Assistant will convey your differentiating services to 4800 HR heads across multiple cities and nurture them for multiple months.
Even if we assume a response of 10%. i.e. 480 responses and only 1%(i.e. 48) are positive responses.
And you are able to close just 1 of those 48, ROI is achieved.
For e.g. assume Barclays has 10 positions open at any point of time.
Even closing just one of those positions gives you the ROI for the Assistant for the entire year.
Lets assume it is a Java Developer position, with ~$80K annual salary for 2-4 years experience.
Your commission from this one closure will cover the cost of the assistant for the entire year.
Generally, all our customers close minimum of 8-10 positions in first 4-6 months giving them a minimum 10X ROI.
