Our tiny team operates at massive scale 1 million 6 million AI images generated daily 1 trillion LLM tokens processed per month Life at Gamma You get energy from small teams doing big things. You love when design, code, and storytelling overlap. You default to action, even when the answer isn’t clear yet. You value details, but know when to ship and move on. You bring both the spreadsheets and the sparkle, equal parts workhorse and unicorn. You believe AI should amplify creativity, not replace it. You know kindness and intensity are not opposites. You like working with people who care deeply: about their craft, their teammates, and the users on the other side of the screen. Who we are Gamma is full of imaginative, passionate people who take their work seriously but not themselves. The culture is warm, a little quirky, and fueled by curiosity. It’s the kind of place where you’ll debate a pixel on Monday, laugh over someone’s keyboard setup on Tuesday, and ship something remarkable by Friday. We care about craft, move with intention, and don’t mind getting a little scrappy. It’s fast, creative, and occasionally chaotic — but that’s what makes it interesting. Here’s a bit about what it’s like to work here, from people on the inside We asked the team what makes Gamma, Gamma. Here were some of their answers: quirky, inspiring, fun, a little wild in the best way You can have an idea and just run with it. Everyone’s talented and humble — the mix keeps you sharp. We ship cool stuff, learn a ton, and laugh a lot doing it.
