The Fiduciary Problem in Fractional Leadership

If you’re hiring a fractional executive, you’re trusting an outsider with your strategy, your vulnerabilities, and your competitive position. Most people in this space don’t think hard enough about what that trust demands. I do - and here’s why.

The Vacuum Salesman

When I was a kid, a door-to-door vacuum salesman came to our house. He was persuasive and he was violent. He sold my mother a vacuum we couldn’t afford - one that turned out to be broken. He took the money and left us with a machine that didn’t work and a family that couldn’t buy food.

I don’t remember much about being that young. I remember that. I remember my mother skipping meals so her children could eat. I remember giving up my own dinner so my younger brother and my mother would have enough, and pretending I wasn’t hungry so they wouldn’t worry. I remember learning to plant seed potatoes and keeping a secret garden so we’d have food in the future, because I was so afraid of it happening again that I needed to build something - anything - that would make sure the people I loved wouldn’t go hungry.

That garden led to an interest in automation - building systems that could keep growing things even when I wasn’t there to tend them - which led to computers as soon as they were available to me. My dream from the start was to build systems that help people.

That experience shaped something in me that I’ve carried ever since. I learned that selling is predatory - that to sell something is to be a predator. I became an engineer because I was afraid that selling makes you a bad person, and I wanted to help people instead. Engineering felt like the opposite of what that salesman did. He took. I wanted to build systems that kept people safe.

I’m being honest about this because it matters for what comes next. That belief - that selling is inherently unethical - isn’t entirely rational. I know that. But it comes from watching my family go hungry because a man with a quota cared more about his commission than whether we could eat. That’s not an abstraction for me. It’s the reason I think about fiduciary duty the way I do, and it’s the reason the fractional leadership model deserves more ethical scrutiny than it typically gets.

The Problem Nobody Talks About

Fractional leadership is growing because it makes economic sense. Not every company needs a full-time CTO or VP of Engineering. Hiring one part-time gives you senior strategic guidance at a fraction of the cost. The arrangement works. But it creates an ethical tension that most people in this space either don’t see or choose to ignore.

When you serve as a fractional executive, multiple organizations trust you with their technical strategy, their architectural vulnerabilities, their competitive positioning, and their internal problems. You sit in their leadership meetings. You see their roadmaps. You understand where they’re weak.

Now imagine you serve two companies in adjacent markets. Company A tells you they’re pivoting into a space that Company B already occupies. You know Company B’s architecture can’t handle the competitive pressure. What do you do with that?

Most fractional CTOs never think about this. They take clients based on who pays, not on whether the engagements create conflicts. They rationalize it by telling themselves they’d never consciously share information between clients. But the problem isn’t conscious disclosure - it’s that your judgment is contaminated. You can’t unknow what you know, and you can’t prevent that knowledge from shaping the advice you give.

What Fiduciary Duty Actually Means

Fiduciary duty is a legal concept from finance and law, but the principle applies anywhere someone trusts you with their interests. It means you put the client’s interests ahead of your own. It means you don’t take positions that create conflicts between the people who trust you. It means when there’s a tension between what’s good for you and what’s good for them, they win.

In fractional leadership, this means:

You don’t serve competing organizations. Not “direct competitors” in the narrow legal sense - organizations whose interests could conflict in ways that compromise your judgment. If knowing Client A’s strategy would change the advice you give Client B, those engagements are incompatible.

You scope engagements clearly. Each client knows exactly what they’re getting, what you’re responsible for, and what falls outside the engagement. No ambiguity about where your obligations start and stop.

You maintain information barriers. What you learn inside one engagement stays inside that engagement. This isn’t just about not forwarding emails - it’s about disciplining your own thinking so that insights from one client don’t leak into recommendations for another.

You operate in the same legal jurisdiction as your clients. Fractional leadership means access to trade secrets, competitive strategy, and sometimes regulated data. That access carries compliance obligations - export control, data residency, regulatory frameworks like ITAR and HIPAA - that only work when the executive is subject to the same legal system as the organization they serve.

When your fractional CTO operates from a different country, you have no practical enforcement mechanism if something goes wrong. No domestic court order. No aligned regulatory framework. No shared legal accountability. Compliance isn’t optional, and it doesn’t survive a jurisdictional gap.

I’ve shipped compliant systems under FDA, FIPS, HIPAA, and ITAR requirements - this isn’t theoretical for me. I’m a US citizen, born in the US, operating under US law - which means the organizations I serve don’t carry work authorization risk, export control ambiguity, or jurisdictional gaps in their fractional leadership.

You turn down money when the engagement doesn’t pass the test. This is the one that separates people who actually care about fiduciary duty from people who just talk about it. If a prospective client creates a conflict with an existing one, you say no. Even if you need the income.

Why This Matters More Than People Think

The fractional model is built on trust. A company hiring a fractional CTO is giving a part-time outsider access to information that full-time employees spend years earning the right to see. They’re doing it because they believe your expertise justifies the risk.

When a fractional executive takes on conflicting engagements, or fails to think rigorously about where conflicts might emerge, they’re exploiting that trust. They’re taking something from someone who extended them good faith. The scale is different from a broken vacuum, but the mechanism is the same - someone with leverage extracting value from someone who trusted them.

I don’t think most people in fractional roles are malicious. I think they’re careless. They don’t have a framework for thinking about these obligations because the industry doesn’t demand one. There’s no fractional executive licensing board. There’s no fiduciary standard. There’s just the market, and the market rewards volume.

What I Actually Do About It

I take contract and fractional engagements when the scope justifies it. When I do, I apply these principles:

• I evaluate potential conflicts before signing anything. If there’s a conflict with an existing engagement, I decline.
• I define clear boundaries around what information belongs to which engagement.
• I document the scope so both sides know exactly what they’re paying for and what falls outside.
• I limit the number of concurrent engagements so I can actually give each one the attention it deserves - not stack clients like a billable-hour machine.

This costs me money. Turning down work because of a potential conflict is expensive. Limiting my client count when I could theoretically handle more is leaving revenue on the table. But the alternative is becoming the vacuum salesman - someone who takes from people who trust him because the money matters more than the obligation.

I watched what that does to a family. I’m not doing it to someone else’s company.

There’s a flip side to this that’s worth stating plainly: when I commit to your organization, I’m not also helping your competitors. The organizations that don’t have me on their side are now competing against the full weight of someone who is exclusively on yours. I don’t split my loyalty and I don’t hedge my bets. If I’m solving your problem, I’m solving your problem - and I will outwork and outbuild whoever is on the other side of it.

If you’re evaluating fractional technical leadership for your organization, I’d rather have the conversation about conflicts and boundaries upfront than pretend they don’t exist. Let’s talk.

Disclaimer: I write about fiduciary principles from the perspective of engineering leadership, not as legal counsel. I took law courses through Running Start but didn’t complete the degree - the program wouldn’t cover the full cost and I couldn’t afford the rest. Nothing in this essay constitutes legal advice.
