I would like to express my respect and appreciation for Jim Sadler and Tribulus Design. He helped Oakley with design support for the better part of a decade. We worked closely in establishing creative direction, as well as in critiques & reviews of designs for dozens of products. He has always shown a strong dedication to projects, demonstrated a great ability to be creative and bring unique designs to the table, provided a good example for others on the team, and has contributed notably to the profitability of the category and brand. I would happily work with him again, and strongly recommend Jim and Tribulus Design for any important project.

Colin Baden, CEO of Oakley

I have collaborated with Tribulus Design on a number of projects and continue to be impressed by his design eye and development capabilities and experience. Jim Sadler is one of those creative guys that sees the world differently and is continuously coming up with fresh design approaches that work! His involvement on Bitybean’s UltraCompact Baby carrier was critical to our product success and also helped us win the coveted JPMA Innovation Award. I would recommend Tribulus for any consumer product design project.

We (Swagman) started working with Tribulus Design in March of 2014 and were originally going to utilize them for their textile expertise but were surprised to know they also have a strong and unique background in industrial and mechanical design and has completed two very compelling projects and many more planned for the balance of 2014 and into 2015. Tribulus's ease of doing business and their fresh ideas and approach were exactly what Swagman was seeking.

Perry Grago, President Swagman

Jim Sadler's attention to detail and understanding of the development process from concept-to-delivery at retail is unparalleled in the product sphere of life.

Stephen Cleary, Vice President Product, Licensing and Marketing at M-Edge Accessories

Jim Sadler & Tribulus Design was introduced to me as a potential designer for a new product we were developing. His knowledge of the production process, access to manufacturing and cutting edge design skills, helped our company go from concept to market faster than we could have done on our own. The biggest value for us was the ease of doing business, personal attention, and accessibility. These factors, along with Tribulus' quality of work, make us proud to call them a partner in our company.
