Sean Casey is an experienced entrepreneur, technology executive, board member, and advisor. He is currently the Head of Product for divvyDOSE, an early-stage tech-enabled pharmacy, where he brings his technology and leadership skills to help scale the business. Sean’s life as an entrepreneur started in high school when he launched a web site for the local music scene in Chicago. In 2001 Sean went on to attend University of Illinois at Chicago for Computer Engineering and in his freshman year co-founded All Information Services (AIS), a boot-strapped technology consulting company serving small businesses. After 10 years of growing AIS Sean co-founded Shiftgig, a labor marketplace with over $50MM in venture backing. He served as CTO and head of analytics at Shiftgig and was responsible for building a team and defining the direction of the tech platform and product road map. Sean left Shiftgig in 2017 to pursue a life long desire to live in a new city and to get involved in early stage startups again. Over the years he and his companies have earned various awards and recognition but he’s most proud of the positive impact his companies have made on people’s lives. Sean recently relocated to Nashville with his wife and two golden retrievers.
