A Montreal IT firm that can quote it, deploy it, secure it and support it.

AvantCIO was founded by a technology executive with more than twenty years running infrastructure for global firms, to give growing businesses and mid-size organizations the same quality of IT — and someone accountable for it.

What sets us apart

One accountable partner

Apple Technical Partner, Apple Authorized Reseller and member of the Microsoft AI Cloud Partner Program. We can supply the hardware, deploy the environment, secure it and support it, so there is no gap between the reseller and the consultant.

Senior from the first call

You work directly with the founder’s judgment, built over two decades leading technology in finance, gaming and industry. The same person who scopes the work answers for it.

Mac and Windows, equally

Most of our clients run both. We make a Mac a first-class citizen in a Microsoft 365 shop, and a Windows PC a well-behaved one in a Mac-first firm.

Rapid deployment

Startup speed, enterprise reliability. Your environment stood up and your people productive in weeks, not months.

Knowledge transfer

Your team learns to run and evolve every environment we build. No vendor dependency, no lock-in.

Honest assessments

Transparent recommendations, even when the right answer is “not yet” — or when it means walking away.

How we work

Everything we deploy — the computer, the sign-in, the apps, the security on the device and the support behind it — is designed and run as one environment, not bought as separate products. The discipline has a name in the industry, end user computing, and it is what the founder spent two decades doing for large organizations. For a growing business it shows up as fixed-scope offers: a review, a deployment, a pilot, an advisor on call. For a mid-size organization it becomes a program, run at scale, with a fractional CIO accountable for the result.

Fractional CIO leadership is how we deliver, not what we sell: the senior judgment arrives on day one, on a company-sized budget. AI has its place inside that story — Copilot where it earns its keep, AI on Mac where the data must stay — and never the other way round.

Who’s behind AvantCIO

Daniel Nerenberg — Founder

Daniel Nerenberg has led technology for more than twenty years across financial services, gaming, mining, energy, transportation and manufacturing, in roles ranging from global infrastructure at a major investment bank to Chief Information Officer, with experience spanning North America and Asia.

He founded AvantCIO in Montreal to bring that breadth to businesses without a full-time CIO: the ones making real decisions on security, compliance and AI, in the Mac-and-Windows environments most of them already run.
