Hippo Harvest Raises $30M Series C, Plans 30-Acre Robotic Farm

Hippo Harvest, a California-based indoor greens grower, closed a $30 million Series C round led by Cox Farms, North America's largest greenhouse operator. The company said it will use the funds to build a 30-acre facility in Hollister, California, and develop a next-generation robotic growing system.

Hippo Harvest grows USDA-certified organic leafy greens in greenhouses powered by autonomous mobile robots. The robots function as indoor tractors, handling tasks like moving trays and harvesting. The closed-loop system recaptures water and delivers nutrients directly to roots. The company says it cuts water use by 92% and land use by 94% compared with field farming.

The round included existing investors Congruent Ventures, Hawthorne Food Ventures, Collaborative Fund, and the Fresh Investment Club.

Venture capital funding for indoor agriculture has cooled from pandemic-era highs. Several high-profile vertical farming startups, including AppHarvest and AeroFarms, have struggled with costs and scalability. AppHarvest filed for Chapter 11 in 2023. AeroFarms went public via SPAC and has yet to report a profit.

Hippo Harvest uses greenhouses rather than fully vertical stacks, keeping energy costs lower by relying on natural light. Its robotics layer automates labor-intensive tasks, a major expense in any growing operation. Its product mix blends greenhouse greens with field-grown organic greens, giving retailers year-round supply without requiring them to fully switch to indoor produce.

Cox Farms operates a vast greenhouse network across North America. Its investment brings operational expertise and potential distribution channels to Hippo Harvest. The backing signals a shift in the indoor ag sector toward operators with proven unit economics and a clear path to scale.
