OpenPhone, which offers businesses a single phone number that entire teams can access through its iOS, Android apps, raises $14M Series A led by Craft Ventures
OpenPhone, a company setting out to replace “antiquated” business phone systems, has raised $14 million in a series A round of funding led by David Sacks' Craft Ventures.
Context & Ripple Effects
In late 2020, OpenPhone raised a $14M Series A from Craft Ventures to push its core pitch: one business number shared across a team through iOS and Android apps, replacing desk-phone hardware and legacy PBX systems for small businesses. Craft's lead matters because David Sacks' firm was reportedly targeting around $1 billion for a new fund, giving the bet room to compound.
The round aged well: by April 2022 OpenPhone had converted this seed of momentum into a $40M Series B led by Tiger Global, lifting total funding to $56M. The competitive set was also consolidating capital — European rival Ringover pulled in a €10M Series A months later for cloud voice and SMS.
First-order effects
- OpenPhone gets runway to scale its shared-number apps beyond early SMB adopters, while Craft Ventures adds a mobile-first communications asset to a portfolio backed by a fundraise targeting roughly $1B.
- SMB buyers choosing between legacy phone systems and app-based lines gain a better-capitalized challenger at the moment of purchase.
Second-order effects
- Cloud-voice competitors like Ringover face pressure to match OpenPhone's mobile-first team-number model, accelerating their own fundraising and product bundling of voice, video, messaging, and SMS.
- The same playbook — putting a workplace function on employees' personal phones instead of fixed infrastructure — draws parallel capital into adjacent categories, as seen when Openpath followed its earlier security-credential rounds with a $36M Series C.
Third-order effects
- If the funding pattern holds, small-business telephony structurally shifts from carrier-provisioned desk lines and hardware PBXs to subscription software where the smartphone is the endpoint and the number is a shared team asset.
- Venture capital increasingly prices SMB communications as a winner-take-most SaaS category, concentrating later-stage money (Tiger Global's entry into OpenPhone's B round being the marker) behind the early movers rather than distributing it across incumbents.
The trend: Small-business phone systems are being rebuilt as mobile-first SaaS, with each funding round — Series A here, Tiger Global's Series B later — validating the shared-number model over legacy PBX hardware.
