Praise from Keystone Participants

“I had seen Billy's marketing handiwork in the wild, and that led me to sign up for his Keystone accelerator. I was looking for an additional edge in selling our cohort-based courses and thought Billy's training could help.
We've sold over $75M in online courses over the years, so needless to say, we have high standards when it comes to marketing training.
Billy is the real deal. His approach to marketing is simple, authentic, and powerful.
We're now using his messaging framework to improve our campaigns. If you have the chance to learn from him, take him up on it.”
Ryan Deiss,
Founder & CEO, DigitalMarketer.com and Scalable.co

“I’ve never, in all the years I’ve sold things online, had the quantity or passion of replies I’m getting.
Thanks this accelerator and The Five Lightbulbs approach, I launched a premium product. I launched in June, and it's now September that I record this.
I've never earned so much from one product. And my customers are happy. They love it.
I'm extremely grateful to Billy, The Five Lightbulbs, and this accelerator - including all of my colleagues in the cohort who really helped me get to here.
I strongly recommend, if you've been selling online for a little while, and you want to juice up your sales, join Billy, learn from him, and enjoy the benefits."
Reuven Lerner,
Python consultant and online educator

“The accelerator was a game-changer for me.
Before the course I felt like I was shooting in the dark trying to come up will compelling sales messages and emails for my online course. It took me forever to write a simple email. And then when I finally wrote something I had no way of knowing if it was even the right message for the right audience.
This accelerator completely changed that.
With the 5 Lightbulb Framework, I felt like the fog lifted on how to write good marketing and sales copy. I can now write compelling emails for my launch quickly, on message, and to my target audience. Billy’s approach to writing sales copy is creative and authentic.
He is an inspiring and generous teacher who can break abstract marketing concepts down into manageable pieces.
Instead of dreading my next launch, I am excited.”
Gwyn Wansbrough,
Faciliation expert and trainer

“I doubled the price on my course, so I thought, ‘Okay, well it's probably gonna take longer to sell out these 50 spots.’ I sent out the opening cart email on a Monday, and by Tuesday at the same time, it's completely sold out.
Anyone who wants to sell their stuff in a mega authentic way, in an almost Zen master sort of way of selling – I'd highly, highly recommend Billy's accelerator.”
Akash Thakkar,
Composer and Video Game Sound Designer

“I have done all the big names from Ryan Levesque to Frank Kern, to everybody else you can imagine.
This simple framework that Billy teaches is a game changer.
In my world, as a business owner, there's before Keystone and after.
Christy Brennand,
Founder of More Heart Less Body weight loss program

“So I've done courses, I've done workshops, one-day events. I've listened to TED Talks. I've read books. And I have learned a lot about marketing. Some of these events were run by the gurus of the marketing industry. So my knowledge is vast when it comes to marketing, but they all failed to deliver on the how.
Billy's 5 Lightbulbs accelerator is the most practical course that I have ever done. It is by far the most non-BS marketing course. We literally walked out with a physical marketing playbook that we could deploy to our databases.”
