XL Batteries is an innovative startup that operates in the energy sector, specifically focusing on energy storage. The company's primary mission is to enhance the efficiency of energy production and usage, thereby reducing waste within the existing energy infrastructure. XL Batteries aims to unlock the potential of renewable energy sources for a sustainable future.

The company's primary product is an industrial-scale flow battery, designed to store energy for use anywhere, anytime. This is a significant improvement over traditional energy storage methods such as pumped hydroelectricity, which is geographically limiting and makes up 95% of the US's energy storage.

XL Batteries serves a wide range of clients, including energy producers, industrial facilities, and renewable energy companies. The company recently partnered with Stolthaven Terminals to develop its flow battery, indicating a move towards large-scale commercialization.

The business model of XL Batteries revolves around the development, production, and sale of its flow batteries. The company generates revenue through the sale of these batteries to clients who need efficient, flexible energy storage solutions.

Recently, XL Batteries successfully closed a $10M Series Seed II funding round, with participation from Catalus Capital, Xerox Ventures, SIP Global, and founding investors Jeffrey Schwarz, Joel Greenblatt, and Robert Goldstein. This funding will likely be used to further develop and commercialize their technology.

In conclusion, XL Batteries is a promising startup in the energy sector, with a focus on revolutionizing energy storage to support the transition to renewable energy sources.
