I built a site like that focussed around adhoc events for people of similar interests. But when I looked at the business model I saw a few difficulties: * If it was effective users would probably stop using it and switch directly to something like whatsapp * Judging by meetup, a few people actually create events and greater percentage attend. This seems common across many platforms - 5-10% of users are actually producers, but a much larger are "passive" consumers. My site focussed on adhoc events and I wasn't sure enough users would create them * The real issue was needing to promote it hyperlocally, meaning each new location needed marketing. A site focussed around groups can build a history of events for each group which aids discoverability/SEO. But a site that's all about adhoc events doesn't have that benefit in the same way if members are more amorphous (my site was all about creating e.g. an event to play tennis that afternoon, so depended on locality). I couldn't solve these issues and abandoned it. Good luck though.
