A few months ago, a close family member of mine needed a routine medical procedure. The care team was ready. The facility had an opening. But the entire process was put on hold while the office staff chased down a prior authorization from the insurance company. Days of back-and-forth. Hours of staff time. And in the meantime, unnecessary anxiety for my family.
Unfortunately, this is not an unusual story. It’s the reality of a system where a third of the healthcare workforce is dedicated to administrative tasks, costing over $450 billion annually. Endless phone calls, long hold times, and redundant processes eat up resources that should be directed toward patients.
That’s why we’re so excited about Prosper AI, which today announced a $5 million Seed round to bring voice AI agents purpose-built for healthcare to market. Emergence is proud to lead the round, alongside Y Combinator, CRV, and Company Ventures.

Prosper is working with industry leaders like a 30,000-employee billing company to transform their core operations. In speaking to customers, we consistently heard that voice AI is the biggest innovation in the healthcare revenue cycle management area since the EHR, and that Prosper’s product was the best in market. This customer love is driving rapid growth, as Prosper has more than quadrupled revenue since last quarter.
Prosper co-founders Xavier de Gracia and Josep Mingot met in Boston while studying at MIT and Harvard, and their backgrounds in call centers and regulated industries uniquely positioned them to build AI agents for healthcare’s most complex workflows.
When I think back to that delayed procedure, I can’t help but wonder how different the experience could have been if Prosper’s agents were already deployed. Faster authorizations. Less stress. More care delivered on time.
Healthcare should be about patients, not paperwork. That’s the future Prosper AI is building—and why we’re so proud to partner with them on the journey.
