Michael Abbott spells his philosophy out clearly and specifically:

in series a, i like to lead. by nature, i want to find investments and founders where i can effectively lead a deal, participate on the board in some way, and really put my muscle into recruiting, technology development, and other key considerations. this means that you’ve already been working on something for a while, perhaps taken seed funding to begin with, and now are looking for a real investment partner. i’m lucky to be at kp, with a wealth of resources the firm as to offer, as well. basically, i want to find situations where my presence and kp’s presence could lead to outsized success and possible breakthroughs.

It's very hard to find leaders in venture capital.

Kudos to Mike for expressly stating what he's looking for.
