Strategic Investor Network – Beyond top venture firms, Base Power’s backers include Lennar (homebuilding), Starwood (real estate), and university endowments like WashU. These strategic investors bring distribution channels, deployment partnerships, and institutional credibility 2. Hypergrowth Trajectory – The company grew 30% month-over-month, has thousands on its waitlist, and is already doing millions in monthly revenue. 3. Domestic Manufacturing – Base is building its first factory in downtown Austin, repurposing the old Austin American-Statesman printing press, with plans for a second plant already underway. 4. Grid Bottleneck & AI – Energy is now the key constraint for AI/data centers. Base’s distributed battery model offers faster, cheaper deployment than traditional interconnection queue. 5. Culture as Differentiator – Base Power embodies a “chop wood, carry water” culture, with IC-driven leadership, top-tier engineering hires from Tesla, SpaceX, Anduril, and a flat, hands-on team structure. 1.
