Yes. I'm not going to name drop for fear of it coming off as shilling, but I'm familiar with a couple DApps that are two-sided marketplaces for insurance on other DApps.

If you lose your money to a smart contract bug in the insured DApp, the insurers will reimburse you.

If you really trust the code of a certain app, you can earn revenue as the insurer on the other side of the trade.
