Where I've done this
Humantic AI Clueso (YC W23) Attentive.ai
01 · What I do

Making customer success predictable, and account growth deliberate.

At Humantic AI I own a mid-market and enterprise book. Since joining, production adoption is up 63% and key accounts have expanded 1.5 to 2 times, quarter over quarter, because the onboarding, health-scoring and expansion playbooks now exist and the team runs on them.

Before that I did the same thing twice: at Clueso, standing up the CS function underneath a $1.2M ARR book, and at Attentive.ai, taking a 44% chunk of daily manual work out of the process for a US and Canada customer base.

01

Onboarding that reaches value on schedule

Multi-stakeholder rollouts on a defined path, with the same process holding whether the customer is one team or twelve.

02

Risk you can see before the renewal call

Product usage instrumented into a health score across the full book, so an account is flagged while there is still runway to fix it.

03

Expansion argued from the customer's own data

Growth cases built from usage evidence and taken to the economic buyer, not the day-to-day contact.

+63%

Production adoption lift on the current book.

1.5–2×

Enterprise account expansion, every quarter.
