BigHat Biosciences Raises $75 Million in Series B Funding to Design Safer, More Effective Antibodies

Capital will advance BigHat’s internal pipeline of therapeutics to patients, expand platform capacity 10-fold, and accelerate strategic partnerships


SAN MATEO, CA, July 20, 2022 — BigHat Biosciences, a biotechnology company developing safer, more effective antibody therapies for patients using machine learning and synthetic biology, today announced it has raised a $75 million Series B funding round, led by Section 32, with participation from new investors Amgen Ventures, Bristol Myers Squibb, Quadrille Capital, Gaingels, GRIDS Capital, among others. The investment brings BigHat’s total funding to date to $100 million.  Prior investors Andreessen Horowitz, 8VC, and AME Cloud Ventures also contributed to this round, which will be used to scale the capacity of MillinerTM, an integrated AI/ML- wet lab platform, advance therapeutic programs toward human clinical trials, aggressively hire drug discovery and development talent and to accelerate strategic collaborations with flagship partners.


More than 200 antibodies and other biotherapeutics are approved today as part of a global biologics market expected to grow to $421 billion by 2025. Next-generation antibody therapies promise improved safety and efficacy for patients. Developing these advanced molecules can be difficult, costly, and slow with conventional techniques. BigHat’s AI-enabled antibody design platform, Milliner, offers the essential technologies to quickly and reliably create these breakthrough therapies.


BigHat is using MillinerTM to design safer, more effective antibody therapies to treat some of the world’s most intractable conditions, from chronic illnesses to life-threatening diseases. At BigHat, every therapeutic program starts with a design blueprint and antibodies generated in our discovery engine or supplied by a partner. These initial molecules are then iteratively transformed into best-in-class next-generation therapies on the Milliner platform through sequential design-build-test cycles. BigHat’s machine learning models design hundreds of variants that are built and tested in our lab using the latest synthetic biology technologies in each cycle. These measurements include biophysical properties and impact on disease activity for every variant using cell-based or other functional assays that replicate in vivo disease processes. This new data is used to update the AI/ML models so that over multiple cycles, these models learn to create antibodies that match our design blueprint.


“BigHat is ushering the next wave of personalized medicines with a sophisticated AI platform integrated with a next-generation lab that addresses the complexities and inefficiencies associated with biologics discovery,” said Steve Kafka, PhD, Managing Partner of Section 32 and newly-appointed BigHat Board Member. “Section 32 is delighted to support BigHat’s mission and their quest to rapidly deliver safer and more effective antibody therapies for people suffering from today’s most challenging diseases.” Longtime Alphabet executive and Section 32 Managing Partner, Andy Harrison, co-led this Series B financing and will join as a Board Observer.


”Completion of the first stage of Amgen’s research collaboration with BigHat demonstrated the ability of their platform to quickly and significantly optimize next-generation single-domain antibodies, validating the platform as a path to generating target binders with improved properties compared with the original repertoire identified by traditional technologies,” said Philip Tagari, VP of Research at Amgen. “We’re excited to participate in the funding round to assist in the continued development and deployment of BigHat’s approach.”


The company was founded in 2019 by CEO Mark DePristo, a University of Cambridge biochemistry Ph.D., former Head of Genomics for Google.AI, and Co-director of Medical Genetics at Broad Institute, with CSO Peyton Greenside, a Stanford biomedical informatics Ph.D. and 2018 Schmidt Science Fellow.  Since that time, BigHat has reached significant business and scientific milestones, including:

Fit-for-purpose High Speed Wet Lab: scaled capacity of BigHat’s MillinerTM platform ten-fold since the Series A raise to design, synthesize, and characterize over four hundred antibodies weekly.  In March 2022, BigHat acquired Frugi Biotechnology to integrate customized cell-free protein synthesis (CFPS) technology into its platform. Additionally, mammalian cell line capabilities and functional assays were incorporated.

● Internal Pipeline: five discovery programs spanning oncology, inflammation and infectious disease are underway, leveraging the platform to design ultra high-quality next-generation antibodies.

Partner Collaboration: in January, BigHat completed the first stage of a research collaboration with Amgen.  BigHat is leveraging a synergistic partnering strategy focused on difficult antibody design challenges.

