Nabla Bio

Our mission is to enable pharmaceutical and biotech companies to bring more antibody therapies to patients. Using AI and massively parallel experimentation, we design antibodies that precisely bind the disease target at the right location, while minimizing manufacturability and toxicity risks. We are a well-funded, revenue-generating, bilingual company of wet- and dry-lab scientists, and are founded by AI and protein design experts from Harvard University.

High-Level Overview

Nabla Bio is a U.S.-based biotechnology company that uses advanced artificial intelligence (AI) to design *de novo* antibodies targeting intractable diseases, including hard-to-drug membrane proteins like G protein-coupled receptors (GPCRs). Their proprietary AI platform, called Joint Atomic Model (JAM), generates entirely new antibody sequences optimized for affinity, manufacturability, and drug-like properties, enabling a rapid design-to-experiment feedback loop of just three to four weeks—the fastest in the industry. Nabla serves pharmaceutical partners and aims to accelerate therapeutic development by overcoming traditional antibody discovery limitations, focusing on diseases with high unmet medical need. The company has demonstrated strong growth momentum, securing multi-million dollar partnerships, notably a second major collaboration with Takeda Pharmaceutical potentially worth over $1 billion in success-based payments[1][2][3].

Origin Story

Nabla Bio was co-founded in 2020 by Surge Biswas, PhD, and Anastassacos, who brought together expertise in AI, protein design, and biotechnology. The idea emerged from deep scientific discussions and a shared vision to transform drug development from a trial-and-error process into a design-driven discipline. Early traction came quickly with $11 million in seed funding from prominent investors like Khosla Ventures and Zetta Venture Partners in 2021. The company’s breakthrough was the development of JAM, an AI system trained on massive protein sequence and structure data combined with proprietary human-relevant biological measurements, enabling the rapid generation and validation of antibody candidates[3][6].

Core Differentiators

• Proprietary AI Platform (JAM): Multimodal generative modeling system that "autocompletes" antibody sequences based on target protein context, enabling precise epitope targeting and high hit rates.
• Speed and Scale: Parallel *de novo* antibody design allows multiple campaigns simultaneously, compressing timelines from years to weeks.
• Integrated Dry/Wet Lab Engine: Combines AI design with rapid experimental validation, characterizing binding properties of up to 100,000 antibodies in parallel within weeks.
• Focus on Hard-to-Drug Targets: Excels at designing antibodies for challenging membrane proteins like GPCRs, including multispecific antibodies and receptor decoys.
• Optimized Therapeutic Properties: Designs antibodies with favorable pharmacokinetics, low immunogenicity, manufacturability, and drug-like properties without extensive optimization.
• Strong Industry Partnerships: Expanded collaboration with Takeda Pharmaceutical, emphasizing tackling the most pressing scientific barriers in early drug discovery[1][2][4][5].

Role in the Broader Tech Landscape

Nabla Bio rides the wave of AI-driven innovation in biopharmaceutical R&D, a sector increasingly focused on leveraging computational methods to accelerate drug discovery. The timing is critical as traditional antibody discovery methods are slow, costly, and limited in scope, especially for complex targets like GPCRs. Market forces favor scalable, AI-powered platforms that can generate novel biologics with precision and speed, addressing unmet medical needs in oncology, immunology, and beyond. Nabla’s approach exemplifies the shift from empirical screening to rational design, influencing the broader ecosystem by demonstrating that AI can produce therapeutic-grade antibodies rapidly and reliably, potentially reshaping how biologics are discovered and developed[1][3][7].

Quick Take & Future Outlook

Looking ahead, Nabla Bio is poised to expand its platform capabilities to more challenging targets such as ion channels and to develop antibodies recognizing specific receptor conformations, further enhancing therapeutic precision. The company’s success will likely be shaped by ongoing advances in AI, integration of patient-relevant biological data, and deepening partnerships with pharmaceutical companies. As AI models improve and hit rates increase, Nabla could lead a paradigm shift in biologics discovery, moving the industry toward fully design-driven drug development. Their continued innovation and validation in clinical settings will be key to cementing their influence in the biotech landscape and delivering new treatments for diseases previously considered intractable[5][6].
