Ask HN: My startup has basically failed. What now?

I've been working on a startup for ~9 months (as the technical cofounder) in the event tech space (B2B tradeshows) and I'm pretty sure we've failed to do anything productive (find product/market fit, find a problem/solution fit, learn anything valuable, etc.). We still have ~100k left but the main investors/advisors (from the 220k friends/family/fools round) pretty much feel like it's time to pull the plug. My personal opinion is that that's the most responsible thing to do (return money pro-rata) but there are simultaneous voices (paradoxically same investors) pushing to keep going (continue running pilots, building out the team [we just finally found a bd cofounder], crafting a pitch for a seed round). I don't know what to do since in my understanding we've failed at the most important thing: finding product/market fit. others on the team (advisors) believe that that's not the case and we can keep raising based on negative results. re pilots: we got 5 pilots (some paying some not) by basically being persistent and doing really really high touch sales. two of them ran this week and they were miserable failures (for every reason from poor marketing/education to last minute catastrophic product failures). absolutely all of the metrics skew heavily towards 0. i realize i'm being vague and maybe there's not enough detail in the post to give substantive advice but regardless any would be appreciated.
