Chief Of Staff

About the role

We’re hiring a Chief of Staff to work directly with the Founder & CEO, Ari Mir, across Sisu (our founder incubator) and Crative (our operating startup).

This is an early-career, high-ownership role focused on execution and building. You’ll work closely with Ari to move real work forward, with a strong emphasis on helping get Crative’s sales and operations off the ground.

What you’ll do

You’ll act as an extension of the founder, stepping in wherever work needs to get done.

At Crative, you’ll focus on sales and go-to-market execution, including:

• Running outbound (prospecting, outreach, follow-ups)

• Managing CRM and tracking pipeline

• Converting inbound interest into customers

• Improving onboarding and early customer experience

• Building simple systems and workflows to make sales more efficient

• Using tools (AI, automation, no-code) to increase leverage

At Sisu, you’ll:

• Support founder programs and day-to-day operations

• Help improve internal processes and launch new initiatives

Across both, you’ll:

• Own projects end-to-end

• Turn ambiguity into clear next steps

• Help Ari switch between priorities by taking ownership of execution

What we’re looking for

You’re highly capable, practical, and execution-oriented.

You:

• Take ownership and move quickly

• Are comfortable working on early-stage problems

• Communicate clearly and represent the founder well

• Know when to act independently vs align

• Are organized and follow through

• Are resourceful and build solutions, not just ideas

Strong academic or early professional track record (top schools, competitive internships, or high-growth companies) preferred. Best suited for candidates with 0–2 years of experience who want to learn by doing.

This role is an excellent stepping stone for anyone interested in operations, startups, or future entrepreneurship.
