i was thinking about creating a alternative but hardly anyone is willing to pay for that now.

slack probably should be able to create a full replacement for lync, (skype for businnes).

Without an on-premise option you wouldn't be able to get in to most organisations that have Lync deployed. Feature wise it wouldn't be too hard to match, but you might go crazy trying to code Outlook/Exchange integrations.

I used to think that, too, but with the rise of cloud offerings like Office 365, many orgs are starting to see that running your own servers for Sharepoint/Exchange/Unified Communication isn't worth it anymore.

Many, perhaps, but zero of those subject to (for one example) HIPAA data sharing rules.
