Our story

We were tired of writing the same email.

Oh Boiler started in late 2024, in a co-working space in Lisbon's Marvila district, after the third time the founder rewrote the same cover letter in a row. The third draft wasn't worse than the first — it was identical. It was the rewriting that felt wrong.

We're a four-person team — two writers, two engineers — building one tool: a place to store the structure of every letter you've already written well, so the next forty go faster without going generic.

"A man who can write what he means is a man who has won the day." — Joan Didion, paraphrased liberally and probably wrong
The studio

Boilerplate Studio

A four-person product studio in Lisbon, Portugal. We ship slowly, write often, and refuse to A/B-test the welcome email.

Mission

Make the writing you do twice worth doing once.

Our mission is small and specific. Most working adults write the same eight things a year, forty times each. That's three-hundred and twenty pieces of work. Maybe ten of them are letters anyone will remember. The other three-hundred and ten deserve to be fast, consistent, and good. Oh Boiler is the tool that makes them so.

We don't believe in writing as a productivity hack. We believe in giving you back the four Tuesdays a year you've been spending rewriting the same opener.

House style

A short list of things we won't do.

  • — Never auto-send anything.
  • — Never email you "tips and tricks".
  • — Never train a model on your templates.
  • — Never lock features behind enterprise tiers we wouldn't pay for.
  • — Never use the phrase "supercharge your workflow".
