This predictive capability allows medicinal chemists to prioritize viable molecules early, cutting down on trial-and-error experimentation and costly delays.
The company’s innovation extends beyond algorithms. Through a pre-competitive data consortium, Inductive Bio enables pharma companies to securely contribute anonymized data, enhancing the accuracy of its AI models. Its flagship model, Beacon-1, recently outperformed 38 rivals in the Polaris ADMET challenge, including efforts from leading academic and biotech labs.
Axle Health
CEO: Adam Stansell
As demand for at-home care surged, Adam Stansell saw a critical bottleneck: healthcare lacked the kind of real-time logistics backbone that had transformed industries like food delivery and freight. Drawing from his experience launching Uber Eats and optimizing trucking fleets at Motive, Stansell co-founded Axle Health in 2020 with Connor Hailey to solve one of healthcare’s most complex problems efficiently delivering care at home.
This May, Axle Health announced a $10 million Series A round led by F-Prime Capital, with backing from Y Combinator, Pear VC, and Lightbank. The funding marks a pivotal moment as Axle transitions from a services business into the infrastructure layer powering home health logistics.
Originally operating as a tech-enabled care provider, Axle made a bold pivot in 2023. Instead of delivering care itself, it began licensing its logistics platform to traditional home health agencies and hospital systems. That platform now handles clinician scheduling, route optimization, and patient engagement all driven by AI.The month of May witnessed notable venture capital activity across the AI sector, with companies securing significant funding rounds to fuel their growth and innovation initiatives. The month’s funding landscape demonstrated continued investor confidence in AI-driven solutions and specialized technology platforms addressing industry-specific challenges.
