Amperesand

We raised an $80M Series A. Thank you to our new investors, partners, and stellar team for supporting this powerful milestone. Here's what's next: 🎯 Purpose - the time is now to upgrade our power infrastructure. Critical power users like AI datacenters need solutions to build ultra-dense compute at scales never before seen. The grid needs to keep up with a new era of demand growth. Amperesand's Medium Voltage SST is the answer. 💪 People - Amperesand continues to grow an exceptional global team of the best and brightest leaders in energy technology. We're aiming for 100 people by early next year across lively offices in Singapore, San Francisco, and Reno. 📈 Proof - the future of critical power infrastructure is here. We're bringing 30MW of SSTs into the real world with critical power customers. AI datacenters and the world's largest ports we will accelerate time to power with a radically compact, grid-friendly, and reliable power conversion solution. 🏭 Production - we're standing up advanced manufacturing in Reno, Nevada to build our SSTs at scale leveraging secure, short lead-time, and tariff optimized supply chains. Thank you to Walden Catalyst Ventures Temasek for leading this round to support our vision of unlocking the future of critical power growth with medium voltage SSTs. Thank you to new investors Industry Ventures, Acclimate Ventures, SG Growth Capital. Thank you to our steadfast supporters Xora Innovation, Material Impact, TDK Ventures, Foothill Ventures since the beginning in 2023. Thank you to Katie Fehrenbacher for covering our announcement!
