Your clients don't have a relationship
with your agency. They have one with Sarah.
Sarah knows the client hates stock photos, that the CEO reviews everything personally, and why the Q3 campaign shifted mid-flight. When Sarah leaves, that context leaves with her — and the client feels it immediately.
Sound familiar?
Account manager goes on leave
Nobody knows the client's brand voice, approval chain, or why they hate blue. Three weeks of re-learning.
Client playbook covers voice guidelines, stakeholder map, past decisions, and known landmines.
Senior creative quits
Years of client context — what works, what bombed, which stakeholder overrules the CMO — gone overnight.
Knowledge was captured in 10-minute interviews. New team member ramps in days, not months.
Scaling from 5 to 15 clients
Processes that lived in one person's head don't scale. Quality drops. Clients notice.
Every client has documented workflows, decision trees, and exception handling anyone can follow.
Client asks 'why did we do it that way?'
"Good question. I think Jake decided that before he left? Let me dig through old emails."
Decision history is in the playbook — rationale, alternatives considered, who approved.
How it works
Team member does a brain dump
Talk about how a client account runs — the real version, not the pitch deck version. Messy and unstructured is fine.
AI asks the smart follow-ups
Client preferences, approval workflows, edge cases, the 'oh and never do this' warnings that are critical but never documented.

Processes, stakeholder maps, decision trees, brand rules, and exception handling — structured so any team member can run the account.
Client retention starts with knowledge retention.
Agency turnover averages 30% per year. Every departure is a risk to client relationships. The usual fix — better project management tools — tracks what's happening but not why things are done a certain way.
Understudy captures the why — client preferences, historical context, relationship nuances, and process decisions that live in people's heads. It's the difference between a task list and institutional knowledge.
