It works with more than 55 leading health systems and payers, has processed billions of dollars in patient payments, and reached a $3.2 billion valuation after a 2021 Series D.
Florian Otto
Florian Otto is the co-founder and CEO of Cedar, a New York healthcare financial technology company that reworks how patients understand and pay their medical bills. A former physician trained in Germany, Otto moved from medicine into consulting at McKinsey, built a daily-deals business in Brazil that became Groupon Brazil, and ran commercial sales at ZocDoc before starting Cedar in 2016. He built the company around a simple frustration - a confusing hospital bill his fiancee received - and a bigger question: why can't healthcare billing feel as clear as buying from Amazon or Expedia? Cedar has since raised roughly $400M+ and works with hospitals and health systems across the United States.
Collectly

Founded in 2017 and a Y Combinator graduate, Collectly says it serves 3,000+ healthcare facilities and has processed over $1 billion in patient payments. In 2025 it launched Billie, a 24/7 AI agent that answers patient billing questions and takes action across voice, chat, text and email.
