The Challenge
Tanzim had built a compelling AI agent offer for client acquisition but struggled to get it in front of the right decision-makers. Without a repeatable outbound process, growth was inconsistent and hard to forecast.
Our Approach
We designed and deployed a multi-step cold email system targeting high-intent prospects in Tanzim's ideal customer profile. After booking 7 calls in the first week, we spent 2 weeks testing and optimizing - refining copy, ICP targeting, and follow-up sequences - until the system was producing 56 booked calls in a single week.
