# Business and Professional Services - United States

226,500 leads, emails not included so you enrich them yourself · Free

226,500 US business and professional services companies: consultancies, agencies, legal and accounting practices, and B2B service firms, compiled for 2026. Every row carries the company and firmographic detail; emails are not attached, so you enrich the file yourself.

Who this is for: SaaS vendors selling into professional services, outsourcing and offshore staffing providers, bookkeeping and back-office firms, and agencies whose buyer is another agency.

Before you send: enrich and verify emails first, the Waterfall Calculator finds the cheapest provider order. This is a broad universe, so segment by sub-vertical before you write a line, a pitch that lands with a law firm dies at a design studio. Professional services skew Google, so run the enriched file through the ESP Segmenter and route the Microsoft slice separately.
