Siobhán O'Sullivan
Senior Negotiation Skills Instructor at Gipfelweg Ltd
16 years of experience training business professionals across Ireland and Europe in strategic negotiation, collaborative problem-solving, and relationship-focused communication that delivers real results in high-stakes commercial discussions.
From Corporate Finance to Negotiation Excellence
Her path into training came from recognizing a critical gap in how professionals approach complex business conversations.
Siobhán's journey began in corporate finance. She spent 12 years at major Irish financial institutions managing complex negotiations — the kind involving multiple stakeholders, competing interests, and high commercial stakes. That's where she saw the real problem. Professionals weren't struggling because they lacked intelligence or business acumen. They struggled because nobody had taught them how to actually prepare for difficult conversations.
Most people walked into negotiations underprepared. They relied on instinct instead of research. They pushed hard instead of collaborating. And they left meetings without clarity on what they'd actually agreed to. That frustrated her. It still does.
So she made the shift. She transitioned into training and consulting, developing frameworks based on what she'd learned in those high-pressure finance roles — but refined through evidence-based negotiation psychology and Irish business culture principles. The result is what she teaches now: structured preparation, emotional composure under pressure, and the ability to build genuinely mutually beneficial outcomes.
What drives her work? It's witnessing that moment when professionals move from adversarial thinking to collaborative problem-solving. Especially in Irish business, where relationship preservation matters just as much as commercial wins. That transformation is why she's trained over 2,400 executives across Ireland and Europe.

Why Preparation Changes Everything
Siobhán believes that great negotiation isn't about being aggressive or clever. It's about preparation. Real, thorough, strategic preparation that answers critical questions before you ever sit down at the table.
What does the other side actually want? What're their constraints? What alternatives do they have? What matters to them beyond price? Most professionals can't answer these questions because they haven't done the research. So they improvise. They react. They leave value on the table.
Her approach combines three core principles. First: understand the landscape completely before negotiating. Second: approach every discussion as collaborative problem-solving, not combat. And third: document everything clearly so there's zero ambiguity about what was agreed.
She's particularly focused on Irish business culture. The relationship aspect matters here in ways it doesn't everywhere else. Trust, personal connection, and reputation carry real weight. You can win a negotiation and lose the relationship — and in Irish business, that's often a bad trade.
"The professionals I work with aren't lacking intelligence or business sense. They're lacking structure. A clear process for preparation, a framework for staying composed under pressure, and a system for ensuring everyone leaves meetings with absolute clarity. That's what transforms negotiations."
