Janna Lingenfelder - Your Negotiation Strategist
Janna Lingenfelder – negotiation strategist, trainer, and creator of the APEX® Negotiation Map – at your side.
I support professionals and leaders in STEM and technical fields in systematically developing their negotiation competence, achieving goals, and securing sustainable results.

The right format for your situation
You learn negotiation best in the way that fits your context – through interactive group training, individual consulting sessions or an inspiring keynote at your event.
Training
Intensive formats for professionals and leaders who want to develop their negotiation skills systematically and practically – from the basics to strategic mastery.
Negotiation Consulting
Individual support for your critical negotiations, from analysis to strategy to reflection. Tailored precisely to your goals and organizational context.
Keynotes and Talks
Impulses on negotiation psychology, power and ethics or gender dynamics – compact, inspiring and ideal for conferences and leadership events.
Mastering Negotiations with Structure and Clarity
With the APEX® Negotiation Map, I provide you with a clear and structured framework. You learn to see through complex situations, recognize underlying patterns, and shape negotiations strategically. The result: greater clarity, confidence and influence at the table.
What you gain with the APEX® Method
- Your negotiations follow structure rather than chance — turning objectives into results.
- Uncertainty turns into strength, reactivity into strategic action — and your technical excellence is complemented by composure and confidence.
- You grow into a negotiator who not only argues, but leads.
- You gain what no tool can give you: the ability to negotiate and lead with clarity and impact at decisive moments.

The Hidden Dynamics of Negotiation
You’re technically skilled and analytically sharp – but negotiations have their own rules. Logic and data don’t always decide the outcome. Power, relationships, psychology, and other hidden forces often make the difference – that’s where I support you.
