There are a number of licenses that do this. And yes, many of them are not OSI approved and people will say mean things about not using the word open source. Which you should ignore and instead perhaps say fair source instead if you care.
a public LICENSE that makes software free for noncommercial and small-business use, with a guarantee that fair, reasonable, and nondiscriminatory paid-license terms will be available for everyone else

I also recommend going through the back log of posts by Kyle Mitchell, an engineer - lawyer who has authored a number of great software licenses, including the two I listed.
