Marketplace, two apps, web platform, own AI stack
Fixa is a complete ecosystem for home repairs in Spain: a marketplace with live bidding, two mobile apps, a web platform and a fully own AI stack with RAG, photo analysis and phone based job handling. Below you can read which problem it solves and how we built it.
A broken boiler in Spain means days of phone calls. Customers call one company after another, hear no prices anywhere and wait for a callback that never comes. Tradespeople on the other side have no way to get work without paying for leads, and never know which customer is serious.
In between, the customer also has to figure out what is actually wrong. Can the boiler be repaired or does it need replacing, how urgent is it, who can come by today? Those questions stay unanswered until someone finally shows up at the door.
Customers bounce from company to company without prices or time commitments
Tradespeople pay for leads without knowing which customer is serious
Nobody knows in advance what is broken, how urgent it is or what it costs
With urgent breakdowns it takes days before anyone comes by
Language barriers make it even worse for international residents
We built Fixa, a complete ecosystem for home repairs in Spain: a marketplace where customers describe their problem, AI analyses the breakdown and certified tradespeople bid on the job in real time. Three apps, one web platform and a fully own AI stack keep the entire journey running, from first question to finished repair.
The AI largely runs on our own infrastructure: a self hosted language model on our own GPU hardware, our own knowledge base of thousands of documents and a data collection engine that keeps feeding that knowledge base daily. No API costs per token, no dependence on a single vendor.
The customer describes the problem, optionally with photos, and certified tradespeople bid in real time within a fixed time window. One screen with all offers, prices and availability, instead of days of calling.
The customer photographs the breakdown and the system analyses what is probably going on. The tradesperson receives a prepared analysis, tool list and targeted questions instead of a blank incoming job.
A RAG assistant on a self hosted language model, backed by a vector database of thousands of repair manuals and fault documents. Answers are grounded in sources, with a safety policy that always refers dangerous gas and electricity jobs to a professional.
The moment the assistant detects a booking signal, including urgency and preferred date, a real job is created and bidding starts. The AI drafts the summary for the tradesperson itself, always in Spanish since the technicians are in Spain.
The AI calls. The customer gets a confirmation call presenting the three best offers and can book immediately. Tradespeople not yet on the platform get called, can place a bid over the phone and automatically receive an account with sms verification.
An autonomous pipeline collects repair documentation from the web daily, sorts it by brand and model with AI, and adds it to the knowledge base. Evaluation sets and user feedback continuously check whether the answers are right and feed the next round.
Once a bid is accepted the customer follows the tradesperson live on the map, with in app navigation for the technician and live activities on iOS. Arrival, working and finishing appear in the timeline automatically.
Customer and tradesperson call and chat with each other inside the platform, with conversation summaries afterwards. Phone numbers stay private on both sides.
Tradespeople go through an approval flow with VAT verification against the European VIES register. The staff panel manages users, companies, jobs, finances, risk scores per home and support tickets.
Stripe on the web, subscriptions through the app stores, credits for extra jobs. Four languages across the entire platform: Spanish, Catalan, English and Turkish.

“The boiler died on a Sunday evening. I took the photo, answered a few questions in the app and within an hour I had three bids. By nine the next morning the technician was at my door. I barely speak Spanish and for the first time that played no role at all.”
