01 THE IDEA

Jonathan casually drops one of the most actionable pieces of advice in the video: go to the Facebook Ad Library, type in your competitor's name, click their ads, and follow them into their funnels to see what's working in your industry. This is currently a completely manual process. A SaaS product that automates this — monitoring Facebook/Meta Ad Library for a user-defined list of competitors, screenshotting funnel pages at each step, tracking how long ads have been running (a proxy for profitability), and notifying users of new campaigns — would be enormously valuable to any marketer building funnels.

The product could integrate with the public Facebook Ad Library API, use headless browsers to follow click-through paths from ads to landing pages, and build a searchable database of funnel structures by industry. Monetization could be via subscription tiers based on number of competitors tracked and depth of funnel capture. Positioning as 'funnel competitive intelligence' rather than 'ad spy' would differentiate from existing ad spy tools that focus on creative assets rather than the full funnel flow.

03 THE VERDICT

There is a clear gap in the market: existing ad spy tools capture creatives but not funnel flows, yet the full funnel structure is where the real competitive intelligence lives. The Meta Ad Library provides a legitimate public data source, reducing legal risk versus scraping-only approaches. With strong recurring revenue potential, high automation scores, and a technically achievable MVP, this is a compelling SaaS opportunity. The main risk is platform API access changes, so building multi-platform support (TikTok, YouTube) early would provide resilience.
