## About

Based in Massachusetts, US, and founded in 2020, Florrent operates as a deep technology company that develops energy-density ultracapacitors for renewable energies and it will work towards stabilization of electrical grids. The company was founded by Jose LaSalle (CEO), Alex Nichols (Chief engineer), and Joe Hastry (COO/CFO). In September 2025, Florrent raised USD 9.5 million in seed funding led by returning investor MassVentures, with participation from new investors Raven Indigenous Capital Partners, Sky Foundation, Elbezius, and Maroon Venture Partners. Individual investors and returning investors MassMutual Ventures and Boston Impact Initiative also participated in the round.

The company develops ultracapacitors that are used to stabilize electrical grids and address critical bottlenecks for the adoption of renewable energies, electric vehicles, and net-zero buildings. The ultra-capacitators are manufactured using biomass. It offers Contoured Carbon™ which is a pure-carbon electrode energy storage medium that offers performance to symmetric EDL Capacitors.

The company will use the September 2025 funding to scale production of Contoured Carbon™, a material for supercapacitors that supports grid stability and lowers costs.
