On the podcast: why founders belong in the marketing trenches more often, what makes ‘ugly’ ads perform so well, and why stable ad performance is actually a red flag.

Top Takeaways:

🚨 Stable ad performance is a warning sign, not a win 
A $30 acquisition returning $50 can feel safe enough to scale, but that comfort may stop the search for the breakthrough creative that halves CPA or triples purchases.

👀 Ugly ads earn the attention that polished ads lose
When every feed looks perfectly branded, an unpolished ad that explains the product in the first second has a better chance of stopping the scroll.

🛠️ Founders cannot outsource market intuition
Sitting in acquisition meetings and developing early creative gives founders a firsthand understanding that no agency or marketing hire can manufacture for them.

🧪 Validate demand before building the product
Selling a PDF, concept, or promise—even if it must be refunded—is a cheaper test than spending months building an app the market never asked for.

🌍 Localization is a testing advantage, not just a translation task
Similar-converting international markets can turn a $1,000-a-day US creative test into a $10-a-day experiment, provided the team still accounts for local culture.
