The Biggest Mistake AI Founders Make Today | Zain Jaffer
For years, software companies followed the same blueprint:
Raise venture capital. Hire aggressively. Sell SaaS subscriptions. Scale headcount alongside revenue.
But AI is rewriting those rules.
In this episode of Verticals, Luke and Nic sit down with Zain Jaffer, who previously built Vungle into a business that was acquired for $780M before later reaching a $4B public valuation. After investing in startups as a VC, he's now back in the founder seat building Blazel, and unlearning many of the lessons that made him successful the first time.
One of the biggest takeaways from this episode is that AI-native agencies may look like the easiest businesses to build today, but they can quickly become some of the hardest businesses to scale.
Zain explains why replacing services with AI creates an attractive wedge, but can also trap founders in low-margin businesses that become difficult to escape.
They unpack some of the biggest debates in AI right now:
-Why the traditional SaaS playbook is starting to break
-The hidden risks of AI-native agencies
-When founders should build on OpenAI, and when they should build their own models
-Why distribution is becoming a stronger moat than product alone
-How AI is changing hiring, product development, and company building
