How the smartest founders are winning in AI

About this video

Sam and Shaan host Jason Lemkin, founder of SaaStr and an experienced B2B investor, to explore what smart money is doing with AI. They discuss Jason’s experiment building an AI trained on 20 million words of his own content, the unexpected use cases emerging (therapy for founders, pitch deck review, sales script feedback), and broader implications of AI for software businesses—from how AI is disrupting established SaaS companies to why the next generation of founders will succeed by building exceptional software and owning their markets.

Key takeaways

• Jason built a custom AI trained on 20 million words of his content (12 years of blog posts, tweets, videos, and interviews) using Deli.ai, discovering it performs better than generic ChatGPT for specific domains and that founders use AI as a confidant for admitting fears they won’t share with humans.
• The durability assumption in B2B software has shifted: products that once guaranteed growth with 120%+ net revenue retention are now stalling at $100–300M ARR, and AI is enabling rapid disruption across previously sleepy categories like legal and support.
• Jason’s thesis on 0-to-1 startup dynamics has flipped—with AI, getting to $1M is now likely and fast (a week or two), but everything beyond $100M is under threat; success today requires shipping insanely good software and ruthlessly owning market share, not just being number four.
• Interfaces and apps as we know them are dying; MCP (Model Context Protocol) and AI agents will soon let users talk to data and workflows directly without logging into legacy software, making traditional CRM/SaaS UI differentiation obsolete.
• Jason’s SaaStr media company now operates with five employees doing $5M per employee ($25M revenue total) using AI to replace ghostwriters, designers, and content reviewers—proving that non-tech businesses can dramatically improve efficiency by automating knowledge work, though finding A-tier talent remains the bottleneck.
