David Mansfield


David Mansfield has 10 years of experience in the fuel industry. He began his career with Indigo in government bids and sales. In this department he learned all facets of the industry from procurement, taxes, licenses, contracting, sales, and dispatch. After two years’ experience in government fuels he moved into commercial sales. His customer base consisted of regional petroleum companies, larger convenience store chains, and national trucking companies.

Following his five years as an account executive, David advanced to Director of Sales. He was responsible for overseeing the entire sales team and implementing a new go-to-market plan and operating system.

Looking to the future, David, along with John Mansfield, decided to examine alternative energy sources with a focus in solar energy. Over the last eighteen months David has researched prospects of the solar industry and begun to sell to a targeted customer base. In the first year he completed a 100kW system on a distribution center in Norcross, GA. Since then he has continued to focus on commercial and industrial companies.

As of November 2019, he has assumed the new role as President of Indigo. In this position he will manage both the fuel and solar sales forces.

For the six plus years that I’ve been with Indigo Energy my single greatest pride comes from the relationships I’ve built and maintained with customers and vendors. I’ve relentlessly practiced a customer-first mentality in everything I do. It is one of the few things I can control on a day-to-day basis and is the cornerstone for every successful relationship I’ve been a part of.

I work closely with government as well as commercial accounts. I have extensive logistics capabilities and can negotiate the best rate for my customers, from generator fills to bulk storage.

I am currently leading business development for Indigo Solar in order to reduce carbon emissions while also reducing tax obligations and operating costs for clients.
