| Jan 2026 | Series C | America’s Frontier Fund (lead); ATHOS KG (lead); Global Health Investment Corporation | $24M | Antheia is an advanced biosynthesis company focused on 21st-century pharmaceutical manufacturing and innovation, producing critical pharmaceutical ingredients like thebaine, a key component for Narcan. On January 27, 2026, it completed a second close of its Series C financing, raising an additional $24 million led by ATHOS KG and America's Frontier Fund, with participation from existing investors including Global Health Investment Corporation, which co-led the initial Series C with EDBI. Combined with other capital and non-dilutive funding such as U.S. government project agreements, Antheia secured over $175 million in the past year. Proceeds will expand commercial manufacturing capacity, advance its pipeline of late-stage biosynthetic pharmaceutical ingredients to market, and establish U.S. manufacturing operations to support national onshoring priorities. This follows milestones like the first commercial delivery of thebaine, two U.S. government agreements to onshore supply chains, and a November 2025 strategic partnership with TAPI for pipeline commercialization. America's Frontier Fund highlighted Antheia's role in strengthening U.S. industrial leadership, securing supply chains, and addressing medicine shortages, long lead times, and geopolitical risks through scalable domestic manufacturing. |

Lead investors included EDBI and Global Health Investment Corporation, alongside ATHOS KG, Civilization Ventures, Federov Investments, IQT, S-Cubed Capital, Sherpalo Ventures, and Viking Global Investors. This followed milestones like the first commercial delivery of thebaine, two U.S. government project agreements worth up to $23 million, and a November 2025 strategic partnership with TAPI. On January 27, 2026, Antheia completed the Series C with a second close of $24 million, bringing total funds raised in the past year to over $175 million including non-dilutive capital.

| Jul 2024 | Series A | Echo Investment Capital; Viking Global Investors; IQT | $6M | Antheia is a pharmaceutical ingredient manufacturer using whole-cell engineering and biomanufacturing in yeast to produce critical pharmaceutical ingredients, aiming to onshore production to the U.S. and end drug shortages. On July 19, 2024, the company announced $17 million in new funding, including a non-dilutive project agreement up to $11 million from the Biopharmaceutical Manufacturing Preparedness Consortium (BioMaP-Consortium) and matching investment from In-Q-Tel (IQT), Echo Investment Capital, Viking Global Investors, and existing investors. The funding supports domestic production of essential medicine supply chains and accelerates commercialization, following validation of its first product, thebaine, and plans to ship initial customer orders in 2024. |
| Jun 2021 | Series B | Viking Global Investors (lead); Irregular Expressions; Sherpalo Ventures; Hillspire | $73M | Antheia is a Menlo Park, California-based synthetic biology company developing a platform for next-generation plant-inspired medicines, focusing on producing complex pharmaceuticals through engineered microbes as an alternative to plant extraction or synthetic chemistry. The company targets essential medicines to address drug shortages by enabling resilient, agile production of active pharmaceutical ingredients (APIs) and key starting materials (KSMs). On June 30, 2021, Antheia raised $73 million in an oversubscribed Series B financing round led by Viking Global Investors, with participation from Sherpalo Ventures, Hillspire, and Irregular Expressions. The funds are designated to commercialize its first pharmaceutical compounds, expand the product pipeline, scale production for global markets, and bring plant-based medicines to market while decoupling from unpredictable harvests and unsustainable supply chains. Antheia has validated its platform by producing a KSM for essential medicines at commercially relevant titers in 300L pilot-scale runs, demonstrating chemical equivalence to plant-extracted material, and biosynthesizing four major classes of plant-based medicines. Prior to this round, the company had raised additional funding, bringing total funding to around $136 million as of that time. The company continues to innovate in synthetic biology to improve production time, scale, and cost for critical plant-inspired drugs. |
