Work
US companies focusing on residential rental real estate have been developing many tools to solve fragmentation primarily from a B2B standpoint, but the consumer end is not keeping up with the latest technological advancements. Tenants, landlords, and service providers still suffer from substantial back-and-forth, unclear pricing, trust issues, and inconsistencies between task completion and communication, which current proptech AI SaaS tools fail to address systematically.
One huge bottleneck insiders have just started openly talking about is the incompatibility between existing digital infrastructure and operational workflows. To solve this, we are introducing a top-down multistakeholder agentic framework, where the agentic system acts as the proactive supervisor to orchestrate all stakeholders towards finishing a complete process loop. It's a complicated but very powerful system going against most playbooks used by traditional companies. Really curious to see what will happen in the next 5 years!
