You can bring in business and feel great about how you do it.


Anyone can improve their business development skills.
Like with any skill, business development can be learned. Our process consists of 17 different modules covering every aspect of business development: lead generation, creating demand, building relationships, talking about money, closing more business and every other skill you need to be successful.
Science and steps, not motivational rah-rah.
We focus on the seller-expert, a professional with a deep expertise that also has to grow client relationships. We teach seller-experts how to grow their book of business efficiently and effectively.
We’ve taught over tens of thousands of professionals at over 400 organizations. Anyone can learn our system. Anyone can improve. And because everything we teach is focused on the client and their needs, it feels great to use.
The system is rooted in behavioral science, with over 130 university-driven peer-reviewed scientific studies at the core.
Science + steps = success.

One of the key techniques is the assessment of thinking styles…I use that technique more than anything else as I'm having client interactions. It allows me to frame discussions…so that they have more impact. It's been a very valuable technique I use daily.
