Planet Microcap Podcast | Microcap Investing Strategies

My guest on the show today is Ben Brostoff, software engineer at Klaviyo and the writer behind the Stock Talk newsletter on Substack.

In this episode, we dive into Ben’s investing philosophy—why he targets 8–10% returns with the least amount of risk, how AI is changing the way he evaluates software moats, and why he won’t own a company unless he’s written a blog post about it.
