About us

Operators, not observers.

Coherex Advisory is a cooperative of senior leaders who have run the P&L, carried the pager and defended the plan to the board. We take on mandates as principals — with skin in the game and a date on the calendar for handover.

The bar

A small circle, held to a high standard.

Membership is earned, not applied for. Every operator has led transformation inside a real organisation — usually more than one — and can point to outcomes that outlasted them.

We keep the group deliberately small. Enough range to staff a mandate in days. Small enough that every member knows every engagement and can be called on to challenge it.

Focus

  • Corporate strategy
  • Commercial transformation
  • Board & executive advisory
  • Interim CEO / CCO

Rinze has spent his career at the intersection of strategy and execution — as executive, board advisor and value-creation lead across professional services, industrial and PE-backed portfolios. He steps into mandates where the direction is contested, the commercial engine is misfiring, or a new chapter needs to be written with the leadership team, not for them.

His signature is quiet clarity. Cut through the noise, name the two or three decisions that actually matter, and align the room behind them. Then stay close enough to the work to make sure the decisions survive contact with reality.

Focus

  • Post-merger integration
  • Operational turnaround
  • PE value creation
  • Interim CEO / COO / CTO

Ben has spent two decades inside the machine — as operator, CTO and transformation lead across financial services, industrial tech and scale-ups. He joins mandates where the strategy is set but execution is stalling: fragmented teams, competing roadmaps, a board that wants proof of progress by next quarter.

His approach is unfashionably direct. Diagnose the real constraint in weeks, not months. Rewire the operating rhythm. Stay in the seat until the organisation can run it without him. No deck theatre, no permanent dependency.

Nynke Rodenhuis

Focus

  • Programme & change management
  • Organisation design
  • Governance & stakeholder alignment
  • Interim programme director

Nynke works where strategy meets the organisation: complex, multi-stakeholder programmes inside international and public-facing institutions. As consultant and programme manager she has led change agendas in demanding, fast-moving environments — the kind where progress depends less on the plan and more on whether the right questions get asked early.

That is her trademark. Ask the questions others avoid, set expectations honestly, then deliver against them. She builds the governance, rhythm and coalition a transformation needs to hold once the advisors leave the room.

Jos Strijbosch

Partner — Commercial Growth & Go-to-Market

Focus

  • Go-to-market strategy
  • New business & sales engine design
  • Commercial due diligence
  • Interim CCO / Head of Business Development

Jos has spent three decades opening markets — as new-business hunter, business development lead and commercial advisor across B2B services, industrial tech, e-commerce and payments. He is called in when the proposition is sound but the revenue engine is not: a pipeline that stalls, a sales team carrying a process it cannot own, a growth plan without a route to the customer.

His view is fact-based and unsentimental. Map where the value actually sits, rebuild the commercial motion around it, and prove it with signed business before handing the engine over to the team that has to run it.
