Fractional C-Level

Part-time C-Level · resident advisory

The agreed hours are spent inside the company. It is a seat that takes responsibility for execution, not advice.

“We have not hired anyone for that seat yet, but the work has to move now.”

Growth-stage companies with a C-level gap

There is a stage where it is too early to appoint a C-Level and too late for the founder to do everything. Usually between 20 and 30 people. At this stage, if you hand out the title without the authority, that person leaves within six months.

A part-time C-Level means spending a set number of hours inside the company. Joining meetings, writing documents, sitting in on hiring interviews. Different from an advisor who only gives advice from the outside.

Fit

When it fits, and when it does not

This is when to reach out

  • When you have to build the organization right after fundraising, but no one is there to do it
  • When a 6–12 month gap is expected before a full-time C-Level hire
  • When you're standing up a new business unit and need someone to carry the first six months

In these cases I recommend a different approach

  • 이름만 올리는 자문역이 필요한 경우, 그 형태로는 맡지 않습니다
  • 상근 임원이 필요한 경우, 그건 채용으로 푸는 게 맞습니다

C-06 Investment · M&A M&A · Valuation 2025 · In-house business · Directly executed

Sell-side IR written directly for a KOSDAQ-listed company

We reviewed a sale as the next step for a business we held. Using an advisory firm meant certain costs and uncertain results.

What I did
  • We first analyzed the strengths and weaknesses of the acquisition target, then mapped where our business fills those weaknesses
  • I wrote the IR myself using comparable company valuation based on the market caps of listed peers
  • Pitched the executive team directly and handled roughly six months of due diligence
Results
  • Advanced to executive review at a KOSDAQ-listed company · due diligence completed
  • Separately, I ran 3 M&A deals end to end myself: target sourcing → due diligence → valuation and terms → contract → PMI
  • This experience became the basis for “what acquirers and investors actually look at” in IR coaching
What we learned here

Valuation is not a negotiating chip — it is the argument the other side has to take to their board. The job is not proving what your company is worth; it is giving them the reason they can justify that number.

FAQ

Frequently Asked Questions

Ask more →
How many days a week are you on site?
We set the hours on a monthly basis. Meetings and document reviews are the baseline, and it grows when hiring is involved. We settle this in the intro call.
Do you avoid taking on competitors at the same time?
I don't take on work that overlaps in the same market. We check that first in the intro call.
What about the contract type?
We start with a monthly advisory contract and adjust once the scope is fixed. Terms are proposed after discussing scope.
