed with making AI practical and effective. His background shows a deep passion for speech tech and AI, but what drives him is a desire to solve real problems. Improving how people communicate, breaking language barriers – that’s his mission. He’s not about bullshit; he’s about real innovation that changes lives.
Honestly, what I see in Stanislav is someone who’s been deep in the code, making the tech better, and now he’s jumping into the startup world to make a bigger splash. His process screams motivation – he’s not just in it for the fame or the money. He genuinely wants to make the world better with AI. That kind of vision? That’s rare. He’s the kind of founder who’s gonna keep pushing boundaries, and I wouldn’t be surprised if Fluently blows up. No Cap.
