What a fractional CMO does for a Belgian B2B company

A fractional CMO is a senior marketing leader who works part-time inside your leadership team. You get the judgement of an experienced CMO for a set number of days each week, and your team keeps doing the work. An interim CMO does the same job close to full-time, for a fixed period. From week one, Phil takes ownership of four things:

Market focus: which buyers, segments and accounts matter now, and which do not.
Message: one clear reason to buy, used by marketing and sales alike.
Sales alignment: one qualification standard, one hand-off and one weekly review.
Operating rhythm: a plan, a cadence and clear owners, so the team keeps moving after the mandate ends.

Who it is for

Belgian B2B companies with a technical product and a real sales team, typically 50 to 500 people, that have no senior marketing leader or whose marketing leader has just left. Phil focuses on:

Energy, energy engineering and cleantech companies selling complex solutions to businesses.
Technical B2B software and data companies, from scale-ups to PE-backed firms.
AI and data consultancies that need sharper positioning and a steady pipeline.
