Case Study: Sleek Achieves 3x More Qualified Leads with Respond.io

How Sleek Gained 3x More Qualified Leads over WhatsApp

Sleek, an all-in-one digital platform for startups and SMEs, needed a better way to handle sales inquiries and capture higher-quality leads. Its web chat setup was confusing for agents, slowed response times, and often produced fake contact details, so the company wanted to move customer conversations to WhatsApp with a more intuitive messaging platform. Respond.io provided the business messaging solution used to support this shift.

Respond.io onboarded Sleek’s agents across four countries, connected separate WhatsApp API accounts to private Workspaces for each market, and automated routing, FAQs, round-robin assignment, and away messages through Workflows. With respond.io, Sleek achieved 3.5x more sales inquiries, 3x more qualified leads, and a 68% NPS score, while agents were able to respond within 2 to 3 minutes.
