Where’s the incentive for quants in open competitions?

Periodically I will find an open competition for quants to develop and submit original strategies in an open competition, and typically, the reward offer is something like 10% of the profit generated from the strategy after a large institution has put it into production. Like this one: https://www.businesswire.com/news/home/20180829005809/en/CloudQuant-Announces-Record-Year-Growth-new-Licensing

I'm having trouble seeing why someone would take this offer, it just doesn't seem like enough incentive, versus just running the strategy quietly by myself.

I realize that being under-capitalized is often an issue for traders, and that a 10% cut could be a really handsome profit in a short amount of time, but wouldn't it make more sense to shop the results around with some friends and family so I could dictate my own cut and get a better deal for myself? Or is the issue that most quants don't have the technical chops to harden and deploy the strategy to a live account?
