Emotional toll, betrayal and resilience

In this episode, we sit down with Sachin Dev Duggal, founder of Builder AI and Second Brain, for his first public interview since his departure from Builder. In a candid conversation, Sachin reflects on the meteoric rise of one of AI’s most talked-about companies and the hard-won lessons from a turbulent 2025.

For some context: You might remember Builder AI — it quickly became one of the most talked-about AI startups in the ecosystem, raising hundreds of millions of dollars and promising to make software as simple as snapping together Lego blocks. But in 2025, the company faced intense scrutiny, critical media coverage, and leadership changes that reshaped its trajectory. In this episode, we unpack what really happened.

Throughout the episode, we explore:

* The "Lego" Thesis of Software: Why Sachin believed that 80% of software could be built using reusable "atomic units" long before generative AI became a household name.

* Growing Too Fast: The challenges of scaling to 900 employees and the reality of what happens when organizational governance can't keep pace with revenue velocity.

* Navigating "The Cloud": Sachin’s direct response to media narratives surrounding "fake AI" and the complexities of revenue recognition in a new category of software.

* The Psychology of Trust: How childhood experiences shaped Sachin's leadership style and the difficult realization that "wanting to be liked" can be a founder's greatest liability.

* The Captain and the Engine Room: A look at "Founder Mode" and the importance of removing layers between a CEO and their investors to maintain a single version of the truth.

* Winning the Inner Game: How the principles of professional tennis — controlling inputs over outcomes — helped Sachin survive a year of public scrutiny and personal betrayal.

* The Next Chapter — Second Brain: Why the next wave of AI isn't about reasoning, but about "meaning," and how Sachin is building a cognitive operating system to give people back three hours of their day.

If you’re interested in the raw reality of high-stakes entrepreneurship, the future of personal intelligence, or how to engineer a comeback with humility and accountability — this conversation is for you!
