The People

Meet the Team

Rentnoi is a four-person team. Two founders who spent years inside multifamily operations and property management software before building the product. Two specialists who bring operator-side customer success and financial-data engineering depth. Everyone here has worked in the industry the product serves.

We’re building Rentnoi in close partnership with operators.

If you manage 300–3,000 units and want daily NOI variance intelligence without a data team, we’d like to talk. Request a demo and one of us will be in touch directly.
