Getting real about Tom Greenwald
So check this out about Tom Greenwald real quick. This guy is the real deal in the startup world, and he’s just getting started. So, Tom’s a YC S25 dude, part of that fresh batch that just crushed it in summer 2025. Before all this, he studied Computer Science at Northeastern – pretty solid background, right? But what really sets him apart is how he jumped into the trenches early on.
He previously worked as a Product Manager at SimpliSafe, handling special projects. That means he’s been in the game, running stuff that matters, figuring out how to make tech work for real people. And now, he’s the founder and CEO of Magnitude – a totally new kind of browser startup. Think open-source, vision-first browser agent that automates your browsing workflows using AI. Yeah, AI and automation in your browser – that’s next level. They’re also using narrated screen recordings to make it all easy to understand and work smoothly.
What’s crazy is that Magnitude was born in 2025, and it’s based out of SF – the startup hub. You can tell Tom’s got that hustle spirit; he’s jumping into the deep end with a bold idea that’s all about making browsing smarter, faster, and more automated. And he’s doing it with open source – that’s some next-gen thinking, really putting community and innovation first.

From running projects at SimpliSafe to now leading a YC-backed startup, it’s clear he’s driven by that itch to build something meaningful. He’s not in it for bullshit; he’s about real innovation, real impact. And honestly, his story screams one thing: he’s motivated by the desire to solve real problems with tech, and he’s not afraid to jump into the messy middle of it.
So yeah, Tom Greenwald – he’s that kid who studied CS, got some solid product experience, then said “fuck it,” and started Magnitude to change how we browse forever. Keep an eye on this dude. He’s only getting started, and I promise, he’s gonna be one of those names you’ll hear a lot more of.
