Break free from trial and error.
Build predictable Customer Growth.
I help leaders of growth-stage B2B SaaS companies design and implement scalable Customer Success practices that drive Net Revenue Retention — from diagnosis to execution.
Why GTM execution breaks once sales outpaces post-sales.
Early stage is about learning to land customers. Growth is about learning to keep and grow them.
If leaders don’t embrace this shift with intent, GTM execution becomes unbalanced — acquisition-heavy and delivery-light — producing one-off transactions instead of predictable subscriptions.
With post-sales stuck in DIY and reactive firefighting, new revenue erodes faster than it can expand, showing up in clear symptoms.
Churn & Reduction
Losing customers and ARR faster than you can react.
Post-sales chaos
Customer Success falls to everyone — or no one.
Flat accounts
Account growth stays opportunistic or untapped.
Unguided customers
Resources spent on firefighting instead of leading to success.
No economies of scale
More customers, higher cost, zero efficiency.
Negative Customer ROI
Customer lifetime value doesn’t cover acquisition costs.
The Recurring Revenue Flywheel
Most growth challenges in the scale-up stage come from the very hand-crafted ways that once fueled your early success.
They got you here — but they’ll likely stop you from getting there.
To sustain growth, your business needs to evolve across these three dimensions:
Predictable Outcomes
You consistently deliver measurable value that support your customers’ willingness to grow with you.
- Do you know what Success truly means for your customers — in their own terms?
- Have you defined how you and your customers measure success together?
- Is there a proven, repeatable path your customers can follow to achieve success over and over again?
- Are you intentionally guiding customers along that path, not just reacting to their needs?
Repeatable Processes
Your operating model is structured, with clear accountability and repeatable processes that scale.
-
Do your customers experience a predefined engagement ownership throughout their journey?
-
Can you consistently identify early signs of risk before they impact renewals?
-
Is your renewal motion woven into the DNA or dependent on individual effort?
-
Are you systematically uncovering and progressing expansion opportunities across teams?
Expandable system
Your business runs on a “growth formula” letting it expand with customer and market needs.
-
Is your Customer Success model designed to adapt as your business and customer base evolve?
-
Do you know which customers deserve which level of focus and coverage — and why?
-
Are your engagement motions repeatable and adapted to customer value and desired outcomes?
-
Is your cost of service linked to the value it creates ?

About Me
Bjoern Stamm, MD of cooplio GmbH – LinkedIn
Since the mid-1990s, I’ve been helping customers succeed in the software world — from writing code to leading Customer Success organizations.
I started out developing custom software on my own and later with Accenture. At SAP, I shifted into business consulting and account leadership, managing global clients across Europe and the U.S., before moving to Singapore to lead a Professional Services division for the APJ region.
During Salesforce’s hyper-growth years, I learned what it truly means to put customers at the center. As a Senior Director Customer Success, I built and led teams managing portfolios of more than $100M and experienced firsthand how strong customer partnerships fuel sustainable growth.
At MuleSoft, I built regional Customer Success organizations from the ground up and later led a global overhaul of the company’s Customer Success strategy. After that, as Head of Customer Success at the fast-growing unicorn Tractable, I helped further mature the Customer Success function during a critical scaling phase.
Today, I bring this blend of operational and strategic experience into the scale-up world. I work with founders, executives, and investors to strengthen their customer base systematically — turning it into the #1 growth engine and reducing dependency on new business.
My motto: Don’t just treat the symptoms, fix the cause.
