At MadFest last week, Rory Sutherland reminded the room what too many boardrooms forget: not everything valuable can be measured up front.

“Marketing should be treated like R&D, not procurement,” he said — urging brands to value discovery, not just efficiency.

His metaphor? Bees. Some follow a known path (performance), others go exploring (brand). Without the explorers, the hive starves.

While it’s a compelling argument in theory, the practical realities of brand-building can be tough for marketers. The biggest challenge? Proving it’s working. Without clear evidence of impact, securing budget for top-of-funnel campaigns can be next to impossible.

This tension echoed across sessions — but especially in our conversations with Fospha, who are helping brands tackle this head-on. Their new Glow research reveals how early indicators like branded search and engaged site visits serve as predictive signals of future revenue — giving marketers the proof they need to protect and scale brand investment.

At a time when finance demands certainty and marketing needs freedom, this might just be the measurement rethink the industry’s been waiting for.
