What you have there may not actually be a "zombie startup"; projects like yours were once known as "businesses", although that's a term that's fallen out of favor in the last internet-decade ("calendar year") on post-modern journalist hubs like TechCrunch and community forums like HackerNews. I quickly went over to my "bookshelves" and dusted off some ancient collections of business knowledge, and it seems that, prior to the current internet-decade, the classical advice was to simply continue operating, looking for slow, steady growth, and enjoy having your own "business" rather than working for someone else. Clearly, this sort of advice isn't valid anymore; if a startup doesn't lead to a $100 million dollar exit in 3 years, then it has failed and just doesn't know it yet. I think most startups would advise you to abandon your customers and build a social network, as those seem to have good odds these days of leading to success ($100m in 3 years).
