The eight hats

These answer to the board and to each other, not into a department. At the start one or two people hold all of them.

Product & design

Deciding what gets built and what it feels like to use. A startup's first product manager is usually the founder; the first designer rarely is.

Operations

Where people and delivery live. HR belongs here — hiring, onboarding, payroll, employment compliance and mobility are operational work with a legal edge — alongside turning a signed customer into a working one. The CHRO and the COO are the two hats above it.

Field & trade

The people who do the billable work and the people who organise them. In a trade business these are the first hires and the whole product — every other department on this page exists to keep them busy and paid.

Finance

Its own department, reporting to its own hat. The books, the cash, the payments rails and the audit — kept deliberately separate from whoever spends the money, because that separation is the cheapest control a company has.

Marketing & go-to-market

Two halves that are often confused. The brand half does creative, positioning, campaigns and the story the company tells outward and repeats inward — the CMO's work. The go-to-market half is partnering and growth: partnerships for reach, SDRs (BDRs outside the United States) for pipeline, and account management for what you already won. Between them sits RevOps, the plumbing that makes marketing, sales and finance count the same thing the same way.

Where these came from

Every record here is Part Owner's own writing. The departments and the job titles follow how funded companies actually staff up — the shape of a scaling org chart is not a secret, and the point of copying it is to show a founder what is coming rather than to reproduce anyone's postings. The field and trade roles are an addition of our own, because a trade business is mostly those and a software company has none of them. Titles name the base job: a seniority prefix — Senior, Sr., Staff — is a pay band rather than a different job, so it sits in the aliases rather than in the name.
