Function, a whole-body health company, announced it secured $298 million in an oversubscribed Series B round, boosting its valuation to $2.5 billion.
Redpoint Ventures participated in the round, with participation from numerous investors, including a16z, Roku founder Anthony Wood, WNBA's Breanna Stewart, NFL's Caleb Williams, WNBA's Diana Taurasi, Magic Johnson, Matt Damon, Menlo Ventures, Motley Fool Ventures, Samsung Next, Vanderbilt University and Zac Efron.
The Texas-based company, which last year raised $53 million in Series A funding, offers 100+ lab tests, including biomarkers that help monitor for early indicators of diseases. Based on the results, users obtain a clinician's summary of their overall health.
Through the company's platform, users can view their test results, access the clinician summary, and receive food and supplement recommendations.
The company also announced three new appointments: Dr. Daniel K. Sodickson as its new chief medical scientist and co-director of the company's new Medical Intelligence Lab; Dr. Tiffany Lester as Function's women's health medical director; and Neil Shah as its chief operating officer.
"We've spent decades waiting until people are sick to act," Dr. Sodickson said in a statement. "Function changes that. Medical Intelligence connects important signals — from blood to imaging to wearables — creating a continuously learning model of your health. It's not AI replacing doctors; it's clinical expertise amplified by intelligent systems that never stop learning."
Nest Health, a platform for women and families on Medicaid that provides access to medical, behavioral and social care, announced the close of a $22.5 million Series A round of funding.
Investors included Socium Ventures, Amboy Street Ventures, Impact America Fund, Hopelab, University Growth Fund and Luminary Impact Fund.
Socium Ventures will join the Nest Health board of directors.
The company will use the funds to expand its clinical products using AI, and to expand its reach in the states where it is currently offered and in new geographies through existing and new payer partnerships.
"Amboy Street Ventures invests in companies that fundamentally expand access to care for women and families. Nest's model succeeds because it delivers comprehensive medical, behavioral, and social care directly into the home – where it's most needed and most effective," Carli Sapir at Amboy Street Ventures said in a statement.
"What the team has built is not only clinically rigorous, but operationally scalable in a Medicaid environment that rarely rewards innovation. We're proud to support Nest as they enter this next phase of growth."
Revian, which offers light therapy for hair growth, has secured $13 million in equity and growth debt funding from tech investment firm Flashpoint.
The company's FDA-cleared device uses red light technology to stimulate nitric oxide production, which it says reduces dihydrotestosterone (DHT) levels and scalp inflammation and enhances scalp microcirculation.
The company says its device, therefore, "addresses three well-established biological drivers of hair follicle miniaturization and progressive hair loss."
The company will use the funds to scale commercially, expand its product line and launch internationally.
"This financing enables us to meet accelerating demand from medical practices nationwide while laying the foundation for our global expansion," John Oakley, CEO of Revian, said in a statement.
"We've demonstrated strong clinical results and a scalable physician-led model. Flashpoint's partnership allows us to extend that success to new markets and patients worldwide."
