Mario M.

Founder @ Reyem Tech — Fractional CTO leadership for Canadian SMEs | Tech strategy, AI & digital transformation

I moved from Brazil to Canada, and during COVID a single fractional CTO contract changed the course of my career. It showed me what the right technical leadership can do for a business that can't yet afford it full-time, and I built a company around that conviction.

Five years later, Reyem Tech is a firm of fractional CTOs helping growing Canadian businesses get their technology right without the cost of a full-time CTO. We deliver hands-on, CTO-level leadership across tech strategy, digital transformation, AI implementation, cloud architecture, and team building. What sets us apart is that we pair strategy with execution, so tech initiatives tie back to measurable business outcomes instead of stalling in a deck.

What that has looked like in practice:

  • Technical leadership inside 15+ companies
  • A core process cut from 10 minutes to 10 seconds
  • $2M+ in annual savings through contract renegotiation
  • Delivery cycles 50%+ faster across engagements
  • Near-zero turnover across 200+ remote staff
  • Government grant funding secured (DMAP, OCI)

We typically partner with manufacturing, healthcare, professional services, logistics, and SaaS companies, usually 10 to 200 employees and $1M to $50M in revenue.

Most partnerships start with a fixed-fee Technology Health Check: a fast, hands-on read on where your tech is helping and where it's quietly costing you, credited toward the engagement if you continue.

If your technology feels like a brake instead of a lever for growth, let's talk about a fractional CTO partnership that scales smarter.
