Randomization Method
We implemented stratified randomization to assign ventures to treatment and control. Stratification was based on three elements: Continent × Traction Score (0–3) × AI Use Cases (Low vs. High).
- Traction Score is constructed from three binary indicators: whether the venture has revenue, has raised investment, and has launched a product. Scores range from 0 (no traction) to 3 (all three conditions met).
- AI Use Cases is a binary measure constructed from founders’ baseline reports. Ventures with 0–2 use cases (below the median) are coded as “Low,” while ventures with 3 or more use cases (at or above the median) are coded as “High.”
Randomization was implemented by computer, assigning ventures to one of two arms, treatment, and control, within each stratum.
We will assess baseline covariate balance between treatment and control groups using pre-treatment variables, including year founded, founder gender, venture stage, binary indicators for having investment, revenue, customers, and product launched, as well as continuous measures of investment amount, monthly revenue, team size, and years of work experience. To ensure comparability across ventures and reduce the influence of extreme outliers on the right hand side of the distribution, we will also winsorize traction and financial metrics at the 90th and 95th percentiles. At the time of registration, we have not identified any meaningful imbalances, and we will formally report covariate balance in the final paper.
