On the heels of an FBI raid of its offices in San Francisco, buzzy health startup uBiome is under investigation.

The company, which has raised $105 million and achieved a $600 million valuation, is reportedly being probed for issues related to how it billed for its tests, which were geared at highlighting the role the microbiome plays in human health.

UBiome portrayed its tests as free to patients and claimed insurance companies would foot the bill. In reality, customers were sometimes saddled with thousands of dollars of bills when their insurance declined to pay. Interviews that Business Insider previously conducted with several former uBiome employees suggest that the company may have cut corners on its science as well.

Now, additional reporting by Business Insider reveals that uBiome CEOs and cofounders Jessica Richman and Zachary Apte may have tried to conceal personal details, including their relationship and Richman's true age. Richman and Apte were placed on leave from the CEO role after the FBI raid.

Richman repeatedly presented herself as years younger than she actually was, in an apparent effort to be included in articles showcasing young founders.

Apte and Richman lived together in at least two states, according to public documents viewed by Business Insider. The two are in a romantic relationship, according to six former uBiome employees. The people asked not to be identified because they signed agreements not to reveal company information publicly.

One former employee said the relationship was widely known at uBiome, but that employees were discouraged from discussing it.

"It was an open secret at the company," a former uBiome employee told Business Insider. "Everyone knew, but we weren't allowed to talk about it."

As for her age, voting records and a personal document seen by Business Insider show that Richman is now 45.

In one instance in 2014, Richman told a Business Insider reporter that she was "under 30" but declined to provide her specific age. As a result, she was included in a list titled "The 30 most important women under 30 in tech." At the time, she was 40.

The following year, when Richman was 41, she was included on a CNN list highlighting innovative companies led by founders under age 40.

In 2018, Richman told a different Business Insider reporter that she was "under 40" and again declined to give her age. It earned her a spot on another list: "Meet the 30 healthcare leaders under 40 who are using technology to shape the future of medicine." She was then 45.

Richman and Apte did not respond to requests for comment.

Separately, the Wall Street Journal reported this week that uBiome was using stock photos to illustrate customer testimonials on its website. The company removed the testimonials from its website after questions from the Journal, the newspaper said.
