    One of my customers once described me as the “grindstone of his thoughts.” This was a great compliment for me, because it reflects how I work with our customers to shape their projects by means of grants and incentives.

    The challenge for me is to make the connection between our customers’ complex projects and grant opportunities. This connection isn’t always apparent. Our talent for this ‘sport’ is an essential component of our success.

    At Plus Projects I can put my knowledge of sustainability, innovation and grants into practice. A sustainable society, that is what I want to contribute to. I hope to achieve this by showing organisations that sustainability and commercial growth can go hand in hand.

    As a Process Engineer I am familiar with the need of organisations to continuously improve their processes and make them more sustainable. Not only are these changes accompanied by major technical challenges, the financial barrier is often very high. At Plus Projects I get the opportunity to help organisations overcome the financial threshold and thus the possibility to facilitate technical progress in the field of sustainability and science.

    I have broad interest in technology, IT and finance. This makes it a lot of fun to work on innovations with many different organisations. Not only because it is interesting in terms of content, but also because I can offer the possibility of further innovation through grant funding.

    Plus Projects gives me the opportunity to explore possibilities of many different companies that contribute to a sustainable and innovative future. Lowering the financial threshold certainly helps with this. It is important to me that my work does not stop here, but that from here on, we look further together at even more sustainable development opportunities. In my view, (international) collaborations and learning from each other are central with a view to the challenges that will come our way on the way to the world of tomorrow in which purpose and profit can be combined.

About Plus Projects

Plus Projects was founded in 2005 by Marjolein Nijhuis en David Paul Doornbos with the intention not to be the biggest, but to be the best grant and incentives consultancy.

We have evolved into a successful consultancy specialised in innovation and sustainability projects that positively impact the world around us. A consultancy that aspires to build constructive relationships with its clients, and with grant institutions, without losing sight of quality, and with the courage to stick its head out from the crowd. Getting the maximum out of every project is and will always be the formula to our success.

We are proud of all the clients we have advised over the years, and with whom we have built a constructive, personal relationship. This includes the most innovative and sustainability-oriented businesses in The Netherlands; from car manufacturers to record labels to sugar plants. They know they can count on us.

We hope to be of service to you too!

Mission + Vision

Together with our clients we are at the core of complex innovation and sustainability projects, with a positive impact on our society.

It is our mission to strengthen these projects by rendering maximum grant advice. We do this with a personal approach, critically, diligently, and professionally, regarding all the stakeholders involved. This way, we actively contribute to the positive development of the world of tomorrow.

Art Connection

We have a special connection with art. Art is subjective, speaks to the imagination, demands insight and conveys the artists’ ideas. There is common ground with the world of grants, but that is besides the point in this case. Art simply belongs to Plus Projects’ fibre. This will not elude you when you visit our office, and is explicitly woven into our visual identity.
