What Blackwell Security does
Blackwell Security was a healthcare-focused cybersecurity company founded in May 2024 and headquartered in Ann Arbor, Michigan. The company developed and operated a Managed Healthcare Extended Detection and Response (MHXDR) platform — also referenced as the Pulse XDR platform — designed to deliver threat detection and automated response capabilities tailored to the operational and clinical realities of healthcare systems, including protection of patient data and clinical environments. Its target market was U.S. healthcare organizations, accessed primarily through enterprise sales and strategic partnerships with health systems and General Catalyst's Health Assurance Network.
The company operated as a managed security services provider with a subscription-based, recurring revenue model centered on the MHXDR offering. Its go-to-motion combined direct enterprise sales to healthcare buyers with partnership-driven distribution, leveraging relationships with lead investors General Catalyst and Rally Ventures to access the healthcare sector. The company's proprietary positioning was rooted in vertical specialization — packaging XDR capabilities around healthcare-specific threat patterns and workflows rather than competing as a horizontal XDR vendor. With 11–50 employees at acquisition, Blackwell remained a small, pre-scale operator.
Blackwell Security raised a $13 million funding round in May 2024 co-led by General Catalyst and Rally Ventures, appointed Geyer Jones as its first CEO in July 2024, and was acquired by Ostra Security in August 2025. Following the acquisition, Blackwell's XDR platform (Pulse) was integrated into Ostra's broader managed security services portfolio, extending Ostra's healthcare cybersecurity capabilities. The company had no public revenue disclosures prior to acquisition.
