Mario Meyer

What the work has looked like

  • Range across industries

    Built and scaled SaaS platforms, marketplaces, and enterprise systems across a handful of industries — long enough to learn the right answer is rarely the same answer twice.

  • AI that earns its keep

    Put AI, automation, and cloud-native architecture to work where they actually earn their keep — embedded in how a business runs, not bolted on for the headline.

  • One source of truth

    Took startups from a tangle of disconnected tools to a single source of truth, and right-sized the architecture to fit the business they actually have — not the one a vendor wishes they had.

  • Skin in the game

    Held long-running fractional-CTO engagements — the kind where you stay long enough to live with your own decisions, and be judged on them.

Recent clients have included

  • Health/Wellness SaaS
  • Learning/Marketing Agency
  • B2B Logistics SaaS
  • Daycare Marketplace App
  • Brainstorming SaaS

What people keep saying

The clearest proof I can offer is not a metric. It is that the people I have worked with keep saying so, in their own names. My biggest contract closed in days, not months, on a single referral — earned trust doing what cold outreach cannot. There are more than forty recommendations like these on my LinkedIn; here are a few.
