I build Customer Success and post-sales into operating systems. Human led, AI assisted.

Fifteen years turning reactive, relationship-only functions into durable retention and expansion engines. Builder at heart, operator by trade, and increasingly a voice on where AI is taking all of this.

The Throughline

My career looks like a series of different titles. Underneath, it is the same job every time. Walk into something undefined or underperforming, find the structure hiding inside the chaos, and build the operating system that makes it work at scale. I learned to see people before process, which comes from a background in organizational psychology, and I learned to respect the numbers because the numbers are where trust is either earned or lost.

  1. 01

    Foundational Operations

    A background in organizational and industrial psychology. The lens that still shapes how I lead, why I think churn is almost always a human problem wearing a data costume, and why change management lives or dies on the people side.

  2. 02

    Financial Services

    Enterprise technology and operations work, including a release management role on the product that became Zelle, back when it was called Clear Exchange. An early lesson in shipping something real inside a large, complex organization.

  3. 03

    Apptio

    Took a single enterprise engagement and helped turn it into a productized offering that became a real part of the business. Became a field authority in technology business management and learned to connect technical adoption to the financial outcomes that executives actually care about.

  4. 04

    Advocate Networks

    A focused chapter in senior strategy and transformation consulting. Short in tenure, useful in lens, advising on operating model and transformation work before returning to building inside product companies.

  5. 05

    Sendbird

    Built Customer Success from the ground up. Stood up an enterprise-ready post-sales operating model where there had been none, and connected onboarding signals to risk and expansion.

  6. 06

    Aprimo

    Modernized a global post-sales operating model across onboarding, adoption, risk, renewals, expansion, and executive governance, with AI-assisted workflows layered into the operating cadence.

The pattern is zero to one. I bring clarity to chaos and structure to ambiguity, and I build the function that was not there before.

Things I Have Built

I do not just write about building. Here is some of it you can touch.

Internal Tool

AI-Assisted CSM Prep Assistant

A working session companion that turns account telemetry, notes, and signals into a ten-minute prep brief before every customer call.

Operating Model

Predictive Health-Score Redesign

Replaced gut-feel health with a weighted model that ties usage, sentiment, and executive engagement to renewal probability.

Cadence

Renewal-Readiness Operating Cadence

A 180-day rhythm that surfaces renewal risk and expansion lift early enough to actually do something about it.

Scaled CS

Digital Engagement And Scaled-Touch Motion

A pooled-CSM and in-product nudge model for the long tail, so high-touch teams stay focused on accounts that move the number.

Coming Soon

A Product Reveal In Progress

Something I have been quietly building for the post-sales operating layer. Name and details soon.

Advisory

I do selective advisory work under NorthSkye Advisory, focused on human-led, AI-assisted operating models for Customer Success and post-sales. My view is simple. AI should strengthen operating discipline, increase team capacity, sharpen decisions, and give people back the time to focus on customer outcomes. It should not be a replacement story. The best AI operating models codify what good looks like and make it easier for humans to do consistently.

Aprimo

Modernized a global post-sales operating model and layered AI-assisted workflows into the cadence. [Insert verified GRR/NRR and capacity result.]

Sendbird

Built Customer Success from nothing into an enterprise-ready operating model and connected onboarding telemetry to risk and expansion. [Insert verified GRR improvement.]

Apptio

Advised large enterprise accounts at the CIO, CFO, and CTO level and tied technical adoption to measurable financial impact. [Insert verified portfolio and influence figures.]
