Henry Ai lands $16.5M Series A from FirstMark to automate real estate agent admin

Henry Ai, a startup building artificial intelligence tools for residential real estate agents, has raised a $16.5 million Series A round led by FirstMark. The company develops software that automates administrative tasks tied to closing a home sale, including document generation, compliance checks, and transaction coordination. Instead of requiring agents to manually shepherd deals through disjointed systems, Henry Ai ingests contract data and uses large language models to produce the necessary paperwork and flag potential issues.

The $16.5 million Series A was announced on July 29, 2026. FirstMark, a New York-based venture firm known for backing companies like Pinterest and Shopify, anchored the round. The capital is earmarked to scale the engineering team, accelerate product development, and grow go-to-market efforts as the company pushes to capture a larger share of the real estate technology market.

Residential real estate agents spend a significant portion of their time on non-revenue-generating activities. Industry surveys regularly show that administrative overhead, compliance management, and transaction coordination consume over half of an agent’s working hours. Henry Ai positions its platform as a way to offload that burden, letting agents focus on client relationships and closing more deals. The company competes with a mix of legacy transaction management software and newer AI-native entrants targeting the proptech space.

The funding arrives during a period when mortgage rates and housing inventory constraints continue to pressure agent commissions and brokerage profitability. Tools that promise to reduce back-office costs have gained traction with large brokerages seeking margin relief. Henry Ai’s ability to automate compliance documentation also addresses a persistent liability concern for brokers, as errors in disclosures or contract timelines can lead to lawsuits or regulatory penalties.

FirstMark’s investment signals conviction that the real estate industry’s administrative layer is ripe for AI-driven consolidation. The firm has previously backed vertical SaaS and AI application companies across regulated industries. With the new funding, Henry Ai plans to deepen integrations with multiple listing services and brokerage CRM platforms, aiming to become the default transaction backbone for agent teams and independent brokerages.
