• Solo founder, $80M exit, 6 months: The Base44 bootstrapped startup success story | Maor Shlomo

  Maor Shlomo is the founder of Base44, an AI-powered app builder that he bootstrapped to an over $80 million acquisition by Wix in just six months. As a solo founder (with severe ADHD), he hit $1 million ARR just three weeks after launch and grew the product to more than 400,000 users, all while navigating two wars in Israel and never raising a dollar of outside funding.What you’ll learn:1. The growth playbook that took Base44 from three friends to 400,000 users without spending any money on marketing2. How he hasn’t written a single line of front-end code in three months—and how to structure your code repository to make it easier for AI to write your code3. His AI productivity stack that allowed him to compete against heavily funded competitors4. Why being a solo founder in AI might be the ultimate advantage (and the wedding story that almost killed the business)5. The story of signing the $80M acquisition deal while war broke out with Iran6. How to identify when to sell vs. stay independent (and why Maor chose acquisition despite being highly profitable)7. The counterintuitive product decision that tripled activation by removing a “helpful” feature8.

• I’ve run 75+ businesses. Here’s why you’re probably chasing the wrong idea. | Andrew Wilkinson (co‑founder of Tiny)

  Andrew Wilkinson is the co‑founder of Tiny, a holding company that quietly owns more than three dozen profitable internet and consumer brands, including Dribbble and the AeroPress coffee maker. Starting as a teenage barista and web designer, he’s created a portfolio approaching $300 million in yearly sales (and he was personally worth over $1 billion at one point)—all without ever raising venture capital.In this conversation, you’ll learn:1. The “fish where the fish are” framework for spotting high‑margin niches no one else notices2. The exact agent stack (Lindy, Replit, Limitless, and more) that supercharges Andrew’s day-to-day productivity (and has replaced his assistant)3. How Andrew evaluates companies in less than 15 minutes using Buffett‑style moats and “lazy leadership”4. Telltale signs you should shut down (or never start) that startup idea5. His journey from crippling anxiety to clarity through SSRIs and ADHD medication6.

The three-step process that generated names like Windsurf and Vercel2. How a name can give you the edge that no marketing budget can buy3. Why you won’t “know it when you see it”4. Why Microsoft called Azure “a dumb name” before it became their billion-dollar cloud platform5. Why polarizing opinions are the strongest signal that you’ve found the right name6.

• AI prompt engineering in 2025: What works and what doesn’t | Sander Schulhoff (Learn Prompting, HackAPrompt)

  Sander Schulhoff is the OG prompt engineer. He created the very first prompt engineering guide on the internet (two months before ChatGPT’s release) and recently wrote the most comprehensive study of prompt engineering ever conducted (co-authored with OpenAI, Microsoft, Google, Princeton, and Stanford), analyzing over 1,500 academic papers and covering more than 200 prompting techniques. He also partners with OpenAI to run what was the first and is the largest AI red teaming competition, HackAPrompt, which helps discover the most state-of-the-art prompt injection techniques (i.e. ways to get LLMS to do things it shouldn’t). Sander teaches AI red teaming on Maven, advises AI companies on security, and has educated millions of people on the most state-of-the-art prompt engineering techniques.In this episode, you’ll learn:1. The 5 most effective prompt engineering techniques2. Why “role prompting” and threatening the AI no longer works—and what to do instead3. The two types of prompt engineering: conversational and product/system prompts4. A primer on prompt injection and AI red teaming—including real jailbreak tactics that are still fooling top models5. Why AI agents and robots will be the next major security threat6. How to get started in AI red teaming and prompt engineering7.
