The challenge

Our client was hosting a B2B event and had never run a dedicated social campaign for one like it. It needed a strategy that would drive registration and keep engagement going before, during, and after the event.

Three separate brands were taking part, each with its own audience and voice. The campaign had to serve all three while still feeling like one event.

What we did

Trellist created a first-of-its-type social media strategy and campaign and ran it from planning through wrap-up.

  • A strategy for each brand. We built event strategies for three separate brands, each combining organic, paid, and boosted content.
  • On the ground for all three days. Trellist attended the 3-day event, captured content, and posted live to all social channels.
  • Organic and paid working together. The campaign ran 315 organic posts alongside 52 ads, so reach never depended on a single tactic.
  • Lessons for next time. We delivered wrap-up reporting with data insights and recommendations for the next B2B event.
