Wow for SDR, 0.75xMRR for each demo? So if your typical MRR is $1000, you'd pay $750 per demo?
My wife used to be SDR and I seem to remember she got paid much less, maybe like 0.1xMRR.
Obviously your economics work & scale, just curious to understand how - is your close rate really high?
If an AE closes an annual deal (worth $12k in this hypothetical), and there were 4 other demos that didn't close, then you are paying $2000 to AE and $3,750 to SDRs, or almost half of your revenue on comp.
