I was always looking for a business development system that made sense in our high-end, expert-driven world. We found one in Mo’s method. The Snowball System is accessible and easy to implement, but most importantly, it works. I cannot recommend it highly enough.

Anyone can improve their business development skills.

Our founder and CEO, Mo Bunnell, started out as an actuary – which is about as far as you can get from being a wine-and-dining salesperson. We don’t believe being great at business development has anything to do with being “born with it.”

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.

Mo's process allows you to be intentional, which, bottom line, almost assures you of positive results.

– Russ Richards, Senior Partner, King & Spalding

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 15,000 busy 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.

If you follow the training modules we've had over the last couple of days, you'll be in a very good position to take on even the most difficult of clients.
