Partner session

What it is

A partner session is a controlled, simulated conflict. Partners walk through future scenarios in advance — failure, runaway success, one partner leaving, a crisis — and agree on what to do while the relationship is calm.

Who it is for

For co-owners who are starting a joint business, bringing in an investor or an heir, going through a disagreement, or want to put rules that already exist in writing.

The result

The result is a partnership agreement: a clear, unambiguous document that fixes equity, roles, control, money and exit terms for every scenario. Sessions run in person or online, in English, Ukrainian, Spanish or Russian.

My Clients

Stories

I do not discuss information received during individual meetings with other partners or third parties.

Partnership agreements are the main asset of business partners, and I only work with them after signing an NDA. I prefer not to advertise my awareness of these issues when discussing delicate, sensitive aspects of business and forming agreements.


Partnership agreements, like money, love silence
