We build AI the slow way.

Lume is a seven-person studio split between Brooklyn and Lisbon. We started in 2024 because we were tired of AI tools that felt loud, anxious, and designed to be used 14 hours a day.

Our belief

Most software is built to maximize attention. We think the best tools do the opposite — they finish the job and then disappear. AI gives us a rare chance to make software that respects your time. We don't want to waste it.

📌
We're not building an AGI lab. We're building three small tools, very well, for people who think for a living.

The team

We're researchers, designers, and engineers who've worked at places like Anthropic, Notion, Figma, and DeepMind — and at smaller studios you've probably never heard of. We meet in person every six weeks. The rest of the time we write a lot of memos.

Principles

  1. Calm by default. No badges, streaks, or notifications without a reason.
  2. Local first. Your work lives on your machine. The cloud is opt-in.
  3. Memos over meetings. If it can be written, it should be.
  4. Ship, then refine. Better a small thing in your hands than a big thing in a deck.
  5. Respect attention. Software should earn the time it takes.

Where we're going

Over the next year, we're focused on shipping Lume Notes to general availability, opening up our API to a small group of developers, and publishing a short series of essays on what calm AI looks like in practice.
