We arrived in Barcelona with a plan: find a nice apartment, settle in, start our new life. What we didn't plan for was the 50 other people who wanted the same apartment.
Every time we found a place we loved on Idealista — great location, fair price, nice photos — we'd call immediately. "Sorry, we already have 30 visits scheduled." We'd show up to viewings where the line went down the stairs. We'd send our documents within hours and hear nothing back.
We weren't too slow. We just didn't know that Idealista's push notifications arrive 15 to 60 minutes after a listing is actually published. By the time your phone buzzes, the best apartments are already gone.
One of us is a developer. So instead of refreshing Idealista for the 200th time, we built something. A script that checks for new listings every few seconds and sends a Telegram alert the moment something matching our criteria appears.
We found our apartment in 3 days.
Then friends asked for it. Then friends of friends. Then strangers in expat Facebook groups. We realized this wasn't just our problem — it was everyone's problem. In Barcelona, Madrid, Paris, London, Dubai — anywhere the rental market is competitive, speed is the only advantage that matters.
So we turned our script into Prio.
Early 2025
Moved to Barcelona. Started apartment hunting on Idealista. Discovered the hard way that being "fast" wasn't fast enough.
Mid 2025
Built the first script. A Python script checking Idealista every few seconds. Found our apartment in 3 days. Friends started asking for access.
Late 2025
Added Fotocasa and Badi. One alert stream for all platforms. 22 beta testers in Barcelona, all finding apartments faster than they thought possible.
March 2026
15 platforms, 13+ countries. Investigated and validated coverage across Spain, France, Italy, UK, Gulf, Portugal, Poland, Romania, Netherlands, Belgium, Czech Republic, and Ireland. 46,000+ alerts sent.
What's next
Launching paid plans, expanding to France and Italy, building B2B tools for real estate agents. Adding new countries every month.
Speed is the only moat
In a competitive rental market, the person who knows first wins. Everything we build is optimized for speed — seconds, not minutes.
One alert, not three apps
You shouldn't need to check Idealista, Fotocasa, and Badi separately. One unified stream across every platform in your city.
Fair pricing, fair access
We offer a free tier because everyone deserves to find a home. Paid plans exist for people who need the extra edge.
Built by users, for users
We use Prio ourselves. Every feature exists because we needed it. No bloat, no features nobody asked for.
Prio is built by two people — not a VC-funded startup with 50 employees. We answer every message personally, we fix bugs the same day, and we care about this problem because we lived it. If you have questions, feedback, or just want to say hi — reach out directly.
