Investor Co-investors

Introduction

Returns the other investors that a given investor has co-invested with - that is, the firms that have appeared in the same deals. Each row is a minimal investor reference plus a count of shared deals and the first and last dates on which both investors participated together. Use it to map an investor's syndicate, surface frequent collaborators, or rank co-investment relationships by recency and volume.
