The Bitcoin Miner That Decided It Was Really an Energy Company
MARA runs roughly 1.9 gigawatts of computing across four continents, holds more than 50,000 bitcoin, and now wants to sell you the cooling tanks and energy software behind it all.
M2X Energy Inc.
M2X Energy builds modular, trailer-mounted gas-to-liquids systems that convert wasted methane - the gas flared at oil wells, landfills, and digesters - into low-carbon methanol. Founded in 2020 and headquartered in Rockledge, Florida, the company replaces giant fixed chemical plants with mass-manufactured 'chemical plants on wheels' that drive up to a stranded gas source, connect, and run. After proving the model on flare gas at a Chord Energy well in the Bakken, M2X raised a $40M Series B in 2024 to build its first commercial fleet.
Josh Browne
Josh Browne is the co-founder and CEO of M2X Energy, a Rockledge, Florida climate-tech company that converts wasted methane from flares and landfills into low-carbon methanol using modular, truck-transportable gas-to-liquids systems built around repurposed internal-combustion engines. M2X grew out of his Columbia PhD dissertation, was founded in 2020 by Breakthrough Energy Ventures, and raised a $40 million Series B in 2024 (about $62.5 million total). Before M2X, Browne founded a data-science firm, Rho AI, that was acquired by General Motors. He started as the company's CTO and now runs it as CEO.
