GEAR UP
As your company scales, complexity multiplies:
- Collaborating with large enterprise clients requires mature processes.
- Internal operations buckle under team growth.
- Cross-functional alignment is missing.
- Founders are pulled into firefighting instead of strategy.
As an on-demand COO, I bring order to operational growth using structural principles proven in corporations and adapted to the speed and dynamics of startups.
I manage complex enterprise projects, build scalable processes, set up cross-functional teams, and ensure executional reliability.

My approach combines startup speed with enterprise-grade discipline.
Delaying structure at this stage is risky. Execution gaps grow fast and lost time can't be recovered. The right systems, now, mean avoiding costly detours later.
FIT CHECK
My services deliver the most value when:
You’re working with or preparing for large strategic clients.
Your teams (Product, Sales, Engineering, Delivery) lack coordination.
You need to scale but internal risks slow you down.
Stakeholders expect structured, professional execution.
OPERATOR
With 15+ years of leadership experience across startups, corporates, and SaaS businesses, including BMW, Deutsche Bahn, and mobility scaleups I help fast-growing startups move from firefighting to focused execution and I speak the language of startups and of corporates.
From agile transformations to Objective Key Results (OKR) implementation and org design, I turn strategic goals into measurable outcomes - fast. I hold a Ph.D. in Computational Engineering and certifications in Operation Management, AI & Change Leadership - enabling me to simplify complexity and drive execution across teams. As a TEDx speaker and German Innovation Award winner, I bring hands-on leadership, operational clarity and immediate impact to every engagement.

"I work with a select number of founders at a time to deliver deep operational transformations. Availability is limited to ensure personalized, high-impact leadership.
Let's build your startup’s future today — before scaling chaos sets in."
— Dr.-Ing. Joffrey Mabuma

Joffrey combines strong conceptual thinking with clear structure, hands-on leadership, and a motivating presence. He brings clarity and focus to complex situations and is someone teams naturally trust and rally behind. I highly recommend Joffrey as a sharp, reliable operator who adds real value, especially when things need to move forward with pace and direction.”
