About

I'm a senior marketing leader with seven years of experience across fintech, B2B SaaS, agency work, and fine art. I specialize in translating complex products into marketing programs that generate pipeline, accelerate sales cycles, and build brand authority. Right now I'm at Justt, a fintech company that uses AI to automate chargeback disputes, where I run marketing end-to-end as the primary lead across North America and EMEA.

I've built growth programs from scratch, owned seven-figure budgets, led go-to-market for product launches, and helped take a company from Series B through Series C. I'm equally comfortable setting strategy and being the one who executes it.

How I got here

I've always been drawn to understanding why people make the decisions they do. Curiosity is what got me into marketing. That curiosity about consumer psychology is what pulled me toward marketing, and once I found it, it clicked pretty quickly.

I spent my early career moving between industries, from real estate to fine art to agency work, picking up a different lens at each stop. That range turned out to be an asset. When I got to Justt and had the chance to build something from the ground up in a fast-moving fintech environment, I had a toolkit most people don't get from a straight line career path.

How I work

  • I think of marketing as a revenue function, not a support function. That means staying close to the sales team, being honest about what channels are earning their budget, and caring more about pipeline than impressions.
  • I like building programs that are repeatable and measurable, but I'm also comfortable operating in ambiguity. At a startup, you don't always have clean data or a playbook to follow. You make a call, you run the experiment, and you learn fast. I've gotten pretty good at that part.
  • I collaborate well across functions, and I take mentorship seriously. Some of the most useful work I've done has been helping other marketers on the team think through problems, not just solving them myself.

Outside of work

When I'm not working, you'll find me playing chess, deep in a book, on the golf course, watching Liverpool FC, or visiting a new coffee shop with my wife and our miniature dachshund Reese. I'm based in Stamford, CT, and I'm always discovering new music, tinkering with AI tools, and reading whatever Substack writers have caught my attention lately.
