FREE TRAININGS

 Hi, I am Sietske

 founder of The House of NIA — a six-figure in sales brand evolving into a seven-figure in sales creative empire.


From building international communities like the The House of NIA ecosystem to leading 275+ online festival, creating 15k masterminds, and developing my own coaching certification worldwide, I've guided thousands into new paradigms of wealth, creativity, and power.


My work merges artistry, regenerative wealth, business, and embodied leadership — showing feminine core entrepreneurs how to craft ecosystems where a €19 “yes” naturally grows into €30K commitments.


My hyper creative brain help me to turn ideas into brand visions and my stobburnly 'I want to do it my way' makes me redifine what’s possible in high-ticket sales, planetary wealth creation & circulation, and brand artistry.
