Kickback's for team referrals?

I work for a small startup, so I want to preface this with "I am sure there are processes that exist for things like this in larger teams." (but maybe not?)

I am a Mid Market AE, and have been getting referrals from team mates outside the sales department. I feel shitty making 2k off a deal they have helped sell before I even take the call.

Do any AE's out there give kickbacks to teammates that help seal the deal?

If so, is there a percentage that is "the norm"

My sales cycle is usually 60-90 days and usually get 2k per deal.
