Accuri Cytometers Completes $13 Million Series C Financing

New Funds will Support Expanded Commercialization of the Revolutionary Accuri C6 Flow Cytometer(R) System

ANN ARBOR, Mich., Accuri Cytometers Inc., a life sciences company developing revolutionary bench-top flow cytometer systems, announced the completion of a $13 million Series C financing led by Fidelity Biosciences and Flagship Ventures. Current investors including Baird Venture Partners and Arboretum Ventures also participated in the financing. Accuri will use the proceeds from the Series C financing primarily to expand its commercialization activities for the Accuri C6 Flow Cytometer System. Bahaa Fam, Venture Partner, Fidelity Biosciences and Harry Wilcox, Partner, Flagship Ventures, will join the company’s Board of Directors.

Explicitly designed for routine use by biomedical researchers in their own labs, Accuri’s flow cytometer system is a full featured bench-top cell analysis system that provides capabilities similar to industry-leading flow cytometers in a more user-friendly format and at a fraction of the cost.

“This successful Series C financing led by Fidelity Biosciences and Flagship Ventures reflects the progress we have achieved in developing and commercializing our breakthrough flow cytometer system,” said Jennifer Baird, CEO of Accuri. “Our strong initial acceptance in the marketplace is now ramping up and these new resources will enable us to further expand the reach of our marketing and sales efforts. We are pleased that our existing venture investors all participated in this round, and we look forward to the contributions of our new Board members.”

Accuri created its revolutionary C6 system with input from hundreds of researchers who use flow cytometry, including many whose research has been fettered by resource constraints in their facilities. The company teamed with Menlo Innovations, which brought its unique, award-winning methods to the development of the Accuri system’s easy-to-use analysis software, a critical component of the approach. Accuri’s innovations, coupled with its state of the art components, result in a cytometer that is powerful, robust, compact and affordable, at less than one-third the cost of the market leader.

“We are enthusiastic about our investment in Accuri,” said Bahaa Fam, Venture Partner, Fidelity Biosciences. “By making flow cytometry technology more affordable, accessible and usable, Accuri’s high performance systems have the potential to accelerate and broaden the scope of biomedical research. We welcome this opportunity to help the company progress to the next level.”

“Flow cytometry is an essential tool in biomedical research, and Accuri’s outstanding team has responded to the need for accessible, affordable easy-to- use systems by completely re-inventing the flow cytometer from the ground up,” said Harry Wilcox, Partner at Flagship Ventures. “The Accuri Flow Cytometer System is already gaining traction among researchers, and we are very optimistic about the future potential of this promising company.”

“As Accuri continues to commercialize its revolutionary technology, we are very pleased to welcome Fidelity and Flagship representatives as new investors and as Board members,” said Pete Shagory, Accuri Chairman and a Partner at Baird Venture Partners. “Their expertise in the research tools space will be especially valuable as Accuri expands its efforts to effectively grow the business.”
