What Nines does
Nines is a privately held, for-profit radiology practice based in Palo Alto, California, founded in 2017. The company positions itself as a "first-of-its-kind radiology practice" that integrates radiologists, data scientists, and engineers into a single operating model, suggesting a hybrid diagnostic-services and technology-enabled workflow. Disclosed headcount is in the 11-50 employee band. No detailed product portfolio, technology stack, regulatory clearances, or specific service offerings are documented in the available source material, which limits further technical characterization of the platform or clinical workflow.
The company has raised approximately $34.5 million across three disclosed venture funding events between 2017 and 2020. Investors include Accel (lead in the 2017 round and co-lead in the 2019 Series B), 8VC (co-lead of the 2019 Series B), Gaingels, Bossa Invest, Sand Hill Angels, and Sleeping Bear Capital. Disclosed leadership includes Max Ochoa as General Counsel and CFO, Paul Twohey as VP of Engineering, and Andrew Ring as Head of Clinical Engineering, which reinforces the hybrid clinical-engineering operating model. No information on pricing, revenue model, customer segmentation, partnerships, geographic footprint, or post-2020 financing is provided in the input.
The company remains privately held with no public IPO disclosed, and the absence of detailed product, customer, and revenue information in the source material constrains definitive characterization of the business model and go-to-market approach.
