“I want to express my sincere appreciation for the collaborative effort with Reinier in implementing the planning & monitoring tool Forward within our fundraising team. Our integration of last year’s fundraising plan and investments into the tool proved to be a game-changer. The insights gained have proven to be truly invaluable.

Reinier has proven to be a valuable partner, offering strategic planning expertise and invaluable insights into the world of fundraising. We look forward to another year of fruitful collaboration and achieving new milestones together!”

“Reinier [...] significantly helped us advance a global, complex proposition. Whether it’s numbers and analysis, creative direction, or executive-level coaching, Reinier can flex between them all and deliver the highest-quality results. Reinier also has the emotional intelligence to know when to sit back as one of the team, or lead out ahead with his vision. I trust him with every stakeholder to represent at the right level and always impress.”

“We’re still trying to convince Reinier to come and work for us, which will underline we wholeheartedly can recommend Reinier to you.”

“Reinier has been very instrumental in the analysis of our fundraising capabilities. He mapped the situation quickly, came with clear and powerful recommendations and has been a great help in rolling them out.”

“Reinier’s work at MSF has been outstanding. With a creative approach to fund-raising he and his team were responsible for sustained income growth in new and existing markets, allowing MSF to expand its medical humanitarian activities.”

“Reinier was my fundraising coach, but I guess you could also say he was my fundraising mentor, inspiration and role model as a fundraiser.

Reinier taught me everything I needed to know about data-driven fundraising, the donor experience, how to demonstrate leadership as the fundraising lead in a new market, and much more than that. Whether you are the beginning of your career, or a seasoned fundraiser, I am sure there will be lots of things that Reinier can teach you.

Reinier’s expertise on fundraising in Belgium, the Netherlands, Europe and globally is beyond compare and I would recommend any fundraiser to get in touch with Reinier and see if there’s a way you can collaborate. There are many fundraising resources out there, but Reinier is simply the best.”

“To gain a comprehensive understanding of the long-term effects of the decisions made in designing a healthy and well-founded fundraising mix, Forward is an excellent tool.

Within our team, we have adopted the tool to become more data-driven, allowing fundraisers to have better control and insight into the dynamics of underlying variables.

Thanks Reinier for your commitment to a more data minded sector!””

“Reinier is one of the few consultants in The Netherlands who can speak with authority and experience at all levels: from analysts to channel managers to team leaders and senior management; and navigate both organisational issues as well as fundraising technique and strategy. Which is exactly why we hired him. And he delivered.”

“What I liked about Reinier is that he is not an outsider. But from day 1 he is really part of the team - he connects and genuinely shares enthusiasm for the goals of the organization. And is clear and sincere about what should and needs to be done.”

“I really enjoyed working with Reinier. He is not just a great consultant; he is also a very pleasant and fun colleague. Honestly, he was the best sparring partner I’ve had in more than a decade! I would recommend him to every fundraising organisation.”

“Reinier is one of those rare individuals who knows everything there is to know about his craft fundraising. And he is willing to share it all with a contagious enthusiasm.”

“Reinier is not just highly skilled in fundraising, he is also a strong manager. In the middle of the reorganization at Oxfam Novib, he was staying calm in a very hectic environment.”
