What Plunk does
Plunk (legally Lamda Inc., headquartered in Bellevue, Washington) operates an AI-driven, real-time home analytics platform for US residential real estate. The company's core technology is a Dynamic Valuation Model that continuously updates estimated values for over 104 million US homes by combining traditional real-estate data (property records, tax records, market performance metrics) with non-real-estate signals (buyer sentiment, macro-economic conditions, interest rates, lifestyle trends), machine learning, and computer-vision-based image analysis performed in partnership with Restb.ai across 400+ million property images. The product surface includes Plunk Home Value (up-to-the-minute AVM), Home Ticker (intra-day value changes), Market Insights (median list price, sale-to-list ratio, days on market), Plunk Remodel Value (predictive post-renovation value with Project Recommendations), Value Drivers, Plunk Refined Value, and the consumer-facing Plunk Pro subscription, all exposed through REST APIs and a self-serve developer portal.
Plunk monetizes through three primary streams: (1) B2B API access and platform licensing sold on annual quote-based subscriptions to MLS organizations, proptech platforms, and mortgage lenders; (2) white-label/embedded analytics licensed to partners such as Xome, Calque, Mosaik, RealtyCandy, Milestones, and BHR; and (3) the Plunk Pro subscription targeting real estate investors. Go-to-market is API-first and event-driven, supplemented by channel partnerships — most prominently The MLS/CLAW (20,000+ agents), the California Association of REALTORS strategic investment (217,000+ members), and SentriLock (500,000+ agents via mobile app). The company is venture-backed (a $6.5M seed round led by Unlock Ventures in May 2021, plus undisclosed strategic capital from C.A.R. in November 2022), operates with 11-50 employees, and has not publicly disclosed revenue.

- ATTOM Data Solutions: ATTOM provides property data, AVMs, and market analytics to real estate, mortgage, and proptech customers via APIs and bulk data products. It is a direct peer in supplying residential property intelligence and competes with Plunk for MLS and B2B data licensing deals.

Broad incumbents
- Zillow Group: Zillow operates the Zestimate AVM and is the dominant consumer-facing residential real estate platform in the US.

- CoreLogic (ICE Mortgage Technology): CoreLogic, now part of Intercontinental Exchange, is one of the largest US property data and analytics providers serving MLSs, lenders, and government agencies.

Both Plunk and Local Logic deliver geospatial and contextual real estate analytics and have explicitly partnered, reflecting strong product overlap in property intelligence.
- Offrs (by First): Offrs is a predictive analytics platform for real estate agents that uses AI to identify likely sellers and home valuation trends. It overlaps with Plunk's predictive analytics and Market Insights capabilities, though it focuses more narrowly on agent lead-generation and seller prediction.
Others
