Breakthrough Energy Ventures, the venture arm of a climate-focused organization launched by Bill Gates, is raising an $839.4 million fund, a recent filing with the Securities and Exchange Commission shows.
A Breakthrough Energy spokesperson Monday said in an email the firm is working on its third fund but didn't give details on the timeframe or size of the fund.
The spokesperson added the new fund will focus on similar areas as previous funds, "encompassing climate innovations in five key investment areas: electricity, transportation, manufacturing, buildings, and food and agriculture."
Breakthrough Energy Ventures is headquartered in Boston, according to the SEC filing, but the larger organization says on LinkedIn it is based in Kirkland.
