About us
Edit in settings
With our AI-powered fully automated optimization and trading platform for flexible energy assets from grid-scale batteries to virtual power plants, we ensure that energy is stored when it is abundant and released into the grid when it is needed. At the same time, by actively trading electricity, we counteract strong price fluctuations that green energies entail. Figuring out how storage provides the best value to the electricity grid and the highest returns to asset owners is how we accelerate the transition to a clean energy future.

At Echelon Corporation, I held various roles over six years, including Director of Product Management and Development in the Grid Modernization Division.
Before my endeavors in the Energy Industry I was working for Hewlett Packard in the Enterprise Software group for a little over 10 years.
