Jacob Fu

I'm a computer science student at the University of Waterloo, and spend most of my time trying to learn from people who are further along than me at the things I care about.

I've bounced around a bit

Right now I'm at Ramp in New York City, working on some problems in the accounting space.

Just before that I did a month-long contract with HyperWrite AI remotely in my hometown, on AI predictive writing.

That came after a term at Uber in Sunnyvale, building on the Safety Media Platform.

And it all started at HubSpot in Boston, where I worked on Sales Workspace in 2025 and came back the year after for the AI Content Editor.

and built a few things along the way

Recently I built Cotabby, an AI autocomplete for macOS. So far, it's gotten to 15k+ installs and 1000+ stars, and even landed a YC interview.

Back in high school I was obsessed with .IO games, so I made Metro Apocalypse, a multiplayer zombie tag game. It ended up with 248k+ unique players, 4.2M+ plays, and $2.5k+ in Patreon revenue.

and won a few hackathons
