The Challenge

Breaking the one-purchase cycle in premium innerwear

bummer had built a cult following with its premium, personality-driven innerwear. But despite strong first-purchase numbers, a significant portion of customers simply never came back. Without proactive post-purchase engagement, the brand was leaving enormous revenue on the table.

Cart abandonment was equally costly. Customers who showed strong purchase intent — adding items, reaching checkout — were dropping off without completing their orders. Manual follow-ups weren't scalable, and email open rates had plateaued.

bummer needed a way to engage customers where they actually were: WhatsApp. But building intelligent, personalised conversational flows required technology and resources the team simply didn't have.

High one-time buyer rate

Most customers made a single purchase and never returned, creating unsustainable acquisition-led growth.

Cart abandonment at scale

Significant revenue was lost to customers who reached checkout but didn't complete their purchase.

Flat email engagement

Traditional re-engagement channels had hit a ceiling — the brand needed a higher-intent medium.

The Solution

Conversational commerce on WhatsApp, powered by AI

PrimeAssist AI transformed bummer's WhatsApp channel into an always-on revenue engine, combining smart automation with the brand's signature bold tone of voice.

Smart Cart Recovery

Personalised WhatsApp messages triggered at the perfect moment — reminding customers of their cart, offering gentle nudges, and making checkout frictionless from within the chat.

Loyalty & Re-engagement Flows

AI-driven sequences re-engaged lapsed buyers with personalised product recommendations, exclusive offers, and brand storytelling that matched bummer's distinct personality.

Post-Purchase Nurture

Every customer received a thoughtful post-purchase journey — from delivery updates to care tips, review requests, and timely cross-sell recommendations — all automated and on-brand.

The Results

From one-time buyers to loyal brand advocates
