Roy Johnston

Founder, Principal

Roy is the founder of Orange River Advisors, where he leads project teams, helping clients gain insight and seize opportunity within their business. Roy is consistently recognized for helping clients define a clear pathway to the next level in their business and then executing to achieve that goal.

As principal, his most recent project was helping a client acquire a company that took their business in a new direction and substantially increased their business value. The team built a new pitch deck, completed due diligence for the acquisition, helped with re-branding, and built new financial models to evaluate the opportunity.

Previously, Roy served as a director in the corporate venture capital arm of Waste Management, Inc., where he managed a portfolio in the smart-sensor, logistics, and materials reuse sectors. Prior to WM, he was general counsel to publicly-listed mezzanine debt fund. Roy is also co-founder of StartHereNow, the premiere startup weekend accelerator for women-led businesses.

Roy’s personal motto is “know thyself”. Outside of work, you can find Roy spending time with his wife and family, swinging a hammer (at the 29th Parallel Workshop), or exploring the next site on his bucket list goal of visiting all state and national parks in Texas.

Our Heritage

The Orange River is the longest river in South Africa, where Roy Johnston, founder of Orange River Advisors, grew up. It flows 1,367 miles from the peaks of the mountains of eastern South Africa, to the Atlantic Ocean. Like the Mississippi, it provides water to much of the country.

The name Orange River Advisors is a reflection of the strength and sustaining nature of rivers large and small around the world. We see a parallel between rivers and the best businesses and organizations. Both are persistent, flexible, life-giving, intricate, and vital to our world.
