Mario Meyer

Proof: results and what clients say

  • Range across industries

    Built and scaled SaaS platforms and marketplaces — but the range runs wider than software. A factory floor of a few hundred people. Several dozen oil-and-gas sites, from refineries to pipelines. Healthcare, professional services, and a national network of over two hundred people across more than two dozen teams. Wide enough to learn the right answer is rarely the same answer twice.

  • Regulated health data, handled right

    Led the technology handling protected health information at a regulated diagnostics company — across both the lab systems and the patient-facing platforms. Data stayed resident in Canada and the UK; lab staff worked on redacted records only, with no personal information exposed during analysis or reporting; every access was audit-logged; and any result shared with a family member or clinician stayed revocable by the patient at any time. Controls I can describe, not a compliance badge.

  • 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 recent example: replacing a costly single-seat rented tool with a data platform the whole company owns outright.

  • One source of truth

    Took startups and owner-led businesses from a tangle of disconnected tools to a single source of truth. For one consumer-products manufacturer that meant several separate online storefronts and a desktop accounting package with no ERP between them, pulled into one system that tracks inventory, warehouse locations, and manufacturing work orders — the ceiling that looked like a hiring problem, solved with one system. Always right-sized 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

  • Consumer-products manufacturer (digital transformation)
  • 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 — a client, the teams I led as their fractional CTO, and peers who have watched the work up close. 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.
