OpenPhone Rebrands to Quo, Raises $105 Million in Growth Financing

Quo(formerly OpenPhone), an AI-powered shared space bringing calls, texts, and contacts together, led by Mahyar Raissi and Daryna Kulya, has raised $105 million led by General Catalyst's Customer Value Fund and with participation of existing investors Craft Ventures, Slow Ventures, Garage Capital, and Y Combinator. 

OpenPhone launched in 2018 to help businesses build stronger customer relationships, originally described as “phone meets CRM.” Over time, the name only told part of the story. Quo better reflects the full vision as a customer hub with phone at its center—helping businesses win and retain customers. The focus remains on building great products and ensuring no opportunity is missed.

Major upgrades are launching for the voice AI agent Sona, built from customer insights. It is now available for free on all plans through a tiered, usage-based model, with every customer receiving 10 free calls per month. Sona can handle more sophisticated scenarios, be trained on custom jobs, and transfer calls to a human when needed. Thanks to customers for trusting Sona to power their communications, and to the team for the dedication that made this milestone possible.
