There is a relationship of synergy/ (synergistic relationship) between concept A and concept B working together.
A synergistic relationship is one where two parties, or things, working together, are able to produce a result that is greater than the sum of what they can each do individually.
It is perhaps OED sense 3 of synergy which seems relevant here:
- Any interaction or cooperation which is mutually reinforcing; a dynamic, productive, or profitable affinity, association, or link.
