Sep 2026Series CDFJ Growth (lead); Premji Invest (lead); Amgen Ventures; Sigmas Group; LG Technology Ventures; S32; Andreessen Horowitz; Catalio Capital Management; Quadrille Capital; Eli Lilly; Discovery Ventures; Intermountain Ventures$75MBigHat Biosciences, a clinical-stage AI-driven protein therapeutics platform company, announced completion of a $75 million Series C financing on September 24, 2026, bringing total funding to $223 million. The round was co-led by DFJ Growth and Premji Invest with participation from Catalio Capital Management, LG Technology Ventures, Sigmas Group, 8VC, Alexandria Venture Investments, Amgen Ventures, Andreessen Horowitz, Discovery Ventures, GRIDS Capital, Intermountain Ventures, Eli Lilly and Company, Merck Global Health Innovation Fund, Quadrille Capital, and Section 32. Proceeds will advance BigHat’s clinical-stage pipeline, including BHB810 (first patient dosed in Phase 1 for gastric cancer) and BHB299 (nearing clinical entry), plus expansion of its AI/experimental platform for rapid protein design and data generation. The company has also formed collaborations with Amgen, Merck, J&J, AbbVie, and Lilly.
Jul 2022Series BS32 (lead); GRIDS Capital; Amgen Ventures; 8VC; AME Cloud Ventures; Andreessen Horowitz; Bristol-Myers Squibb; Quadrille Capital; Gaingels$75MBigHat Biosciences is a biotechnology company developing safer, more effective antibody therapies using machine learning and synthetic biology to treat intractable conditions like chronic illnesses, life-threatening diseases, oncology, inflammation, and infectious diseases, including a pan beta coronavirus antibody program. The company raised $75 million in a Series B funding round on July 20, 2022, led by Section 32, with participation from new investors Amgen Ventures, Bristol Myers Squibb, Quadrille Capital, Gaingels, GRIDS Capital, and others, including prior investors Andreessen Horowitz, 8VC, and AME Cloud Ventures. This brought total funding to $100 million, following a $5 million seed, $19 million Series A, and an SBIR grant from NIST. The proceeds will scale the capacity of Milliner, BigHat's integrated AI/ML-wet lab platform, which has grown tenfold since Series A and designs hundreds to thousands of antibodies weekly. Funds will advance five internal preclinical discovery programs toward human clinical trials, hire drug discovery talent, and accelerate strategic collaborations with partners like Janssen Biotech and Merck. The platform iteratively designs, tests, and refines antibodies to match therapeutic blueprints, capturing data to improve models over cycles. Section 32 Managing Partner Steve Kafka joined the board, praising BigHat's AI platform addressing biologics discovery inefficiencies, while co-lead Andy Harrison became a board observer. BigHat received awards including Amgen’s 2021 Golden Ticket to MBC BioLabs, UCSF Health Award, and Therapeutics Innovation of the Year by BioTech Breakthrough Awards, and was named to Business Insider’s top 24 biotech companies list. One source mentions a later $124.1 million Series B extension at $180 million valuation, but primary announcements confirm the core $75 million round matching the specified investors and date.
Feb 2021Series AAndreessen Horowitz (lead); 8VC; Innovation Endeavors; AME Cloud Ventures$19MBigHat Biosciences is a biotechnology company founded in late 2019 that develops an AI-guided antibody design platform integrating machine learning with a high-throughput wet lab to engineer safer and more effective antibody therapeutics, particularly for challenging diseases. The platform uses active learning and assay modeling to optimize antibody sequences iteratively, accelerating the feedback loop in protein engineering and enabling access to novel, manufacturable sequences not found in nature. On February 10, 2021, BigHat announced an oversubscribed $19 million Series A funding round led by Andreessen Horowitz, with participation from prior investors 8VC, AME Cloud Ventures, and Innovation Endeavors. Vineeta Agarwala from Andreessen Horowitz joined the board. This followed a $5.3 million seed round in 2019 led by 8VC, bringing total funding to approximately $24.3 million at that point. The funds were allocated to expand scientific and technical teams, including hires for antibody/protein engineers, AI/ML engineers, and computational biologists, as well as to advance platform development, scale wet lab capacity, and progress internal therapeutic programs toward human clinical trials. By early 2021, the company had validated its platform by engineering a SARS-CoV-2 neutralizing bispecific antibody during the COVID-19 pandemic and was producing antibodies at scale. BigHat positions itself uniquely by shifting from traditional experimental screening of limited protein sequences to AI-driven engineering across vast parameter spaces, aiming to boost productivity in biologics drug development. Subsequent developments included a $75 million Series B in July 2022 led by Section 32, with participation from prior investors and new ones like Amgen Ventures and Bristol Myers Squibb, bringing total funding to $100 million. The company also secured grants like an SBIR from NIST and recognitions such as Amgen’s Golden Ticket.

The company develops an AI-guided antibody design platform to create safer and more effective protein therapeutics. 8VC participated as an investor in this early funding. Subsequent rounds included a $19 million Series A in February 2021 led by Andreessen Horowitz with 8VC participation, and a $75 million Series B in July 2022 led by Section 32, bringing total funding to $100 million at that point.
