Socializer, a social startup based in London with research and development offices in Serbia and Slovenia has joined Supreme Factory Virtual Accelerator portfolio back in 2017. Since then Socializer team joined some interesting projects like Google Launchpad x at Huckletree and Serbian Entrepreneurs.

Petar Savic, founder of Supreme Factory joins the Socializer as an advisor in order to support their growth and help solve the loneliness issues apart from bringing networking to the next level.

Whatever the case may be, Socializer will make an introduction and set up a face-to-face conversation in a nearby location. You can use the app to search nearby people, check what they’re up to and suggest them to meet.
