Drillbit is an AI-powered back-office platform purpose-built for residential contractors—plumbers, electricians, house cleaners, landscapers, roofers, and other home service businesses. The platform automates the entire job lifecycle from lead generation to payment collection using AI receptionists and an LLM-based quoting tool on top of a proprietary CRM. Drillbit handles phone calls with homeowners and businesses at every stage: answering inquiries, coordinating scheduling, providing estimates, managing staffing, and processing payments. The company was founded in 2023 by Alex Seutin (Stanford CS/AI) and Liam, who previously worked together developing robots for industrial construction projects. Seutin brings hands-on experience from renovating homes and airstreams, which gave him intimate familiarity with the pain points in the construction industry. Drillbit's key insight was that existing CRMs suffered from massive churn because business owners felt like they were 'babysitting' the tool—doing 'homework' rather than getting value. Drillbit solves this by handling coordination in a familiar way: talking to 'employees' on the phone like real people, and having those AI employees engage with homeowners over the phone. The platform is designed to eliminate the estimated $675B/year in administrative overhead that contributes to home maintenance costs across the U.S. Drillbit is still in its growth phase as of mid-2026, actively seeking to onboard contractors across the home service industry. The company is Y Combinator-backed (Summer 2024 batch) and based in Austin, Texas.
