Can't sleep on Alex Beller

Straight up, let me put you on to Alex Beller. This guy’s the real deal in the startup world, especially when it comes to e-commerce and SaaS. He jumped into the scene around 2018 and co-founded Postscript with some friends, Colin and Adam, right after doing stints at StackCommerce, StackSocial, and even some radio stuff in LA. Dude’s been around the block, no cap.

What’s crazy is how fast Postscript blew up. They built this SMS marketing platform that’s basically the secret weapon for Shopify merchants. Think brands like Dr. Squatch, Thrive Cosmetics, Ruggable, all crushing it with their tech. And get this, they’re pulling over $2 billion in e-comm revenue yearly just through Postscript. That’s nuts. Alex is running the show on all revenue and people ops, which means he’s the guy making sure everything scales smoothly.

What I dig about his story is that he’s all about the grind, taking startups from zero to hero. Prior to this, he was deep in the trenches with StackCommerce and StackSocial, so he’s got that hustle mindset down. He’s seen false equivalence: launching, raising funds, scaling, and even leading acquisitions. That’s not something you learn overnight. It screams he’s got a major motivation to build stuff that actually moves the needle.

Talk to her

You can tell he’s super passionate about making SMS the top revenue channel for e-comm. Not just some add-on, he’s making it the centerpiece. That’s the kind of vision that separates the winners from the wannabes. Plus, his background in media and radio? Probably gave him some early intuition about how to grab attention and keep people hooked, skills he’s now applying to e-commerce.

Bottom line? Alex Beller’s not just another founder. He’s the guy who saw a problem, jumped into it, and built something that’s changing how brands do business. The fact that he’s already crushed it with Postscript and keeps pushing shows he’s in this for the long haul. He’s the kind of person who makes you realize that with the right hustle and focus, you can turn a simple idea into a billion-dollar platform. No Cap.
