This article documents the fact that ventures funded by two successful angel groups experience superior outcomes to rejected ventures: They have improved survival, exits, employment, patenting, Web traffic, and financing. We use strong discontinuities in angel- funding behavior over small changes in their collective interest levels to implement a regression discontinuity approach. We confirm th…
