Our Story


Modern flow cytometry originated in the late 1960s in the Herzenberg Laboratory at Stanford University, and as the utility and power of cytometers evolved into the 1990s, the need arose for a more powerful and user-friendly analysis and display program. FlowJo® was conceived in the laboratory to address this need and easily analyze flow cytometry data and was primarily written by Mario Roederer and Adam Treister, based on concepts developed with David Parks, Martin Bigos, and Wayne Moore.  

Our founders collaborated on the first prototypes for FlowJo® – Mario worked as a post-doctoral fellow in the Herzenberg lab and drove the evolution of the multicolor flow cytometry, and Adam served as a scientific programmer for the lab in 1995, as the analysis requirements of the multi-parametric data being gathered at Stanford had outgrown the power of any commercial software application.  The first version of FlowJo® was born as the next generation of the DESK software which was being used for analysis; Mario and Adam licensed the technology from Stanford and in 1997, FlowJo™ Version 2 was released commercially as a Macintosh-only application.


The company was moved from San Carlos, CA to Ashland, Oregon in 2003, simultaneous with an explosive growth in flow cytometry applications.  The Mac platform culminated with FlowJo® Version 9, originally released in 2010 with development still ongoing.  In 2012, we released Version 10, our first fully cross-compatible version.  We are proud to call Oregon home, and our 10,000 square foot headquarters is nestled at the base of two mountain ranges, in between Portland and San Francisco in Southern Oregon. 


Since 1997, tens of thousands of scientists worldwide have been trained in the use of FlowJo®, and an incredible user loyalty has been cultivated through personalized service and rapid software evolution.  We are deeply indebted to our customers for their support, advice, and feedback and the most important question we can ask is “How can we help?”  

Over the past three years, we have built significant functionality into both FlowJo® Version 9 and Version 10, including a suite of discovery tools, opening the architecture for third-party developers, spectral compensation, and a thousands of improvements to user experience.  We are committed to producing the best applications in life science because that is our obligation to our customers and to science.  

To meet this obligation, we are expanding the number of solutions, each a different answer to our question - “How can we help?”  FlowJo® continues to receive upgrades in functionality,  algorithms, and user experience; SeqGeq™ will be an application helping the new field of single cell sequencing and existing studies in gene expression drive insight from data; and FlowJo Envoy will revolutionize communication and collaboration in the life science laboratory.
