we help you transform your business

what’s in a name?

I am neither especially clever nor especially gifted, I am only very very curious (Albert Einstein)

The name Shadow refers to two different things; the first one being a black cat named Shadow, who like all cats is extremely curious. We believe curiosity is our super power. Through curiosity we fall in love with the problem before coming up with solutions. The second thing has more to do with the literal meaning of the word ‘shadow’ – we aim to make you successful & shine whilst we are right beside you.

what do we do?

,What got you here won’t get you there! Whether you are growing rapidly as a scale-up, or having to adapt to a new reality/direction in a more established company, transformation doesn’t come easy. We help your top team to become really efficient and effective. For your organization (or part thereof) we diagnose what is holding you back from your aspired business performance and then we work with you to develop realistic and practical plans that will get you where you want to be. We love to help you implement these plans; we like being accountable for the end result because let’s be frank, the value isn’t created until things actually change. We can also develop your staff whilst doing so, so you won’t need us in the longer term. We also develop, design and facilitate Leadership Development programs and team interventions.
