Hello YC.
dIAry is the first personal assistant that helps you be, not do. You write about your day; it talks back and builds a map of who you are.
More about us ↓
The app isn't built yet. What exists is a clickable design prototype with sample data and no engine connected, and a measured extraction instrument. No external users.
About us
We're Álvaro and Fabio. We met at 12 playing competitive basketball at Real Canoe in Madrid, played together for years, and have been friends ever since.
We're building dIAry, a personal assistant that helps you be, not do. Every statement it makes about you links to your exact words and the date you wrote them, and you can refute it. The app isn't built yet.
Álvaro Molina, CEO. Designs the product and the strategy, built the clickable prototype, and wrote the manifesto. Played competitive basketball from age 7 to 18 for Real Madrid, Fuenlabrada and Real Canoe, and spent two years as a waiter to pay his own expenses and fund his side projects. Studied Management and Technology at Universidad Carlos III de Madrid.
Fabio Desio, CTO. Owns platform and infrastructure: the EU environment, encryption and cost per session. Wrote dIAry's backend, which is tested but not yet deployed. Is finishing a double degree in Mathematics and Computer Science at Universidad Autónoma de Madrid.
