Case Study: Bummer achieves 7X increase in ROI with WebEngage

Shark Tank-Funded Bummer Sees a 7X Increase in ROI with WebEngage

Bummer is a D2C innerwear brand (founded 2020, Ahmedabad) known for sustainable, comfortable MicroModal underwear for India’s digital millennials. The company struggled with fragmented marketing tools, limited personalization, and an over-reliance on costly WhatsApp outreach—challenges that hindered unified segmentation, omnichannel growth, and retention.

Joining the WebEngage Startup Program, Bummer implemented live segmentation, Journey Designer, analytics and automated email/SMS/WhatsApp campaigns to personalize customer journeys and unify channels. The result: profitable campaigns with 5–7x ROI, repeat revenue rising from ~20% to 32–37% (>80% uplift), SMS accounting for 77% of revenue, email open rates of 40–60%, conversion rates improving from ~9% to 15–18%, and M0 retention increasing from 28% to 44%.
