Context

C4 Energy was extending the Ignite Your Fire platform into mental and cognitive performance with C4 Smart Energy. Kevin Hart was brought on as a brand ambassador because his real, multi-hyphenate lifestyle authentically embodied the product benefit. The opportunity was to broaden relevance beyond physical performance while protecting C4’s performance credibility.

Approach

I led the team to build “Get That Hart Smart Energy” as an integrated brand and acquisition campaign, not a celebrity moment. We grounded the work in Hart’s real routines, showing how C4 Smart Energy fuels focus across work, creativity, family, and business. The campaign launched with a collaborative hero film and was amplified through a large-scale media partnership with the LOL! Network across OTT and social, with product integrated into Hart-led programming such as Cold As Balls. In parallel, we developed retail-specific assets executed in-store to support secondary displays, expand distribution, and increase product velocity with key retail partners. Every execution reinforced a single idea: smarter energy for people who do more.

Results

The campaign expanded C4’s relevance into mental performance, driving strong engagement across digital and social channels and supporting sustained growth of C4 Smart Energy. Retail execution beat KPIs for incremental distribution and product velocity, accelerating sell-through with key partners. Hart’s authentic integration helped position the product as an everyday performance solution with cultural credibility.

Learnings

Brand ambassadors create impact when cultural storytelling, media, and retail execution work together to turn attention into belief and purchase.
