Our take
Business phones are a vital resource for many companies, but buying a second phone for your team can be an expensive prospect. Quo, formerly OpenPhone, solves this problem by replacing business phones with an easy-to-access app.
Quo leverages many of the advantages of a traditional business phone, allowing users to maintain work boundaries and privacy without the need for new, high-cost hardware. By specifically targeting people looking for a business phone number, Quo has attracted freelancers, small companies, contractors, and larger companies ready to modernize their existing phone systems.
Though there are competitors in the space, Quo's unique approach allows it to stand out from the likes of Aircall and Airpad. The company has seen significant funding, which it is investing in accelerated growth efforts, hiring, and the further development of its collaboration features and business tool integrations.
