In-house operating partner, outsourced, or consulting firm: which one?
The three do not answer the same question. The in-house operating partner makes sense when the portfolio is large enough to keep someone busy full time and the fund wants a permanent presence on boards. The consulting firm makes sense when you need temporary firepower on a defined question — a diagnosis, a market study, a heavy workstream. The outsourced operating partner sits between the two: a lasting presence across several portfolio companies, a few days a month, without a fixed cost, who does not stop at the recommendation but deploys the plan with the teams.
When does an in-house operating partner make sense?
When the portfolio reaches a size that keeps someone busy full time — in practice, around ten active companies — and when the fund wants a person present on boards, known to the CEOs, with a share of the carry.
Its limits are those of any single profile. A former industrial director will not be the right person on a commercial or digital subject; you then have to hire again, or go outside. And the cost is fixed: it runs whether the portfolio needs them or not.
What does a consulting firm bring, and where does it stop?
A team, a method, capacity. On a commercial due diligence, a market study, a cost programme, it is the right tool: you need hands, a proven method and a short deadline.
What it does not do, by design, is execution. The mandate ends when the recommendation is delivered; the portfolio company's teams must then apply it, with their own means and their own agenda. That is where most of a plan's value is lost: between the hand-over of the document and the first quarter.
When is the outsourced operating partner the right choice?
When the fund is not large enough to bring the role in-house — the case for most small and mid-cap funds — but needs a continuous operating presence across two to four portfolio companies.
When the subject calls for someone who has run a business, not only analysed one: a value creation plan is built with a CEO, and a CEO listens to a peer.
And when what remains matters as much as what is delivered: an outsourced operating partner works over time, so they see their plan executed, correct it, and leave tooled processes behind rather than a document.
Can they be combined?
That is the most common set-up, and the most effective. An in-house operating partner steers the portfolio and arbitrates; they bring in an outsourced one to absorb two or three companies they cannot cover, or for a skill they do not have — AI, ESG, turnaround. And both call on a firm when a bounded subject needs firepower.
The question is therefore not "which one", but "who does what": who decides, who executes, who stays once the work is done.
Three questions to decide
How many portfolio companies need real operating attention at the same time? Below five, a full-time role is hard to justify.
Do you need an answer or an execution? An answer is bought as an engagement; an execution needs someone who comes back every month.
Who, inside the company, will carry the plan once the provider has gone? If the answer does not exist, none of the three models will work — that is where to start.
