Roman Shemet

Yo, have you heard about Roman Shemet? The dude’s the real deal in the AI startup scene right now. He’s the founder of Cactus, this crazy open-source framework that just dropped in YC’s S25 batch – so he’s fresh off the boat but already making waves.

Roman’s story is dope. He’s been around the block with startups before – he’s got that entrepreneurial fire. He’s worked with Cactus, which is basically the Swiss Army knife for AI models. Think about it – you can run all kinds of models like LLMs, VLMs, embeddings, all on your phone or any low-power device. No bullshit cloud needed. It’s all offline, super private, and super fast. That’s a game changer, especially when everyone’s worried about privacy and data security.

And get this – Cactus supports models from HuggingFace like Qwen, Gemma, Llama, Mistral, and way more. Plus, it’s got bindings for React Native, Flutter, Kotlin – so devs can build cross-platform apps easily. It’s like the Uber for AI deployment. And Roman’s team even threw in features like MCP tool-calls for reminders, gallery search, message replies. If a task gets too heavy, it can fall back to the cloud, but the main gig is local inference. That’s some advanced stuff, especially for mobile AI.

What does this tell me about Roman? Dude’s not just a tech guy. He’s a problem solver who saw that AI’s biggest bottleneck is the cloud dependency and privacy issues. Instead of waiting for the world to catch up, he jumped into building a tool that makes AI more accessible, private, and fast. That’s the kind of mindset that separates founders who just follow trends from those who are really pushing the boundaries.

Roman’s process from presumably working on tech or startups to creating Cactus shows he’s got that relentless drive. He’s not satisfied with the status quo. He’s out here making tools that get AI onto your phone, not just in some cloud data farm. That’s big. It’s about decentralizing AI, making it more personal, more private, more immediate. That’s the future, no cap.

So, basically, Roman Shemet is this super sharp founder who took his experience and saw a huge gap in how AI is deployed. Instead of waiting around, he built something that could totally flip the script on privacy and ease of use in AI. He’s someone to keep an eye on because he’s working on the stuff that’s gonna shape how we all use AI in our day-to-day.
