Bart Mroz

Hey, I'm Bart.

I build businesses, grow agencies, and help founders amplify their signal.

I spent 13 years building SUMO Heavy Industries from scratch to acquisition. Now I run Awesome Things XYZ, a holding company for the projects I'm building.

Email me, or find me on X, LinkedIn, Threads, or Bluesky.

Two decades of building, breaking, and figuring it out. From startups to acquisition.

Building what's next.
Growing what matters.
Amplifying what's worth hearing.

  1. 2026–Present

    Founder

    Awesome Things XYZ

    Holding company for multiple ventures. Current focus areas below.

  2. 2026–Present

    Fractional Growth Partner

    Agency Focus

    Fractional growth consulting for agencies and consultancies doing $1M–$10M. Dev shops, digital agencies, product studios. I work embedded with founders and leadership teams as a growth partner, not a vendor.

    Four tracks Operations & delivery, growth & BD engine, positioning & market presence, content strategy. Not theory. Playbooks I've already run for 20+ years.

  3. 2026–Present

    Content Amplification

    14:59 PM Studio

    Podcast production, daily distribution, thought leadership, and repurposing systems for founders who have strong signal but no time to broadcast it.

    Bottom Line Standalone or snaps into an Agency Focus engagement when a client is ready to build visibility.

  4. 2011–2023

    CEO & Founder

    SUMO Heavy Industries (Acquired)

    eCommerce and digital experience agency. Built from scratch over 13 years to acquisition. Clients included Pitney Bowes, Zoom, Roku, and Rogue Fitness.

    Bottom Line 800+ episodes of the eCommerce Minute podcast. Learned most of what I know by getting it wrong first and figuring it out second.

  • Intentionality over efficiency.
  • Own the outcome.
  • Make the invisible visible.
  • Finish with pride.
  • Serve people, not projects.

If you run an agency and growth feels like it's held together with duct tape, or you're a founder with something worth saying but no system to say it — that's what we do.
