Fix the leaks in lead intake, follow-up, and handoff between marketing and sales.
Leads fall through the gap between marketing and sales more often than either side realises, usually because the handoff was never actually designed.
Map the full path from first contact to close, find where leads go quiet, and redesign the handoff so nothing depends on someone remembering to follow up.
A redesigned flow with clear ownership at each stage, plus a shortlist of what to automate next.
