Xaira Therapeutics

Company Overview

Xaira Therapeutics is an integrated biotechnology company founded in 2024 and headquartered in Brisbane, California. The company aims to leverage advances in artificial intelligence to transform drug discovery and development, with the goal of delivering new medicines to treat disease.

Xaira launched publicly in April 2024 with over $1 billion in funding, making it one of the largest-ever initial bets on using AI for drug development. The company was incubated and backed by prominent biotech investors ARCH Venture Partners and Foresite Labs.

Products Overview

Xaira is developing an end-to-end AI-powered platform for drug discovery and development. This includes:

• Machine learning models to better understand biology and predict drug properties
• Large-scale data generation capabilities to train AI models
• Robust therapeutic product development programs

The company aims to use its AI platform to design novel drug candidates and advance them through preclinical and clinical development. Xaira is taking an integrated approach spanning machine learning research, data generation, and therapeutic development.

Founding Team

• Marc Tessier-Lavigne - CEO and Co-Founder. Former president of Stanford University and chief scientific officer at Genentech.

• Bob Nelsen - Co-Founder. Managing Director at ARCH Venture Partners.

• David Baker - Co-Founder. Director of the Institute for Protein Design at the University of Washington.

• Vijay Pande - Co-Founder. General Partner at Andreessen Horowitz.

• Vik Bajaj - Co-Founder. CEO of Foresite Labs and Managing Director at Foresite Capital.

Problem and Market Fit

Xaira aims to address the high failure rates and long timelines in traditional drug discovery and development. By leveraging AI and large-scale data, the company believes it can dramatically improve the efficiency and success rates of bringing new medicines to patients.

The company is positioning itself at the intersection of rapid advances in AI/machine learning and unmet medical needs across many disease areas. Xaira’s integrated approach spanning computational and experimental methods aims to overcome limitations of narrower AI drug discovery efforts.

Business Model

While specific details are limited, Xaira appears to be pursuing an integrated biotech business model where it will use its AI platform to discover and develop its own pipeline of drug candidates. The massive funding allows the company to take a long-term approach to building both cutting-edge technology and a robust therapeutic pipeline.

Funding and Runway

Xaira launched with over $1 billion in initial funding, one of the largest-ever Series A rounds for a biotech startup. Key investors include:

• ARCH Venture Partners
• Foresite Capital
• Andreessen Horowitz
• F-Prime
• NEA
• Sequoia Capital
• Lux Capital
• Lightspeed Venture Partners
• Menlo Ventures
• Two Sigma Ventures
• SV Angel

With this massive funding round, Xaira likely has runway for 5+ years of operations to build out its platform and advance drug candidates.

Competitive Landscape

Xaira enters a competitive landscape of companies applying AI to drug discovery, including:

• Recursion Pharmaceuticals
• Insitro
• Generate Biomedicines
• Exscientia
• BenevolentAI
• Atomwise

However, Xaira’s integrated approach and massive funding allow it to take a more comprehensive platform approach compared to some more narrowly focused competitors.

Customers

As an early-stage drug discovery company, Xaira does not yet have commercial customers. Its “customers” will ultimately be patients who could benefit from any medicines the company develops. Xaira may also potentially partner with pharmaceutical companies in the future to advance drug candidates.
