Where AI Automation Breaks Down
September 30, 2026
Before AI can run your business, your business needs something for AI to run on. Isaac Harmon, founder of Harmon Digital and Unstack, joins Aaron Marchbanks and Justin Edwards to talk about where automation hits its limits. They cover the signals that a company has outgrown its systems, why tools like CRMs have lost their moat, and when businesses should import and customize existing software rather than build from scratch. They also dig into how the bottleneck is shifting from the people doing the work to the people checking it, and what that means for anyone relying on orchestration agents.
This podcast is brought to you by Delta Systems, your one-stop shop for front-end, back-end, and full-stack software development. At Delta, Justin and Aaron share the same philosophy when it comes to clients: they treat people like colleagues, not just customers. Maybe that’s why Delta typically spends years working with the same companies: how many software engineering firms can you say that about? So, if you’ve got a big SaaS project in mind but have no idea where to start, come and get a free scope and estimate from Delta Systems at: https://deltasystems.com/
