About Stoecker Dean
Dean Stoecker is best known as the co-founder of Alteryx, the U.S.-based software company focused on analytics and data science. Public company filings state that he co-founded Alteryx in 1997, when it was originally called SRC, and later oversaw its rebranding to Alteryx in 2010. He served as Chief Executive Officer from March 1997 through October 2020, after which he moved into the role of Executive Chairman of the board. That long tenure makes him the central founder figure in the company’s history, spanning its early development, scaling phase, public listing, and later governance transition. ([fintel.io](https://fintel.io/doc/sec-alteryx-inc-1689923-10ka-2024-march-15-19797-2142?utm_source=openai)) Before founding Alteryx, Stoecker held commercial and strategic roles in the technology and information-services sectors. According to company disclosures, he worked as Director of Enterprise Solutions at Integration Technologies, Inc., served as Vice President of Sales at Strategic Mapping Inc., and held various sales and strategy roles at Donnelley Marketing Information Services, a division of Dun & Bradstreet. He also appears in public sources as having been associated with MVC Capital, where he was linked to venture and growth-stage investing activity. Taken together, these roles suggest a background rooted in go-to-market execution, enterprise solutions, and business development. ([fintel.io](https://fintel.io/doc/sec-alteryx-inc-1689923-10ka-2024-march-15-19797-2142?utm_source=openai)) His most notable achievement is building Alteryx into a recognized analytics platform and leading it through major milestones, including its 2017 IPO. Alteryx’s own communications describe him as a key driver of the company’s vision and growth, with an emphasis on empowering business users to prepare and analyze data more effectively. In governance terms, he also played an important continuity role on the board, helping guide executive transition and maintaining institutional knowledge at the company he founded. For SEO and executive-profile purposes, the most accurate summary is that Stoecker is an entrepreneur, founder, former CEO, and current Executive Chairman whose career is defined by software leadership, analytics innovation, and long-term strategic stewardship.
