Kibo About
A small team. A big obsession.

A small team. A big obsession with calm finance.

Kibo is built by people who believe expense tracking should feel like jotting in a notebook, not auditing your life. Here's the story and the human behind it.

The team behind Kibo
Saul Molinero, who builds Kibo.
Built by one human
+ one very lazy cat

Saul Molinero

Builds Kibo

Senior Software Engineer with a decade of mobile and backend craft. I started Kibo because every other expense app I tried felt like homework, and I needed one for my own finances that didn't.

I write the Android client, the API, and most of the AI bits that make the magic happen. If you find a bug, you'll get an email back from me, not a ticketing system.

A bit of background
12+

Years building mobile

From early Android days to modern declarative UI. Apps with millions of users, performance budgets that mattered, and the discipline that comes with it.

Full-stack craft

Resilient backend services, modern data layers, and cloud-grade infrastructure. The kind of stack that lets a one-person team punch above its weight.

AI & machine learning, applied

OCR pipelines, NLP for transaction naming, prompt engineering. AI as a quiet helper, not a circus.

Community at heart

Former Android Developer Group & Google Developer Group organizer. Conference speaker, writer, and very loud advocate for sharing what you learn.

The product

Live on Google Play, used by a few thousand people across 10 languages (Spanish, English, French, German, Italian, Portuguese, Hindi, Russian, Japanese, Korean), so it works in more pockets than just mine.

Foundations

Built for trust, quietly.

The principles behind Kibo's architecture. Not a stack list (that stays out of public view, by design), but the qualities those choices guarantee for you.

Native & modern

A mobile experience that feels native to your device, with the latest design language baked in.

Encrypted by default

Your data is encrypted in transit and at rest. We can't read it casually, and we don't want to.

Globally available

Resilient infrastructure that stays up wherever you are, with privacy-aware regional handling.

AI that respects you

Smart features that help without compromising what's yours. Your data fuels your experience, not anyone else's.

Tested & deployed with care

Every release goes through automated checks before it ever reaches your phone. Ship slow, ship safe.

Always in sync

Your data follows you across devices in real time, with end-to-end consistency.
