Growth, creativity and trust: the B2B story of Cannes Lions 2026 — Trust & Influence in B2B

In this special edition of Trust & Influence in B2B, Joel Harrison is joined by Fiona McKenzie of Marketbridge to make sense of Cannes Lions 2026. Fresh from five days of multi-stream content, installations and fringe events, they let the dust settle and distil what actually matters for B2B marketers – viewed through a growth lens, not creativity for its own sake.

They unpack why B2B is visibly on the rise at Cannes, the tension between creativity and commercial measurement, and the CFO buy-in conversation (brand as future cashflow). They dig into three important releases from the week: the FT's work on trust (including the finding that 82% trust a source more when it challenges than when it agrees), Bloomberg on reputation pulling weight across the full funnel, and Bain & Co.'s new model positioned as a rival to NPS, scoring a buyer's likelihood to choose you before any deal is on the table.

The conversation moves through the B2B Lions winner – an obscure Swedish ball-bearing company using tidal energy in the Faroe Islands, and why a big idea told as a wider go-to-market story is a step in the right direction – the rise of creators and influence in B2B, Joel's framework of five "trust champions," and a notably optimistic read on AI: a technology that surfaces existing misalignment and removes grunt work rather than replacing human judgment. They close on what Cannes could do better for the B2B community.

In this episode:

What Cannes actually is, and why it's so hard to navigate. B2B moving up the agenda. The growth-versus-creativity lens. CFO buy-in and brand as future cashflow. Why CMOs are exhausted by the measurement debate. Three key releases: FT on trust, Bloomberg on reputation, Bain's NPS rival. The B2B Lions winner and what it signals. Creators, influence and Joel's five trust champions. A grounded, optimistic take on AI. What's missing, and what would take Cannes to the next level in 2027.
