Kerem Çebi - Fractional Chief of Staff, strategic advisor for startups

You're Visionary. But Drowning in Operations.

Problem

Scaling widens the strategy-execution gap. Methods that work with 10 people break at 50.

Symptom

You're spending ~70% of your time on operations, only 30% on high-leverage growth activities.

Risk

Without intervention, burnout, loss of momentum, and team misalignment become inevitable.

You don't need more hours.
You need a force multiplier.

What is Fractional Chief of Staff?

The strategic layer between your vision and company execution.

Not an Assistant

I manage priorities, not calendars.

Not a Full-Time COO

Strategic thinking without the full-time cost or equity dilution.

What Am I?

Your deputy, strategic advisor, and execution force rolled into one.

Frequently Asked Questions

Everything you need to know before getting started.

I typically work with Seed through Series B stage startups (5-100 employees) that are experiencing scaling pains between strategy and execution. That said, I've supported more advanced companies on specific projects.
It depends on the model. Audit is an intensive 2-week project. Ongoing support models typically involve 10-20 hours per week or 2-3 full days embedded. Project-based work is scoped individually.
An EA manages your calendar; I manage your priorities. A PM runs projects; I design the operating system. A COO is a full-time executive; I deliver strategic impact without equity dilution or high overhead.
We set clear KPIs upfront — usually around meeting effectiveness, decision velocity, and leadership alignment. At 30 days, I deliver an impact report with measurable results.
Yes, when it's valuable. I typically help prepare board materials, facilitate investor updates, and can participate in meetings as a strategic resource.
A 20-minute discovery call to understand your challenges, access to your team and tools (Slack, Notion, etc.), and commitment to a kickoff session. Engagements typically start within 7 days.
