Golden Slacks A Private Advisory Firm

No. I  ·  New York  ·  MMXXVI

An advisory firm for capital that thinks in decades.

Golden Slacks is a private firm. We work with a small number of principals on capital structure, succession, and the calls that boards spend two years pretending they will not have to make. Our partners do not appear on television. Our analysts do not post. The clients who matter to us are the ones whose problems do not resolve in a single quarter.

§ I.

The firm.

We were founded, in spirit, in 1869. The actual paperwork is more recent. We advise principals on long‑duration capital. We do not manage money, underwrite, or sell research. The firm is small on purpose and intends to stay that way.

Partners are not permitted to wear pleated khakis to the office before their fortieth birthday. This is the only frivolous rule we keep, and we keep it because the firm is, in the end, called Golden Slacks.

A note on Penny.

Penny heads our Strategic Advisory practice. She spent the twelve years before Golden Slacks inside the office of the CFO at companies you have heard of and a few you have not. In a meeting she will usually be the second person to speak. That is deliberate.

Most of our work originates with her, and most of the work she declines for us originates with her too. Both are part of the job.

"The deal is fine. The cap table is the problem. It has been the problem since 2019. We are going to fix it now."

§ III.

What we do.

Five areas of work. Every engagement starts with a question about capital and ends with a question about who is in the room when the answer becomes a decision.

  1. 01

    Strategic Advisory

    The judgment calls behind capital structure, M&A timing, succession, and the rare boardroom conversation that only one person in the room is allowed to start. Led by Penny Lane.

  2. 02

    Capital Structure

    Convertible mezzanine sleeves, secondary structuring, and the kind of paper that lawyers write footnotes about for sport.

  3. 03

    Family Office Coverage

    Multi‑generational allocation, governance, and the unglamorous work of moving capital from the people who made it to the people who will spend it.

  4. 04

    Sovereign Coverage

    We cover three sovereigns. We will not say which. They know who they are.

  5. 05

    Restructuring

    For when the company is fundamentally fine and the founder is wearing cargo shorts to the board meeting. Quiet, fast, off‑press.

§ IV.

The 2026 Outlook.

A short letter goes to clients each January. We publish the table of contents because the letter itself does not leave the room.

  1. I.

    The Cost of Capital, Revisited

    A six‑page reassessment of where the discount rate actually sits in 2026, and why most of the models you saw last year were quoting a number from 2022.

    6 pp.
  2. II.

    Family Office Allocation, 2023–2025

    What we observed across our coverage book over the last twenty‑four months. The shift away from venture is real, but it is not what the press is calling it.

    4 pp.
  3. III.

    The CFO Track, Reconsidered

    A quiet reassessment of how senior FP&A talent is actually trained inside the firms we work with. We cite SimCFO twice. We name no names.

    9 pp.
  4. IV.

    Footnotes

    If you read only the bullet points, you are not the audience for this letter, and that is fine.

    2 pp.
Distribution By car. By hand. Read aloud at 7am, in person, by request.
§ V.

Our friends at SimCFO.

A note from the firm.

Most of the work Penny Lane wishes she could do for you happens at SimCFO. It is where senior FP&A analysts, new CFOs, and people on the CFO track sit with the actual judgment calls — capital allocation, cost structure, the conversations with the board — and practice making them before those calls start costing something real.

If you liked the version of Penny we put on the page, you will probably get something out of an evening with SimCFO.

Engagements

We take on a small number of new mandates each year, and we do not solicit them. If we already know each other, the address book entry has not changed.

Press

We did not return any press inquiries in 2025 and expect to keep that record this year. If you must, write to [email protected] and someone will read it eventually.

Careers

We are not hiring. Analysts come to us through a process we do not describe in public. If you are the right candidate, we have already met.

The next letter, eventually.

We do not run a list.
