Built for the 48 hours before the call
Counterspar is a kemero product. Paste a real offer, spar the person on the other side, and leave with a graded scorecard plus a counter-offer email and phone script that already survived contact.
kemero operates Counterspar. Kenny Damgren built it and writes the guides.

Founder of kemero, a web agency in Västerås, Sweden. I have built for the web since 2013. Counterspar is one of the products kemero ships. The same person who built it answers when you write support.
The guides and the product stick to standard negotiation doctrine: one number, one reason, trade instead of concede, silence after the ask. Counterspar is a rehearsal partner, not a licensed advisor. The judgment on the real call stays yours.
Why this exists
The person across the table negotiates weekly. Most candidates negotiate a few times a decade. Articles and templates help you pick the words. They do not make you survive the second sentence when the other side pushes back. Counterspar closes that gap with a live round built from your actual offer.
