How can I grab a guy's (who I met once, briefly) interest?

Hey!

I recently joined a new church after moving states and met a bunch of new people. I was introduced to this guy, and I think he's really cute.
I was not able to really talk to him or get any contact info cause I had to leave shortly, but I'd love to get a chance to know him.

What are your tips?

We do share a mutual friend, who I guess I could ask to "set us up" or what not, but I'm not sure if that would be a good route in the case that he may not be interested... I would not want an uncomfortable situation going forward, ykwim.

My friend did say that he has an instagram, and suggested that I send him a follow request. However, I'm not sure if that would come off as creepy or weird.
