OTB Manifesto

01. Where others see $$$, we see people making a difference

It starts and ends with people, nothing else matters, that’s what makes or breaks businesses. Best people attract other best people and together we distort the reality to build iconic companies.

02. Where others confine, we look Outside The Box

Incremental changes are good for corporations, we seek paradigm shift - entrepreneurs with truly game changing ideas and ability to execute them. No dream is too big if appropriate people stand behind it (see point 1))

03. Where others doubt, we encourage

Building something legendary takes courage, passion, resilience and a lot of self-belief, where the world tries to bring you down. We are there for You, during ups and downs. We stick together, we win together.

04. Where others see the horizon, we see beyond

Long-term is difficult, it’s not tangible, it’s mostly blurry and hectic. No fundamental market shift happened over-night and we are fully aware of that. As Bill Gates said: “Most people overestimate what they can do in one year and underestimate what they can do in ten years

05. Where others scratch the surface, we look deep(tech)

We do not shy away from complexity, we embrace it. We challenge each other on a definition of Deep Tech, but we can’t find a mutual one, so we coined a new term: Real Tech. Real Tech cannot be defined precisely, but when you see it, you know it’s real. And with Real Tech comes real value and real change. Real Tech is sophisticated, it is multi-facet, it is paradigm-shifting, it is overwhelmingly beneficial.

06. Where others green wash, we green-light

No nonsense, no BS, no acting. Only honesty, truth and facts.
