Koen is an adviser, and a very specific one: positioning, new business and pricing your thinking, for agencies that already have a team. His trajectories start with a benchmark against around eighty comparable agencies and end in business decisions, with implementation help if you want it.

Best for agencies between five and a hundred people whose pipeline depends on referrals. His own test: the fee has to pay back ten times within two years. Not for a studio of three.

Marieke works on premium positioning: turning a founder whose clients want them personally into a company that owns its own category. She learned it the hard way, running a branding agency that worked for good names while she felt stuck between too many directions.

Best for agency founders whose reputation sells but whose company does not yet. Her method is in her book Onvergelijkbaar, which is a cheap way to test the fit before you book her. Full disclosure: Chris Out has co-coached many of her clients inside her programmes.

Agency Engines calls itself the agency for agencies. Bert leads positioning and growth; partners cover sales and M&A, PR and coaching, and operations. It is closer to consultancy than to coaching, and it works with the whole management team rather than the founder alone.

Best for established agencies with a leadership team that needs a sharper position and a plan. Less suited to a founder of a five-person studio looking for a weekly sparring partner.

IKAg is the reference for agency advice in Belgium: pitches, positioning, operations, M&A and mediation, with public prices for each format. Bart built and sold one of the country’s best-known digital agencies before switching sides.

Best for owners with a specific question who want a seasoned consultant on it. You book him per format.
