Final Advice: Best Time to Build and Single-Problem Apps

AI has fundamentally changed app development. With vibe coding, agentic workflows, and modern AI development tools, what used to take 6 months to build can now be shipped in weeks. Costs are lower than ever. Speed is no longer the bottleneck.

But here’s the problem: faster development hasn’t led to better products or stronger app businesses.

In this livestream, we’re joined by Chaim Sajnovsky, Founder of B7 Dev, a development studio that has helped startups go from idea to launch for over a decade.

Chaim brings real-world experience helping founders navigate AI-powered app development, outsourced development teams, and early-stage decision-making. Together, we’ll break down why planning, positioning, and distribution now matter more than code, and why so many founders still fail even when building faster than ever.

You will discover:

✅ How AI reduced app development time and cost by 80%

✅ Why “what to build” is now more important than “how to build.”

✅ How to define your main hypothesis before writing code

✅ Why most of these features don’t drive product-market fit

✅ AI tools founders are using right now (including Claude Code)
