|---|---|---|---|---|---|---|
| Founder Pitch: ShipperMax | 5 | 6 | 2 | 6 | Paul probes Jenna on whether ShipperMax has actually won and executed deals or just received pricing requests. Jenna effectively educates Paul on how industrial bulk shipping brokerage works and why data intelligence drives commodity trading allocations. | |
| Sam Altman Re-Pitches ShipperMax | 4 | 6 | 1 | 5 | Sam models how to pitch the marketplace concept cleanly, fielding Paul's simulated investor pushback on incumbent brokers and customer inertia. Sam deftly reframes the business as a human-assisted software platform analogous to Palantir. | |

| Founder Pitch: My Purple Folder | 5 | 3 | 3 | 7 | Paul repeatedly pushes back against abstract analogies and long storytelling, demanding a clear, direct answer about what the product actually does.

| Sam Altman Re-Pitches My Purple Folder | 5 | 5 | 1 | 4 | Sam demonstrates how to ground My Purple Folder's pitch in clear macroeconomic problems and a simple consumer value proposition. Paul engages with standard seed-stage investor questions regarding customer burning problems and willingness to pay. |
