01 The problem

Agents wanted automated texting, but replacing the CRM they already trusted was not realistic.

Follow Up Boss users needed automated texting and follow-up, but switching CRMs meant abandoning years of contacts, workflows, and team habits.

Follow Up Boss users lacked automated outbound texting.

Years of contacts and working habits made a platform migration risky.

The founder saw the gap but had no software engineering background.

02 How it was solved

A focused API integration added the missing capability without replacing the core CRM.

The first Make.com beta connected two open APIs. After validation, LeadEngage packaged two-way messaging, workflows, funnels, and a white-labeled HighLevel layer into three recurring tiers.
