Anyone using SDR type roles on your Success Teams?

I am looking to hire 2 new Success Development Representatives to assist the Success Team in making proactive engagement outbound calls to our current large client base. This will be a brand new role and will not be a part of Sales but will execute cross-sell initiatives as well as promote focused action items for our current clients. Is anyone using SDRs currently on their Success teams? I would love to connect to see what you did during the recruiting and training phases!

Thank you in advance!
