Yeah, unless they're your friends or rich uncle, these investors don't exist.
When the OP raised money, it sounds like he was still planning on going the VC-funded route, and that's the assumption investors would have been operating under.
In the end, they were probably okay with a 2-3x ROI because they expect most of their investments not to work out, and 2-3x is better than 0x. But I doubt they would have invested if the plan all along was to aim for a 2-3x return.
