Sumeet Singh

President & Senior Consultant

Sumeet started his career at a regional drug wholesaler as head of special projects, including state licensing and software ERP implementation. He moved on to take a leadership role at a regional, full-line pharmaceutical distributor with responsibilities spanning purchasing, sales, operations and finance. With the 2015 implementation of the DSCSA, Sumeet gained expertise in all aspects of the Federal Law as he led the creation and implementation of new processes and systems. Sumeet founded his first start-up in 2015: OpenRX, a described “Amazon” for pharmaceuticals, was sold to an operating private equity firm just 12 months after inception.

In late 2015 Mr. Singh founded Five Rivers RX. Drawing on the relationships and knowledge he cultivated at the helm of a distribution company, Sumeet is able to bring a unique “boots on the ground” understanding of the industry. With over 200 clients, spanning Fortune 500 companies and start-ups, across 15 different business models, Five Rivers RX has established itself as a “go-to” resource through the pharmaceutical supply chain.

Sumeet Singh has been published in trade publications including Pharmaceutical Commerce and has spoken at events including American Conference Institute Controlled Substances Summit, IQPC Pharmaceutical Traceability Forum and Chain76.
