Indian American's AI Health Startup Hits $2.5B Value

Patil, who dropped out of Harvard's master's program in design engineering to launch the company, said she was inspired by her own diagnoses of PCOS and prediabetes. She wanted a system that could flag warning signs before they became serious problems.

Function's membership includes at-home blood collection, full-body MRI and CT imaging, and AI-powered analysis of results. The company says the $365 annual fee is a fraction of the roughly $15,000 cost of purchasing comparable tests independently.

Patil said the hardest part was convincing investors of the broader vision. She noted the company made acquisitions, including imaging and home blood draw services, to scale quickly rather than building everything in-house.

Looking ahead, Patil said Function aims to reach 8 billion people, with AI playing a key role. She described the current phase as 'act two,' following the foundational lab work, and expressed excitement about a future where people can detect problems early and take action.
