Who founded Lexi AI?

Built By Founders Who Have Done It.
Lexi was built by David Goldstein and Matthew Henderson — serial entrepreneurs who built the businesses, wrote the system down in the Amazon bestseller The 9% Club, and then built everything they know into her.
David Goldstein
David has spent nearly two decades building award-winning ventures, including a "Top 5 Technology" recognition at Techweek NYC. As a Forbes Business Council member, he has guided hundreds of entrepreneurs from chaos to systematic success.
Along the way, he watched the same story repeat: brilliant founders drowning in the day-to-day, not because they lacked talent, but because they lacked systems. Every fix he found, he documented. Every framework he tested, he refined.
Matthew Henderson
Matthew is a serial entrepreneur who has scaled multiple ventures into market leaders. His talent for building high-converting sales funnels has generated millions in revenue across industries.
But the pattern that fascinated him most wasn't what made funnels convert — it was what made businesses survive. The answer was never hustle. It was an operating system. That realization led him to co-found Lexi AI — and to build the operating system right into her.
Two Founders. One System.
Together, David Goldstein and Matthew Henderson generated over $1 million in their first 4 months. They are the co-creators of the S.T.E.A.R. Operating System, the co-authors of the Amazon bestselling book The 9% Club, and the builders of Lexi — an AI business partner trained on everything they know.
Why They Built Lexi
Lexi didn't start as an AI project. She started as four decades of hard-won lessons looking for a way to scale.
They built the businesses.
Forty-plus combined years. Eight-plus companies. Wins, expensive failures, and everything in between. David and Matthew didn't study how businesses succeed — they lived it, payroll by payroll.
They wrote the system down.
They distilled everything that worked into the S.T.E.A.R. Operating System — Strategy, Tracking, Execution, Accountability, Results — and published it as The 9% Club, an Amazon bestseller with proceeds donated to AMVETS.
Then they brought it to life.
They took the system, the book, and everything they know about running businesses — and built it into Lexi. An AI business partner who doesn't just teach the playbook. She runs the plays. 24/7, inside your business.
Lexi: "David and Matthew built me on everything they learned the hard way — so you don't have to learn it that way too."
Learn the System.
