Executive Assistant vs. Chief of Staff
A practical guide for founders and principals on when to hire each, how the two roles work together, and the sequence that actually holds up.

The most common confusion in early principal-office hiring is the difference between an executive assistant and a chief of staff. Founders read the title "chief of staff" in the press and assume it's the more senior version of an EA. It isn't. They are two different jobs, and hiring the wrong one, or hiring them in the wrong order, is one of the most expensive mistakes a founder or principal can make in their first two years of scaling private operations.
What each role actually is
An executive assistant owns the principal's time, calendar, communications, and coordination. The best senior EAs anticipate rather than react, protect the principal's attention across time zones and priorities, and hold the operating rhythm of a small team without being asked. In founder principal offices, they often bridge business and personal scope; in family offices, they typically work in close partnership with a personal assistant on private matters.
A chief of staff owns priorities, decisions, and cross-functional execution on the principal's behalf. They translate the principal's intent into execution across investments, board, household, and family operations, and they hold the operating cadence of the office so the principal's attention can be spent on the small number of things only they can do. The best chiefs of staff make fewer things reach the principal at all, they resolve, decide, delegate, and escalate on a clear framework.
Put simply: the EA owns the principal's time; the chief of staff owns the principal's decisions.
The sequence that actually works
Almost every founder or principal should hire a senior executive assistant first. The reason is structural, not philosophical: a chief of staff without a senior EA underneath them ends up doing calendar work and never gets to the priorities the role was hired for. And a founder without a senior EA cannot free up the time a chief of staff needs to operate on the principal's behalf.
The sequence we recommend:
- Stage 1. Hire a senior EA. This alone will absorb a meaningful amount of the coordination volume currently reaching the principal.
- Stage 2. Live with the senior EA for six to twelve months. Watch what still reaches you that shouldn't. The pattern that emerges tells you what the chief of staff mandate should actually be.
- Stage 3. Hire the chief of staff. The mandate is now specific to the decisions and priorities that are still landing on the principal, not a generic scope copied from another office.
When to skip Stage 1
There is one common exception: founders past a meaningful liquidity event who are simultaneously scaling business, investment, philanthropic, and household operations. In that scenario the office is being built from scratch and can absorb both hires at once, with the chief of staff shaping the EA search rather than the reverse. This is also the profile where a founder most often mistakes a senior EA for a chief of staff, because the EA they hire is genuinely doing chief-of-staff-adjacent work while the principal figures out what they actually need.
Compensation
Senior executive assistants in New York and the Bay Area typically earn $150,000 to $275,000 base plus discretionary bonus, with the top of the range going to EAs supporting founder principals or fund partners with meaningful personal scope. LA and Miami sit at similar levels; Chicago, Austin, and Seattle sit modestly below on base.
Chiefs of staff typically earn $225,000 to $425,000 base plus a discretionary annual bonus of 20 to 40 percent. Long-term incentives, carry participation in a direct investment vehicle, long-vesting cash bonuses, or founder-office equity, are standard in founder principal offices and increasingly common in family offices building for a five-to-ten-year horizon.
How the two roles work together
In a mature principal office, the EA and chief of staff function as a coordinated pair. The EA owns the principal's time and communications and reports either to the chief of staff or directly to the principal (structures vary). The chief of staff owns priorities and decisions, uses the EA to protect the principal's calendar for the work the principal actually needs to do, and holds the operating cadence of the office.
Neither role can succeed without the other. An EA without a chief of staff eventually gets pulled into decisions they are not paid to make. A chief of staff without an EA gets pulled into scheduling and never operates at the level the role was hired for.
Common mistakes
- Hiring a chief of staff first because the title sounds more strategic, then losing them to a peer principal within eighteen months because the role was miscast.
- Calling a senior EA a chief of staff at hiring time to make the compensation easier to justify, and then being unable to hire a real chief of staff a year later because the title is taken.
- Writing a job description instead of a written mandate for the chief of staff role, and losing the perimeter within six months.
- Under-compensating either role in year one and losing the hire in year two.
How Linear approaches it
Linear runs retained, confidential searches for senior executive assistants and chiefs of staff for founders, principals, and family offices across the country. We often help principals think through the sequence before a formal search begins, whether the right first hire is an EA, a chief of staff, or both, so the mandate matches the actual problem rather than the title on someone else's org chart.
If you are thinking about either role and want a private conversation before committing to a search, we are glad to help you think it through.
