Vertical Farming’s Reckoning: After the Hype, a Harder Business Reality

What happened?

Vertical farming, once one of the most heavily funded categories in agricultural technology, has spent the past two years working through a painful correction. Several prominent companies in the sector, including AeroFarms, which filed for Chapter 11 bankruptcy in 2023 before restructuring, and Fifth Season and AppHarvest before it, either shut down, scaled back operations sharply or sold assets at a fraction of prior valuations. Survivors including Plenty and Infarm have restructured operations, closed some facilities and shifted strategy toward licensing technology or partnering with established agricultural companies rather than operating capital-intensive farms independently.

The reckoning follows a boom period, roughly 2018 to 2021, when venture capital poured billions of dollars into indoor and vertical farming startups on the promise that stacked, climate-controlled growing systems could produce fresh produce closer to cities year-round, reducing water use and transport emissions relative to conventional agriculture.

Key points

• AeroFarms filed for Chapter 11 bankruptcy protection in 2023 after raising hundreds of millions of dollars in venture funding, later emerging under new ownership with a smaller footprint.
• AppHarvest, a US indoor farming company that went public via SPAC in 2021, filed for bankruptcy in 2023.
• PitchBook and Crunchbase data show venture funding for vertical and indoor farming startups declined sharply from its 2021 peak.
• High energy costs for artificial lighting and climate control remain the central economic constraint on the sector's profitability, particularly after global energy price increases in 2022.
• Surviving companies are increasingly focused on high-value crops such as herbs, berries and specialty greens rather than staple commodity produce.

What we know

Data from venture research firms including PitchBook and Crunchbase show that agtech and vertical farming investment surged during the low-interest-rate period of 2020-2021 before falling substantially as interest rates rose and investors reassessed capital-intensive business models with long paths to profitability. Several of the most heavily capitalised vertical farming companies had built large-scale facilities predicated on continued access to cheap capital and falling LED lighting costs, an assumption that proved fragile once financing conditions tightened and energy prices spiked following the 2022 disruption to global energy markets.

Academic and industry analyses, including work published by agricultural economists and reported by trade outlets such as AFN (AgFunder News), have consistently identified energy costs — primarily for LED lighting and HVAC climate control — as the largest operating expense for most vertical farms, frequently exceeding labor costs and creating a structural cost disadvantage relative to sun-grown, open-field agriculture for all but the highest-value crops.

Background

Vertical farming's appeal rested on a combination of genuine advantages and, in retrospect, some overstated claims. Indoor, stacked growing systems can produce crops with far less water use and land footprint than field agriculture, protected from weather variability and, if located near cities, with shorter and lower-emission supply chains. These advantages attracted significant investor interest amid growing concern about climate change's impact on conventional agriculture and rising consumer interest in locally grown, pesticide-free produce.

However, the economics proved more difficult than early business plans suggested, particularly for companies that scaled rapidly and built large capital-intensive facilities before fully proving unit economics at smaller scale. Falling LED costs through the mid-2010s had made vertical farming more viable than in earlier decades, but the technology never fully closed the cost gap with field-grown produce for most crop types, leaving the business model dependent on premium pricing that not all consumers were willing to sustain, particularly as inflation squeezed household grocery budgets from 2022 onward.

Detailed analysis

The vertical farming sector's difficulties illustrate a recurring pattern in capital-intensive climate and agtech startups: technologies that are genuinely useful at the margin can still fail as venture-scale businesses if unit economics do not improve fast enough to justify the capital deployed, particularly once financing conditions tighten. Vertical farms that scaled to produce commodity greens such as lettuce found themselves competing directly on price with conventional agriculture, which benefits from free sunlight, established supply chains and decades of yield-improving breeding — advantages that indoor systems cannot easily replicate regardless of technological sophistication.

Surviving and newer entrants in the space have generally responded by narrowing their focus to crops where indoor growing offers a clearer value proposition: delicate herbs and berries with short shelf lives and high retail prices, specialty greens for premium retail and food-service channels, and, increasingly, licensing their growing technology and expertise to established food and agriculture companies rather than operating capital-intensive farms directly. This asset-light pivot mirrors a broader trend across capital-intensive climate-tech categories, where startups that once aimed to become vertically integrated operators are shifting toward technology-licensing or B2B service models with lower capital requirements.

Energy costs remain the crux of the sector’s prospects. Some vertical farm operators have begun pairing facilities with on-site renewable generation or locating near sources of cheap, low-carbon power, while others are betting that continued improvements in LED efficiency and automation will gradually narrow the cost gap with field agriculture over the coming decade, even if full parity for commodity crops remains unlikely in the near term.

Why it matters

Vertical farming's boom-and-correction cycle offers a broader lesson for climate-adjacent venture investing: technologies addressing genuine environmental and resource-efficiency problems can still fail commercially if capital structures assume unrealistic timelines or ignore fundamental cost drivers such as energy prices. The sector's difficulties do not necessarily invalidate the underlying technology, but they do suggest more disciplined, narrower business models focused on specific high-value niches are more likely to survive than ambitious plans to replace large swaths of conventional agriculture.

For food security policy, the setbacks are a reminder that controlled-environment agriculture, while a useful complement to conventional farming in specific contexts such as urban food deserts or water-scarce regions, is unlikely to substitute for field agriculture at the scale needed to feed a growing global population in the near term.

What happens next?

Expect continued consolidation in the sector, with weaker operators shutting down or being acquired for their technology and facilities at discounted valuations, while survivors narrow further toward high-value crop niches and licensing-based business models. Investment is likely to remain more selective than during the 2018-2021 boom, with venture capital favouring companies that can demonstrate clear paths to profitability at smaller scale rather than aggressive expansion plans premised on future cost reductions.

Watch for growing interest in hybrid models that combine vertical farming techniques with greenhouse agriculture, which uses natural sunlight and therefore avoids the largest cost disadvantage of fully enclosed indoor systems, as a potentially more durable middle path.

Insight Media Opinion

Insight Media Opinion: Vertical farming's correction was predictable to anyone who looked closely at its energy economics, and the sector's boom period is a useful case study in how venture capital can inflate capital-intensive climate technologies faster than their underlying unit economics can support. That is not an argument against the technology itself, which has genuine, if narrower, applications than its most enthusiastic backers claimed.

The companies most likely to survive are those retreating to defensible niches — high-value herbs, urban food-desert applications, technology licensing — rather than chasing the scale ambitions that sank AeroFarms and AppHarvest. Investors and founders in adjacent climate-tech categories, from lab-grown meat to green hydrogen, would do well to study this cycle closely: genuinely useful technology and venture-scale returns are not automatically the same thing, particularly when a business's largest cost line is something as volatile and structurally advantaged for incumbents as energy.
