Breaking down the crowd of backers: profiling cooperative strategies on a reward-based crowdfunding platform.

On crowdfunding platforms, the success of campaigns relies on the ability of projects to attract backers. While backers' motivations have been examined, the dynamics existing among the distinct profiles of backers remain underexplored. Combining quantitative and qualitative methods, this research offers a typology of backers' profiles and shows how these profiles contribute to the success of a crowdfunding campaign. Informed by the sociological theory of cooperation, these results explain how backers with different profiles influence each other's decisions to support crowdfunding campaigns. We provide guidelines to project leaders and platforms to attract backers with the best profiles at the best moment to optimise the campaign's success strategy. We also help crowdfunding platform managers build their crowd of backers and optimise their number of funded projects. [ABSTRACT FROM AUTHOR]
