What is Quo?
Quo is an AI-powered business phone system tool developed by Quo (formerly OpenPhone) that enables small and midsize businesses to unify calls, texts, and customer data for faster responses and streamlined communication. It features the Sona AI agent for 24/7 call answering and automated call summaries. Operating over Wi-Fi or mobile data, Quo provides virtual phone numbers (local and toll-free in the US and Canada) and a shared inbox for team collaboration. The platform's evolution from OpenPhone to Quo emphasizes a stronger focus on AI-driven intelligence and a connected approach to business communication, with enhanced AI capabilities highlighted in recent updates from late 2025 and early 2026.
