Why Your Product Trio Is Actually Waterfall in Disguise (Product Lead)

Product managers who vibe code. Engineers who make product decisions. Designers shipping prototypes without handoffs. The roles are blurring, and it's not just because AI makes it possible - it's because staying in your lane might be what kills your company. Else Van Der Berg has been crossing domains for 15 years, and now she's watching the convergence accelerate at AI-native companies like Wave Terminal and SwitchUp.

In this episode, we explore why natural convergers have always existed (but were told to "stick to their lane"), how AI-native startups are staying impossibly small while scaling revenue, and why product-market fit collapse means every company is pre-PMF again.

GUEST

Else Van Der Berg - Product Lead & Solopreneur

Else has 15 years of product experience and currently works with two AI-native companies: Wave Terminal (an AI-native terminal and dev tool) and SwitchUp (AI-native internal tools). She's spent the past nine months vibe coding, building AI agents, and exploring the convergence of product and engineering firsthand. As a "natural converger," she's been pushing domain boundaries long before it had a name.

KEY TAKEAWAYS

1. Natural convergers have always existed - that 1973 journal proved developers worked directly with clients. We artificially specialized and now we're going back.

2. AI-native companies are the new anti-flex - Cursor: $100M ARR with 12 people. Mid-Journey: $200M ARR with 40 people. Growing headcount isn't cool anymore.

3. Product-market fit collapse is real - Stack Overflow got destroyed overnight by ChatGPT. Every company is pre-PMF now because AI competitors can appear instantly.

4. The handoff tax is more expensive than learning - product trios sound nice until the developer can't make the interview and the designer is "too busy with sprint work."

5. Delivery is discovery now - at Wave Terminal, they shipped a full app builder in 3 weeks just to validate if people would use it. Building is cheaper than talking about building.
