The hard partis the second decade.

We write $25M–$200M into technology-enabled businesses that have already proved the thing works and now have to make it big. Fourteen of the last twenty were the first institutional money on the cap table.

01Thesis

Growth is when a good companygets the chance to break itself.

A business that has found its market is not safe. It is exposed. The thing that made it work — a founder who knew every customer, a product that fit one segment exactly, a sales motion that lived in one person's head — is the same thing that cannot survive being multiplied by ten.

We invest at that point, and only at that point. Not at the idea, where we would be guessing, and not at the roll-up, where the answer is arithmetic. In between, where the answer is operational and the failure modes are boring: the second product ships late, the first VP of Sales does not work out, the pricing model was never a model, the data room reveals that nobody has closed the books in nine weeks.

Our diligence is unromantic on purpose. We read the churn cohort by cohort. We call twelve customers, not the three the company chooses. We build the operating plan before we build the model, because the model is downstream of whether the plan is possible. Then we say a number and we do not re-trade it.

“We are not looking for a company that needs us. We are looking for one that would be fine without us and would be two years faster with us.”

02Where we invest

Four bands.The same filter applied to each.

01

Vertical software

Systems of record for industries that still run on a spreadsheet and a phone call. We care whether the software is where the work happens, not whether it is where the reporting happens.

41companies
since 2003
02

Payments & embedded finance

Flow businesses with a real take rate and a regulator who knows their name. We underwrite the licence stack before the growth rate.

27companies
since 2009
03

Technology-enabled services

Margin structures that improve with volume because software absorbed a step a human used to do. If the gross margin is flat at scale, it is a services business and we are the wrong buyer.

38companies
since 2006
04

Infrastructure software

Sold to engineers, renewed by finance. Long sales cycles, long lives. The only band where we will accept a negative first year.

03After the wire

What actually changes,and what deliberately does not.

What changes

The finance function, inside ninety days

A close that lands in five business days, a cohort model that survives an auditor, and a forecast the board can argue with. It is unglamorous and it is the thing that most often was not there. We have never once found it already working at the standard we need.

Hiring, at a rate nobody expects

Eighty-one executives hired into portfolio companies in twenty-three years, against two chief executives removed — both times at the founder’s request. The ratio is the point. Our talent partner sits with the company two days a month for the first year.

Price

Every company we have owned has raised price at least once, and every one of them expected it to go worse than it did. We bring the analysis and the scar tissue; the decision stays with the company, and twice it has been no.

What does not

Week one

No hundred-day plan written by someone who has met four of your people. The first fortnight is reading and listening.

The name and the building

Unchanged in every one of the twelve current positions.

The leadership team

Unless it is broken. We bought a minority of something that already works.

The board

One seat, eight meetings a year, papers on the Thursday. The company is not run from it and we do not pretend otherwise.