In 2021, Elizabeth Schwarzbach, a University of Pennsylvania pharmacology PhD with over 20 years of pharma, biotech, and academic drug discovery and development experience, joined as CBO.

Talent & Expansion: currently the company has 37 employees and moved into a dedicated lab and office space in San Mateo, CA.  Team size is expected to double in the next 12-18 months.

AI/ML technology: recent work developing active learning methodologies in collaboration with NYU was published in a paper titled, “Effective Surrogate Models for Protein Design with Bayesian Optimization,” and accepted to the 2022 International Conference for Machine Learning (ICML). BigHat developed numerous proprietary training data sets and deployed both generative and active learning models.

Investment and Grants: in addition to its $5 million seed and $19 million Series A rounds, BigHat was awarded a Small Business Innovation Research (SBIR) grant from the National Institute of Standards and Technology (NIST).  The company received Amgen’s 2021 Golden Ticket to MBC BioLabs, was named to Business Insider’s 24 top biotech companies list, awarded the UCSF Health Award and named Therapeutics Innovation of the Year by the BioTech Breakthrough Awards.


“The scale and flexibility of the BigHat platform allows us to partner with companies anywhere along the therapeutic discovery continuum as well as pursue internal therapeutics programs to address major unmet needs across a variety of diseases,” said BigHat co-founder and CEO Mark DePristo. “Combining internal programs and partnerships enables us to bring as many assets to market as quickly as possible. All while capturing a wealth of data to continuously improve our AI/ML models and wet lab techniques, making future campaigns faster and better.

BigHat Biosciences Raises $19 Million in Series A Funding to Advance Antibody Design and Development for Safer, More Effective Treatments

Andreessen Horowitz-led investment fuels hiring and R&D for AI-enabled experimental platform that speeds the antibody engineering process 


SAN CARLOS, CA, February 10, 2021BigHat Biosciences, a novel protein therapeutics company and developer of an AI-guided antibody design platform, today announced it has raised $19 million in an oversubscribed Series A funding round, led by Andreessen Horowitz, with participation from prior investors 8VC, AME Cloud Ventures, and Innovation Endeavors. As part of the investment, Andreessen Horowitz General Partner, Vineeta Agarwala, MD, PhD joins BigHat’s Board of Directors.

Biologics represent a rapidly growing therapeutic category.  As of 2019, seven of the top ten drugs were biologics and there are currently more than 200 biotherapeutics in use, generating more than $100 billion in annual revenue for drug companies developing treatments for indications ranging from oncology to auto-immunity to infectious disease.  

“Our mission is to improve human health by making it far easier to create advanced, next-generation antibody and protein therapeutics.  BigHat is transforming antibody design from bulk screening to data-driven engineering to give precise control over the antibodies’ molecular properties.  Leveraging recent advances in synthetic biology and machine learning, our platform measures and optimizes antibodies for the biophysical and functional properties needed for cutting-edge therapeutic applications,” said BigHat Co-founder and CEO Mark DePristo, PhD.

BigHat integrates a wet lab for high-speed characterization with machine learning technologies to guide the search for better antibodies. This approach dramatically speeds up design and discovery data acquisition cycles to days rather than weeks or months. It also provides greater optionality, eliminating the need for premature candidate selection and enabling the simultaneous measurement of a vast array of key biophysical properties of many molecules.   

“There are very few biologic applications in which you can pose a hypothesis and have real, experimentally validated answers in days.  BigHat’s molecular engineering methods allow us to optimize antibodies for affinity, stability, solubility, and even performance in a functional assay,” added BigHat Co-founder and Chief Scientific Officer (CSO) Peyton Greenside, PhD. “We’ve just started to explore the potential for novel antibody and protein therapeutics enabled by BigHat’s approach to discovery.”

Supercharged Antibody Development

Existing technologies only solve a sliver of the full design problem and traditional lab workflows take weeks-to-months to produce a protein variant and characterize its behavior. BigHat’s experimental platform reduces the time to enter clinical development by accelerating candidate discovery and validation. 

“The relevant search space for protein therapeutics is orders of magnitude larger than a purely experimental approach anchored in naturally-occurring sequences can efficiently traverse,” said Vineeta Agarwala, General Partner at Andreessen Horowitz.  “This is why we believe BigHat’s platform, which combines machine learning, synthetic biology, and high-throughput experimentation, holds tremendous promise.”

