Build products from idea to launch And Beyond

Henk has been involved in hardware startups for almost entire life, either personally or as part of a community. His knowledge and diverse interests helps him to look at the problems from a different angle. At the same time his friendly attitude ("befriend you first") makes him different from most people in his position. Henk also has an extensive network and knowledge related to hardware in Shenzhen. He might be the best person to ask anything about custom hardware in China.

Henk is one of the very few voices that I have come to trust in my endeavors to manufacture my own device. So it makes me very happy to have the option of working with him for our injection molding and Supply Chain services.

Henk has this gift to turn a good idea into something real. His selfless mindset makes TroubleMaker a family in which people help each other to achieve their goals.

Coming from academia straight to Shenzhen’s tech world, I feel lucky to have Henk’s guidance to put my ideas into practice and have access to the amazing TroubleMaker’s community of makers, engineers, designers and all sorts of geeks.

Henk also supports social projects like the Women in Python which promotes gender inclusion in tech. I think everyone coming to Shenzhen should live the TroubleMaker experience.

I met Henk in February 2019 when he invited me to visit TroubleMaker. He showed me around, introduced the fervent community, and projected a vision at the same time ambitious and reachable. I joined right away. Charisma and pragmatism combine in Henk, giving him an exceptional capability to motivate and drive results.
I work with him for over two years that have seen the pandemic and the closing of the borders shatter plans and jeopardise business.

Thanks to uncommon resilience, will force, and fast adaptability TroubleMaker has crossed unscathed unchartered waters, emerging transformed and ready for the next challenge. Self discipline, intelligence, and will to learn drive Henk in his unstoppable quest for new challenges and higher achievement. Keen to seek help and accept it, he knows how to overcome his own limits. I see Henk leading and motivating a team of talented specialists in demanding technical and commercial challenges.

In the hustle and bustle cut-throat, high-tech, high-speed business scene of Shenzhen, Henk has built an oasis in the storm. TroubleMaker has created an incredible environment and culture that nurtures collaboration and mutually beneficial projects. Having had the opportunity to interview him about his China Dream story, he stands out as one of the few entrepreneurs in China who runs his business according to his values and truly gives with all his heart. I have more respect for what he is doing at TroubleMaker than any other business I have encountered in China. If you get the chance to work with Henk, leap at it!

The coach express live was amazing, very good to gain clarity on crowdfunding, shipping and email marketing, all the tools to lead to our goals. TroubleMaker has years of experience. The quality and precision of Dutch Engineers, combined with the affordability and efficiency of Chinese.

TroubleMaker is located at the heart of the biggest electronic hardware center of the world. You can get the components for fast prototyping within minutes. Henk is definitely one of the most helpful people in the hardware world in Shenzhen. If you are working on hardware product development, you should definitely get in contact with Henk!

Together with start-ups from Berlin, we visited TroubleMaker. Henk explained to us everything we needed to know to enter China. When there is one foreigner who understands the Shenzhen tech ecosystem in its full dimension, then it is Henk. He is a mastermind!

TroubleMaker is the place to be if you're a hacker, maker, engineer or simply someone that wants to get into the tech scene in the tech capital of the world… Shenzhen. The community and startups occupying the labs there are an amazing group of people that are always willing to help! Whether it be advice, networks, technical resources or just good company, TroubleMaker will sort you out :)

In Shenzhen's jungle of tech startups, co-working spaces and incubators, Henk's TroubleMaker stands out as a truly organic community of tech fans, makers and engineers in the heart of the world's largest electronics market.

Henk is really good at helping StartUp especially that need hardware integration.

Michael Eagleton

Henk is an awesome talent, so very willing to share his vast experience and knowledge with others. Making it happen and making things real is what Henk does best. Totally focused on delivering tangible value. When it comes to electronics, hardware and making your product idea a reality Henk is the person to go to. The Shenzhen Maker space "TroubleMaker" is where you'll find Henk and his team. Henk is an exceptional mentor, communicator and a multi-talented professional. It is my privilege to have collaborated together with Henk, and I do hope to find more opportunities & projects we can work together on in the near future. Highly Recommend having Henk on a team.

Brian Hooke

Meeting Henk put our startup on the right path. He connected us with everyone we needed to know in Shenzhen to bring our product to life. Highly recommend reaching out to him & his team if you're in Shenzhen.

Nick Dimitrijevic

I've been working with Henk on a few projects. He and his team at TroubleMaker can help hardware startups in Shenzhen with resources. Highly recommended for cooperation!

Yesterday I attended Coach Express and took some entrepreneur friends with me physically to the TroubleMaker venue. We sat behind Henk and George and listened passionately. As a result, we did not have further questions, for the time being. Both kindly connected with all my friends. So, if we have questions about Kickstarter in the future, related to this Coach Express session, or if we want to open a new topic for new business with TroubleMaker and the ecosystem that it supports, then we're glad we can do that! It was a very enjoyable and informative time. TroubleMaker seems one of the best, if not the best, positioned to efficiently coach on ICT-related business!

This team is great! It is great to know there exists a group of people like TroubleMaker that can help develop products. I follow the workshop and my favorite thing is that the videos are not long at all, but so full of real stuff and the possibility to read the assignment results from participants from all over the world. To my friends I'm saying that it is important to know all the possibilities early on, and enter into a social community to let grow your own network and possibilities. Great!
