Yes, we have several filters built into the platform (including specialty, age, practice setting, years in practice, location, to name a few) that allow you to segment or “micro-profile” your Crowd before you begin. Additionally, you have the ability to ask large groups of respondents custom screening questions and then ask the intended question only to those who responded in a particular way (for example, oncologists who have prescribed Taxol in the last 3 weeks).
