Jens Thiemann

Organizational & Leadership Designer

If your structures, decisions, and collaboration already work with and without AI, you don't need me. If not, let's talk.

Book a Conversation

Jens Thiemann portrait

Computer scientist. Founder, product manager, and business unit head by experience, including orchestrating 150+ developers. Today I help leaders design how their organization actually works: structures, decisions, collaboration, and yes, AI.

Organizations grow. Complexity grows faster.
AI adds opportunity, but also confusion.

Structures That Don't Scale

Teams grow, but structures stay the same. Responsibilities blur, collaboration gets harder instead of easier.

Fragmented Collaboration

Silos, friction between teams, and structures that make it hard to work across functions. With or without AI.

Unclear Decision-Making

Slow, political decision-making, endless meetings, and confusion about who owns what. Meanwhile, AI accelerates everything around it.

How I Help

I combine organizational design, leadership practice, and technical depth to help organizations work better. Simpler structures, clearer decisions, and AI where it actually helps.

Organizational Design

Design structures that support learning, clear ownership, and cross-team collaboration. Instead of getting in the way.

Leadership Design

Shape how leadership actually works: who decides, how information flows, and how AI supports rather than replaces judgment.

AI Integration

Nobody has built the AI-powered organization yet. I help you start where you are. Not just throwing tools at the problem, but integrating AI in a way that actually moves your organization forward.

My work draws on and contributes to modern approaches like unFIX, Management 3.0, and M3K. It integrates systems thinking, network theory, and complexity-informed perspectives. I use these as tools, not templates.

With years of experience building master data systems (PIM/MDM), I know that AI is only as good as the data behind it, and what it takes to build a solid data foundation.

How We Work Together

20+ years of building, leading, and redesigning organizations. I know how hard it is to make change stick. Every engagement is different, but the approach is always the same:

1. Understand

Short call to clarify your context, key challenges, and what "better" would look like for you and your organization.

2. Collaborate

Co-create a simple, pragmatic design for structures, leadership routines, and AI integration. Tailored to your reality.

3. Learn & Scale

Start Small with one area or leadership group, learn from it, then scale what works across teams and departments.

This can take the form of workshops, leadership offsites, ongoing coaching, or a focused advisory engagement.

I've been coding since school, and I still do. These days with AI as my co-worker.

Leadership is serious work. That doesn't mean we have to take ourselves too seriously.
