Meet The Man Behind The Growth Stack…

I’m Andrew Cass, founder of The Growth Stack and best-selling author of Sales Velocity…
For over 20 years, I've worked directly with service-based business owners like you to help them grow their leads, increase sales, and stay ahead of major technology shifts — because let's face it, technology can be like kryptonite for many business owners.
I've helped multiple clients land on the prestigious Inc. 5000 list — including my own software company in 2024. And for nearly two decades, I've been leading monthly, in-person mastermind groups in South Florida — focused on business growth, strategy, and execution. You'd be hard-pressed to find anyone who's led live, in-person groups like these longer or more consistently. (Hey, if you're in South Florida, shoot me a message — I'd love to tell you more about our monthly groups!)
I started old school — direct sales, marketing, systems, and relentless execution. But I’ve evolved with the times. Today, I help service-based business owners blend timeless business principles with modern, AI-powered systems to thrive in the new AI economy.
Now, I’m bringing those same high-leverage strategies straight to your inbox each week.

P.S. How We Can Help You Grow & Scale — Starting Now!
Here's the truth — most service-based business owners are still overpaying for a patchwork of disconnected tools that kill their time and their margins. Meanwhile, the smart ones have moved on…
The fastest-growing service-based businesses today are building and scaling on ONE core AI-powered business operating system that makes every other platform obsolete. The one-and-only system we use and recommend is HighLevel — and it's the same foundation behind all the AI strategies, tools, and ideas you'll read about in this newsletter every week. CRM, AI-powered automation, funnels, email, SMS, and more, all under one roof. Plus, a full AI Employee Suite that answers your calls, responds to leads, books appointments, manages your reviews, and nurtures prospects 24/7 — without adding headcount. Those who consolidate their AI tech stack into HighLevel are saving $1,000 or more per month on average — all inside ONE powerful cockpit.
