Curious. What are the differences in features being asked?
Startups want a JavaScript version so they can use it in-browser. And they are more interested in full-text search than other types of queries.
Enterprises are big on integration with existing stuff (Microsoft SQL Server, SharePoint, etc.) and using it as a CASB-esque solution.
You should aim to build only enough to close a sale. IF you build the in-browser features will that ACTUALLY close them? And that calculus should include this: Will it close enough SMBs that it counteracts doing a single integration with an existing system that will close 1 big customer.
More than that: when end-user is SMB but paying customer is a B2B cloud software vendor, needs are often the same as for startups.
Basically, end-to-end encryption for client (browser, mobile) software vs protecting backend software which uses some flavor of SQL
