Product Marketing Manager · AI-Enabled GTM for B2B SaaS

Esme Fong

Product Marketing Manager
Building and running AI-enabled GTM systems for B2B SaaS.

I build the operating layer the marketing function runs on, positioning, messaging, ideal customer profile (ICP), product launches, lifecycle, and market prioritization, then run the GTM engineering that turns it into shipped work. Twelve pieces across four channels in twenty-four hours, week one at Atrium, three brands as a solo PMM running AI-enabled go-to-market. The system has run every week since.

Where It Started

Same instinct, four contexts.
Build the operating layer first, then run it.

Enterprise IT systems at Chevron, fintech infrastructure at ProBit, AI-enabled go-to-market at Atrium. Across all three, the work was building the operating layer first, then running what it produces at scale.

Database, ERP, and SOX-compliance systems that ran across analytics teams in three regions. SQL automation cut refresh time 57%.

A four-segment campaign tailored to each lapsed-cohort segment's actual blocker. The audience already existed. The work was naming the blocker before the message.

342% DAU, 7.4× ROI across 10 markets

A weighted ranking framework that selected 10 markets from 40, then tiered budget by performance. The framework was good at identifying priorities. I would now also stage investment within them.

About Esme

A PMM who builds the operating layer, then runs it at scale.

The instinct came before crypto, before AI. The pattern started at Chevron, where I built database and enterprise systems that ran across analytics teams in three regions. It carried into ProBit, a global web3 exchange, where I built the business analytics layer before leading a 15-person marketing team through product launches, lifecycle programs, and competitive positioning across staking, launchpads, and fiat ramps. It runs through Atrium now, where I built an AI-enabled PMM operating system across three brands. It has shipped every piece of work since.

At Atrium, I run AI workflow infrastructure that powers brand voice, ICP research, channel playbooks, and content QA across three brands. At ProBit, I scaled trading volume 50% during a bear market with zero incremental budget and grew DAU 342% by finding markets competitors ignored.

Currently open to full-time Product Marketing Manager roles at scaling AI-native and B2B SaaS companies. If you are building either and want a PMM who builds the operating layer and runs it at scale, get in touch.
