Quo (formerly OpenPhone) is a San Francisco-based technology company providing an AI-powered business phone system for startups and small businesses.[1][2][3][5] It integrates calls, texts, contacts, and customer data into a shared workspace, featuring tools like shared numbers, AI receptionists (Sona), call summaries, transcripts, and CRM integrations with HubSpot, Salesforce, and Zapier to help teams stay responsive 24/7 without missing customer interactions.[1][2][5] Serving over 90,000 businesses, primarily small ones (noting 99.9% of U.S. businesses are small), Quo solves the problem of owners using personal numbers for business, enabling scalable, empathetic communication to build trust and drive growth.[1][2]
Quo was founded in 2018 by Mahyar Raissi and Daryna Kulya, who identified the issue while Raissi built tools for trade contractors: better communication led to higher earnings, but professionals lacked modern phone systems.[1] Drawing from small business family roots, they launched the first version as a simple, smart business phone, progressed through Y Combinator, and rebranded from OpenPhone to Quo while expanding into a full front-office platform.[1][3][5] Early traction focused on replacing personal numbers with professional tools, scaling to Series B funding with $56.12M raised, including a $40M round three years ago.[5]
Quo rides the wave of AI-enhanced customer communication, transforming legacy phone systems into intelligent front-office hubs amid rising demand for always-on, scalable tools in a remote/hybrid work era.[1][2][5] Timing aligns with small business digitization—99.9% of U.S. firms are small, yet underserved—fueled by market forces like CRM proliferation and AI adoption in sales/support, competing with Aircall and Vogent.[1][5] It influences the ecosystem by empowering SMBs to compete with enterprises, fostering a "modern economic renaissance" through resilient, human-centered communication that integrates with broader stacks.[1]
Quo is positioned for expansion beyond telephony into comprehensive front-office AI, leveraging its $56M funding and 90,000+ users to capture more SMB market share.[5] Trends like advancing AI agents, deeper CRM automations, and VoIP consolidation will shape its path, potentially evolving influence through ecosystem partnerships and global scaling. As it pioneers empathetic scaling for small businesses, Quo challenges the status quo, ensuring every customer moment builds lasting growth.[1][2]
Quo has raised $166.0M across 4 funding rounds. Most recently, it raised $110.0M Venture Round in September 2025.
