Nik is seriously passionate about finding solutions to problems & this is where the idea behind SimpleFlow came alive. Nik has a background in Direct Marketing and managing sales operations for over 7 years within the solar space. Over the years, he’s learned that the key to running a successful organization is having the management team focus on the right of aspects of the business, specializing in what they’re good at & what they love to do. As a personal advocate for renewable energy & creating sustainability across the globe, Nik’s core focus is to create an organization that not only does well by the planet but also by its customers & employees.

Will’s love for the environment and desire to make a change in how the world generates and consumes electricity began in his high school geoscience class where he first learned of our society’s abusive and unsustainable treatment of the environment. Will’s intense interest in renewable energy began. He later attended the University of Denver where he studied Finance and Accounting. Working in private equity during college and managing a sales team at Cutco inspired Will to follow his dreams of entrepreneurship. After college, Will continued his journey west to San Francisco where he worked in sales at a logistics technology company called EasyPost. He saw the company grow from 30 employees to 200+ during his tenure. “Out of all of the renewable energy sectors, I gravitated to solar because it allows me to work on utility and commercial projects that make a big change but I am also able to work with individuals and make an impact on their daily lives.” - Will
