I'm seeing a lot of new Bitcoin wallets popping up left and right (Nayuta, Mash, etc.). Some developers build companies around their dev team and seemingly work with an expectation to get paid, but how do these companies make money? Just thinking about the lightning wallets I use like Muun, Mutiny, Phoenix, and Wallet Of Satoshi, I don't know what their end game is with regard to monetization. Does anyone know how these companies are planning to stay sustainable in the long run? Are any of them backed by VCs with an expected ROI?
*I focused on lightning wallets in my examples because a good amount on-chain ones seem to have some sense of their desired monetization strategy (Wasabi has coinjoin fees, Nunchuck has subscriptions, Green has Jade, Liana has subscriptions, etc). Please feel free to add input to on-chain companies as well though. Also, some Lightning companies have LSPs so there is a sense of monetization strategy in that department.
