What a Fractional CTO Does in the First 30-60-90 Days

For many CEOs, working with a Fractional CTO is a new experience. The title sounds senior, the mandate sounds broad, and it is not always obvious what this person will actually do in the first weeks. You do not want another abstract advisor, and you definitely do not want a long consulting engagement that produces a thick slide deck and no visible change.

A good Fractional CTO knows that the first 90 days are about earning trust, removing uncertainty, and creating momentum. That usually happens in three concrete phases:

A quick health check and orientation
Stabilizing what you already have
Accelerating where it makes business sense

Each phase has clear deliverables, clear conversations with you as CEO, and clear outcomes your team can feel.

The first 30 days: quick health check and orientation

The first month is about understanding your world fast, without paralyzing the team with interviews and workshops. The Fractional CTO is trying to answer three questions: what you are actually trying to achieve as a business in the next 12 to 18 months, what shape your technology is in today, and where the few risks or constraints are that could derail those plans.

In practice, that usually looks like:

A short kickoff with you and one or two key leaders to understand strategy, revenue model, sales motion, and any non-negotiable commitments you have made to customers or investors.
A few focused sessions with engineers, product, and operations to hear how things really work day to day. These are not performance reviews; they are reality checks.
A targeted review of systems and tools, covering your main product, critical integrations, production environment, and the way you track work and incidents.

A useful way to think about this phase is: the Fractional CTO is trying to build a mental “flight simulator” of your business. If they pull on one lever (for example, reduce scope or change a vendor), they want to be able to predict roughly what breaks and who needs to be involved.

Typical outputs in this phase include:

A simple architecture map that shows how the main systems, data stores, and integrations fit together, in language a CEO can understand. Good maps usually include which parts are revenue critical, which parts are legacy, and which vendors are in the loop.
A risk register with a small number of items that could meaningfully hurt revenue, resilience, or reputation if left alone. A good register has columns like description, impact, likelihood, owner, and time frame, not just a vague list of worries.
A concise note on delivery and team health, describing how work flows from idea to production, how releases behave under stress, and where people are stretched too thin or acting as single points of failure.

The tone matters. A good Fractional CTO will make it explicit that this is about helping the existing team succeed, not about proving anyone wrong. In many companies, the internal engineers already know where the bodies are buried, but they are too busy shipping, do not have the mandate to push back, or feel conflicted raising hard truths. An external CTO can often say the same things your people would say, but with enough distance and authority that the message lands.

By the end of the first 30 days, you as CEO should be able to answer questions like where you are carrying unacceptable risk, what the two or three biggest constraints on speed are, and how far your current architecture is from what you will need if the business grows as planned. You do not have to like the answers yet, you just need them to be clear.

Days 30 to 60: stabilizing the system

Once there is a shared picture of reality, the focus shifts from diagnosis to stabilization. The goal in this phase is not to redesign everything, it is to stop avoidable pain, protect the business from obvious risk, and create a foundation where work can move more predictably.

A lot of the work sits in three areas that interact with each other.

1. Delivery and operating rhythm The Fractional CTO sets up a lightweight cadence so that work enters, moves, and exits the system in a consistent way. That might mean shifting to shorter planning cycles, enforcing smaller batches of work, and making sure each cycle ends with a real demo of working software, not just status updates. The point is that Sales, Customer Success, and Marketing know when they can expect changes and what is actually coming, instead of living in a state of permanent “maybe.”

Behind the scenes, this often involves small but powerful changes: agreeing on who can add work mid-cycle and under what conditions, reducing the number of different boards and tools where requests appear, and putting a simple rule in place about how many items any team can actively work on at once.

2. Risk reduction moves From the initial risk register, a few items will be too serious to leave alone. Examples include lack of tested backups, no monitoring around a core payment or onboarding flow, or a deployment pipeline that regularly causes outages. The Fractional CTO will work with your team to select a small number of high impact fixes that can be delivered in this 30 day window and materially reduce your exposure.

Useful patterns here are very concrete. For example, run a restore test from backup and document how long it took and what failed, put basic alerts around the three most important user journeys, or change the release process so that every deployment has an obvious rollback path. These are the kinds of changes that do not impress people on slides, but save you from ugly moments with customers.

3. Clarifying responsibilities and escalation paths Stability is not just technical, it is organizational. The Fractional CTO will help you make clear who owns what: who has the final say on technical tradeoffs, who decides what goes into a release, who is responsible when incidents happen, and how decisions are made when Product, Sales, and Engineering disagree. Often this does not require a full reorg; it might be as simple as redefining a few roles, writing down a short escalation ladder, and agreeing on how leaders talk about tradeoffs in front of the teams.

You should start to see visible wins in this phase. Releases feel a bit less stressful, incident response feels less improvised, and conversations about priorities are slightly more grounded. Engineers feel that there is at least a plan for reducing pain instead of endlessly tolerating it, and other departments feel that someone is finally speaking both “business” and “engineering” in the same sentence.

