Par8o has secured a $3 million convertible note provided by United Healthcare, a division of one of the biggest health insurance providers in the U.S. The funds are raised as a run-up to the Series B round, which is expected to bring anywhere between $10 and $20 million to the company.

par8o develops what it calls the Healthcare Operating System which allows organizations to optimize their networks of providers and other resources to deliver quality care by applying one of the most powerful and proven principles in economics – Pareto Optimization. This approach, and the EMR-agnostic technologies par8o has developed to implement it, are well-suited to healthcare as they can achieve continuous efficiency improvements while balancing the needs of all parties.

The company’s clients include the largest employer in the State of Nevada – MGM Resorts, and several pre-eminent academic medical centers, such as Harvard Medical School affiliated hospitals in Boston and facilities that are part of the Mount Sinai Health System in New York.

In January, par8o’s raised $10.5 million Series A round from Atlas Venture, Founder Collective, CHV Capital and other investors.
