Private Equity Meets the Mid-Market: Borrowing PE's Discipline Without the Buyout

01Private Equity Meets the Mid-Market: Borrowing PE's Discipline Without the Buyout

Private equity and venture capital have spent most of their histories as opposites. Venture buys minority stakes in unproven companies and prices the upside. Private equity buys control of proven companies and prices the cash flows. One lives on optionality; the other lives on predictability. For decades that division was clean, and the companies in the middle — too mature for the venture lottery, too growth-hungry or too unwilling to sell control for a traditional buyout — were served by neither tradition especially well.

That is changing, and the change is worth understanding precisely, because it is easy to get wrong. The convergence is not private equity "moving into venture" or venture "acting like private equity." It is the emergence of a genuine middle discipline: minority growth capital that runs on a private-equity operating system. This piece is about what mid-market companies should borrow from private equity, what they should refuse to borrow, and how to tell the two apart.

02Two Traditions, One Convergence

The clean division between the two asset classes rested on a stable cost of capital and a reliable pipeline of companies graduating from venture up toward buyout. When capital normalized and that pipeline thinned in the middle, both traditions started reaching toward each other to find deployable, underwritable companies. Venture-style investors began caring more about economics and less about narrative. Buyout-style investors began looking earlier, at companies that were growing rather than merely stable, and began willing to take minority positions they once would have dismissed.

They met in the middle, and the middle turned out to be the most interesting place to invest — full of companies that are real, growing, and disciplined enough to underwrite, but not yet assets anyone can control-buy or safely lever. Serving those companies well means taking the best of the private-equity tradition and deliberately leaving the rest behind.

03The Old Alpha and the New Alpha

To know what to borrow, you have to be honest about where private equity's returns have historically come from. For a long stretch, a meaningful share of buyout returns came from financial engineering — buying at a reasonable multiple, applying leverage, letting the debt paydown and a modest multiple expansion do much of the work. In a world of falling interest rates, that was a powerful and repeatable formula, and it did not require doing very much to the underlying company.

That era is over. With capital more expensive, the leverage-and-multiple formula produces far less on its own, and the industry's better firms have made a decisive shift: the new alpha is operational value creation — actually making the company better. Improving the go-to-market, tightening the cash conversion cycle, professionalizing the finance function, building the systems that let the business scale without scaling its headcount one-for-one. This is the part of private equity that is genuinely worth borrowing, because it creates value that exists whether or not rates cooperate, and it is exactly the muscle a growth-stage company most lacks.

04What Private Equity Gets Right That Venture Ignores

Sit in enough board meetings across both worlds and the contrast is stark. Venture governance is frequently light — supportive, founder-deferential, focused on the next raise. Private-equity governance is heavier, and in the specific ways a scaling company badly needs.

Three habits are worth importing wholesale. The first is cash discipline — a genuine, unsentimental focus on how much cash the business consumes and produces, treated as a first-order metric rather than something to grow into later. The second is the operating cadence — the private-equity instinct to arrive with a concrete plan for the first stretch of ownership, a small number of high-leverage changes pursued deliberately rather than a vague promise of help. The third is accountability to a number — the expectation that management commits to specific operating outcomes and that the board actually tracks them, which sounds obvious and is startlingly rare in companies that grew up on venture's lighter touch.

None of these require control. They require a partner that has the operating muscle and the seriousness to insist on them.

05What Private Equity Gets Wrong for a Growth Company

Borrowing the discipline does not mean importing the whole model, and this is where the convergence is most often misunderstood. Two features of traditional buyout are actively wrong for a mid-market growth company.

The first is control. A founder-led company that is still growing fast needs the founder's conviction and speed; taking control and installing a buyout playbook can strip out exactly the founder energy that made the company worth backing. The right structure in the middle is a minority position with real governance rights and real help, not a change of ownership.

The second is leverage. The debt that makes a buyout math work depends on stable, predictable cash flows to service it. A growth company's cash flows are, by definition, being reinvested into growth and are less predictable — loading such a company with buyout-scale leverage converts healthy risk into fragility, and turns a bad quarter into an existential one. The middle discipline uses debt surgically if at all, and funds growth with equity that shares the risk it is actually taking.

06The Structure in the Middle

Put the borrowing and the refusing together and you get the shape of operator-led growth equity: a minority investment that brings a private-equity operating system without a private-equity ownership model. Concretely, that means partnering with a company that still has plenty of growth ahead, taking a minority position with meaningful governance rights, and then bringing the operational value-creation muscle — the go-to-market, finance, and systems work — that used to be reserved for control buyouts, applied in service of the founder's plan rather than in place of it.

This is the structure the market backed into because the alternatives failed the companies in the middle. Pure venture would fund such a company but bring little operating help and keep pushing it toward a power-law outcome it may not fit. Pure buyout would bring the operating help but demand control and pile on leverage the growth profile cannot safely carry. The middle keeps the founder in the driver's seat, keeps the balance sheet honest, and imports the one thing venture chronically under-provides: the discipline and hands-on operating help that actually compounds enterprise value.

07DPI, Continuation Vehicles, and the Liquidity Question

The current private-equity conversation is dominated by liquidity, and mid-market companies should understand why, because it shapes the incentives of anyone who invests in them. A long stretch of rising valuations and slow exit markets left the industry holding a great deal of unrealized value and facing investors who increasingly want realized cash — DPI, distributions to paid-in — rather than paper marks. That pressure produced the rise of continuation vehicles and other tools whose entire purpose is to manufacture liquidity when the traditional exit is not available.

For a founder, the lesson is not to master the mechanics of these structures. It is to understand that the best investors are now underwriting for realized return, not just markup — which aligns their incentives with a real, durable outcome for the company rather than a favorable interim valuation. An investor focused on eventual cash return is an investor with a reason to make the business genuinely better and genuinely sellable, which is precisely what a growth company wants standing behind it.

08A Founder's Diligence on the Investor

The convergence means a founder in the middle will be courted by capital wearing many labels, and the label matters less than the substance. A short diligence separates the operating partners from the financial tourists:

1. Where does your return come from? If the honest answer is leverage and multiple timing, you are buying financial engineering. If it is operational improvement, you are buying a partner.
2. Control or minority — and what governance do you actually want? Understand exactly what you are giving up and whether the rights being requested are protective or controlling.
3. What is your operating plan for the first year, specifically? A real growth investor arrives with a concrete, prioritized view. A tourist arrives with a valuation and a wire.
4. Who from your side is in the room after close? The people who won the deal are often not the people who do the work. Meet the second group before you sign.
5. What does a good outcome look like for you, and when? An investor underwriting realized return over a sensible horizon is aligned with you. An investor optimizing an interim mark is not.

Our thesis is ROI² — return on investment and impact — and the middle discipline is where private equity's hard-won operating seriousness meets the growth and mission that drew us to a company in the first place. Borrow PE's discipline. Skip PE's control and PE's leverage. Keep the founder in the seat, the balance sheet honest, and the operating help real. That is not a compromise between venture and private equity. It is the better parts of both, built for the companies the market forgot to serve.
