Getarch

Arch (getarch.com) is a San Francisco-based software company selling AI-driven marketing and revenue automation to residential home services contractors in the HVAC, plumbing, electrical and drain trades. The product connects natively to the ServiceTitan field service management system and layers external datasets — building permits, real estate transactions, property characteristics and financial signals — on top of a contractor's own CRM records. From this combined data the platform constructs an "ideal customer profile" describing the attributes of a contractor's most valuable customers (for example square footage, year built, lot size and tenure ranges) and then identifies lookalike households in the service territory that match that profile.

The platform is organized around three stated functions: finding new prospects, protecting existing customers by detecting early churn signals and automatically launching retention campaigns, and growing revenue by surfacing cross-sell and upsell opportunities, including by parsing technician notes to trigger relevant offers. It also re-engages unconverted leads. Arch describes an end-to-end workflow of ingest, analyze, act and measure: audiences are enrolled automatically into email and direct mail campaigns, with the vendor handling postcard printing, shipping and delivery, and results — calls, emails, QR code scans and match-backs — are attributed and written back to ServiceTitan. Built-in A/B testing with holdout groups is offered for campaign optimization.

Arch frames its market problem as the "leaky bucket": according to the company, the average HVAC contractor loses 36% of customers annually while the best contractors lose 8%. The company also markets a benchmark database it describes as built from performance data across thousands of contractors, used to compare a customer's churn, lead coverage and growth potential against trade-specific segments. Its stated longer-term vision is an "autonomous revenue engine" unifying data across verticals and adding automation and financing so that households adopt upgrades, positioned by the company as supporting home sustainability and an infrastructure transition.
