CalderR builds AI for property managers. Leasing leads get a reply and a tour. Repair requests go to the right vendor. Owner reports go out every month. Vendor invoices are checked before they are paid. Made for companies with 200 to 5,000 units.

Each repair is labeled, routed, and tracked until it is done. Emergencies escalate instead of sitting in a queue.

Why us
We build for operators, not investors.
Most AI vendors selling into property management have never managed a unit. We build systems based on operational reality. Every automation we ship is measured by hours saved, lead conversion, and owner retention. Not by AI buzzwords.
If your PMS is AppFolio, Yardi, Buildium, or Rent Manager, we know how to work with it.

What we believe
01
Operations beat brand
Hours saved and dollars earned. Not awards.
02
Depth over breadth
One tool, deployed deeply, beats ten generic ones.
03
Listen first
Operators know the business. We build second.
04
Human in the loop
The boring edge cases matter more than model size.
05
Explain it simply
If we can't say it plainly, we don't sell it.
