Our Story

Since our founding in 2019, Castalune has been recognized by institutional leaders in technology innovation and the energy transition via financial awards, investment and commercial guidance.

Backed by the advisory of global energy companies managing over 300GW of capacity, Castalune has garnered more than $2 million in financial support from U.S. Department of Energy’s innovation organization (ARPA-E), Massachusetts Clean Energy Center (MassCEC) and DCU FinTech Innovation Center. In 2022, Castalune entered into a strategic partnership with 547 Energy, the global clean energy investment platform of Quantum Energy Partners.

Our Leadership

The Castalune team is led by Rob Miller and Zach Power.

Prior to Castalune, Rob and Zach met as early employees at the industry’s first brokerage house for corporate renewables, where they helped grow the business from pre-revenue to exit. Edison International acquired the business in 2015 through its deregulated subsidiary, Edison Energy. Rob and Zach stayed on post-acquisition to help lead the development of new analytics-driven capabilities for Edison Energy’s offerings spanning renewables origination, commodity procurement, and engineering.
