On the measurement of slow phenomena.

ABSTRACT

We examine, across a panel of 312 European venture funds and eight vintages, the relationship between investor cycle time and net realised return. We find that faster decision cycles are negatively associated with realised IRR in funds vintage 2018 and later, with a structural break visible in Q4 2022. Methods and limitations are discussed in §III.

§ I.1 · INTRODUCTION

Patience, considered as an operating practice.

An almanac of slow capital begins, as all such accounts must, with a definition of its own terms.1 By patience we mean not the absence of action but its considered deferral — a discipline of writing things down before speaking them.2

The Eurozone venture record offers a useful natural experiment. Cycle times across our panel have, on average, tripled since 2018; realised returns have risen materially over the same window.3 We do not propose a single mechanism; we propose that the data have stopped agreeing with the older operating story.

A SHORT NOTE

The fastest single-quarter outflow on record.

Most of it flowed not to safer instruments but to private credit and direct lending — a structural rotation, not a panic.

The fastest investor on the table is no longer the one who reads the room. They are the one who has stopped reading altogether.

§ II.1 · TWO OPERATING MODELS

Two operating models, ten years apart.

2016 · MODEL A

Speed as moat.

Closing fast was the strategy. The fund that returned a term sheet by Friday usually won the round, regardless of price.

2026 · MODEL B

Patience as moat.

Diligence cycles have stretched from four to fourteen weeks. Realised returns up 8.2pp over the same window.
