We see the future in cells

An AI-first biotechnology company on a mission to cure chronic diseases

CellVoyant is an AI-first biotechnology company with a mission to create novel stem cell-based therapies for chronic diseases. Our technology uses AI-first live cell imaging to predict and optimise stem cell differentiation, to controllably manufacture any cell and tissue in the body at scale.

We’re working at the exciting intersection of cell biology, computer vision, engineering, and machine learning to industrialise next-generation science from research into the real world.

Our Mission

We have the best investors behind us from day 1. We’re backed by venture capital firms who were the earliest investors in AI pioneer DeepMind, the two leading AI-first drug discovery companies, Exscientia and Recursion, and self-driving challenger Wayve. We’re also supported by the founder/CEO of Abcam, which pioneered the antibody business.

What if we could make the best possible cells for a given patient and their condition consistently, robustly and predictively?

At CellVoyant we are pioneering novel platform technologies to manufacture stem-cell based cell therapies that are robust, controllable, efficient and safe.

Why does this matter? Today’s approach to stem cell differentiation is artisanal, slow and inefficient. The industry measures the start and end states of tissues, flying blind as to the real time dynamics of cell fate decisions, which results in suboptimal tissue manufacturing protocols at best. With hundreds of clinical trials ongoing and upcoming, we need a better way to deliver effective life-changing therapies to patients.

At CellVoyant, we’re combining large-scale cell culture and live cell imaging with data-driven computer vision to predict and optimise cell fate decisions in real-time. This approach allows us to uncover and control optimal routes for programming stem cells into any desired adult cell type.

Our Values


Our biggest asset is our people and building a team with a strong foundation has been a priority since day 1. We believe in strong company ownership via equity for all employees.


We fundamentally believe that “biology is living its AI moment”. You’ll have the opportunity to solve problems across cell biology, machine learning and engineering that do not have a textbook answer.

Creative Freedom

We pride ourselves on being bold, ambitious and creative. We offer freedom to achieve our mission in the most effective way. We dare you to question the status quo, challenge you to problem solve and empower you to succeed.


We value diverse perspectives and backgrounds, encourage creativity and open mindedness, and harness our differences to think outside of the box. Creating impact together is what drives us.

Be part of the journey

We seamlessly merge lab-based experimental biology with computing. We run a hybrid working setup with a lab and separate office based in Bristol, UK. Our wet lab scientists are based out of Bristol and our computational team are both based in Bristol and remote. We run off-sites quarterly to bring everyone together.
