Even more, this has implications not only when searching for jobs or gigs, but also on the social/personal level: the stigmata and marginalization that comes with it it's incredible here.
US employer here (who all hires for some EU-based roles): I view failed entrepreneurs very positively, assuming the candidate can reflect reasonably on what went well and what went poorly.
I think it varies quite a lot across countries. I don't think it would be a problem being a failed entrepreneur in the Netherlands.
I had two belly flops, two marginal and one boring startup under my belt before I took on the latest one. I have never met any stigma in the Netherlands, UK or Sweden. The last two are of course not mainland Europe, but anyway.
