What is a word for 'ability to form relationships'?

Question

I'm writing a paper on a company need a single word to describe the companies ability to form strong relationships with its investors and customers.

Answer 1

consensus-building

Here's an example:

"When Jane Smith Industries went public ten years ago, corporate officials set in motion a strong, consensus-building investor services model that is also palpable in how they relate to their customers."

Answer 2

Rapport-building (if you hyphenate it will be one word)

or liaison but it doesn't have the same feel you need 2 words with an adjective modifier.

Answer 3

maybe the word "empathy"
