We contacted leaders in our industry that we knew personally from networking, and asked them to beta it. We had a new product that hadn't been seen before in our industry, directed specifically and precisely for their needs, and we proved that they would save money immediately. So, we piqued their interest and got them to invest their time in the beta. Other people we contacted were active people in the active industry forums. This helped get the word out by way of trust.
