(2026-01-15) A16z How To Hire A Chief Of Staff

A16z: How to hire a chief of staff. As you think about what a Chief of Staff (CoS) could help you accomplish at your startup, don’t assume you need one just because someone you know has one. “Chief of Staff” can sound like a flashy title to have on your team or in someone’s signature, but you need to be thoughtful about when, how, and why you bring one on.

Scope

Defining the role

First, a good CoS should complement you. The CoS should be strong where you are weak

A CoS is most effective when working under a single Executive, typically the founder or CEO.

To set expectations, a Chief of Staff is not:

• Only on “special projects”.
• An Executive or Personal Assistant.
• A substitute for a different functional leader,

A Chief of Staff is:

• Part of the executive team.
• A true generalist.
• Deeply trustworthy.

A strategic thought partner. They put their founder’s hat on and think like an owner. They understand the nuances of the business within their first 90 days.

Organizationally savvy. They can lead individual contributors (ICs) with ease and comfort. Typically a trained extrovert, they’re comfortable working solo and navigating complexity with ease.

The control tower. The CoS keeps the CEO focused, the team aligned, and the priorities moving. Without them, things fall apart.

Responsibilities

Here are responsibilities we’ve seen successful Chiefs of Staff take on:

• Establishing foundational systems that scale.
• Serving as connective tissue across teams.
• Providing air cover for the Executive.
• Leading special projects.
• Standing up company-wide goals and metrics.
• Filling in during an absence.

Because the scope of the role can vary, it’s important to clearly define the responsibilities your CoS will own. Doing this also makes it easier to measure their success in the role.

Don’t expect forever

In most cases, it’s a 2–3 year commitment.

The rationale behind this:

• They can use this role as a springboard into another part of the organization.
• Burnout is real. The intensity of the role makes it difficult to sustain long-term.
• As your company changes, the demands may shift and you may need a different CoS for a different stage.

What comes next

As for what comes next, a CoS who gravitates toward a particular functional area may go on to lead that organization. We’ve seen people step into leadership roles in Finance, Marketing, and Operations. They may also fit in well under a particular leader, such as your CRO or VP of Sales, to run Sales Ops.

If there’s not a strong internal fit at the two-year mark, start to consider how you can support them in their next step. They may want to be the CoS at a different startup or in a different industry.

Make it your own

Some leaders hesitate to use the more glamorous “Chief of Staff” title when hiring for the role. If that’s you, consider a job title that better fits your style or company culture, like Executive (or Chief) Business Partner, Special Assistant to the CEO, Office of the CEO, Director of Internal Ops, Head of Business Operations, or whatever new title you dream up.

Leveling the role

A well-leveled CoS ramps faster, focuses on the right areas, and delivers outsized value from the start. Since the CoS role is often short-term or designed to evolve, it’s especially important to align early on around what success looks like.

The three orientations

Depending on your company’s size, the CoS role typically falls into one of three core orientations: Executive, Leadership Team, or Organization. These aren’t strict phases—they often overlap—but they give you a clear way to evaluate where the CoS is adding value and where they might grow next.

Orientation 1: Small organization (20+ people)

They typically:

• Serve as a thought partner and advisor
• Help with communications, decks, and meeting preparation
• Act as a proxy when needed
• Track key priorities, decisions, and next steps

Orientation 2: Scaling organization (75+ people)

Focus areas usually include:

• Shaping the strategic agenda
• Running staff meetings and setting team rhythms
• Creating systems for accountability
• Strengthening cross-functional relationships
• Fostering a high-trust, open team dynamic

From the outside, it might look like the CoS just “runs meetings”, but internally, they’re the glue holding the team together.

This support can be divided into five pillars:

• Interact: Help the team work better together
• Interface: Strengthen connections between this team and others
• Plan: Drive planning and strategic execution
• Measure: Track progress and keep goals front and center
• Communicate: Align messaging across the organization

Orientation 3: Hypergrowth (150+ people)

How to use the framework

Role development

Final notes on leveling

The Chief of Staff role is meant to flex, evolve, and fill the most strategic gaps in an organization. But flexibility doesn’t mean ambiguity has to run the show. Leveling brings clarity around scope, ownership, and impact. It’s not just a snapshot of where your CoS is today—it’s a roadmap for how they can stretch, take on more responsibility, and move up in scope and influence
