Mobile-first products
We design and ship apps that work on the phone in your pocket — built for the moment a user actually needs them, not for a slide deck.
Seralos Ventures, S.L. · Spain
Software that helps people find their footing in Spain.
Seralos Ventures is a small Spain-based venture studio. We build mobile apps and AI-powered tools for newcomers, expats, and anyone navigating Spanish life and bureaucracy for the first time.
Our first product, Guiri App, helps international residents understand official Spanish letters in plain language.
Overview
A studio, not an agency.
We don't take client briefs. Seralos builds and runs its own products — funding them, shipping them, and supporting the people who use them. That focus lets us pick problems worth solving properly, and stay with them long enough to get the details right.
What we do
How we work.
AI where it earns its keep
We use language models to translate, summarise, and explain — turning dense documents and unfamiliar processes into a clear next step.
Products for newcomers
We focus on people navigating systems they didn't grow up with: expats, international residents, and anyone facing a foreign bureaucracy.
Studio-built ventures
Seralos is a venture studio. We start small, ship early, and grow products in-house rather than spinning up agencies or one-off contracts.
