The founder

Martin Cable,
founder of Simpleris

I have spent over 20 years working inside growing businesses where complexity outpaced control. Different sectors. The same pattern.

In manufacturing and engineering environments, I saw tribal knowledge, quality drift and long training cycles quietly create risk. In tech and scaling service businesses, the same risk showed up as founder dependency, unclear ownership and delivery becoming fragile as headcount grew.

As a Certified SYSTEMologist® and Lean Six Sigma practitioner, I bring proven methodologies together with a practical, real-world approach. But frameworks are never the focus. The focus is reducing operational risk so businesses can scale without relying on individuals to hold everything together.

The businesses I work with are typically 5 to 50 people: growing fast enough for the informal approach to be breaking down, but not yet large enough to have dedicated operational infrastructure. They are run by founders, CEOs and operations leaders who know something needs to change, but have not yet had a clear method for changing it.

That is what Simpleris is for.

How we work

What to expect from
working with Simpleris

🔍
Diagnosis before prescription
Every engagement starts with an Operational Risk Assessment. We surface what is actually happening before we recommend anything. The ORA is free, focused and leaves you with something useful whether or not we go further.
📊
Evidence-led, not opinion-led
Lean Six Sigma means changes are grounded in data. We measure before we change, and measure again after. Claims about improvement are backed by numbers, not impressions.
👥
Built with your team, not around them
The people who do the work know the work. We engage your team in the process of documenting and improving it. That is how the systems stick after we leave, rather than sitting unused in a folder.
🎯
Focused on what matters most
Not every process needs to be documented. We identify the critical few: the ones where risk is highest and the return on systemisation is greatest. Effort is directed where it makes the biggest difference.
⚡
Risk concentration, not coverage
Trying to fix everything creates more complexity, not more control. We look for the small number of workflows where failure would hurt most, the dependencies that create the greatest exposure, and the points where growth is adding pressure rather than capacity. Reducing risk in those areas delivers disproportionate impact. Everything else can wait.
🎯
Clarity over documentation
Operational risk is reduced when ownership is clear, handovers are explicit, and decisions don't rely on memory or heroics. Documentation is used only where it supports those outcomes. We avoid documenting for its own sake, creating systems no one uses, or adding tools before clarity exists. The goal is control, not complexity.
🏁
You should not need us on an ongoing basis
The goal of a Simpleris engagement is operational independence: a business that runs without needing external support. We hand over everything and structure the engagement so that what we build outlasts our involvement.
