I disagree, there's tons of new companies adopting Solana. In terms of infrastructure, pretty recently Google Cloud added Solana Hosted nodes for next year https://cloud.google.com/ and payment platform Poof adding Solana payments https://www.poof.io/.

There's tons of other development going on with new projects launching daily. It's still early on, especially with all the DDOS attacks on the nodes. However, the future is bright.
