I believe it is worth looking beyond just Hyperledger.

There are good arguments (I believe) why a public mainnet like Ethereum, not consortium networks, will see the biggest growth (eg consider https://m.youtube.com/watch?v=QAmNjJRtLGo which contains fantastic examples of enterprises using a public mainnet).

The Ethereum “1 million devs” initiative suggests that things like developer tooling and education could be lucrative, see more ideas here: https://seelemons.com/2019/12/08/30-ways-to-1-million-devs/
