Ask HN: Remote Development?

We have built Adility over the past two years, pivoted a couple of times and finally hit a nerve with our "offers cloud" api.

I worked with a developer and great team from Ukraine, but it feels we hit the ceiling with remote development, having the team not work closely together in one location (at least a couple of days a week).

Any suggestions how to make remote team work, any statistics out there on what ultimately is more successful

a) local team b) offshore c) combination

I am non technical, biz dev guy. any thoughts how that may effect our ability to grow via local team vs. offshore.
