The Fractional CTO Playbook: The First 30 Days

Fractional leadership only works if you create disproportionate value in limited time. A founder bringing in a part-time CTO doesn't want a slow ramp and a strategy deck in month three. They want the handful of decisions that de-risk the business, fast. Here's how I spend the first thirty days.

Week one: listen and inventory

Before changing anything, I map what exists — the stack, the team, the deploy story, the things that scare people. I talk to every engineer and the founder separately. The goal isn't judgment yet; it's an honest picture of where the risk and the leverage actually sit. Most founders are surprised by what surfaces.

Week two: stop the most expensive bleed

There's almost always one thing quietly costing the business — a deploy process that blocks releases, a cloud bill nobody's read, a single point of failure one person carries in their head. I fix or de-risk the most expensive one first. It buys credibility and breathing room in equal measure.

Week three: the decisions only a CTO makes

Build vs buy. Hire now vs later, and for what. Which technical debt to pay down and which to live with. Whether the architecture survives the next 10x or needs reshaping now. These are the calls founders lose sleep over because they lack the context to make them confidently. Making them well is the whole value of the role.

Week four: leave a system, not a dependency

The failure mode of fractional leadership is becoming the new single point of failure. So I write the decisions down, set the standards, and make sure the team can keep moving without me in every meeting. A good fractional CTO makes themselves progressively less necessary — that's the product.

The shape of the engagement

A day or two a week, aimed squarely at the decisions and the leadership, with the team doing the building. Founders don't need more hands on keyboards. They need someone who's made these calls before to make them again, calmly, with them.
