Stuart Frost on Causal AI – Reimagining Industrial Intelligence Through Cause-Driven Decision-Making
Updated: Nov 26, 2025
Stuart Frost is a central voice in one of today’s most influential shifts in industrial transformation as Causal AI gains momentum across industries. The CEO of Geminos, Frost has shaped the trajectory of this emerging field more directly than almost any other leader.
He is known for founding and scaling more than 30 technology companies, including DATAllegro, which Microsoft acquired for $275 million, and has spent his multi-decade career at the forefront of data management, analytics, and industrial IoT since the earliest era of enterprise digitization.
Today, Frost is focused on solving one of the most persistent problems in industrial AI by addressing the staggering 87% failure rate of AI initiatives, due largely to the limitations of correlation-based modeling. Frost believes Causal AI is the answer.
At Geminos, an industry leader in AI solutions, he is building a next-generation platform that combines causal reasoning, large language models, and knowledge graphs to deliver clarity where conventional ML often falls short.
Frost discusses his journey into Causal AI, the turning points that shaped his entrepreneurial approach, and why this technology is poised to become the new foundation for industrial decision-making.
Q&A with Stuart Frost on causal AI
Describe how you got into the business of Causal AI.
Stuart Frost: I founded a number of AI startups in the 2010s that targeted industrial decision-making. It was very difficult to get consistent results that stood the test of time. This problem has been highlighted by IBM's finding that 87% of industrial AI projects fail. That simply isn't good enough.
I set out to solve this problem, and in founding Geminos, I quickly realized that the core problem is that traditional AI is based on correlations. Hence, I started to research the field of Causal AI and came across the work by Prof. Judea Pearl at UCLA. That led us to deciding to build a comprehensive, end-to-end platform to bring the power of Causal AI to industrial decision-making.
Looking back on the last five years, what has been the highlight of your career?
Stuart Frost: Seeing the light go on with major customers has been incredibly rewarding. There’s a distinct moment when they realize the limitations of traditional machine learning and deep learning models, when they see firsthand how Causal AI fundamentally changes the way they approach data-driven decision-making.
Once you've started using Causal AI, there's no going back. It’s simply a more effective, transparent, and scalable way to build AI-driven systems. The most gratifying part is hearing from customers who now rely on Causal AI as an essential tool in their operations.
How do you think your background has impacted the success of Geminos?
Stuart Frost: Having founded over 30 startups and run four of them as CEO, I'm what you might call a seasoned entrepreneur. A key tenet I've learned is to focus on customer success, rather than investor-driven milestones such as raising the next round of funding.
If your customers love your product, everything else will work out just fine. I’m also less focused on being a pure product company these days. It’s important to be flexible and deliver a solution customers can adopt successfully, even if that means providing more consulting.
How do you incorporate new strategies and tactics at Geminos?
Stuart Frost: A big part of my job is continually refining and expanding the product vision. That vision can’t be developed in isolation. It has to be shaped by real-world challenges. I make it a priority to engage directly with customers, understanding their pain points and workflows.
These conversations provide insights that drive our innovation strategy and ensure our solutions remain practical, adaptable, and impactful.
Describe a few accomplishments you are most proud of.
Stuart Frost: One of my proudest achievements is building a company culture that attracts and retains top talent. Many employees have chosen to work with me repeatedly over the years, sometimes for more than three decades. Creating an environment where people feel valued and excited to come to work has always been a priority.
Beyond that, I take great pride in the success of the startups I’ve founded, not just financially, but in the real-world impact they’ve delivered.
What motivates you to keep doing what you do?
Stuart Frost: Addiction! I’m hooked on the challenge of identifying complex customer problems and leading a team to solve them in ways that haven’t been done before. Seeing an idea evolve into a solution that drives measurable impact is incredibly satisfying.
Every time we help a company unlock new efficiencies or improve decision-making, it fuels my passion to push further.
What’s ahead for your next endeavor?
Stuart Frost: I'm 100% focused on Geminos.
Anything you are currently working on that you’d like to share?
Stuart Frost: Our major initiative right now is blending Causal AI with LLMs to create a Causal Knowledge Graph (CKG) that captures and shares information across large enterprises. Earlier technologies weren’t good enough, but now we can deliver on that vision.
We draw a parallel with Daniel Kahneman's Thinking, Fast and Slow: the LLM + CKG combination acts as “fast” thinking, while Causal AI handles the “slow” thinking necessary for mission-critical decisions.
