Our own AI model

FuelCast

We forecast fuel prices before they move. Every day, for every station, the model answers a single question: will this station raise its price within three days? For now it targets three markets — Spain, France and Italy — where it is strongest.

73,000+
stations tracked across Europe
21.4M
prices recorded since 2024
75–90%
hit rate of the most confident forecasts
0.96 c/l
average error of the 3-day forecast (ES)
  • A gradient-boosted model reads 18 signals per station — its own pricing rhythm, the behaviour of neighbouring stations and Brent crude momentum
  • For the 10% most confident forecasts, a price rise is confirmed in 75 to 90% of cases; random guessing would hit 21 to 58%
  • We strip VAT and excise duty from prices following each country's legislative calendar, so the model learns the market, not government decisions
  • We test strictly walk-forward — on days the model has never seen — and every model has to beat a simpler baseline

About us

Small team, huge reach

inBee, s.r.o. is a Czech AI development studio. We don't build decks for the drawer — we build products used by people all over Europe. Our GasBu is Europe's largest fuel price comparison app, Najdi Hajzl proves that even the most down-to-earth problem deserves a first-class solution, with Wonderbu travellers discover the world through maps made by people who have actually been there, and IslaBu tells you every morning which Canary Islands beach to head for today.

FAQ

What clients ask us

How much does an AI app cost to build?

It depends on the scope. Validating an idea with an MVP starts in the low tens of thousands of euros; larger products are quoted individually. After a free initial consultation you get a concrete proposal with price and timeline — within 48 hours.

How fast can you build an MVP?

We typically deliver a working MVP in a matter of weeks — usually 4 to 8 depending on complexity. The goal is to get the product into the hands of first users as soon as possible and keep developing it based on real feedback.

Can you integrate AI into our existing system?

Yes. We specialise in integrating LLMs (chatbots, agents, RAG, automated document processing) into existing business systems — from CRM and internal tools to customer support. Nothing has to be rewritten from scratch.

Who do you work for?

Companies and startups that want a digital product with real impact — from Czech businesses to clients across Europe. Alongside custom development we build our own products (GasBu, Najdi Hajzl, Wonderbu, IslaBu), so we know what running an app with thousands of users takes.

How does the collaboration work?

We start with a free consultation where we go through your plan together. Within 48 hours you get a proposed solution with price and timeline. Then we work in short iterations — you see results continuously and can adjust the brief as we go.
