Founded in 2023 by Ahmed Nasser and Ahmed Omar, Sully.ai has 49 employees and serves healthcare providers globally with AI agents that autonomously execute multi-step clinical and administrative processes without requiring physician or staff intervention. Sully.ai's AutonomousOS architecture positions the platform beyond single-task AI scribing tools: most AI clinical documentation products (Nuance DAX, Abridge, Nabla) focus specifically on converting patient-physician conversations into structured clinical notes — reducing documentation time but leaving all other administrative tasks (prior auth, billing, scheduling) to manual workflows. Sully.ai's autonomous agent approach addresses the full administrative burden: AI agents that can autonomously navigate prior authorization portals (submitting clinical criteria documentation, responding to payer information requests, initiating appeals), verify insurance eligibility in real time, process prescription refill requests, and generate patient billing summaries — tasks that each require multiple steps across external systems. The ambient AI scribing (listening to patient encounters through the physician's device microphone, understanding clinical context, and generating structured notes in the physician's preferred EHR format) reduces the documentation burden that has driven physician burnout and early retirement. In 2025, Sully.ai competes in the AI clinical documentation, healthcare workflow automation, and ambient AI scribing market with Nuance DAX (Microsoft-owned, NASDAQ: MSFT, dominant AI ambient scribing deployed at 500+ health systems), Abridge (AI clinical documentation, $150M raised at $850M valuation), and Nabla (AI scribing for physicians, $52M raised) for health system AI workflow automation contracts. The healthcare administrative burden ($390B+ wasted annually in the US on administrative complexity) represents the most actionable cost reduction target for AI in healthcare — autonomous AI agents that can execute prior auth submissions, insurance verifications, and care coordination tasks provide measurable ROI that justifies health system procurement above the documentation-only AI scribes. Sequoia Scout Fund and Y Combinator backing position Sully.ai in the enterprise healthcare AI investor community for future growth rounds. The 2025 strategy focuses on scaling enterprise health system deployments, expanding the prior authorization automation for the highest-burden specialties (oncology, neurology, orthopedics), and building the revenue cycle management AI for automated charge capture and denial management. ## Frequently Asked Questions ### What is Sully.ai?
