Mike Choi wanted to work at Apple for years. Then he got there and had the moment many ambitious builders eventually hit.

Is this the thing I was sprinting toward?

In this episode of The Tech Trek, Mike Choi, co founder at Koah, shares his path from Korea to the United States, mandatory military service, Apple, Twitter, and eventually building Koah, an AI monetization company helping AI app builders create sponsored experiences.

The conversation is less about the glamour of startups and more about what founder work actually demands: making decisions without complete information, learning from Big Tech without copying it, and staying focused when AI moves faster than your team can absorb.

Practical Takeaways

• Big Tech can teach you strong operating patterns, but startups force you to build your own style.

• Founder decisions rarely come with complete data. Moving creates the next data point.

• In AI startups, speed can become a distraction if every new tool or feature changes the plan.

• Clear vision helps teams make decisions without waiting on the founder.

• Knowing when to share an idea matters as much as having the idea.
