Casa was a major contributor in the early days. In addition to the Casa Node, they produced SatsApp that rewarded node runners for pinging their node daily (10k sats/day, IIRC) and provided a user-friendly identifier to receive LN payments called a SatsTag (similar to Lightning Addresses but only available through SatsApp).
They have pivoted to plugging in ETH and, recently, stablecoins, so it counts. I remember their weird nodes with old RPi and additional cable.

Ethereum was available in Keymaster (the original name of the Casa multisig app) back in 2018, before the original Casa Node was released:
Looking back, it’s more like they temporarily removed it rather than pivoted. But all of that is unrelated to the fact that they ran SatsApp to incentivize early LN nodes to stay online, and that the majority of LN nodes on the network were probably Casa Nodes for a while (definitely the majority of tor nodes).
