Few people dislike making intros.
I don’t understand the reason behind it.
It could be about their reputation or guarding their networks.
I have come across many such folks.

We at Taghash got lucky.
Our customers connected us to many others.
Here in Dubai, I have had meetings with customers intros.
They opened up their contact list for the intros.
We are having trials and demos with their referrals.

We got lucky and have been making intros to our friends for jobs, fundraising, and all regularly. It feels good seeing others succeed, and you play some part in it.
