The company closed a $300 million equity financing led by TPG’s The Rise Fund. The startup expects to open its fourth hydroponic greenhouse—helping to make its lettuces accessible to more than half of the country’s population by 2026. Its lettuce is grown under glass and uses up to 90% less water than field-grown greens, according to the company. Founded in 2015, the company has now raised $435 million, according to Crunchbase data.
