Vivian Health, a healthcare staffing platform based in San Francisco, appointed Adam Greenberg as CFO and Ved Sinha as chief product officer.

Greenberg joins Vivian Health from Roofstock, a digital marketplace for real estate investors. Prior to that, Greenberg served as CFO at Great Jones, a technology-enabled property management business, where he co-led the sale of Great Jones to Roofstock in 2021. Greenberg has held several finance and strategy leadership roles at both early-stage companies and household consumer brands over the last 12 years.

Sinha comes to Vivian Health with more than 20 years of experience in product management and product innovation. He will spearhead the company’s product and marketplace solutions strategy in his new role. Sinha most recently served as VP of product management at Robert Half International Inc., where he was a change agent for digital transformation. Prior to that, Sinha held executive roles at Edmodo and Upwork.

“Adam and Ved each bring deep experience across a diverse mix of digital companies and business models — including subscription and marketplace businesses — and they both have a track record of harnessing innovation to disrupt the status quo and go after big opportunities,” Vivian Health founder and CEO Parth Bhakta said.

Vivian Health, an IAC company, was founded in 2017. It is used by more than one million clinicians across all 50 states to look for permanent roles, per-diem shifts, local contracts, and travel positions.
