What are the can't-miss AI tools for SaaS founders?

In this episode, Rob Walling sits down with Craig Hewitt, founder of Castos, to dive deep into Craig’s “100 Days of AI” YouTube series. They discuss the lessons learned from exploring the latest AI tools for founders, why ChatGPT might not be the best option for SaaS entrepreneurs, and which AI platforms are actually moving the needle.

Rob and Craig also chat about the realities of AI agents, the challenges of building a second product after hitting a growth plateau, and Craig’s approach to evaluating new opportunities as he looks to expand beyond podcast hosting.
