Company Overview and Leadership

Cradle.bio was founded by a team of entrepreneurs and scientists with deep expertise in both technology and biology. The co-founders are Jelle Prins, who has a background as an early employee at Uber, and Stef van Grieken, a former leader at GoogleX. This unique combination of tech and biotech expertise is central to the company's approach. Stef van Grieken serves as the CEO. The company has secured over $100 million in funding from prominent investors, including IVP, Index Ventures, and Kindred Capital. A key part of their strategy is to combine computational and experimental work, as evidenced by their in-house state-of-the-art wet lab in Amsterdam. This allows them to generate proprietary datasets, fine-tune their AI models, and validate their predictions, ensuring a high level of reliability for their customers.

Products and Services

Cradle.bio's primary offering is a software platform that leverages generative AI to assist scientific teams in engineering proteins. The platform is designed to be user-friendly, allowing biologists to use advanced computational tools without needing to be experts in bioinformatics or machine learning. The services and products can be broken down as follows:

• AI-Powered Protein Design Platform: This is the core product, a web-based software that enables researchers to design and optimize proteins. The platform allows scientists to upload protein sequences and set specific objectives, such as improving binding affinity, thermostability, expression, or enzymatic activity. The generative AI models then propose novel protein sequences and mutations that are more likely to achieve the desired properties. This process significantly reduces the number of experimental rounds needed in a lab.
• Predictive Algorithms and Generative Machine Learning Models: The company's technology is built on proprietary generative AI models that are trained on billions of protein sequences, as well as data from their own wet lab. These models are able to create a "local fitness landscape" from a customer's experimental data, helping to identify novel and effective mutations that might be missed by human-driven or traditional methods.
• Co-optimization of Protein Properties: The platform is not limited to optimizing a single property. It is capable of co-optimizing multiple protein properties simultaneously, which is a major challenge in traditional protein engineering. This capability allows for the creation of more effective and well-rounded protein candidates.
• Lab Validation: Cradle.bio operates its own wet lab to ensure the quality and performance of its models. This hands-on approach is a key differentiator, as it allows the company to continuously refine its AI by integrating real-world experimental data. This also provides customers with confidence that the AI-generated designs are based on a reliable foundation.
• Data Security and IP Protection: Recognizing the sensitive nature of their clients' research, Cradle.bio emphasizes data security and intellectual property protection. The platform ensures that each user's data is private, secure, and not used to train models for other organizations. Clients maintain complete IP ownership of any sequences generated using the platform.

Applications and Impact

The platform's capabilities have a wide range of applications across multiple industries, including therapeutics, agriculture, food, and chemicals. The company's customers include major industry players like Novo Nordisk, Johnson & Johnson, and IFF. Cradle.bio's technology has been shown to drastically accelerate research and development projects, with reported speed-ups of 1.2x to 12x and cost reductions of up to 90% in some cases. The company is a founding member of the Advanced Biotech for Sustainability (AB4S) coalition, which aims to accelerate the adoption of advanced biotechnology solutions to create a more sustainable world. This aligns with Cradle.bio's vision of using AI to develop sustainable products like animal-free foods, eco-friendly pesticides, and new materials that can replace those made from fossil fuels.
