Matt Prusak, the former president of American Bitcoin, has taken on the role of chief financial officer at Giga Energy, a company focused on flexible, modular power solutions for Bitcoin mining. The move, announced this week, underscores a broader industry pivot toward adaptable energy infrastructure as miners grapple with rising costs and regulatory pressure.
From president to CFO
Prusak spent his tenure at American Bitcoin as president, overseeing operations at one of the larger mining firms. His jump to the CFO seat at Giga Energy marks a shift from operational leadership to financial stewardship — but in a company that sits at the intersection of power and mining. It's a career move that reflects how intertwined energy strategy and mining economics have become.
The timing isn't accidental. Mining margins have tightened this year, and firms are looking for ways to cut power costs without sacrificing uptime. Modular, flexible power solutions — the kind Giga Energy builds — let miners scale up or down quickly, or even sell power back to the grid when it's more profitable than hashing.
The modular power play
Giga Energy designs and deploys containerized power units that can be dropped into existing mining sites or paired with renewable sources. The idea is to avoid the long lead times and high capital costs of building permanent substations. Instead, miners can plug in a modular unit, run it for a season, and move it elsewhere if the economics shift.
That flexibility is becoming a competitive advantage. Several large mining operators have already started experimenting with mobile power setups, and the trend is expected to accelerate. Prusak's move into the CFO role at Giga Energy suggests the company is preparing for a growth phase — possibly raising capital or expanding its customer base.
The appointment signals that mining companies are prioritizing financial leadership with deep operational experience. Prusak knows the pain points of running a mining fleet — the power contracts, the curtailment risks, the maintenance headaches. Bringing that perspective to a power solutions firm could help Giga Energy tailor its products to what miners actually need.
It also highlights a shift in how the industry thinks about infrastructure. Instead of building for permanence, miners are starting to treat power as a modular resource — something that can be turned on, off, or relocated. That's a big change from the fixed-asset model that dominated the 2021-2025 boom.
It's not yet clear whether Giga Energy will announce new partnerships or projects under Prusak's financial leadership. The company has not disclosed its next steps. But the hire itself is a signal: the future of mining infrastructure may be less about concrete and more about containers.
