Mason Brown
Marketing leader. Chicago, remote-first.

A marketer who ships.

I build marketing functions end to end, from brand through growth through enablement. I also build the AI tools that make the work possible.

Build

Tools I built to run marketing alone.

Two production web apps. Real infrastructure. The reason I can credibly say I run a marketing function alone.

Competitive Intelligence

An aggregator that does the work nobody was going to do.

Multi-API signal ingestion, Claude-powered synthesis, ready-to-use competitive briefings.

Content Recommendation

A recommendation engine grounded in a buyer journey I built myself.

Stakeholder, stage, and objection in. Ranked recommendations with reasoning out.

The work, in order

Three chapters. Same operator.

Scope widens, seat changes, the operator doesn't. Each chapter below is a number on a line I was accountable for.

  1. Chapter 01

    2020 – 2025

    Experts Exchange

    Five years running marketing at a 5M-user community.

    Inherited a dead list under 10% open rate. Eight months later, ByteSize sat at 200K subscribers, 60% open, $1.65M projected ARR. SEO overhaul across 71K URLs drove 135% traffic growth. Gamification system shipped end to end, PRD through GTM.

  2. Chapter 02

    2025 – present

    Fortune 10 Healthtech

    The first enterprise buyer intelligence program at a Fortune 10 healthtech company.

    300+ hours of primary audience interviews. A 76-slide persona library across four health system verticals. A 5-stage buyer journey architecture now powering their new-market expansion. Flew in to lead the sales training that rolled it out.

  3. Chapter 03

    2024 – present

    On the side

    Two production AI tools that make the solo claim credible.

    A competitive intelligence aggregator that runs on a schedule. A content recommendation engine grounded in a buyer journey I wrote. Real infrastructure, not prompt templates. The proof that one operator can run what used to take a team of five.
