Relationship manager co-pilot

Relationship managers were juggling dozens of customer relationships at once, each with its own history, paperwork and next step. I led the co-pilot piloted with 500 of them—and secured funding to scale to 5,000.

01 The problem

Relationship managers juggled dozens of customers while histories, goals and open items remained scattered across systems, emails and notes. Preparing one outreach took roughly thirty minutes. The opportunity was to assemble the context and draft a response without replacing the relationship manager's judgment.

I no longer have to open ten tabs to understand what happened with a customer, then spend fifteen minutes writing an outreach. The co-pilot does it in two minutes.

02 What I built

I led a cross-functional team of more than ten to build a prioritized day planner, customer-insight panel and reply-drafting workspace, then piloted it with 500 relationship managers. Each recommendation explains the signals behind it, and every message remains subject to human review.

03 Key decisions

Decision 01

Response confidence over suggestion frequency

Chose

Setting a response-confidence threshold so the co-pilot surfaced only higher-confidence recommendations, then letting relationship managers dismiss or rate them.

Over

Maximizing suggestion frequency by showing every possible trigger and asking relationship managers to separate meaningful opportunities from noise.

Because

The tradeoff produced a smaller set of credible recommendations, increasing suggestion acceptance by thirty percentage points while building greater user trust and adoption.

Decision 02

LLM-assisted priority over manual triage

Chose

A ranked queue in which the co-pilot weighs several customer signals, then explains both the recommendation and the evidence behind it.

Over

Asking each relationship manager to review every open relationship and decide whom to contact first using judgment alone.

Because

No single rule captured priority. The LLM combined several signals, while explanations made its reasoning inspectable. The tradeoff was inconsistent rankings and initial skepticism from relationship managers.

Decision 03

Draft-and-approve over fully automated replies

Chose

The co-pilot drafts a reply for the relationship manager to review and send; it never sends on its own.

Over

A genuinely considered version that sent AI-generated outreach without human review.

Because

Review protected accuracy and compliance, preserved relationship nuance and kept relationship managers in control—critical to adoption.

04 Outcome

A pilot with 500 relationship managers increased suggestion acceptance by thirty percentage points, while outreach preparation fell from roughly thirty minutes to under five. The business case projected $35M in benefits from greater customer-facing time and lower administrative costs, securing C-suite funding to scale to 5,000 relationship managers.

Next, I would start with fewer, higher-value triggers before expanding recommendations.
