The founders are Steve Visuri and Karen Harrington who have over 40 years of experience in medical devices and diagnostics with senior leadership positions at Prodesse, Gen-Probe, and Hologic.  Initially we are focused on developing microbiota-based products to treat recurrent clostridium difficile (C. diff) infections.  In parallel, we are seeking to establish a CLIA Clinical Laboratory to perform complimentary diagnostic testing.  Future opportunities include next-generation therapeutics for treating a variety conditions related to gut dysbiosis and expansion of laboratory test menu.

FloraSeq is proud to be one of nine winners of a Wisconsin Innovation Award (www.wisconsininnovationawards.com). Out of 180+ nominees, the 35 finalists were whittled down over a couple rounds of submissions and judging, with awards being announced Aug 16th in UW-Madison’ Union Theater. We were honored to be part of this great event celebrating an impressive array of innovations coming out of WI. Story in Milwaukee Journal Sentinel featured a picture of our capsules.

We are excited to announce that we have received a seed-stage round of funding from BrightStar of Wisconsin (www.brightstarwi.org)!  This proof-of-principal funding will largely go towards pre-clinical studies of performance in patients suffering from recurrent C. diff and who would otherwise be candidates for traditional Fecal Microbiota Transplant. The data will be important in establishing that the freeze-dried capsules are effective in small scale studies and will support “fast-track” FDA regulatory filings



FloraSeq was chosen among nine finalists to present our business opportunity to an international panel of biotech professionals and venture investor judges at the first Healthcare Innovation Pitch event coordinated by the non-profit accelerator Bridge-to-Cures. The mission of the event was to strengthen regional partnerships and create a stronger startup hub within the healthcare sector.



FloraSeq has been selected to present at the Wisconsin Angel Network Investors Track during the 2015 Early Stage Symposium in Madison, WI.  The 2-day conference is designed to unlock Wisconsin’s entrepreneurial potential by bringing together entrepreneurs and investors, highlighting promising start-ups, and providing instruction and advice.



FloraSeq’s founders, Karen Harrington and Steve Visuri, have been selected to participate in the NSF-funded Innovation-Corps (I-Corps) program. Combining experience and guidance from established entrepreneurs with a targeted curriculum, the I-Corps program teaches participants to identify valuable product opportunities and offers entrepreneurship training critical to the success of early stage companies.
