I am not sure whether this is what you're looking for but couchsurfing may be a starting point:
as they claim on their website:
Couchsurfing is a global community of 14 million people in more than 200,000 cities who share their life, their world, their journey. Couchsurfing connects travelers with a global network of people willing to share in profound and meaningful ways, making travel a truly social experience.
Hope it can be useful for you!
Also look at this question. It may help:
Is there an online community to find travel partners (for mountains, sightseeing etc.)?
