Property operators who learned to build with AI.
We're not an AI company that decided property looked interesting. We're property operators who got tired of losing leads at midnight and decided to build the tools we wanted to use.
YieldKey is built by a small team split between two backgrounds. One side runs Infinity Stays, a UK property operation covering long-let lettings and short-term rentals. The other comes from a scientific and pharma engineering background — building rigorous systems where mistakes carry real cost.
The two paths converged on the same observation: most operational work in property is speed-sensitive, repeatable, and a poor use of human attention. AI is now good enough to take it — if it's built by people who know the work.
Full founder bios coming soon.
YieldKey is built and operated by the same team behind Infinity Stays, our UK property operation.
Three principles. They guide every product call.
Operators ship better tools than vendors.
The people closest to the work make the sharpest software. We're operators first.
Speed compounds.
Replying first is the single highest-leverage thing in property. Everything else follows from that.
AI should disappear into your workflow, not announce itself.
YieldKey doesn't add a dashboard you have to babysit. It does the work and writes back to the tools you already use.
