The Strategic Partner for High-Growth Startups
You're the visionary — I help you turn strategy into execution, build operating cadence, and remove roadblocks without adding headcount.
Trusted by teams at
You are the Visionary. But you're stuck in the Weeds.
The Problem
Scaling widens the gap between strategy and execution. What worked at 10 people breaks at 50.
The Symptom
You spend ~70% of your time on operations and only ~30% on high-value growth activities.
The Risk
Burnout, slowed momentum, and team misalignment become inevitable without intervention.
You don't need more hours in the day.
You need a force multiplier.

Experience From
Professional Background
I bring the rigor of management consulting with the scrappiness of a hands-on operator. From advising clients at EY to managing $200k+ monthly marketing budgets at Getir, I've seen both sides — the boardroom strategy and the ground-level execution.
This dual perspective is what allows me to bridge your vision with tangible results, fast.
