Angel investments are increasingly getting specialized. In recent years, start-ups are raising pre-seed funding before seed-stage funding. Investors in pre-seed and seed-stage companies commonly are angel investors. Majority of the angel investors prefer syndicated investments than standalone investments for the benefits that are brought in by the investors in terms of finance and diversified value-added services. But an index that gauges the robustness of the angel investments syndication by capturing its multi-dimensional aspects is not yet seen. Further, though India being third largest startup ecosystem of the world, the literature on angel investments are at very nascent stage. Hence this study aims to address these gaps by analysing the differences between these two groups of angel investors, by developing a composite syndication index encompassing multi-dimensional aspects of the syndication, factors driving the angel investment decision, in the context of Indian startups.
