I got some java contracts in my consulting company, some of them are startups. If you are building a SPA you should check out JHipster, they have plenty of information on why they chose certain tools over others.
If you are building a normal, server-side rendered app Spring-boot+data+mvc and thymeleaf (or freemarker) are usually what small companies use for fast development. Investing into IntelliJ Idea is really helpful.
There is no need to rewrite. What exactly is taking long in the development? Maybe I can help with some tips (I'm SCEA/SJCP/etc)
Edit:
> there would already be a dozen open-source versions we could use or adapt quite easily.
That never materializes into actual usable products.
