Founder Execution

Patterns in how high-performing founders ship versus how struggling ones stall. Synthetic anonymized holdout page — NOT seen during prompt tuning.

2024-03-04 | The best founders ship a working version within the first 4 weeks of starting. Everyone else negotiates with the problem. Strong conviction.
2024-07-11 | alice-example shipped the acme-example MVP in 11 days from idea-clarity. That kind of velocity correlates strongly with eventual scale outcomes in my data.
2024-11-19 | charlie-example is going to struggle with the widget-co rebuild. He's a strong engineer but I don't think he's willing to ship the rough version. Moderate conviction, ~0.6.
2025-02-28 | The fund-c portfolio's median time-to-first-paying- customer is too long. I bet they re-rate down at next mark-to-market.
2025-05-15 | charlie-example proved me wrong on widget-co. The rebuild shipped faster than I predicted and the architecture choices look strong. Good update on my prior.

I think alice-example outperforms her seed projections by year 2.
I bet at least one fund-c company hits a meaningful revenue milestone by mid-2026 despite the slow start.
