Don't have time to conduct full blown user-research to understand your users? When I joined the company, I was in a similar situation, so conducted to get a hint about how the current users of SwitchMe are, who converts, who doesnt converts etc. I invited total 8 people from the customer-facing sales team, support team and founders of the company to this workshop. After that I spoke with a bunch of customers from each segment to validate/discard my learning from the data collected from workshop.
