The Challenge

Bloom Coffee's specialty roasts had a compelling story — single-origin beans, ethical sourcing, artisan roasting — but their marketing felt generic. Stock photography and template ads didn't communicate the brand's soul, leading to low engagement and stagnant subscription growth.

The Larven Solution

Larven AI helped Bloom build a narrative-driven creative system. Product photography was combined with AI-written origin stories, roast profiles, and sensory copy to produce ads that felt editorial. The platform's seasonal content calendar generated campaign themes around harvests, limited drops, and gift seasons automatically.

Results

Subscription revenue grew 340% in 6 months. Email click-through rates jumped 92% with AI-personalised subject lines and creative variants. Social following grew 55K as story-driven video content about sourcing journeys drove significant organic reach.

Our coffee deserved better marketing than we were giving it. Larven AI finally let us tell our story the way we always imagined it.
