Mabuma & Partners –

From Chaos to Clarity. Structure & Execute.

GEAR UP

Your Flexible COO Services for Business Growth
Clarity. Execution. Results. Without the Full-Time Cost.

You’re building something great. But scaling execution is harder than it looks.

As your business grows, so do the challenges:

  • Teams lose alignment

  • Operations become inefficient

  • Leadership capacity is stretched thin

  • Critical initiatives get delayed

  • You’re stuck in operations instead of driving strategy

Whether you’re a startup preparing to scale or an SME struggling with complexity, I provide the operational leadership you need, without hiring a full-time COO. 

I bring structure, team enablement, and execution leadership tailored to your current stage, so you can focus on growth, profitability, or stability.

Trusted by leading startups, SMEs, corporates & accelerators

FIT CHECK

Is This You?

I work with companies across Europe facing challenges like:


Your business is growing, but roles, responsibilities, and reporting lines are unclear, slowing execution and confusing your team.


Sales, operations, product, or service teams aren’t aligned. Information is siloed, workflows break down, and handovers are messy.


You're relying on informal tools, workarounds, or outdated systems, making it hard to grow without burning out your team.

Instead of focusing on growth or strategy, leadership is consumed by daily firefighting, putting key initiatives on hold.

“Working with Joffrey during the early phase of my drone delivery project was a great experience. He brought clarity to our outreach and customer interview strategy, helping us design a process that delivered measurable insights, not just vague feedback. What really stood out was his ability to quickly understand the business context and translate it into structured, actionable steps. His background across industries like mobility, automotive and tech brought a valuable perspective combining both strategic thinking and hands-on execution. Joffrey is very friendly and razor-sharp: a great person to collaborate with. I'd recommend him to any founder looking to bring structure, speed and focus to early-stage operations and growth.”

“I had the pleasure of working with Joffrey on a project for an automotive client, where we focused on improving customer operations. Joffrey quickly became a key driver, aligning our consulting team, internal sales, and client stakeholders to improve core processes that not only delivered immediate bottom-line impact, but also laid a solid foundation for scaling the contact center in the next phase of growth. 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.”

“Working with Joffrey as Head of was one of my highlights. In his role leading strategic client projects and leading a cross-functional team, he brought both structure and empathy to the table. His ability to align engineering, key account, and project management ensured we identified technical complexities early and handled client expectations transparently — both internally and externally. Joffrey doesn’t just manage operations — he builds bridges between teams, enabling real progress and execution. Our collaboration was always on equal footing, solution-oriented, and rooted in mutual respect.”

Joffrey was not only a strong strategic and operational partner—he brought structure, agility, and clarity to a complex environment. His approach was both analytical and human; he’s not just effective, but also a pleasure to work with.”
