Housewhisper

HouseWhisper (legal name Real Estate Productivity, Inc.) is a Seattle-based AI platform for real estate teams and brokerages, founded by former Zillow executives. It acts as a 24/7 AI teammate that automates the full lead lifecycle through personalized voice and text conversations: a Lead Engine that re-engages and revives cold database contacts, a Rules Engine that routes leads to the right agent with fallback escalations, and an AI Teammate that handles CRM updates, follow-ups, scheduling, reminders, and administrative busywork by call or text. It connects to real estate CRM, dialer, and calendar systems via API keys with no data migration, integrating with Follow Up Boss, Sierra Interactive, kvCORE, MoxiWorks, Salesforce, Lofty, HubSpot, and others. Pricing is outcome-based (a small monthly platform fee plus referral fees on closed deals). HouseWhisper has raised roughly $10M in seed funding led by Mayfield. The company does not currently publish a public developer API, documentation, or SDKs.

Housewhisper is profiled on the APIs.io network. Tagged areas include Company, Real Estate, Artificial Intelligence, AI Assistant, and Voice AI.

Housewhisper’s developer surface includes engineering blog, signup flow, support, and 7 more developer resources.
