Negotiations. Conflict. Be Prepared.

ISMAN & Partner: Negotiation Expertise and Conflict Resolution at the Highest Level

Since 2015, we have been supporting organisations worldwide in leading complex negotiations with confidence and resolving even highly escalated conflicts professionally and effectively.

Founded by Mihai Isman, a Harvard-certified negotiation expert, university lecturer and intercultural mediator, ISMAN & Partner stands for tailored, strategically grounded solutions rather than standardised approaches. Together with our network of experienced partners, we develop negotiation strategies that help leaders succeed when the stakes are highest.

Our clients work in key functions such as Sales, Procurement, M&A, Contracting, HR and IT. What they have in common is the need to make important decisions in fast-moving, high-pressure environments where complexity is the norm. This is where we bring structure and practical solutions that enable confident action.

What sets us apart

At ISMAN & Partner, there are no off-the-shelf solutions. Every coaching engagement, workshop and conflict intervention is carefully tailored to your objectives, your organisational context and the specific dynamics you face. The result is support that delivers not only immediate impact but also lasting value.

How we work

Every engagement begins with a thorough assessment of your situation: Where do you stand? What do you need to achieve? Which dynamics are shaping the negotiation or conflict? Based on these insights, we design tailored interventions that are pragmatic and firmly focused on results. Our role is to create the clarity and strategic direction that enable confident decisions with sustainable outcomes.

Why ISMAN & Partner

We combine expertise in negotiation, mediation, business, psychology and organisational development with many years of experience advising leaders in high-stakes situations. Our hallmark is strategic depth combined with pragmatic execution. We deliver substance without unnecessary complexity and focus on solutions that create lasting impact. Whether through executive negotiation coaching, exclusive team workshops or the support of highly complex negotiations and conflicts, we help our clients achieve outcomes that are strategically sound, and professionally robust.
