About me

Theresa Tenneberg

Who I am

My name is Theresa Tenneberg.
I support companies in reshaping their business models, turning innovations into market-ready solutions, and enabling sustainable scaling – with strategic foresight, strong leadership, and deep expertise in digital transformation.

What shapes me

For 20 years, I’ve been working at the intersection of strategy, technology, and organization — with a clear focus on implementation and impact. What sets me apart is clear analysis, operational responsibility, and the ability to lead organizations through complex changes — with a focus on people and a clear focus on results.

These transformations are often triggered by periods of upheaval: strong growth, revenue slumps, acquisitions and integrations, regulatory changes, or increasing competitive pressure.
It is precisely in these moments that I take on responsibility – both strategically and operationally.

My path

  • Studied business administration at the Humboldt University of Berlin
  • Five years as a consultant at Roland Berger, reorganization, efficiency and commercial due diligence projects in industrial medium-sized companies, for corporations and investors
  • Ten years at TÜV SÜD, in corporate strategy, innovation and later as Chief Digital Officer of the Industry Services Division
  • Strategic development of over 10 business areas, focus on global growth strategies, digitalization and AI
  • Move to a private equity-led SaaS company as SVP Product & Software Engineering, and business unit manager – with responsibility for product portfolio strategy, platform development and management of the product and development teams
  • Since 2024 self-employed – as an interim executive and business developer with clear responsibility for results

I am also a certified business coach – which complements my work as a sparring partner for management teams and decision-makers: with focus, clarity and dialogue at eye level.

What drives me

I believe in the potential of organizations to achieve more – when structures are clear, products are relevant, and leadership is effective.
I’m not just interested in strategy, but also in what drives it in reality. I enjoy working in systems that need
to change – and helping them do so .

Digitalization and AI offer enormous potential – both economically and socially. I’m driven to finally harness this potential.

Selected stations and projects

  • Interim management of a software unit: Developed a sustainable business model, established product management, market development and drove the transformation from a hardware to a solution provider
  • Interim task force management at an electronics manufacturer: Responsibility for a company-wide reorganization, cost reduction and change management program
  • SVP Product and business unit management in a PE-led SaaS company: P&L responsibility, developed product portfolio strategy, launched three new platforms, reorganized product team, increased revenue by 30%, reduced R&D costs
  • Chief Digital Officer at TÜV SÜD: Led global strategy, innovation, and transformation program for the Industrial Services business, developed over ten digital services in the areas of AI, Cloud, IIoT, and Cybersecurity
  • Strategy and Innovation Manager at TÜV SÜD: Developed international growth strategies for industrial and service sectors
  • Consultant at Roland Berger: Supported restructuring, efficiency improvements and performance improvements in industrial medium-sized companies, corporations and for investors

What makes me who I am

  • Deep experience in digital business models, platform and software development
  • Strategic clarity combined with operational leadership responsibility.
  • High effectiveness in phases of transformation and change – even under high pressure to achieve results
  • Attitude, reliability – and the ability to truly lead change
  • Broad industry knowledge, especially in industrial sectors (mechanical engineering, energy, construction), B2B, software/IT
  •

What others say about me

Theresa coached me through my first 6 months as VP of Product at a new company, and working with her gave me the confidence and clarity I needed to succeed quickly. She was instrumental in helping me craft a 30-60-90 day plan that prioritized high-impact wins while I navigated the complexity of a new organization.

I appreciated Theresa's thoughtful approach to bridging the gap between strategy and execution. Her guidance was critical as I established new processes, prepared for my first board presentations, and structured the team for growth. Her coaching allowed me to accelerate my ramp-up time and establish trust with stakeholders much faster than I could have alone. I highly recommend Theresa.

Emily Wanless

Vice President Product @ SaaS B2B company

We have worked with Theresa twice during critical phases in our company: first as part of an important organizational development process, and later to support the build-up of our software business. In both mandates, she initiated significant changes with great clarity, structure, and strong execution. At the same time, she strengthened our leadership team and encouraged entrepreneurial thinking. Together with our team, she laid the foundation for a viable software business – with a clear business model, a structured product management approach, and an integrated go-to-market concept. I value Theresa for her strategic strength as well as her ability to address complex topics in a pragmatic and solution-oriented manner. Working with her was extremely valuable – I would engage her again at any time.

Sonja Wiedemann

CEO & Managing Shareholder @ Sensor-Technik Wiedemann

Working alongside with Theresa for four years, both of us reporting directly to the CEO of a €600M+ business division, has been one of the most inspiring and professionally rewarding experiences of my career. She is the rare combination of hands-on pragmatist and visionary leader — someone who not only sees what's next but knows exactly how to get there. As an example, together, we conceived and launched a groundbreaking digital service for the Energy Industry — a completely new category of offering, both in terms of business model and technical architecture. Under her strategic leadership, this innovation not only achieved an exceptionally high operating result but also set a new benchmark for digitalization in a highly traditional industry. It was bold. It was complex. And she made it happen. What impressed me most? Her ability to translate abstract strategy into executable action — quickly, decisively, and collaboratively. She moves seamlessly from Board-level discussions, building long-term company development strategies, to operational implementation, always with a strong sense of purpose and integrity. In a global matrix organization, she is a great to have senior servant Leader. Would I recommend her? Without hesitation — and without limitation. Any company serious about driving innovation, navigating digital transformation, integrating AI in daily business or shaping long-term strategic growth would be lucky to have her on board as part of the Leadership team. She's not just an experienced senior manager. To me, she’s a force multiplier.
