Any one person can gift up to 14K a year to any other person. I doubt that applies to gifting to a business, check with a tax accountant. If the gift was to you personally, then you could invest the funds into the business as equity.
If the giver exceeds 14K a year to one person, there is a hefty gift tax the giver would have to pay.
Check with a tax accountant, tax laws do change they stay up on them
