This is a fantastic project. I also briefly worked on something similar, but left when I learned more about my coworkers.
Bootstrapped, COVID hit right before the launch date.
Infra costs were ~$200 a month to support 10k DAU. I'd just come off of working on embedded, so I was used to writing really efficient code. :)
> At what scale would you be able to support your burn rate?
Just needed to cover my living expenses mortgage and salaries!
Obviously to scale money was needed for ad campaigns, but people are lonely and offering to solve loneliness has a high conversion rate!
I burned through my savings and was ready to launch in earl 2020.
Oops.
Yeah the final end goal was either to make lots of deals with local businesses (hard to scale) or to license an ML personality matching model to companies.
The app had a handful of personality questions that I copied over from research done at one of the Nordic universities (I forget which one) on what makes people get along together in a casual setting. The American universities have mostly done research on group cohesion in corporate settings, which maybe hints at what is wrong with American society at large!
Cruise liners and casinos would pay a fortune to know what guests would vibe together.
I had a partner website that allowed for self onboarding, but of course b2b2c is never that simple. :)
The operating costs were so absurdly low (~$200 a month per city it was running in) that letting people create their own events for free was in the near term road map, no reason not to.
No photos until just before the event started, because photos turn things into a beauty contest and people start judging on looks, which is where, IMHO, all my competition in the same space went wrong.
Events were scheduled for as little as 4 hours out, and only up to 72hrs in the future. The entire app flow was designed to be as close as possible to a "I am bored, entertain me now" button.
Investors hated it, two sided marketplaces are apparently something they like to avoid due to difficulties around execution.
People were desperate for this type of service though, for one marketing campaign my user acquisition cost dropped as low as 15 cents per user.
