Weave sells a software platform to small and medium-sized healthcare practices that consolidates patient communications, scheduling, payments, and practice analytics into a single system. The platform's foundation is a proprietary VoIP phone system, layered with appointment reminders, two-way texting, online scheduling, digital intake forms, insurance verification, review management, and an AI receptionist capable of booking appointments and handling inbound calls 24/7 without staff involvement. Weave serves nearly 40,000 locations across the U.S. and Canada, primarily in dental, optometry, veterinary, and specialty medical practices. Revenue comes from two streams: per-location subscriptions (the dominant stream, offered in tiered bundles) and transaction-based payments fees via Weave Payments, which processes in-office, text-to-pay, and online bill pay transactions. Growth is driven by new location additions, expansion of average revenue per location as customers adopt higher-tier bundles and add-ons, and growth in payments volume. Weave sells primarily through an inside sales team, supplemented by channel partners. Key growth vectors include expansion into specialty medical (which Weave estimates is more than twice the addressable size of its other three verticals combined), deeper penetration of payments across its installed base, and buildout of an omnichannel AI receptionist following the 2025 acquisition of TrueLark for $35M.
