"What is a capital raise? Basically, a capital raise is obtaining capital (i.e. cash money) from investors to help fund new or growing business ventures, where the investors will own a share in the business in exchange for their investment." https://www.vsag.com/how-to-successfully-conduct-a-capital-raise/
A grant isn't a capital raise. It's that simple.
