I Spent 24 Hours With iOS Millionaires

Pat Walls visits Cal AI co-founders Blake Anderson and Zach Yadegari in New York (the other two co-founders, Jake and Henry, join by FaceTime). They cover the founding team, revenue ramp ($30K first month to $1M/month within 8 months, ~$50M/year run-rate), declining low-eight-figure offers in late 2024 before an undisclosed sale, the size of the App Store opportunity, copycat vs differentiated apps, and their new projects (10x App Builder, Flow). No Cal AI acquisition tactics are discussed.
