The origin
It started on a napkin, in November 2024.
As a consultant at Engel & Völkers in Madrid, one question kept me up at night: how do I talk to a homeowner before they decide to sell on their own through a portal? By the time the listing appeared, the conversation came too late. After many months looking for an answer, I sketched on a napkin a system that would spot owners intending to sell, so we could offer them advice before they published anything, always with their consent. That is how ATLAS was born. Caelum was founded in July 2025 to turn that idea into a company. Fernando Stimac Jaén, founder.
The opportunity
By the time a property reaches the portal, the owner has already decided to sell it alone.
Many owners sell or rent on their own because they think it is easy, and end up with a poor price or a bad tenant. ATLAS makes it possible to offer them advice when they start thinking about selling, before the listing.
A late conversation
The owner thinks selling alone is easy and lists the property. They often end up with a bad deal, and the agency arrives after the decision is made.
Scattered data
Land registry, public records, official gazettes and portals sit in sources nobody brings into one view.
Manual sourcing
It depends on each agent’s personal network. It does not scale without more people.
The solution
Three AI agents, one decision chain.
- Scout spots intentCross-references public signals and gives each property a sale-intent score.
- Director routes itAssigns each opportunity to the right professional, always subject to the owner’s consent.
- Consultor supports the agentAn interface for the human agent that learns from every outcome and improves the model.
Why invest
Three reasons to come in now.
Compliance as an edge
ATLAS is built with GDPR and the AI Act at its core: analysis never authorises contact, only the owner does.
Recurring revenue
Tiered SaaS for agencies and a subscription for homeowners after two free valuations.
Network effect
Every outcome an agent records improves the score for every client.
