Business Daily – Meet the Founders: The Tech Boss Who ‘X-rays’ Businesses
BBC World Service | April 9, 2026
Host: Will Bain | Guest: Alexander Rinker, Co-founder & Co-CEO of Celonis
Episode Overview
In this episode of Business Daily, host Will Bain sits down with Alexander Rinker, co-founder and co-CEO of Celonis, a software company revolutionizing the way organizations understand and improve their internal processes through process mining—a technology likened to 'x-raying' businesses. The conversation traces Celonis’s journey from a university project in Munich to a $13 billion global enterprise, exploring the challenges, risks, and strategies involved in scaling a tech company with deep roots in Europe, and discusses the future of process intelligence amid fast-evolving technology landscapes.
Key Discussion Points & Insights
The Light Bulb Moment and Early Beginnings
- Origins in Academia and Practice:
- Process mining started as a “purely academic field” and the founding team was exposed to it during university in Munich (03:45).
- Initial pilot for a local Munich radio station revealed how little businesses understood their own internal processes, leading to what Alexander describes as an “aha moment” for both the founders and their first clients (02:12, 08:15).
- Transforming Abstract Ideas into Action:
- The founders were inspired by the potential to use the digital footprints left in IT systems to map real business process flows, drawing an analogy to doctors using x-rays for more accurate diagnoses:
- “I like to call it an X-ray for businesses... It gives you an accurate picture of how the process works in reality, not how people imagine it works.” – Alexander Rinker (04:30)
What is Process Mining? How Does Celonis Work?
- Capturing Digital Traces:
- The software identifies objects and events within a business process (e.g. orders, shipments) and reconstructs the real workflow from data traces—no matter how many systems or manual steps are involved (05:35).
- Generates a dynamic, visual ‘traffic map’ of an organization’s processes, highlighting bottlenecks, delays, and inefficiencies.
- “We point out all this in a data driven way and you can very quickly go from a very high level view into every little detail.” – Alexander Rinker (06:47)
- Evolving into Process Intelligence:
- Celonis developed beyond analysis to real-time process monitoring and AI-triggered automations that can spot and correct issues without human initiation (07:12–07:45).
Early Challenges: Bootstrapping & Founding Team Dynamics
- Funding Struggles:
- Explained the lack of early investor interest and how the German entrepreneurial system requires significant upfront capital, unlike the US model:
- “We didn’t get any investor... People didn’t believe that those three young guys could start a B2B software business...So each founder [had] to put up $5,000.” – Alexander Rinker (08:15)
- Bootstrapping Reality:
- Reliance on revenue to fund growth created a stressful, “scrappy” but exciting environment.
- Importance of Co-founders and Relationship Maintenance:
- Open, “blunt conversations” and continual work on relationships critical to startup survival.
- “A lot of startups fail because the co-founders don’t get along... you really need to nurture [the relationship], for sure.” – Alexander Rinker (10:55)
Scaling Up: Entering the US and Global Ambitions
- Why Move to the US?:
- US as the largest market and business hub motivated the team's entry, with Alexander highlighting the difference in venture capital depth between the US and Europe (12:42).
- Discusses challenges for European startups seeking funding and the need for policy changes (like unlocking pension fund investment in innovation) to bolster European competition (13:17).
- “There’s a lot of smart people [in Europe], good universities, but certainly the capital infrastructure in the US is just amazing.” – Alexander Rinker (13:32)
- Key Milestones:
- Securing early big customers as proof of product-market fit was a pivotal moment for scaling (14:44).
The Role in the AI Revolution and Legacy IT Challenges
- AI Readiness & Constraints:
- Many companies’ web of outdated and fragmented IT systems hinders their ability to harness AI and automation effectively (16:05–16:58).
- Celonis’s platform provides the context and process data necessary for effective AI deployment in enterprise settings.
- Tangible Industry Impact:
- Their technology isn’t just for high-tech companies; even traditional sectors like brewing use it for supply chain optimization (e.g., Paulaner brewery at Oktoberfest) (17:06).
- “They even have an underground delivery system... and they’re optimizing that with Celonis.” – Alexander Rinker (17:20)
The Future: Adapting to Global Change and the Human Factor
- Staying Focused through Change:
- Emphasizes sticking to core strengths—making processes work for people, companies, and the planet—amid shifting tariffs, global supply chain disruptions, and the energy transition (18:10).
- Humans + Automation, not Humans vs. Automation:
- Warns against seeing process optimization as simply reducing staff; instead, sees it as a way to redeploy people to higher-value work:
- “I don’t believe that AI replaces what’s uniquely human...That actually gives an opportunity for companies to drive growth and play offense.” – Alexander Rinker (19:01).
- On Entrepreneurship and Partnership:
- “Oh, absolutely no way. I would have gone very far [without my co-founders].” – Alexander Rinker (19:42)
Notable Quotes & Memorable Moments
- On the first customer experience:
- "It was like an aha moment for them. They were like wow, we've never seen or looked at our business like this." – Alexander Rinker (02:12, 08:15)
- Analogy to medical x-rays:
- “When a doctor goes in and asks a patient what hurts...they also have an X-ray to get some data on what’s actually broken...that’s a very good analogy for our first product.” – Alexander Rinker (04:19)
- On European venture capital:
- “If you look at pensions, right, that's a huge portion of the wealth of a country. And in the US those pension funds are behind many of the large VCs. And I think Europe has to catch up.” – Alexander Rinker (13:32)
- Human relationships in startups:
- “It’s always work in progress...like every relationship.” – Alexander Rinker (10:55)
- On the future of work and automation:
- “If you engineer your company the right way, that actually allows you to grow and play offense and redeploy those people in other areas to do things that are uniquely human.” – Alexander Rinker (19:01)
- On the importance of his co-founders:
- "Oh, absolutely no way. I would have gone very far [without my co-founders]." – Alexander Rinker (19:42)
