We build small, sharp software products.
RumboLabs is a maker-run studio. We pick real problems, ship focused tools, and sweat the details so you don't have to. Here's what we're building.

RumboLabs is an independent, AI-native studio based in Barcelona, Spain, run part-time as a one-person shop by Facundo Farias. It's built on a simple belief: software should be small, fast, and genuinely useful. I work on a handful of products at a time, ship often, and listen closely to the people who use them.
It's fully bootstrapped — no VC, no investors — so every product is built to stand on its own and grow organically. I lean heavily on AI, but the right way: privacy is a first-class citizen here, and your data is yours, never the product. No bloat, no dark patterns — just tools I'd want to use myself.
- FocusedEach product does one thing, and does it well.
- AI-native, privacy-firstWe use AI throughout — with your data treated as yours, not the product.
- Bootstrapped100% self-funded — no VC. We grow organically, paced by happy customers, not ads.
- CraftedWe sweat the small stuff so the experience feels effortless.
