From a platform perspective, how do you identify ICPs? Are you focused on a cluster or individual ICP?

Assuming ICP stands for Ideal Customer Profile, you need to have a clear understanding of the persona you are targeting with your platform. For that persona, you could target different profiles of companies - enterprise, SMB or small shops, depending on your business goals.

Whether I focus on a cluster of ICPs or individual ICPs usually depends on (I) time constraints and (II) 0-1 vs 1-N product motion. Usually, when I pitch a new idea to my executive team, I like to clearly articulate a big picture using data and trends and then deep dive into individual customer anecdotes. In other words, I combine explore and exploit strategies and limit my research with just enough data to kick off the debate. This allows me to quickly iterate on everyone's feedback and make a better decision if the cluster or individual ICP aperture is a better fit in my case.
