Experience evaluation

Two problems stood out:

  • Accessing support was hard.
  • Once users found it, the experience was overwhelming.

Solution

I ran a series of cross-functional workshops with Customer Support, ML Engineering, Content, and Product to align on two clear pillars the experience would be built around.

Pillar 1: Easy-to-follow answers

Structured step-by-step answer from Coinbase Support
Easy to scan explanation
Relevant actions
New responses were easier to understand

Pillar 2: Be available till the end

Support minimises for in-app flows

Pillar 3: Personalised support

Quick help cards available within support
Support available when user runs into restrictions or limitation on their account.

Visual design for all things A.I

A.I responses can take a few seconds to generate, and that wait starts to feel long when you're staring at a static screen. Instead of a plain spinner, we designed a branded loading animation that signals progress as the model thinks, and gives people something a little more interesting to look at than a boring circle.

Since then: Concierge for high-net-worth customers

Chat as a platform held up. The same foundation we built for mass-market support was extended to power Concierge, a premium, human-first chat experience for Coinbase One customers. End-to-end encrypted, personal, always-on.

Key learnings

A team is only as sharp as the goal it's pointed at. The hardest part of this project wasn't the craft. It was getting 4 orgs, 4 roadmaps, and dozens of people aligned on what "good" looked like. I also learned how much it matters to build trust with your peers' managers, not just your own. That's where the real leverage lives.
