Help us fix email for everyone.

We're a small team solving a massive problem. Come build with us.

Why Messybox?

Remote-First

Work from anywhere. We're distributed across time zones and built to be async. No mandatory meetings before noon (your noon). We trust you to do your best work wherever you are.

Real Impact

Email touches 4 billion people. Every feature you ship makes someone's workday a little better. This isn't a nice-to-have product — it's a tool people use every single day.

Growth

We're early-stage, which means you'll wear multiple hats, ship fast, and grow faster than you would at a big company. Generous equity, learning budget, and conference stipend included.

Open Positions

Don't see your role? Reach out anyway — we're always looking for great people.

Stop reading transcripts. Start reading summaries.

Every meeting distilled to decisions, action items, and the stuff that matters.
