Cradle's AI-Powered Protein Design: A Game-Changer in Biotech

In the world of biotechnology and artificial intelligence, one company is making waves with its groundbreaking approach to protein design. Cradle, a biotech and AI startup, has recently secured a substantial $24 million in funding, thanks to its innovative platform that leverages the power of artificial intelligence to interpret and manipulate the complex language of amino acid sequences.

Proteins are the building blocks of life, and their design plays a crucial role in various fields, including pharmaceuticals, food production, and industrial applications. Traditionally, protein design has been a time-consuming and labor-intensive process, requiring extensive experimentation and trial and error. However, Cradle is changing the game by harnessing the power of Artificial Intelligence to revolutionize the way proteins are designed and developed.

What sets Cradle apart from other AI biotech companies is its unique perspective on protein design. While many companies focus on training AI models to understand the molecular structures of proteins, Cradle takes a different approach. It views the sequences of amino acids in proteins as a complex “alien programming language.” Instead of expecting scientists to decipher this intricate code, Cradle envisions Artificial Intelligence as the interpreter, bridging the gap between humans and proteins.

By utilizing AI to interpret and manipulate amino acid sequences, Cradle’s platform enables scientists to collaborate more effectively and efficiently. The platform allows users to select the most promising protein candidates based on factors like survival in specific conditions. This approach has caught the attention of prominent pharmaceutical companies like Johnson & Johnson and Novozymes, who see the potential for Cradle’s technology to streamline and accelerate the protein development process.


The benefits of using Cradle’s AI-powered protein programming platform

Unparalleled Efficiency: Cradle’s platform dramatically reduces the time and resources traditionally required for protein development. By leveraging AI’s ability to comprehend complex amino acid sequences, scientists can bypass the arduous trial-and-error process and generate promising protein candidates with greater efficiency. 

Enhanced Collaboration: Cradle’s unique approach positions Artificial Intelligence as the interpreter of the “alien programming language” of proteins. With Cradle’s platform as the mediator, researchers can seamlessly exchange ideas, iterate on designs, and make data-driven decisions based on AI-generated protein variants. 

Targeted Protein Functionalities: The ability to specify precise protein functionalities is crucial in various industries, including pharmaceuticals, food production, and industrial applications. By leveraging AI’s data analysis capabilities, researchers can identify proteins with the desired properties more efficiently and accurately. This targeted approach opens up new possibilities for the development of therapeutics, sustainable food solutions, and environmentally friendly industrial processes.

Versatility and Innovation: Cradle is not limited to a single area of focus. This versatility showcases the broad applications of Cradle’s platform and its potential to revolutionize multiple industries. By pushing the boundaries of protein design and constantly exploring new avenues, Cradle remains at the forefront of innovation, driving scientific advancements and addressing pressing challenges in various fields.

Cradle claims that its platform significantly reduces the time and number of experiments typically required for protein development. While specific details are limited, the company provides a compelling example involving the enhancement of T7 RNA polymerase stability. According to Cradle, their software generated variants with increased stability, surpassing traditional experimental methods. This showcases the immense potential of AI in protein design and highlights the impact that Cradle’s platform can have on various industries.

The versatility of Cradle’s platform is evident in the company’s diverse internal projects. From developing a dehalogenase for soil decontamination to creating a growth factor for cultured meat production, Cradle is actively engaged in pushing the boundaries of protein design. CEO Stef van Grieken emphasizes the platform’s effectiveness in accelerating research and development, not only in drug development but also in food and industrial applications. This versatility positions Cradle as a leader in the field, with the potential to revolutionize multiple industries.

While Cradle is based in Europe, the company faces both advantages and challenges in the region. Fundraising for deep-tech ventures can be more complex compared to the United States. However, van Grieken recognizes the untapped talent pool in Europe, particularly in cities like Zurich. With top-tier universities in computer science and molecular biology, as well as the presence of major tech and biotech companies, Europe’s ecosystem is rapidly evolving. Cradle’s success in securing funding, including a $5.5 million seed round last year and the recent $24 million funding round, demonstrates the confidence investors have in the company’s potential.

With the additional funding, Cradle plans to expand its team and sales efforts, further solidifying its position as a leader in AI-powered protein programming. The company’s vision of unlocking the future of protein design is becoming a reality, and the possibilities are endless. By leveraging AI to interpret and manipulate amino acid sequences, Cradle is empowering scientists and researchers to unlock the full potential of protein-based solutions. 



In a world where innovation is key, Cradle is at the forefront of revolutionizing protein design. With its AI-powered platform, the company is streamlining the protein development process, reducing time and costs, and opening up new possibilities for advancements in pharmaceuticals, food production, and industrial applications. Cradle’s success and the support it has garnered from major investors are a testament to the transformative potential of its technology.

As the world continues to recognize the importance of protein design and its impact on various industries, Cradle’s AI-powered platform is set to shape the future of biotech and AI. With its ambitious projects and dedication to pushing the boundaries of protein design, Cradle is poised to unlock new frontiers and revolutionize the way we approach protein-based solutions. The future of protein design is here, and Cradle is leading the way.
