Good question. We've been involved with BTC since 2013, and currently we're doing a few different things with the aim of increasing usage of the Lightning Network. We're running LSP services... https://megalithic.me/ .. maintaining some docs on the network ... https://docs.megalithic.me/ ... and running Rizful ... https://rizful.com/ .... So: while there is a little bit of revenue generated from the Lightning stuff ( see https://docs.megalithic.me/the-gentlemans-guide-to-routing-nodes/a-node-for-a-gentleman for a humorous discussion of that) ... in reality this is closer to a NON-PROFIT project which we are undertaking to find ways to increase Lightning adoption.

In the long-run these projects could be a business, but they could also just be a few little things we are trying to do to give back to the BTC community, as the BTC community has given us a lot over the years!

We're just mostly excited about the various places that Nostr and Lightning can intersect... that's why so far we've focused on zaps and zapping as the area we want to help the most with.
