Doug Lee

Doug Lee is Co-Founder and Managing Partner of Flathead Forge, a Houston-based fund investing in the infrastructure of the Industrial Supercycle. Flathead Forge partners with founders solving the physical constraints on the next industrial era: energy, water, critical resources, and advanced manufacturing. Doug's view is that energy is the prime supercycle, and it is driving secondary supercycles in water, critical minerals, and gas. The fund backs the technologies those markets cannot grow without.

He is a founder, operator, investor, inventor, and mentor with thirty years in industrial water, gas, and energy technology. He founded GLR Solutions, a produced-water treatment company whose technologies are now standard across the global industry. That business operates today as Enerflex Water, and Doug led it as President and CEO through its years of rapid global growth. He went on to senior roles at both Veolia and Suez, where he led their oil and gas technology portfolio.

With his brother Dave, Doug built Inception Oilfield Technologies, an international equipment and OEM channel business with offices in Houston, Calgary, Oman, and Mexico. The two then acquired, rebuilt, and sold Azoto Energy, an industrial gas services company. That exit seeded Flathead Forge. Doug has also managed his family office, Flathead Equity Partners, since 2009.

At Flathead Forge, Doug forms companies as well as funding them, and he works with founders on the part of company building he knows best: turning industrial technology into a first commercial sale, a repeatable channel, and an exit. Recent formations and portfolio companies include Pivotal Fluid Solutions, Resin8.ai, Prodigy, and Oxide Energy. He also mentors founders in the Energy stream at CDL-Rockies and CDL-Texas.

He is a named inventor on more than 15 patents and holds an M.Sc. from Louisiana State University. He splits his time between Houston and Montana.
