2025
Shuts down after burning through $941M
Root Causes
Plenty aimed to revolutionize agriculture with indoor vertical farms growing produce year-round using LED lighting and robotics. Despite nearly $1B from SoftBank and Jeff Bezos, the energy costs alone made produce 5-10x more expensive than field-grown alternatives. The Compton, CA mega-farm underperformed expectations. The company shut down in 2025, joining a growing list of vertical farming failures (AeroFarms, AppHarvest).
