Facebook Marketplace third-party app opportunity

In this episode, I sat down with Chris Koerner and we go through a set of approachable startup ideas that start low-friction but can scale if you get distribution right. We start with a potential “app ecosystem” opportunity around Facebook Marketplace, plus a product-studio framework that combines short-form video, AI, and 3D printing to validate “dumb” products via demand before you invest. We then jump to more grounded, local-first ideas—bike washing/maintenance subscriptions, bar anti-spike stickers, and even vending-machine concepts like “shiny rock” drops at trailheads. We close with a weird Pokémon-card “meme + supply control” play inspired by the Kabuto King, including Chris’s own collecting “big reveal.” From there, I dig into why PSA-style grading feels slow and expensive, and we workshop a more modern grading experience (including a livestream/packaging angle and an AI-from-photo approach).

Key Points

• I look for “alpha” where people are already obsessing, but the market structure is still primitive (like collectibles + grading).

• I treat “distribution” as the multiplier—short-form can make “dumb” products viable if the content loop is strong.

• I push for starting manually first (prove demand), then upgrading into infrastructure, subscriptions, and scale.

• I pay attention to marketplaces with huge usage but weak third-party tooling—there’s often a platform-layer opportunity there.

• I keep coming back to “repackaging” as a business model: same underlying thing, new wrapper, new buyer, new channel.
