We are bootstrapped, which means that since we started Kiwi almost 1.5 years ago, we invested our savings to make it work.  So far we have made money in 3 ways: 1) By selling Passes that let people use our app, 2) By receiving grants from Optimism, Gitcoin, Warpcast, and Purple, 3) By organizing writing contests with projects such as Gnosis and Lens.
