Drillbit is an AI automation platform for residential home service contractors founded in 2023 in Austin, Texas and backed by Y Combinator (S24). Instead of positioning as a simple answering service, Drillbit sells full-time AI employees that handle the administrative and operational workflows of a home service business, from inbound calls through quote generation, payment collection, and ongoing customer support.

The platform combines an AI receptionist, lead nurture agent across text/email/voice, a quoting engine that turns job requests into editable quotes, an opportunity-identification agent that mines job history for follow-on revenue, integrated payments, and a 24/7 customer support assistant. The AI uses the contractor's existing CRM and technician calendars to determine availability, so bookings match the real dispatch schedule rather than a parallel system.

Drillbit is priced at $500/month per location for the full-time AI employee, with usage-based billing kicking in after quota. The company targets plumbers, electricians, HVAC, house cleaners, lawn care, landscapers, tilers, and roofers, and has publicly claimed booking rates 3x greater than the best human CSRs. Because Drillbit replaces CSR headcount rather than augmenting it, it's best suited to operators who want to consolidate office operations into a single AI layer.
