The timing couldn’t be better for me. With a whole new team of resellers I need to take inventory of my biases and how I’m coming across to them. I plan to practice humility intentionally and find a coach or two for 2019. While the funnel process content is valuable, the Blindspots observations and examples were priceless. What sales leader shouldn’t read this book? No one I can think of. Well done!

As sales managers, our job is to help sales people understand their 'blindspots.' We want to help them recognize these barriers to their ability to maximize their performance. Ironically, it is often our own blindspots as managers that adversely impact what we seek to achieve with our people. In his book, Blindspots, Mark vividly illustrates this problem in our own behaviors, and clearly identifies how we can eliminate them, connecting effectively and impactfully with our people. Blindspotsis an outstanding guide to help managers get out of their own way and develop their people.

Mark has inspired me as a leader by writing about and demonstrating the strength of vulnerability in his recent book, Blindspots. This book is a classic ‘what to do and what not to do’ as it demonstrates the impact that can be had when leaders focus on influencing behavior as a means of influencing results.

I've trusted Mark in front of my clients as a coach/trainer and am particularly impressed with his care and interest in sales leadership. He has a knack for getting sales leaders to buy into new processes. He's collaborative instead of prescriptive. In Blindspots, Mark shows where he gets this compassion from and explains how any sales leader who's determined to get better can do so.

This book will surprise with you many gems: its counterintuitive perspective on the challenges of data and transparency, the types of sales managers and blindspots and how to get out of your own way, the power of emotional connection to fuel relationships and coaching effectiveness, and more. Most importantly, for me, is the power of the BuyCycle Funnel™ for helping salespeople sell better by focusing on where the customer is in the decision making cycle. Frankly, Mark has been flipping the funnel for years, and it’s time for the sales profession to pay closer attention. I’d recommend this book for this reason alone, but as I’ve mentioned, there’s plenty more, weaved into a myriad of relatable stories and analogies that make it a quick and easy read, for something with so much value.

Every year we layer on complexity to the role of the sales manager without taking anything off. As a sales leader myself, I can attest that the process of prioritizing our efforts to help our teams drive results is mystical at best. Rather than focus on theory, Blindspots provides practical guidance around the power of data available in all organizations, how to organize that data into meaningful patterns, and most importantly, how we can get out of our own way and create a path towards success when coaching our sellers.

Mark’s latest work, Blindspots, is a great reminder of the complex human relationships we encounter in coaching a sales team. Mark does a great job illustrating the areas where we as leaders tend to get stuck. His input and guidance into my business is very valuable and it’s no surprise that his book is equal to that standard. Blindspots will be worth your time to read.

We have been working with Mark for a little over two years, and I continue to be impressed with his level of knowledge and his desire to keep learning and evolving. Blindspots is a great example of this. As someone who has spent most of my career outside of sales, my time with Mark has helped me understand better what it takes to win in sales.

In Blindspots, Mark walks the walk about making an emotional connection with people. He’s honest, transparent and vulnerable—things he encourages sales managers to be in order to create their own emotional connections with their salespeople. These emotional connections create motivated salespeople, and motivated salespeople will hit quota.