Days 60 to 90: accelerating with intent

Once the system is no longer on fire every week, the Fractional CTO can shift attention to acceleration. This is where technology, product, and strategy start to line up in a disciplined way.

Two tracks are usually running in parallel.

On one track, the CTO is working with you and your product or business leaders to design a 3 to 6 month roadmap that is realistic, sequenced, and directly tied to the outcomes you care about. That roadmap includes not just features, but also the technical work required to support them: refactors, platform upgrades, and infrastructure changes that will prevent you from hitting a wall later. A good roadmap will explicitly call out what you are not going to do in the next 6 months, so that teams are not pulled in ten directions at once.

On the other track, they are shaping the people and structure needed to deliver that roadmap. This does not automatically mean hiring a large team. In many cases it means pausing certain hires, changing the profile of roles you are recruiting for, or reorganizing existing people around customer outcomes rather than technical layers.

Often the Fractional CTO will provide a short, written hiring plan that covers which roles to hire, in what order, and why, along with a brief view of expected impact. They may also propose a small change in team topology, for example creating a cross functional squad around a key product area instead of slicing work horizontally by "front end" and "back end". Vendor relationships are part of this picture as well: deciding which agency contracts still make sense, where you should bring knowledge in house, and where you need to tighten expectations on quality and ownership.

Throughout this period, the Fractional CTO is also introducing simple metrics so that you can see progress, such as average time from commitment to production for important work, number of incidents per month and time to recovery, or the percentage of work that gets carried over between cycles. You do not need a fancy dashboard; you need a small set of numbers that let you and your CTO have a grounded conversation every few weeks.

By the end of day 90, you should have a clear understanding of your architecture and its main risks, a more stable delivery system that can ship predictably, and a 3 to 6 month roadmap and hiring plan that you actually believe in. More importantly, you should feel that technology is once again supporting the business narrative you tell to customers, partners, and the board.

How to work with a Fractional CTO so you get real value

The first 90 days are not only about what the Fractional CTO does, they are also about how you as CEO engage with them. A strong partner can still be wasted if the engagement is set up poorly.

There are a few practical things that make a huge difference.

Give them direct access to reality. That means access to your main systems, your key people, and at least some unfiltered data, not just curated updates. If the CTO has to learn everything through PowerPoint, you are paying for theater, not insight.

Block time for three key conversations on your own calendar at the start: one around day 10 to 15 to hear the early hypotheses, one around day 30 to review the first health check and risk register, and one around day 75 to lock in the next 90 day plan. Treat those sessions as working meetings where decisions get made, not status updates you can half attend.

Be explicit about constraints. If you know you cannot hire more people this quarter, say so. If you are locked into a major vendor for contractual reasons, make that clear. Fractional CTOs do their best work when they are optimizing within real boundaries, not imagining an ideal world that you cannot afford.

Finally, ask for artifacts you can reuse. An architecture map you can show to future hires and vendors, a risk register that feeds into your regular exec meetings, a roadmap that ties into budget planning, and a short set of metrics you will look at together every month. These are the things that make the work survive beyond the person.

Avoiding consultant theater

CEOs are rightly skeptical of experts who ask many questions, run many workshops, and leave behind an impressive slide deck but little else. A Fractional CTO engagement has to avoid this pattern to be worth your time.

In a healthy engagement, you will notice that the Fractional CTO spends meaningful time with your actual systems and people, not just with templates and frameworks. When they talk about risk or opportunity, they refer to specific behaviors in your product, your infrastructure, and your team, not generic best practices. They are comfortable pointing out where you are already strong, as well as where you are exposed, and they do not treat every problem as an excuse to expand scope.

The deliverables should feel like working tools. You should find yourself reusing the architecture map in a sales conversation when a prospect asks how integration works, or bringing the risk register into a board meeting to explain where you are investing. Your leadership team should be referring to the 3 to 6 month roadmap when they make decisions about marketing campaigns, hiring sequences, or which customers to prioritize.

And there should be an end to the first phase. The 30-60-90 structure is there so that you and the Fractional CTO can step back and decide what happens next: whether to extend, narrow the focus, hand over to an internal leader, or declare the mission accomplished for now. The goal of the first 90 days is to leave you with more clarity and more control, not with a new permanent dependency.

What you should expect to feel as CEO

By the end of a well run 30-60-90 day Fractional CTO engagement, you should not feel that every problem is solved, but you should feel two very practical things.

First, you should feel oriented. You know where your technology stands, what is dangerous, what is merely ugly, and what can wait. You can explain it to your board or to a potential acquirer without hand waving, using the same architecture map, risk register, and metrics that your CTO uses internally.

Second, you should feel in motion. There is a concrete 90 day plan that your existing team is already executing, with a short list of visible changes you can look for: a safer release process, one or two retired sources of technical debt, a clearer roadmap, or a leadership structure that makes more sense to everyone involved. You know what success looks like for this first phase, and you know when you will sit down to decide what comes next.

That is what a Fractional CTO is doing in the first 30-60-90 days: not magic, not theater, but the disciplined work of turning technology from a vague worry into a system you can actually lead and improve.
