All about thomas hallaran
Buckle up for the great process of Thomas Hallaran – this dude is the real deal in the AI and content game. So, he’s a YC S24 founder, which already says a lot, right? But what makes him stand out is his backstory and what he’s built.
Thomas has been in the tech world for like two decades – no joke. He’s done everything from academia to working with startups, even the US Federal Government. That’s a crazy mix, and it shows he’s got serious chops in both high-level strategy and hardcore engineering. Basically, he’s been around the block, and he’s seen what works and what doesn’t.
A few years back, he teamed up with his co-founder Shaun Modi, and they jumped into some wild projects – like applying AI to Covid-19 logistics for the US Department of Health and Human Services and the Department of Defense. That’s some heavy stuff, solving real-world big problems with AI when the world was in chaos. It’s no surprise that this experience sparked the idea for Capitol AI, which they started in 2021.

Talk to herCapitol AI is all about transforming how media companies and publishers create content. They’re building AI tools that automate data storytelling and help media brands turn raw info into convincing stories – think Politico, Dow Jones, big names. They crushed it in YC’s Summer 2024 batch, becoming a revenue leader and landing a massive $1.3 million deal with a major media outlet. That’s no small feat, especially for a startup still figuring things out.
What’s really cool about Thomas is his focus on tech that actually changes the game. He’s into building platforms that automate insight generation, making data accessible and useful for business folks without needing a PhD in stats. His skills in product management and engineering are next level, and they’ve helped Capitol AI land serious enterprise contracts and raise Series A funding led by the Together Fund in 2025.
The thing that jumps out about Thomas is his motivation. The guy’s not just in it for the tech creds – he’s been driven by solving real problems, from global logistics to media innovation. He’s got that startup hustle, but also the depth of experience that makes his work legit. Starting Capitol AI wasn’t just about jumping into the AI hype; it was about building something that actually impacts how media tells stories and makes sense of data.
So yeah, Thomas Hallaran is a force in AI right now. He’s been grinding for years, and he’s finally hitting that stride where his vision is changing the game for media and content creation. No Cap, this guy’s just getting started, and I’m hyped to see what he crushes next.
