Venture debt. Though, unless you have no other options, I wouldn't do it; angel investors are better in almost every way, and they can't forcefully liquidate your company when they feel like you've been underperforming.
I'd rather have the possible threat of liquidity than the guaranteed loss of equity.
Angel investors.
Angel investors generally make equity investments, not loans. Cohost in the past has been very specific about the fact that their funding was the latter.
