Portrait Nina Siessegger by Meike Kuether

About me

Change requires clarity - and the courage to leave familiar paths.

I support organizations and leaders in evolving - effectively, with agility, and in a sustainable way - even when the challenges are complex. I look at patterns, dynamics and interdependencies, and help to work with them in practical ways.

What drives me: I believe in the power of participation, in asking better questions instead of delivering quick answers, and in creating work environments where growth is possible - for people and organizations alike.

What defines me

I bring nearly 20 years of experience in the digital space - across editorial teams, software development, startups and technology consulting. Today, I draw on these perspectives in my work as an organizational consultant, mediator and sparring partner for leadership.

I take a broad view of organizations - from strategic context and structures to everyday collaboration.

I enjoy working with organizations that want to grow without losing themselves. That are curious about real change. And that are ready to share responsibility and rethink how they work together.

Who I work with

I work with organizations that have the courage to rethink collaboration - whether they're tech companies, mid-sized businesses, public institutions or mission-driven organizations.

What connects them isn’t a specific sector, but a shared mindset: They want to shape change consciously, involve people in the process, and create structures that allow development - for their organization and everyone in it.

I support:

  • Tech companies in building effective teams and structures
  • SMEs in clarifying responsibilities and enabling modern collaboration
  • Social and public organizations in becoming more future-ready, participatory and agile

How I work

  • Big-picture & participatory: I listen closely, ask questions, uncover patterns - and create spaces where different perspectives can be heard and used.
  • Agile & pragmatic: I work iteratively, with lightweight methods, and support change in ways that are actually applicable in daily work.
  • Tech-informed & team-oriented: With a background in software development, I understand the reality of technical teams - and what they need to collaborate effectively.
