Use Capital IQ to do a search on PE/VC firms and add criteria that includes key executives and board members under the section "Employee Details" with, for example, a consulting background (ie: worked at McKinsey, or other firms).

We have found that if you then look at this list, perhaps limited by geography, you can find firms that may have a concentration of people for whom consulting was their background.

If there is more than one person with that background, it tends to denote firms that may value that experience perhaps a bit more.

You can add an additional layer to enhance your networking by including a search for HBS Alumni or alumni of other institutions you have attended.
