AI tools built by Mumbai engineer now protect supply chains at major US hospitals
Reuben Mathew Philip's software runs daily at 10+ major American hospital systems, including Ochsner Health, Geisinger, Yale New Haven Health, and Texas Medical Centre. The systems collectively treat millions of patients each year and rely on his company's tools to manage their medical supply chains.
Philip, who studied computer engineering at Don Bosco Institute of Technology in Mumbai before earning a master's degree from Northeastern University, arrived in healthcare by accident. A job at Boston Children's Hospital after graduation showed him a problem worth solving.
"I walked into a world where billion-dollar hospital systems were still tracking supply disruptions on spreadsheets," Philip said. "Nurses were leaving operating rooms to hunt for supplies. Contracts worth millions were being mispaid because nobody had automated the reconciliation process."
From one hospital to an industry platform
At Boston Children's, Philip built automation scripts that eliminated 53 hours of manual work per week for his team. He cut the hospital's billing exception rate by 20 percent and created a COVID expense tracking tool that leadership used to claim federal reimbursements. Several tools remain in use today.
After working on logistics automation at Amazon, Philip joined Clarium Health as its sixth employee and first data engineer in 2021. The startup had zero paying customers. Philip saw the chance to turn what he'd built for one hospital into a platform serving the entire industry.
Clarium has since raised more than $43 million from investors including General Catalyst, Northzone, AlleyCorp, and Kaiser Permanente Ventures. Philip moved into product leadership because of his deep knowledge of hospital supply chain operations.
Two products changing hospital operations
Philip led development of Disruption Monitor, which uses AI to aggregate data from hospitals, distributors, and medical device vendors. The system detects potential supply shortages before they affect patient care and recommends substitute items based on data shared across Clarium's customer network.
His second product, Card Optimizer, addresses waste in surgical operations. It analyzes hospital electronic medical records to identify inconsistencies in supply lists for procedures, then recommends standardization. Hospitals reduce waste and costs without changing clinical outcomes.
Under Philip's leadership, Clarium grew from zero customers to 10+ major health systems with zero customer churn.
Recognition in the field
In November 2025, the Bellwether League Foundation gave Philip its Future Famer Award, recognizing early-career leaders likely to make lasting contributions to healthcare supply chain management. The 2025 class included three recipients-Philip was the only one from a technology company.
He chairs the Young Professionals Advisory Council of AHRMM, the Association for Health Care Resource and Materials Management, and sits on its Education Committee. He reviews conference abstracts and speaks regularly at major US healthcare conferences.
Why this matters for managers
American hospitals spend hundreds of billions annually on medical supplies yet lack basic visibility into their own supply chains. The COVID-19 pandemic exposed how fragile those systems were when hospitals scrambled for protective equipment, ventilators, and medications.
Philip's work demonstrates how AI Agents & Automation can reduce manual work and prevent operational failures. For operations and supply chain managers, his approach-using data to anticipate problems rather than react to them-offers a practical model for improvement.
"Every piece of technology we build is connected to a patient outcome somewhere down the line," Philip said. "That's what keeps me going."
