Based in Chandler, Arizona, Raintree is an electronic health record and practice‑management platform focused on rehabilitation and physical therapy organizations. In a move that expands its AI portfolio, the Serent‑Capital‑backed company has acquired Heightened AI voice technology for healthcare. Spike, founded in 2022, has attracted backing from Practica Capital, The Venture City, Plug & Play, Geek Ventures, CEAS Investments, and NVIDIA Inception.

The deal, for which no financial terms were disclosed, signals Raintree’s intent to embed advanced voice‑assistant capabilities into its EHR ecosystem. Spike’s technology enables clinicians to interact with patient records, schedule appointments and retrieve clinical data through natural‑language voice commands, thereby improving workflow efficiency. By integrating these features, Raintree will offer a more seamless, AI‑powered experience to therapists and rehab centers.

The acquisition also positions Raintree to compete more aggressively in the rapidly growing healthcare AI market, where firms are increasingly leveraging voice and agentic AI to streamline care delivery. For healthcare providers seeking a unified, AI‑enhanced platform, the merger presents a compelling upgrade that could translate into higher productivity and better patient outcomes.
