Ostro
Ostro (Veeva Ostro) is an AI-powered brand engagement platform for life sciences. Founded in 2019 as RxDefine and legally incorporated as Rise Healthcare Tech, Inc., the Miami-based, remote-first company turns a pharmaceutical brand's existing PRC/MLR-approved content into compliant, two-way conversational AI across web, email and SMS. Its products are Navigate (web engagement), Airmark (conversational email for HCPs), Prompt (SMS) and Tailor (brand-website intelligence), unified in September 2025 into a single digital experience. The platform is grounded exclusively in approved content and is designed not to generate novel responses, which is how it clears promotional-review requirements. Veeva Systems (NYSE: VEEV) acquired Ostro on 2026-03-10 for approximately $100M and runs it as an independent unit whose capabilities are being folded into Veeva Commercial Cloud. Ostro publishes no public developer program, API reference or machine-readable contract; its only machine-readable surface is an llms.txt served at its own website root.
Ostro is profiled on the APIs.io network. Tagged areas include Company, Life Sciences, Pharmaceuticals, Healthcare, and Artificial Intelligence.
Ostro’s developer surface includes engineering blog and 12 more developer resources.
