- E Green Global
Participated · Series B · Jan 2022
E Green Global produces potato microtubers via in‑vitro micropropagation inside sterile ‘plant factories,’ creating ~1 gram seed potatoes in about three months from tissue culture. The company supplies these lab-grown, virus‑free microtubers to farmers through contract‑farming and joint cultivation arrangements, often providing microtubers as part of an investment deal with partner growers. Its method removes the need for greenhouses, enables year‑round harvesting, shortens propagation cycles (two years versus six or more), reduces water and chemical inputs, and cuts logistics costs due to the microtubers’ small size. The firm emphasizes quality assurance and disease‑free seed as a path to improving yields in markets with low clean‑seed availability. E Green Global plans to replicate the approach for other crops but cites capital, time, and the need for market validation as key challenges. Financially, the Seoul‑based startup recently closed a $15 million Series B led by development and impact investors as it scales production and commercialization.

- Jellatech
Participated · Seed · Apr 2021
Jellatech, founded in 2020 by Stephanie Michelsen, develops cultivated collagen and gelatin via cellular agriculture with applications across food, personal care, biomedicine and materials. The company has demonstrated the ability to create both bovine and human collagen and is building a broader protein portfolio focused on proteins uniquely found in animals and humans. Jellatech plans to commercialize and scale production, prioritizing smaller, cost-effective use cases to begin generating revenue while pursuing larger market opportunities. The team views beauty and biomedical customers as attractive early markets with different regulatory pathways and diverse distribution channels. Management is focused on improving cost, efficiency and speed of production as it expands species and protein offerings. The startup raised capital to support these commercialization and scale efforts and remains agile across industries and applications. Jellatech, founded in 2020 by Stephanie Michelsen, positions itself as the world’s first cell-based collagen and gelatin ingredient company. The firm leverages a proprietary cellular agriculture process to manufacture sustainable, high-quality animal-free substitutes for collagen and gelatin. Its core product targets food applications and the company is also exploring uses in cosmetics, personal care and medication. Jellatech closed a $2 million pre-seed fundraise in April and counts Ryan Bethencourt’s Sustainable Food Ventures as a prominent investor. The company recently completed a strategic investment from CULT Food Science Corp. and plans to scale, pursue commercialization globally, and explore scientific synergies with CULT’s teams. Jellatech develops real collagen and gelatin via cellular agriculture rather than isolating them from meat-industry byproducts. Its products are biologically identical to native collagen, addressing functionality limitations of current animal-free and plant-based alternatives. The company targets applications across skincare and cosmetics, medical and pharmaceutical uses, and food & beverage. Jellatech reports several inquiries from potential customers and partners and will ship early samples by the end of the month. The startup says the new funding will accelerate product development and distribution of initial collagen samples. Stephanie Michelsen is co-founder and CEO.
