About

Two entrepreneurs.
Complemented by selected
specialists.

We are a duo. You work with both of us, with no pyramid behind us, no thinned-out junior team. Complemented by selected specialists where it makes sense.

Boris Manhart

Boris Manhart

Co-Founder · Leadership Sparring · Organisation Reboot

Boris has founded and helped build several companies, including a unicorn and several scale-ups across stages and industries. These years gave him a very practical view of what really carries an organisation, and what only looks good until pressure rises.

Today, his focus is work close to decisions. As a sparring partner for founders and leadership teams who want to regain clarity, alignment and ability to act when the market, the team or their own patience gives way. His work combines practical experience, strategic thinking and a strict stance on learning and ownership: consulting that doesn't take ownership away but gives it back.

As Innosuisse Expert Coach he sees more than 30 founder teams per year in early stages. That keeps his eye sharp for where organisations stumble — and how to get back on your feet without losing face. As IMD Startup Strategist he accompanies teams through strategic decisions, and as a guest lecturer at Stanford University he shares these perspectives in education. In 2023, he was named "Digital Shaper" by Bilanz magazine.

Marc Pittner

Marc Pittner

Co-Founder · Craft & Delivery

Marc comes from the engine room. Over many years he has built platforms, workflows and teams in large organisations — and brought along the inconvenient truth that even the best strategies fail when execution doesn't hold.

His contribution in the duo is the craft: he translates what emerges from diagnosis and sparring into concrete tools, workflows and organisational forms. Pragmatic, iterative, happy to use modern tools — but never falls into the tool trap. The work has to keep running in your hands afterwards, not in his.

What our clients say

What founders and CEOs
say about working with us.

Boris has helped me see the gaps in the company through strategic planning. As a result, I have filled these gaps with great people who are amazing at what they do. Much better than myself!

Boris helped us to gain clarity on goals and strategy and how this trickles down to tasks & deliverables. Within one year, we changed for the better, and the whole team can now use Boris's tools and knowledge and run with it independently.

Sebastian Weber

From the very beginning, Boris understood us and immediately recognised where our challenges were and how he could help us most efficiently.

Martin Gadient

Boris challenged us at the right moments and repeatedly said: this isn't concrete enough yet. He helped us regain focus, and we now know where to say no.
