The holding company

We are the buyer
with no exit date.

Harrow owns controlling stakes in durable businesses and does not sell them. There is no fund behind this page, no vintage year, and no partner waiting for a liquidity event.

A company does not become worse
at what it does because
it turned eleven.

Nearly every buyer a founder meets is on a clock. A fund raised in 2021 has to return capital by 2029, so the business it buys in 2026 will be sold in 2031 whether or not that is the right year for it. The clock is not malice. It is the structure.

Harrow is capitalised by four families and its own retained earnings. There is no fund, no vintage, and no obligation to produce a liquidity event for anyone. We buy a controlling stake in a business we believe will still be needed in thirty years, and then we hold it. Seven businesses, sixteen years, none sold.

That is not patience as a virtue. It is arithmetic. A business we hold for twenty years compounds through four cycles instead of one, and never pays the six per cent of enterprise value that a sale process costs. We would rather own the cash flow than harvest the multiple.

“The only question we ask that other buyers do not: what does this business need in year twelve?”

IV  For independent sponsors2 of 7 came this way

Bring us the deal you cannot fund on a five-year story.

Seven businesses sit on our register, and two of them came to us from independent sponsors who had the relationship and the diligence but not a buyer who could hold the asset the way the seller wanted it held. We wrote the equity, the sponsor kept a real promote, and in both cases the sponsor still sits on the board.

What we offer a sponsor is the thing a fund cannot: a credible answer when the founder asks what happens in year six. We will say, in front of your seller, that we intend to own it permanently — and point at a register where that has been true seven times out of seven.

“You keep the relationship. We take the thirty-year risk.”

Terms, in public, because they do not change.

For owners

Ask what happens in year twelve.

Send three years of statements and a description of what the business actually does. A principal answers, not an analyst, and you will get a view on price and on whether we think the business should be sold at all. We have told four owners not to sell; two of them are still running their companies.

Write to a principalowners@harrowpartners.example
For sponsors & capital

Terms are in Section V. Nothing under them moves.

Independent sponsors with a signed letter and real diligence: we can confirm equity in ten business days and will stand in front of your seller. Families considering capital: the last three annual holding letters and the appraisal methodology are available on request.
