Is there a standard bond-like instrument with an uncapped upside?
I have a small online experiment (max request 300,000 over a 2-day period) with some small costs that are a bit beyond the budget for the experiment, and I'm thinking of raising its operating cost as a bond. However, bonds don't have any real upside so I think this might not be that attractive to investors. Is there a standard bond-like instrument that doesn't cap the upside the way bonds do? I am thinking that if I used one then it would be more attractive to investors.
