I had extremely limited visibility into my market value, so I hired Josh to help me negotiate.
Working with Josh was excellent! Having a professional involved allows me to not overthink and overanalyze the process. I can throw out ideas, have them approved or not, without having to spend hours and hours agonizing over the decision tree.
With Josh’s help, I negotiated $30k more salary, $50k more bonus, and $100k more equity.
I always try to convince folks to hire Josh. The biggest obstacle is that (IMO) people are irrationally cheap or over-value their own negotiation skills. I consider myself above average at negotiation (and some of that was learned from Josh and his book), but I would still much rather have the guidance of a professional to get the max comp offer and peace of mind.
