There is no single COO. There is the co-founder who builds the operation from scratch, and there is the scaling executive who systematizes what already works. In sectors like fintech, insurtech, or healthtech, there is a third version: a co-architect who must combine operational muscle with regulatory fluency from day one. Unlike the CFO or the CTO, the COO role is not standardized; it is built specifically to complement what the CEO brings and complete what is missing. That is precisely what makes it so powerful - and so easy to get wrong.

A great COO is often invisible by design. When operations run well, nobody notices. When they don’t, everyone blames the culture or the product. This invisibility is the role's greatest strength, but it is also the reason founders consistently under-prioritize it. Because the role isn't a "plug-and-play" position, hiring the wrong profile at the right moment (or the right profile at the wrong moment) is one of the most expensive mistakes a founder can make.

The co-founder COO thrives in full ambiguity. They build from zero without a playbook, and in regulated sectors, they own the complex infrastructure that allows the product to even exist. For these companies, operational complexity isn't a scaling problem - it’s a launch condition. You cannot build a financial platform or a health service without someone who owns the compliance and operational plumbing from the start. In this context, the COO isn't a support function; they are a co-architect of the business model itself.

The dynamic shifts when a scaling COO enters the picture. This profile usually arrives once the operation is up and running, tasked with turning raw growth into a repeatable system. This is where the friction often lies. As an outsider - and frequently the first person to introduce formal structure- the scaling COO can be perceived as the person who "kills the agility" that the original team views as their secret sauce. They are often the first diverse profile in a founding team, and their mandate to create order is by design a threat to the productive chaos of the early days.

Knowing when to bridge this gap is the ultimate founder's test. You may need one when you find yourself solving daily operational fires instead of building the business, raising capital, or refining the product. You certainly need one when the team grows to the point where the CEO has more than five direct reports, or when new hires join only to find that no one has the time or the process to onboard them.

However, hiring well is only half the job. A COO needs real access to information, a clear mandate, and a founder who is psychologically ready to let go of certain territories. Without that, even the best profile in the world will fail. The COO is not a luxury; it is the difference between a company that scales and one that simply grows into chaos. Assuming that you’re delegating what used to be key parts of your job is the most strategic (and most underestimated) decision a founder will make. The conversation of what and when is the second. Take for granted that this is the person you’re going to talk to more than anyone else in the world for a long time!
