Interesting approach. Would you share how many people you have on staff? Do you have any certifications?
Yes, we've managed hundreds of salary negotiation with varying companies and roles. So we've become the leader in this space by using a data-based negotiation approach.
This isn’t an answer to the questions posed.
The staff consists of the founder, negotiating team, and contractors/services to help with other functions of the business. As for certifications, I'm not sure of the exact certifications you're seeking.
