About Us

Propel LLC is  a product innovation company focused on the development, sales, and marketing of innovative textile driven technologies.  Our primary markets are the US Military and Fire Service.  We are  problem solvers and solution finders.  We are avid listeners with a solid understanding of the science and nuances required in these markets.

Propel has received US Army R&D contracts  to develop textile technology solutions that have transitioned to acquisition. We were competitively awarded two Small Business Innovation Research (SBIR) Contracts by the US Navy, for Stitchless Seam Engineering (Phases I, II and III contracts) and Advanced Wireless Textiles (currently in Phase II).   Propel also consults for many globally recognized companies, with current and past clients including Globe Manufacturing LLC, Patagonia Inc., Cascade Designs, Aspen Aerogels, Miltech, SSM Industries, Mustang Survival, and Sheep Venture Company.

Our knowledge and networking skills offer our clients exclusive and unique resources.  We are not tied to a single technology - instead  we work  back from the problem in order  to develop collaboratively across companies and industries to develop the best solution for the user.  We are an adjunct to our clients, both government and commercial, taking on the difficult & innovative tasks essential to the success of each project.
