The top indoor farming companies for 2027 are Little Leaf Farms, which grows more than half of North America’s indoor lettuce, Gotham Greens for rooftop and regional greenhouses supplying major grocers, Mastronardi Produce (Sunset) for greenhouse tomatoes, peppers and cucumbers at scale, Village Farms for large greenhouse produce operations, and Oishii for premium vertical-farmed strawberries. GoodLeaf Farms, BrightFarms, Eden Green, Vertical Harvest and Revol Greens round out the list.
Indoor farming has been through a brutal shakeout. Dozens of controlled environment agriculture companies have failed since 2022, including Bowery, AppHarvest and, in 2026, 80 Acres Farms, while Plenty went through Chapter 11 and now runs a single strawberry farm. The survivors mostly use sunlit greenhouses, focus on a few profitable crops and grow carefully. This list covers growers that are operating and supplying retailers today.
Mastronardi Produce, which sells under the Sunset brand, is one of North America’s largest greenhouse growers of tomatoes, peppers, cucumbers and berries.
Its scale and retail relationships make it a benchmark for greenhouse growing.
Vertical Harvest builds urban vertical farms that supply local grocers and employ people with disabilities.
It raised $59.5 million in debt financing in 2024 to build new farms.
10. Revol Greens — Midwest Greenhouse Lettuce At Scale
Revol Greens grows lettuce in large greenhouses in Minnesota and other states for national grocery chains.
Its sunlit greenhouse model keeps energy costs well below fully indoor vertical farms.
How We Chose These Companies
We focused on indoor and greenhouse growers that are operating today and weighed:
Scale of production and retail distribution
Financial stability after the industry shakeout
Crop focus and unit economics
Use of energy-efficient greenhouse or hybrid designs
Product quality and brand strength
What Separates The Indoor Farms That Survived
They use sunlight where they can
Greenhouse and hybrid designs cut the lighting and energy costs that sank many fully indoor vertical farms.
They focus on a few crops
Leafy greens, tomatoes and premium berries with strong retail demand have proven easier to make profitable than broad crop lists.
They grow carefully
Self-funded and cautious operators such as Little Leaf Farms have outlasted competitors that raised and spent heavily.
They sell through strong retail partners
Long-term grocery contracts give steady demand and pricing.
Frequently Asked Questions
What is controlled environment agriculture?
Controlled environment agriculture, or CEA, grows crops indoors or in greenhouses where light, temperature, water and nutrients are managed.
Why did so many vertical farms fail?
High energy and building costs, competition with cheap field-grown lettuce and fast spending left many vertical farms unable to reach profit.
Which indoor farming company is the largest?
Little Leaf Farms is the leader in indoor lettuce, while Mastronardi and Village Farms are among the largest greenhouse produce growers overall.
Is vertical farming still growing?
Yes, but more slowly. Companies are focusing on higher-value crops such as strawberries and on greenhouse hybrids.
Conclusion
Little Leaf Farms, Gotham Greens, Mastronardi and Village Farms lead on scale, Oishii shows that premium crops can work in vertical farms, and GoodLeaf, BrightFarms, Eden Green, Vertical Harvest and Revol Greens prove regional models can last.
