Quo

What Quo does

Quo, formerly OpenPhone, is a San Francisco-based cloud communications company founded in 2018 by Mahyar Raissi and Daryna Kulya. The company provides an AI-powered business phone and shared inbox platform targeted primarily at startups, small businesses, and multi-location operators, with secondary traction among mid-market and enterprise customers such as Farmers Insurance, Keller Williams, Chicago Bears, Mercury, Supabase, and Visiting Angels. Its core offering unifies VoIP calling, business texting, shared phone numbers, team inboxes, and a built-in mini-CRM into a single subscription product accessible across iOS, Android, macOS, Windows, and web browsers, with no on-site hardware required.

Underlying the platform is Twilio infrastructure for messaging and voice transport, layered with proprietary AI features including the Sona 24/7 AI voice agent, automatic call transcription, AI-generated call summaries, and AI call tagging. Quo has positioned itself as the first business communications platform listed in Anthropic's Claude Connectors Directory via a Model Context Protocol server, and also offers a native ChatGPT app through OpenAI's Apps SDK, allowing natural-language management of communications inside both AI assistants. The product is complemented by integrations with Salesforce, HubSpot, Pipedrive, Slack, Jobber, Zapier, Make, and Gong, plus a public API and developer documentation.

Quo operates a per-user SaaS subscription model with three tiers, Starter at $15/user/month, Business at $23/user/month, and Scale at $35/user/month, plus usage-based pricing for the Sona AI add-on at $25/month for 4,000 credits. The company runs a primarily product-led growth motion with a self-serve 7-day free trial and a 20% discount on the first three months, supported by content marketing, SEO, and a sales-assisted channel for larger deals. As of 2025 the company served 90,000+ businesses and processed over 1 billion calls and messages, was backed by Y Combinator, and in September 2025 closed a $105 million growth financing round led by General Catalyst to fund go-to-market expansion.
