Planetary Nets $28M to Scale Full-Stack Fermentation Platform for Sustainable Proteins

Why It Matters

The capital infusion validates Planetary’s full‑stack, circular fermentation model and accelerates the shift toward ultra‑low‑cost, protein‑rich alternatives, reshaping supply chains in the alternative‑protein market.

Key Takeaways

• Planetary raised CHF16M ($20.4M) Series A, plus CHF6M credit.
• BioBlocks platform licenses fermentation tech to sugar and agro‑industrial partners.
• Targets ultra‑low‑cost mycoprotein production under $1 per kilogram.
• Acquired Libre Foods assets, launched mycoprotein fillet with Aldi Suisse.
• Plans second funding close to fund global expansion and product diversification.

Pulse Analysis

The alternative‑protein sector is entering a new phase where precision fermentation competes directly with traditional livestock on price. Planetary’s recent $28 million raise—unusual in a funding climate dominated by AI and defense—signals investor confidence in scalable, low‑cost protein solutions. By leveraging its BioBlocks platform, the Geneva‑based firm offers a turnkey pathway for agro‑industrial partners to convert sugar sidestreams into high‑value proteins, fibers, and enzymes, aligning with broader circular‑economy goals and reducing reliance on commodity crops.

At the core of Planetary’s strategy is a licensing model that turns sugar producers into protein manufacturers. The company’s technology can produce mycoprotein for under $1 per kilogram, a cost threshold that could undercut conventional animal protein in price‑sensitive markets. Recent partnerships with Swiss sugar giant Schweizer Zucker, Dutch cooperative Cosun, and Indian firm DBO illustrate a global rollout that taps diverse feedstock bases. The acquisition of Libre Foods’ IP and the launch of a mycoprotein fillet under Aldi Suisse’s MyVay brand demonstrate the commercial viability of the platform, achieving price parity with chicken and opening doors for hybrid and dairy‑free applications.

Looking ahead, Planetary plans a second funding close to accelerate infrastructure expansion, product diversification, and B2B launches across Europe. Its full‑stack capabilities—from strain development to industrial-scale production—provide a competitive moat in an increasingly crowded food‑tech landscape. As commodity volatility and geopolitical tensions pressure traditional protein supply chains, Planetary’s circular, low‑cost fermentation approach offers a resilient alternative that could reshape protein sourcing for both consumers and manufacturers.
