Gainful raises $7.5M for personalized sports nutrition

Gainful, a startup offering personalized subscriptions to protein powders and hydration products, is announcing that it has raised $7.5 million in Series A funding.

COO Eric Wu, who founded the company with CTO Jahaan Ansari, told me that Gainful began with his own experience experimenting with different protein powders and eventually finding the combination that worked best for his goals and dietary needs.
