Thanks to its partnership with Interpulse, Stichting De Groentedeler has grown significantly over the past few years. With expert guidance from this Leiden-based technology company, we invested in a new website with an integrated donation platform. This has enabled us to reach more people, raise more funds and make a greater impact for the more than 500 households that rely on the support of Voedselbank Leiden in 2026.
The collaboration has developed into a valuable long-term partnership. As part of its commitment to corporate social responsibility, Interpulse continues to support us with advice, innovations and by keeping our digital systems up to date.
Technology that helps people move forward
Interpulse helps organisations to make the most of technology. Its services range from ICT management and cybersecurity to web development, software development, automation and AI solutions. Whatever the project, the goal remains the same: giving people more time to focus on their expertise and core responsibilities.
“A great deal of time is often lost on administrative processes, communication and repetitive tasks that can easily be automated,” says John Zee, Project Manager Web Development at Interpulse. “Today’s technological developments and AI make it much easier to create custom software and work more efficiently. Think of AI assistants, automatically processing information from emails, connecting different systems or sending personalised communications, just as we’ve implemented for De Groentedeler.”
A social responsibility
When asked why corporate social responsibility matters, John is clear.
“As a business, you have the opportunity to share your knowledge, create opportunities and give something back to the community you operate in,” he says. “We do that by supporting social organisations such as Stichting De Groentedeler, sponsoring cultural events and offering internships and graduation projects to students from nearby universities and colleges. Our ambition is to keep helping people move forward. Just like De Groentedeler does, only we do it through technology.”
According to Interpulse, socially driven projects often differ from commercial assignments. Not because the technical challenges are different, but because these projects usually leave more room for innovation, collaboration and creativity.
“During an internship, for example, students can explore new technologies or innovative ideas that we can immediately test in practice for a foundation or local initiative. We also develop software that can later be applied more broadly. What works for a cultural organisation may also benefit an entrepreneur, and vice versa. That way, everyone gains.”
By actively thinking along with organisations and investing in genuine partnerships, Interpulse builds long-term relationships based on mutual trust.
“For us, personal contact always comes first. It allows you to quickly understand new organisations and sectors and work together on the best solutions for a wide variety of challenges. Over time, you know exactly what to expect from each other, and that makes the collaboration even more valuable. We experience this with De Groentedeler as well. We understand each other quickly, and that translates into better results.”
The advise: start small
Not every company has the resources to make large financial donations. Fortunately, corporate social responsibility goes far beyond giving money.
“My advice would be to use your own expertise if you want to help an organisation or initiative,” says John. “When your social commitment grows naturally from your own knowledge, values and strengths, you create partnerships that benefit everyone involved.”
To connect with organisations that could benefit from your expertise, John recommends starting close to home.
“Attend local networking events or simply ask around among friends and colleagues. Chances are someone knows a foundation, association or community initiative that could use some support. Start the conversation and, over time, new opportunities will naturally come your way. Especially if you actively communicate that you’re open to corporate social responsibility partnerships through your website, newsletter and social media channels.”
Thinking you’d like to support Stichting De Groentedeler too? We’d love to hear from you and explore the possibilities together.
Moving forward
Looking to the future, Interpulse sees enormous opportunities in making smarter use of data, automation and artificial intelligence.
“Many organisations already have access to large amounts of information. The real challenge is turning that data into valuable insights,” says John. “Right now, the possibilities are virtually endless. From data analysis that helps guide strategic decisions to using technology to shape an organisation’s long-term direction. When I look at De Groentedeler, there are still countless opportunities to support its mission. Who knows, one day we might create a digital vegetable coach or a cooking coach that helps people eat healthy. Or perhaps we’ll develop a digital assistant that answers questions from donors and volunteers. I’m excited to see what we’ll create and achieve together in the years ahead.”

For many visitors, this was their first introduction to Stichting De Groentedeler. The market provided a wonderful opportunity to share who we are, what we do, and why this work matters so much to us.






Unlock new networks


Although the weeks leading up to the event had beautiful spring weather, the book market weekend was dominated by rain. A shame, as it affected the turnout compared to previous markets.
We thank all parishioners and visitors who came to the book market, supported us with their purchases, and of course the HH. Petrus and Paulus Parish for choosing Stichting De Groentedeler as their charity.
