Industry Mainstay

Community Phone is a verified Y Combinator (W19) company with estimated $10M+ ARR and 20,000+ customers, solving a critical infrastructure problem (copper landline sunset). Despite the submission containing extremely poor quality and exaggerated text (e.g., 'most people have used my product'), external verification confirms significant market traction and utility. The score reflects high underlying business value, heavily penalized in the Quality Factors for the unverifiable and lazy claims in the submission.

Description
Our solution lets a business get all modern voice features (re-route if busy, greeting menu and IVR, programmable caller ID, cloud voicemail, etc) on their existing office phone and existing employee cell phones. All employees onboard instantly, no wifi required, no app to download. Businesses should not be missing out on orders because they can only take one call at a time, and they shouldn't need an IT person in order to get a modern business phone system. Coming in 2022: APIs in the voice call itself.
