Well, hopefully this won't turn into a "customs vs universals" thread, or a "high-end customs vs high-end universals" thread.
While there are indeed many new customs start-ups, it's also true that the customs craze isn't quite what it was 1-2 years ago. On the other hand, these days you also get pretty cheap customs, so the possible disappointment for people who opt for these cheaper customs isn't nearly as hard-hitting as it was only a few years back.
When I started the (now locked) "Are (High-end) Custom IEMs Overrated?" thread 4 years ago, I got several PMs from people who would tell me in private of their own horror stories, or simply that they were underwhelmed, but said they would not post their genuine thoughts for a number of reasons, namely they wanted to sell their customs (usually at a huge loss) and didn't want to openly say their customs weren't quite what they'd hoped they'd be.
Take, for instance, the Future Sonics MG6Pro: Not many Head-fiers own these customs, yet I know 5/6 people who were very disappointed with the sonics of this $1,000 pair of customs, yet none of these owners posted their genuine thoughts on the MG6 Pro thread; they might have said a thing or two here and there, or merely hinting they regretted their purchase, but never openly said what they said to me in private or what I saw written in other non-MG6Pro threads. If you visit the dedicated MG6 Pro thread and read the whole thing, you'll mostly (95%?) find glowing impressions. This, btw, is one custom IEM that has zero re-sale value as it cannot be re-shelled.
I got PMs about not so great experiences with JH Audio, 1964 Ears, UM, UE re SQ, poor QC, CS, multiple re-fits, shipping charges, long wait times, or simply being underwhelmed by the not so spectacular sonics these people had come to expect. There's more even.
Yes, ideally, one should do (quite) a bit of research, but it often proves an almost impossible task with soooo many threads, many of which are exceedingly long with endless irrelevant posts, and mostly populated by fanboys of guardians of their favourite toy. Yet, even when we haven't had a clear, balanced, accurate picture of the negative aspects of customs, it seems that even those not so few reported cases have had an impact / influence as more people seem to be aware of the fact that customs aren't necessarily the answer to great sound in IEMs.
The fact we're seeing more and more customs turned universals already says something of the changes in the customs craze trend I spoke about earlier. Only today the German-made Stage Diver SD-3 went on sale for about $550 here in Europe.
I'm sure you and many others get goose bumps with their customs, but many, many people also get goose bumps with their $100 / $200 / $500 / $1,000+ universals.
I know it's not only about earning since there are people who will easily spend £200 on a meal or a night out, a piece of clothing, etc.
Yes, like I said in my previous post when I spoke about people exaggerating the sonic merits of their customs: "... sometimes said exaggeration is simply the result of a different sound signature, much like many sound sigs found on cheap / expensive universals"
