Hello! This is Janneke, the driving force behind dim-sum. My purpose is to facilitate personal growth and better ways of working.

I’d like to introduce to you the Sum Collective, that I brought together to work together. We are a diverse, heartfelt group of independent thinkers and doers, who never settle for mediocrity. Who rather work with people than for people. 

We all share a focus on what matters most in our work: emotional and creative intelligence. A shared belief that this focus makes for more sustainable solutions brought us together. 

For every question – from people, brands, companies – we put together the smallest team possible, that can find the best solution simply, transparently and quickly.

We co-design sustainable change, gain insights and provide you with the strategic narrative to make them work for you. Also when we are not there.

— Janneke Grootings

—  Stef Spijkermans

Simply capturing what unfolds is an art, especially if you also connect with people while doing so. Combined with tying together the nonobvious and voilà: you will get insights à la Stef. Valuable insights, with which the feeling, story, and culture behind brands can come to life, in order to reach people. Because a brand is nothing to Stef, just air: helping people is what matters to him. 

Themes: human research, brand strategy, brand culture, photography

Worked with ao: Fenty, Nike, Protein, Flamingo, This Memento
