What HelloData.ai does

HelloData.ai operates an automated multifamily market analysis platform that aggregates daily data from more than 250,000 property websites, surveying 38.5M+ units across 2.1M+ U.S. properties with 99% market coverage. The platform is used by roughly 30,000 multifamily professionals, including the largest U.S. multifamily owner, the largest manager, and a large share of the NMHC Top 50, across five target segments: property managers, investors, developers, brokers, and PropTech companies. Its core products are Automated Market Surveys (rent comps), Market Analytics (map-based trend analysis), Development Feasibility Analysis, Rent Roll Analysis (LLM-driven), Financial Analysis (NOI underwriting), Query Builder, AI-Generated Reports, and a PropTech API suite.

The platform is powered by a multi-modal AI stack that includes computer vision models used for property quality scoring (QualityScore, 1-10 scale) and identification of 200+ amenities and finishes from listing photos, a proprietary LLM for concession extraction and effective rent calculation, NLP for unit attribute extraction, ML models for rent comp selection and record merging, and anomaly detection systems. Disclosed accuracy metrics are 97% match with actual rent rolls, 9-out-of-10 alignment with appraiser comp selections, and rents within 3-4% of actual leased rents on a daily refresh cadence.

HelloData monetizes through a SaaS subscription with two published tiers (Standard per-user and Portfolio per-unit, the latter including unlimited users, SSO, and API usage at $0.10 per call) plus enterprise and API terms negotiated via sales. Go-to-market is tri-channel: a self-serve 7-day free trial, a direct enterprise sales team, and an API/OEM channel for PropTech resellers. The company was founded in 2023 by Tim Gamble, Marc Rutzen, and Nico Lassaux—previously of Enodo and Walker & Dunlop—was bootstrapped rather than venture-funded, and was acquired by Grace Hill in April 2025.
