Try Dealroom →, a San Jose-based fabless semiconductor startup, has closed a $4.35 million seed extension led by Band of AngelsDealroom has a profile for this one. Try Dealroom →. The round brings the company's total funding to $10 million, comprising $7.25 million in seed financing and the rest in non-dilutive strategic development funding.

Try Dealroom →, Sand Hill AngelsDealroom has a profile for this one. Try Dealroom →, and Castle Fund joined the round. Returning strategic angels who backed earlier financings also invested additional capital alongside the new institutional investors.

What's the endgame? Overlord Labs builds battery intelligence directly into silicon through its Silicon × Algorithm Architecture. Its flagship GENESIS chip targets single-cell systems for smart glasses, wearables, hearables, and other edge AI devices, where rising compute demands strain battery and form-factor limits.

Why now? The financing lands as the company moves from tape-out to product validation, following the bring-up of its GENESIS chip. It will use the capital to complete validation and qualification, support customer sampling and Tier-1 OEM engagements, and build production infrastructure, targeting volume production in the first half of 2027.

Chief executive officer and co-founder Richard Nicholson said the company started because "battery management architectures were no longer keeping pace with the devices they power." He added that Overlord now has "working silicon, active customer engagement and an investor syndicate" ready to move GENESIS toward production.

The signal: The raise sits in the top 10% of all-time seed rounds in the energy sector by amount, a sign of investor appetite as compute shifts to the edge. As battery-powered devices demand more power efficiency and runtime, startups reworking fixed-function battery management for intelligent hardware are drawing fresh capital.
