When a Growing Company Needs a COO

A growing company needs a chief operating officer when execution has become the main constraint on growth: the founder spends most of their time coordinating departments, decisions queue up for one person, and good strategies stall in delivery. Hiring a COO before those signs appear adds cost; hiring long after them leaves the founder exhausted and the business stuck.

Six signs it is time

1. The founder is the router. Every cross-department issue ends up with the founder, and nothing moves while they are travelling.
2. Department heads compete rather than coordinate. Sales promises what operations cannot deliver, and finance hears about it last.
3. Strategy meetings produce plans that nobody tracks. Quarterly priorities are forgotten by the second month.
4. Growth has outpaced process. What worked at 40 people fails at 120: approvals, handoffs and reporting break down.
5. The founder wants to focus elsewhere. On customers, product, fundraising or the next business, and cannot.
6. Key metrics arrive late or conflict. Different departments report different numbers for the same thing.

What a COO should own

The role varies, but in founder-led companies it usually covers:

• The operating rhythm: weekly, monthly and quarterly reviews and their follow-through.
• Cross-department processes: order to delivery, hire to productive, enquiry to invoice.
• Operational metrics and reporting.
• Department heads for operations, delivery and often HR.
• Systems and tools that support how work gets done.

The founder typically keeps vision, key customers, capital and culture.

Internal promotion or external hire?

Promote internally when a senior manager already coordinates across departments, has the trust of peers, and understands the business deeply. Support them with coaching and clear authority.

Hire externally when the company needs experience of the next stage of scale that nobody inside has, or when internal candidates are too close to existing conflicts.

Either way, write down what the COO decides alone, what they decide with the founder, and what remains with the founder. Unclear authority is the most common reason COO hires fail.

The first 90 days for a new COO

A new COO earns authority by understanding before changing. A sensible sequence:

• Days 1 to 30: listen and map. Meet every department head and a sample of their teams. Follow two or three orders or projects end to end. Identify where work waits, where it is redone, and where information is missing.
• Days 31 to 60: fix the rhythm. Establish the weekly and monthly reviews, agree a small set of metrics per department, and start writing decisions down with owners and dates.
• Days 61 to 90: first visible wins. Remove two or three bottlenecks that everyone complains about. Often these are approval delays, unclear handoffs or reports that take days to assemble.

The founder's role in this period is to stay out of the way publicly while staying close privately: weekly one-to-ones, fast answers to questions of authority, and visible support when the COO makes an unpopular call.

Why systems matter as much as the person

A COO without information spends their first year chasing updates, as the founder did. Before or alongside the hire, invest in:

• A single source of truth for orders, projects and key metrics.
• Workflow tools that make handoffs visible.
• Dashboards that make the weekly review take minutes to prepare.

These let the COO manage by exception rather than by interrogation.

Alternatives when the time is not quite right

• A general manager with narrower scope, such as operations only.
• A fractional COO for two or three days a week.
• A structured operating rhythm and better systems, which sometimes remove the need for another senior hire for a year or two.

Frequently asked questions

At what size do companies usually hire a COO?

There is no fixed number, but the signs often appear between 60 and 150 employees, or when a company expands to several locations.

How do we measure a COO's success?

Agree three to five operational outcomes, such as on-time delivery, cycle time or margin, and review them quarterly.

Can a COO work if the founder still makes every decision?

No. The founder must hand over real authority, visibly, or the team will keep going around the COO.

Should the COO also own technology?

In many mid-sized companies, yes, until a dedicated technology leader is justified. A fractional CTO or trusted partner can support them.
