Negotiation - Should I share specific numbers of my competing offer?

Negotiation can have several rounds.

• I would start keeping things vague and explain what components of the offer you care most about.
• After that, you can use the specific numbers and name of other companies as an argument for juicing the offer even more.

If you know the other company is a competitive company (there's a lot of talent flowing between them), it is worth mentioning it. This is how I was able to increase my Facebook offer significantly, at a time when they were competing heavily with Snapchat.

There is, of course, a bunch of context that may change how you approach this, e.g. how quickly the role may get filled, and how many other options you have. Negotiation Is All About Leverage
