|---|---|---|---|---|---|---|
| Josh Breinlinger's Journey from Engineering to Venture Capital | 3 | 3 | 2 | 1 | Harry demonstrates preparation by quoting Josh's past blog post on data-informed versus data-driven investing.

| Evaluating Startups: Team, Product Shift, and Data Validation | 4 | 2 | 1 | 2 | Josh outlines his investment framework of team, product experience, and data validation using ScriptDash as a case study. Harry demonstrates industry insider knowledge when he calls out top VC firms claiming to lead rounds while putting in minimal capital. | |
| The Rise of Master Marketplaces and Evaluating Market TAM | 4 | 3 | 2 | 4 | Harry pushes back on Josh's master marketplace thesis by asking whether deep specialization results in a total addressable market that is too small for VC returns. Josh reframes the issue by explaining how master platforms leverage expert time across vertical-specific TAMs. | |
| Marketplace Dynamics: Transaction Size, Frequency, and GMV Quality | 3 | 4 | 2 | 3 | Josh criticizes flawed marketplace concepts like Uber for locksmiths due to low transaction frequency.
