What Does a COO Do at a Founder-Led DTC Brand?

A COO at a founder-led DTC brand owns the operating system underneath the business: demand and supply planning, fulfillment and logistics, vendor and 3PL relationships, the systems that connect them, and the cash conversion cycle that determines how much of the brand's own growth it can actually fund. The CEO still sets direction. The COO makes sure the business can execute on it without the wheels coming off at $40M, $80M, or $150M in revenue.

That sounds close to what a VP of Operations does, and at a glance the job descriptions overlap. The difference at this stage isn't title depth, it's scope. A COO doesn't run one function well. They own how every function fits together, and they're the person a founder can hand an entire operating problem to and walk away from.

What day-to-day decisions does a COO actually own?

A COO's calendar is built around a handful of recurring decisions, not a single department. In practice, that means running the sales and operations planning (S&OP) cadence, the recurring meeting where demand forecasts, inventory positions, and supply commitments get reconciled, and having the authority to act on what it surfaces.

Here's how that ownership typically splits from what a founder or a functional lead still owns at the same brand:

That table is a simplification, the actual split shifts by brand. But it captures the pattern we see across the $35M–$400M range of consumer brands we work with: founders keep the "should we" questions, and a good COO owns the "how, and by when."

How is a COO's job different from a VP of Operations or Ops Director?

An Ops Director runs a function well. What a COO does is different: they're accountable for how all the functions add up to a working system, and for catching the failure that happens between departments, not inside one of them.

We've written before about brands moving from a single distribution center to a distributed fulfillment network. That's a good example of a COO-level call. A fulfillment manager can tell you the current DC is at capacity, and a logistics director can price out a second facility, but deciding whether the brand's growth curve actually justifies that capital commitment, and whether the systems and team can run two nodes instead of one, requires someone who's looking at demand planning, cash flow, and the org chart at the same time. That's the job.

The same pattern shows up in how DTC brands manage wholesale inventory differently from direct inventory. A demand planner can flag that one allocation model doesn't fit both channels. A COO is the one who decides to run two models, funds the systems change, and owns the outcome if it's wrong.

What does a COO do in the first 90 days at a DTC brand?

In the first 90 days, a COO's job is almost entirely diagnostic: mapping where the operation actually breaks, not fixing everything at once. That usually looks like three phases:

1. Weeks 1–4: Audit the system. Walk every function that touches product, demand planning, procurement, fulfillment, customer service, and find where handoffs break down. Most operational pain in a scaling DTC brand traces back to two or three chokepoints, not twenty.
2. Weeks 5–8: Fix the highest-cost break first. Usually inventory accuracy, a broken S&OP cadence, or a 3PL relationship that's quietly costing margin. This is where a COO earns trust: a visible, measurable fix before asking for a bigger mandate.
3. Weeks 9–12: Build the cadence. Stand up the recurring rhythm, weekly ops review, monthly S&OP, quarterly systems check, that keeps the fix from unraveling once attention moves elsewhere.

This is also where the founder relationship either works or doesn't. A COO who spends 90 days producing reports instead of resolving the two or three things actually costing the brand money hasn't done the job, regardless of how the reports look.

Fractional COO vs. full-time COO: what actually changes about the work?

The scope of the job doesn't change between fractional and full-time. The depth of day-to-day involvement does. A fractional COO typically works one or two days a week, focused on the highest-leverage decisions: the S&OP cadence, the fulfillment network strategy, the systems roadmap. A full-time COO is in the daily execution of that plan, running the team that carries it out.

Brands in the $35M–$150M range often start with fractional coverage: enough operator judgment to stop the bleeding and build the system, without the fixed cost of a full executive hire before the org is ready to support one. It's a different question from when to bring on COO-level help at all. We've covered that timing question separately in When Do You Need to Hire a COO? This is about what changes in the work itself once someone's in the seat, fractional or not.

What does great COO work actually look like?

It looks like fewer fires, not more dashboards. The clearest sign a COO is doing the job well isn't a stack of reports. It's that inventory turns improve, fulfillment costs per order drop, and the founder stops getting pulled into decisions that should never have reached their desk.

That's the standard we hold our own operators to in Scale-stage engagements. Izba brands that tighten this system typically see operational costs drop by roughly 25% and revenue grow by up to 30%, once the operating system stops fighting the growth plan instead of supporting it. We're not building a permanent org chart seat. We're building the system and cadence a brand can run without us once it's in place.

Demand for this kind of operator judgment isn't slowing down. Fractional executive hiring demand grew 149% year-over-year from Q1 2025 to Q1 2026, as more founder-led brands look for senior operating help before they're ready for a full executive hire.

What does a COO do, in one sentence?

If a founder only remembers one thing: a COO turns the operating decisions that would otherwise sit on the CEO's desk, inventory, fulfillment, vendors, systems, cash conversion, into a system that runs on its own cadence. Everything above is what that looks like in practice.

Quick answers

Does a COO replace a VP of Operations? No. A VP of Operations usually still exists under a COO, running a specific function (fulfillment, procurement, or customer ops). The COO owns how that function connects to every other one.

Is a fractional COO "enough," or does it need to be full-time? It depends on decision velocity, not brand size alone. If operational decisions are piling up faster than a one- or two-day-a-week cadence can clear them, that's the signal to move to full-time, not a specific revenue number.

What's the single clearest sign a brand needs COO-level ownership? The founder is the one still resolving inventory, fulfillment, or vendor issues day to day instead of setting direction. That's the operational load a COO exists to absorb.

Does a COO need deep expertise in every function they oversee? No, and trying to be the expert in every seat is a common mistake. The job is strategic integration across finance, supply chain, and customer service, not hands-on mastery of each one.
