There exist investment firms where some measure of return to society is incorporated into investment decisions (see e.g. https://acumen.org/). If your business is creating some sort of positive externality, then seeking these sorts of investors (whose problem interests are aligned with your company's) may be a good fit.

It sounds like what you actually want to do, however, is just create a vanilla business and put a cap on what is returned to investors. You can do this -- in fact, you can do whatever you want, the world is your oyster. The only question is if anyone will invest. VCs who want an unbounded or very large upside won't, but there exist investors who will probably waive the right to any unlikely windfalls for more certainty of low-level gains.
