Numberline is a virtual phone system for small businesses. We build the phone infrastructure founders grow on, so they can focus on their business and leave the phone system to us.
Large companies have always had reliable phone systems, real support, and tools that connect to everything they run. Founders and small businesses got the same systems with features removed and per-user pricing left in.
We started Numberline to give founders that quality from their first call. Everything we build starts with one idea: we love founders.
Our promise is to support founders and help them grow their companies. We treat every customer the same, whether you’re a solo founder just starting out or a growing company with advanced needs.
Numberline gives a business a complete phone system on the phones its team already uses: a local or toll-free number, a greeting with extensions, call forwarding, business texting and WhatsApp in a shared inbox, and voicemail emailed with the recording, a transcript, and a summary. It connects to Slack, a CRM, and AI agents from the provider a business chooses.
A phone system has to work every time a customer calls. We take on the work a phone company is responsible for, so the businesses we serve never have to think about it.
Numberline is built by founders and engineers who have served hundreds of thousands of small businesses at earlier companies. We’re headquartered in Henderson, Nevada, and our team works from several locations.
Unlimited users, with no per-user fees.
