Andrew G. Hargreave III  ·  Fractional CTO  ·  agh3 IT Services

Your technology decisions shouldn’t land on your desk.

I step in as your Fractional CTO — owning the roadmap, managing vendors, and turning technology complexity into business clarity.

Does this sound familiar?

Your business has outgrown its level of technology leadership.

These are the signs. If more than one rings true, you need a senior technical leader in the room.

  • Technology decisions keep piling up on the CEO’s desk with no one to own them
  • IT vendors or your MSP are operating without clear direction or accountability
  • Infrastructure has grown organically for years with no clear strategy
  • An ERP or critical system change is on the horizon with no technical leader to drive it
  • Security risks are accumulating and nobody has full visibility into the exposure
What is a Fractional CTO?

Not a consultant who delivers a deck and leaves.

A Fractional CTO is a part-time, embedded member of your leadership team. They attend your meetings, manage your vendors and technical staff, own the technology roadmap, and are accountable for outcomes — just like a full-time CTO, at a fraction of the cost and commitment.

Many growing businesses reach a point where technology complexity is real but a full-time hire isn’t the right answer yet. A Fractional CTO fills that gap with senior leadership that’s immediately productive and aligned to your business goals.

How I help

Senior technology leadership across three areas

Strategic Advisory

Technology strategy & roadmap

I translate your business goals into a technology direction. Technology decisions get off your desk and onto a clear roadmap. Board-level communication, IT investment evaluation, and 3–5 year planning.

Vendor & Team Oversight

Vendor and team accountability

MSPs and IT vendors need direction and accountability to perform. I manage those relationships, evaluate performance, guide internal staff, and ensure your technology partners are actually serving your business.

Infrastructure Foundation

Deep technical execution

Decades of hands-on infrastructure work means I can go deep when needed. Virtualization, Microsoft 365 & identity, networking, backup and DR — I’ve built and recovered these systems under real pressure.

Why this practice exists

The gap I kept seeing

Over three decades inside enterprise IT, I watched the same pattern play out in growing businesses: technology complexity outpaced leadership capacity. Systems grew fragile. Vendors drifted. Good people made uninformed decisions because nobody with the right experience was in the room.

I built this practice to give SMBs access to the same caliber of senior technology leadership that larger organizations take for granted — without the overhead of a full-time hire. agh3 IT Services grew from decades of hands-on consulting into a focused Fractional CTO practice because that’s where the real need is.
