What is the speaker mainly discussing?

It’s amazing how quickly our group has grown. We began with 15 people a little over 4 years ago. We used to meet out at the airport to talk about retail marketing; we were focused on sharing marketing strategies and trying to find new retail opportunities for a variety of banking products. Over time, we put together a line of marketing approaches for financial services that several companies have seized upon. We now routinely speak at financial services conferences and provide private consulting. Our group of 15 people has grown to more than 200, and we take up a lot more office space.
