# Arch

> Arch is a San Francisco startup building AI marketing and revenue software for home-services contractors - the HVAC, plumbing, electrical, and drain businesses that keep American homes running. Founded in 2023 by Phil Krinner and Sacha Schmitz, Arch plugs into ServiceTitan and public property data to find homeowners likely to need work, catch customers about to churn, and auto-generate email and direct-mail campaigns. The company began by tackling the grunt work of heat-pump sizing and quoting, and has since broadened into an 'autonomous revenue engine' aimed at helping small contractors grow without a marketing department. It raised $6.2M in seed funding in February 2024 from Coatue, Floodgate, Gigascale Capital, ReGen Ventures, and MCJ Collective.
