Building Base44: Technical Insights and AI Optimization

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 marketing

2. 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 code

3. His AI productivity stack that allowed him to compete against heavily funded competitors

4. 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 Iran

6. 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” feature

8. How building in public on LinkedIn drove more growth than any paid channel
