Growing meat from cells: how Upside Foods built a new food category

Executive overview

Livestock meat requires slaughter, massive land and water use, and years of animal growth. Cultivated meat — grown directly from animal cells in clean facilities — can match the taste of conventional meat while shrinking resource use by up to 90%.

Upside Foods, founded in 2015, secured the first-ever FDA safety green light for a cultivated product in November 2022. The company now awaits final USDA labelling approval before its cultivated chicken reaches restaurant menus.

The core insight: building a new food category requires winning on science, regulation, and perception simultaneously — and inviting incumbents in rather than fighting them.

From cardiologist to cultivated meat pioneer

• Uma Valetti grew up in India with a veterinarian father; a childhood glimpse of animal slaughter behind a birthday party set a lifelong tension.
• At 19, witnessing industrial-scale slaughter, he stopped eating meat — while remaining a self-described meat lover.
• At the Mayo Clinic, injecting stem cells into cardiac patients sparked the question: why not grow meat cells the same way?
• Academics had discussed the concept for decades; no one had attempted it commercially.
• After failing to convince others to pursue it, Valetti founded Upside Foods in 2015 following a one-hour VC response.

The science: what cultivated meat is and isn't

• Real animal cells are taken from eggs or animals; cells capable of growing outside the body are identified and established as a stable line.
• Cells are fed clean nutrients and grown in cultivators; harvest takes two to four weeks versus nine months (pig) to two years (beef) for conventional livestock.
• The result is genuine meat — not a plant-based substitute — produced without slaughter.
• Future potential includes cell-editing to reduce inflammatory proteins, improve omega-3/6 ratios, and lower harmful fats — changes that take weeks in cells versus six to seven years in animals via selective breeding.

Navigating regulation: FDA and USDA

• Upside proactively engaged both the FDA and USDA in 2018, advocating for joint oversight rather than choosing one agency.
• Within nine months, the agencies published a joint industry guideline (March 2019) covering safety, labelling, and facility inspection.
• November 2022: FDA issued the first-ever safety green light for a cultivated food product globally — Upside's cultivated chicken.
• Remaining step: USDA label approval and a grant of inspection, expected early 2023, before restaurant sales can begin.

Building the industry: investors, terminology, and ecosystem

• Investors span impact-focused VCs, Bill Gates, Richard Branson, and incumbent meat giants Tyson Foods and Cargill — brought in for market access and credibility, not technology access.
• Tyson and Cargill hold no access to Upside's core IP; the arrangement mirrors Tesla bringing in automotive partners for scale, not for competitive advantage.
• Terminology matters: "clean meat" was dropped after incumbents objected; "lab-grown" became outdated once production moved to brewery-scale facilities; "cultivated" is the working standard.
• Long-term goal: build an open ecosystem — releasing IP, supporting hundreds of companies, enabling suppliers of ingredients, packaging, and cell lines — modelled on how the organic category developed.

Leadership lessons from cardiology

• The operating room trained Valetti in single-minded focus: the only goal is saving the patient. The equivalent at Upside is making meat a force for good.
• Perspective: distinguish what truly matters from rabbit-hole distractions.
• Resilience over perfection: a patient resuscitated after 90 minutes on the field — kept going when surgeons advised stopping — became a mental model for not giving up.
• Comfort with discomfort is a hiring filter; the field has no established playbook.

Scale and commercialisation roadmap

• Raised $400 million in April 2022 to fund a facility 20–30 times larger than the current California site.
• Target: facility operational late 2024 or first half 2025, capable of tens of millions of pounds of product.
• Initial sales channel: restaurants.
• The $2 trillion global meat, poultry, and seafood market is projected to double in 30 years; Upside aims to be the anchor player while openly supporting the broader ecosystem.
