Fractional COO & Interim Executive

Stop being the bottleneck. Build what runs without you.

Workstream Studio designs the operational architecture that lets founders and leadership teams step out of every decision, without losing control of the ones that matter.

Approach

The layer most ops consultants skip

Most operational problems have a people dimension underneath them. We read that layer first, who can actually step up, where the real friction lives, what the team will accept or resist, then build systems around how people actually work.

Founders often describe the result as having a clone: someone who thinks like an owner, not a consultant. Systems only stick when they fit the organisation they are built for.

Decision-making architecture

Decision rights, meeting cadences, and accountability structures that make ownership clear, so the right calls happen at the right level.

Operational systems

Workflows, KPI dashboards, and documentation that actually get used, built into how the team operates rather than filed away.

Team & leadership capacity

Identifying who can grow into what, and building the conditions for it to happen, so capability scales with the business.

How we work

Three ways to bring an owner's thinking in

Engagements are scoped to the moment you are in, from ongoing partnership to a focused transformation to stepping into the seat itself.

Interim CEO through a leadership transition

Stepped into the interim CEO seat for an education NGO navigating a critical leadership transition. Held operations and the team steady, set the organisation's forward strategy, and drove the fundraising agenda to secure its next phase, while preparing a clean handover to the incoming leader.

In their words

What it is like to work together

It felt less like hiring a consultant and more like cloning myself. Within weeks the team was making the calls I used to get pulled into, and making them well. The business finally runs when I step away.

Most advisors hand you a deck. Yenson read the room first, who could step up, where the tension really sat, then built structures the team actually accepted. As a board, we finally trusted the organisation to hold.

We were mid-transition with no playbook. Yenson stepped in, steadied operations, and left us with documentation and decision rights that outlasted the engagement. Calm, rigorous, and genuinely trustworthy.

About

Built on 18 years of operating, not just advising

Workstream Studio is led by Yenson She, a fractional COO and interim executive. Over 18 years across global consultancies and high-growth companies, the work has spanned strategy, operations, and the leadership transitions in between.

The studio works with founders and leadership teams of 10 to 100 person companies who have built something real and are ready to build the infrastructure to scale it, across both commercial and mission-driven sectors. What makes the work different is an organisational-psychology lens applied to every engagement: read the people first, then build the systems around how the team actually operates.
