Volt Harbor raises $2M seed to commercialise modular, software-defined battery storage

Try Dealroom →, an Ann Arbor-based startup spun out of the University of Michigan, has closed a $2M seed round led by MFV PartnersDealroom has a profile for this one. Try Dealroom →. The company is commercialising its patented MAC-BESS™ platform — a modular, software-defined energy storage system that integrates battery storage, power electronics, and on-board computing into a single unit.
The technology borrows from computer networking architecture, using software to coordinate battery modules from different manufacturers and chemistries in real time. It can be configured for new battery cells in data centre deployments or for second-life EV batteries in cost-sensitive grid and industrial applications.
Volt Harbor holds six patents licensed from the University of Michigan. Its co-founder and chief executive officer, Dr. Al-Thaddeus Avestruz, is a former professor there.
Why now? Two forces are converging. Grid-scale storage demand is surging as AI-driven data centre construction collides with aging utility infrastructure. At the same time, millions of EV batteries are nearing the end of their automotive life, creating a growing supply of cheaper cells that need a second home.
"Volt Harbor's platform is well positioned to put them back to work at a cost point new-build systems can't match," said Karthee Madasamy, managing partner of MFV Partners.
The conventional data centre power stack — backup power, grid-tie capability, switchgear, uninterruptible power supply — requires sourcing from multiple vendors, each with its own lead times and integration burden. Volt Harbor aims to collapse those layers into one modular system.
What could go wrong? A $2M seed round is modest given the capital intensity of energy hardware. Scaling from pilot to commercial deployment will likely require significant follow-on funding. The company also faces competition from established battery storage players with deeper pockets and existing customer relationships.
Second-life battery supply chains remain unproven at scale, and questions around warranty, performance degradation, and safety standards for repurposed EV cells could slow adoption.
The signal: MFV Partners, an investment fund leading this round, is backing a thesis that software-defined architectures can disrupt the traditionally hardware-heavy energy storage market. With Volt Harbor still at the early growth stage according to Dealroom, the $2M seed is a first step toward proving that a networking-inspired approach to battery management can compete with incumbent BESS providers — at a moment when data centre power constraints are turning energy storage from a grid add-on into core infrastructure.
