Antheia: Funding, Investors & Team (Oct 2026)
Antheia focuses on creating biosynthetic key starting materials (KSMs) and active pharmaceutical ingredients (APIs) for important medications through synthetic biology. By manipulating yeast to recreate intricate biosynthetic pathways, the company transforms basic sugars into pharmaceutical substances using fermentation. This method is designed to lessen the need for traditional farming sources and chemical production, providing a more dependable supply chain. Antheia's range of products includes compounds for medical fields like neurology, oncology, and gastroenterology. The company assists pharmaceutical collaborators from initial development to regulatory approval to promote the use of biomanufactured ingredients.
Antheia has raised $132M across 4 funding rounds on record, the most recent a Series C of $24.0M announced in Jan 2026.

About FundedIQ's Antheia Funding Data
FundedIQ tracks announced funding rounds and refreshes this profile every week. Round dates, stages and amounts are normalised to a single format, converted to US dollars, and de-duplicated: two records of the same round announced days apart are merged, and two genuinely different rounds are kept apart on the amounts they disclose. Amounts shown are the disclosed figures only — a round announced without a number is listed and excluded from the total rather than estimated.
Employee counts are reported bands, not exact headcounts. Founder and executive names carry the job title on record. Anything we do not hold for Antheia is left off this page rather than filled in.