AI-Accelerated Momentum

Founded in late 2019, BigHat has experienced rapid growth during its proof-of-concept stage, reaching significant corporate and scientific milestones in its first 15 months.  BigHat’s wet lab is actively producing and characterizing antibodies at scale.  The cloud-based AI/ML platform improves designs each round by combining active learning with assay modeling of critical biophysical properties leading to the highest quality sequences.  At the onset of the COVID-19 pandemic, BigHat validated this platform by engineering a potent neutralizing SARS-CoV-2 bispecific antibody in the lab.  

Following this platform demonstration, in late 2020, BigHat was awarded Amgen’s Golden Ticket to MBC BioLabs, which entitles them to lab bench space as well as access to the life sciences incubator community and Amgen’s scientific and business leaders.  The company was also awarded a Small Business Innovation Research (SBIR) grant for improving protein production from the National Institute of Standards and Technology (NIST).  BigHat is collaborating with multiple strategic partners to leverage the platform to co-develop antibodies and other biotherapeutics.

The new capital will be used to expand the BigHat scientific and technical teams; the company is actively hiring exceptional antibody and protein engineers, AI/ML engineers, and computational biologists.  Additionally, the funding will support further platform development, scaling capacity and advancement of BigHat’s own internal therapeutic programs towards human clinical trials. 

“BigHat is applying AI in a dramatically different way than most life sciences startups.  AI is by its nature iterative and so is drug development, but in a traditional lab you have long wait times between generations of data as discovery is done and redone.  In BigHat’s wet lab, the platform increases throughput, speeds the feedback loop and really eliminates some of the cost and time barriers standing in the way of optimizing protein therapeutics,” said Francisco Gimenez, Partner at 8VC.

Founding Team and Advisory Board

The company was founded by CEO Mark DePristo, PhD, University of Cambridge, and CSO Peyton Greenside, PhD, Stanford, along with founding advisor Theresa Tribble, a Harvard University MBA and former Chief Business Officer (CBO) for Everlywell. Liz Schwarzbach, PhD, University of Pennsylvania, recently joined as CBO.  

BigHat has assembled a world-class group of technical and business advisors.  Scientific and business leaders advising the company span chemistry luminaries (Brian Kobilka, Nobel Laureate), AI and deep learning experts (Jake Gardner and Andrew Gordon Wilson), life sciences entrepreneurs (Stan Lapidus) and biologics drug discovery leaders (Greg Landes), among others.

BigHat Biosciences earns Phase I award from NIST to show power of AI-driven platform

BigHat Biosciences received a Phase I SBIR award from NIST (National Institute of Standards and Technology) to apply its AI-driven platform to rapidly identify high-yield expression vectors for therapeutic antibody production.

BigHat’s Chief Scientific Officer, Dr. Peyton Greenside, noted, “We are honored that NIST sees the potential for our approach. This Phase I study will demonstrate that BigHat’s platform can design novel and improved DNA templates by querying only a tiny fraction of candidate sequences in a massive search space.”

The Phase I SBIR grant aims to increase protein production by jointly optimizing a 30 base pair DNA sequence involving the expression cassette and start of the protein coding sequence through tight coupling of computational and experimental evaluation on the BigHat platform. Sequences longer than ~10 base pairs have been historically intractable to search effectively because the search space is simply too large for comprehensive experimental exploration.

“We started BigHat Biosciences because we believe that AI/ML-powered molecular engineering will allow us to design biotherapeutics inaccessible to traditional approaches,” shared CEO Mark DePristo, PhD. “Our work with NIST will help BigHat benchmark and further improve our technologies for data-driven antibody design.

BigHat founder presents active learning innovations at ICML 2020

​BigHat founder Peyton Greenside and BigHat consultant Vivek Myers presented their work A Hierarchical Approach to Scaling Batch Active Search Over Structured Data at the ICML Workshop on Real World Experiment Design and Active Learning. The method enables efficient, large-batch search over a structured set of protein or DNA sequences by combining deep representation learning with a hierarchical search strategy. It balances broad exploration over unobserved sequence space with more greedy local search where promising sequences have been identified. These innovations were possible by taking advantage of the natural emergent structure in a large corpus of related biological sequences to help guide experimental design in a high-throughput setting.
