Honestly, I do not know if consortium blockchain solutions will succeed or blockchain will be rather the field of public permissionless blockchains. But if consortium blockchain is a use-case, big companies will buy them from enterprise IT vendors, like Microsoft, IBM, Oracle, Hyperledger ...
Nobody will buy a consortium blockchain platform from a noname startup. Not because the technology is not good enough, but simply this is how enterprise IT buying decisions work. This has to be taken into consideration at every development decision that tries create a consortium blockchain solution. Certainly, strategical directions can be
- we are good enough to compete with these corporations (and have enough capital as well),
- we build up the company to sell not directly to the end customers bot to these enterprise vendors, which might be a little bit tricky if the company was financed by an ICO
- we find a niche market among these enterprise vendors
