Steering the Future: How Reticular is Redefining Protein Design for Pharma

In the ever-evolving world of biotechnology and pharmaceuticals, companies face the daunting challenge of designing drugs that can precisely target and affect specific biological functions. Despite the breakthrough technologies that have revolutionized drug discovery, like AlphaFold's protein structure prediction models, these tools still have limitations. They are often viewed as black boxes, producing results that are difficult to interpret and control. As a result, pharma companies frequently spend millions of dollars on experiments that fail to yield useful results. Enter Reticular, a groundbreaking startup with a bold vision to revolutionize protein design using artificial intelligence (AI) to make these models steerable and interpretable, much like how one can prompt large language models (LLMs) such as ChatGPT.

Founded in 2024 and based in San Francisco, Reticular has already begun to tackle some of the most pressing issues in drug discovery. With just a team of two founders, the company is working on pioneering AI models for protein design that are more accessible, interpretable, and precise than current offerings. Their aim is to help pharma companies harness the full potential of AI-driven protein modeling by providing tools that allow for more accurate predictions and more efficient exploration of biological data.

How Did Reticular Come to Be?

Reticular was founded by two brilliant minds, Nithin Parsan and John Yang, who share a deep passion for the intersection of artificial intelligence and biology. Their journey began long before the creation of the company. The two first met while competing in the International Biology Olympiads (IBO) and Neuroscience Olympiads, where they discovered their shared interest in biology and AI. After spending four years as roommates at MIT, where they both earned degrees in AI and bioengineering, they collaborated on research that was published in prestigious journals like NeurIPS, Nature, and PLoS ONE. Their academic backgrounds and achievements set the stage for what would become the foundation of Reticular.

Nithin, who previously led clinical machine learning projects at the MIT-IBM Watson AI Lab, is known for his work in applying AI to real-world biological problems. Meanwhile, John, a brilliant MIT AI and mathematics graduate, has made significant contributions to machine learning research, particularly in its application to biological systems. Their shared experiences in the academic and research world laid the groundwork for their understanding of the limitations and challenges facing the field of protein modeling.

Despite the impressive advances in AI-powered drug discovery tools, Nithin and John realized that something was missing: control. The ability to guide and manipulate AI models to generate biologically useful results in a reliable, interpretable manner was not fully realized. With this in mind, they launched Reticular to focus on the mechanics of making these models steerable and interpretable, enabling pharma companies to navigate the complexities of drug discovery without wasting resources on trial-and-error.

What Are the Main Challenges in Protein Design Today?

One of the biggest hurdles in the field of drug discovery is the scarcity of reliable data. While protein models like AlphaFold have made impressive strides in predicting protein structures, they still remain "black boxes" that output data without much insight into the underlying processes. Pharmaceutical companies often find themselves testing various AI-generated protein designs, only to discover that the results are not what they expected—or worse, lead to costly failures.

The scarcity of data and the high costs associated with validating AI-generated results are major pain points for the industry. With limited data to work with, it becomes increasingly difficult for companies to verify the accuracy of predictions made by AI models, leading to wasted resources and slow progress. In addition, the lack of control over these models means that companies cannot easily direct the models towards the specific outcomes they need. This leaves them reliant on a trial-and-error approach, where they have to sift through countless failed experiments before finding a promising solution.

Reticular aims to solve these issues by applying AI interpretability techniques to unlock the hidden information within protein models. By making AI models more understandable and manipulable, Reticular is changing the way companies approach protein design, enabling them to make faster, more informed decisions that lead to successful drug discoveries.

How Does Reticular's Approach Work?

Reticular is applying mechanistic interpretability techniques to steer AI models and extract meaningful knowledge from them, even in the face of limited data. This involves using sophisticated algorithms that can interpret and control the internal mechanisms of a protein model, rather than relying solely on trial-and-error or brute force experimentation.

The key innovation behind Reticular's approach is that it brings the concept of steerability—something already seen in AI models like Claude or ChatGPT—into the realm of protein modeling. Just as users can prompt an LLM to generate specific text responses, Reticular's technology allows scientists to "steer" protein models toward specific biological outcomes. For example, one of the company’s initial successes involved steering the Green Fluorescent Protein (GFP) towards more fluorescent sequences by controlling the model's internal knowledge.

By making protein models interpretable, Reticular is providing companies with the ability to understand the underlying biological features driving the results of the model. This interpretability is crucial for drug discovery, as it allows researchers to trust the AI's predictions and make decisions based on a clear understanding of how the model arrived at its conclusions.

What Are the Benefits of Reticular's Technology?

Reticular's technology offers a wide range of benefits for pharmaceutical and biotech companies looking to improve their drug discovery processes. By unlocking the hidden information in protein models and providing more control over the design process, Reticular is transforming the landscape of protein engineering. The primary benefits of Reticular's technology include:

1. Direct Steering of Protein Models

Reticular provides companies with the ability to directly steer protein models towards desired properties. This means that instead of relying on blind experimentation, companies can control the direction of the protein design process, ensuring more targeted and efficient outcomes.

2. Interpretable Biological Features

Every protein design generated by Reticular's AI models is backed by interpretable biological features, allowing researchers to understand why a particular design was generated and how it aligns with their goals. This transparency is crucial in reducing uncertainty and enabling better decision-making.

3. Efficient Exploration of Large Design Spaces

Protein design involves exploring vast combinatorial spaces, which can be overwhelming without the right tools. Reticular’s technology helps companies efficiently explore these spaces with limited data, accelerating the pace of discovery and reducing the time it takes to identify viable drug candidates.

4. Cost Savings

By making protein design more predictable and steering the models towards specific outcomes, Reticular helps companies save millions of dollars that would otherwise be spent on unsuccessful experiments. This not only increases the efficiency of the drug discovery process but also reduces the financial risks associated with it.

How is Reticular Scaling Its Impact?

Despite being a relatively young startup, Reticular is already making waves in the biotech and pharmaceutical industries. The company’s unique approach to protein modeling and AI interpretability has drawn the attention of early-stage biotech firms, who are excited to partner with Reticular to scale their drug discovery efforts. Just a week after its pivot, Reticular successfully identified the first interpretable features in protein models, a breakthrough that promises to revolutionize the field.

Reticular’s rapid growth is a testament to the effectiveness of its technology and the demand for more interpretable and steerable AI tools in the life sciences. The company is piloting its AI interpretability technology with key industry players and plans to expand its reach as more pharma companies realize the potential of AI-driven drug discovery solutions.
