What Guerrillagardeners.nl does

Guerrilla Gardeners (Stichting Guerrilla Gardeners) is a Dutch nonprofit foundation (ANBI-status, established February 2020, building on a grassroots movement originating around 2010) that mobilizes citizens across the Netherlands to green urban public spaces through guerrilla gardening. It is headquartered at the Hof van Cartesius in Utrecht, governed by an unpaid three-person board (Linda Velzeboer, chair; Kike Olsder, treasurer; Tessel Hofstede, secretary), and operates entirely on freelance labor with no paid employees. The organization engages a community of thousands of decentralized participants through a biweekly newsletter, an interactive national map of guerrilla gardens, brigades, and the community forum 'het ecosysteem', reinforced by recurring events such as the Nationale Boomspiegelfeest and National Zaaidag on 22 April.

Its commercial product surface is a direct-to-consumer webshop anchored on handmade seed bombs (bloembommen) and indigenous, pesticide-free seed mixtures sourced exclusively from Cruydt-Hoeck, including specialized Ecobomb wild-bee mixes, Processierups Terminator mixes, and biological bloembollen for tree pits (boomspiegels). Supporting products include the Handboek Guerrilla Gardening (published with KNNV Uitgeverij, currently €10.00), DIY seed bomb kits, children's birthday packages, and campaign materials such as folders, posters, plant lists, and the Planten- en plandelbingo educational game. Services include open and corporate workshops at three Utrecht-region venues, paid lectures by founder Joëlle Baijer (from €400), and the Buurtvergroeners Bootcamp training program for Dutch municipalities. Distribution is omnichannel but domestic: a single-country webshop with NL/BE shipping, in-person workshops, corporate B2B relationship-gifts with personalization, and a media/earned-PR presence across NPO Radio 1, NRC, Facebook, Instagram, X, and LinkedIn.

Revenue is generated through four streams: (1) one-time webshop product sales at unit price points ranging from €0.50 to €39.95 with free shipping in the Netherlands from €45 and Belgium from €50; (2) professional services fees for workshops, corporate outings, and lectures (from €400 excl. VAT); (3) tax-deductible donations enabled by ANBI status and corporate contributions to the Bomenfonds (Tree Fund), a circular-economy partnership with NINOK houtwerk that sells €15 bomenbonnen tree vouchers (currently paused for new applications); and (4) customized bulk corporate gift orders for CSR, Earth Day, and employee-gift initiatives. There is no proprietary technology platform, no external investment, and no disclosed financials; the foundation runs on a hybrid of community volunteerism, freelance execution, and small-scale e-commerce.

Scale indicators4 records

Recent moves7 records

Expansion highlights6 records

Broad incumbents

• Natuurmonumenten: Largest Dutch nature conservation nonprofit, managing nature reserves and running large-scale member-supported programs. Comparable in ANBI nonprofit structure and Dutch operating geography; broader, far larger, and focused on protected area management rather than grassroots urban greening.
• Vogelbescherming Nederland: Dutch wildlife protection nonprofit with strong membership base, donation-funded revenue, and citizen-science components. Comparable ANBI nonprofit, donation-driven model and Dutch scope; focused on birds rather than urban plant biodiversity.
• Natuur & Milieu: Dutch environmental advocacy organization focused on policy, climate, and biodiversity lobbying. Comparable in cause-driven nonprofit model and Dutch geography; primarily advocacy- and policy-led rather than product- or community-event-led like Guerrilla Gardeners.
• IVN Natuureducatie: Long-established Dutch nature-education nonprofit operating nationwide with local chapters, school programs, and citizen-science projects. Comparable in mission and Dutch geography; broader and larger in scope, with formal membership infrastructure rather than a fully open movement.

Direct peers

• Incredible Edible Network: UK-originated community movement that inspires citizens to grow food in public spaces through guerrilla-gardening-style 'plant and share' actions. Highly comparable grassroots, decentralized, no-membership model and product-light, volunteer-driven engagement strategy, though focused on edible rather than ornamental native plantings.
• De Groene Buren: Dutch community network supporting neighbor-driven greening initiatives, endorsed publicly by Guerrilla Gardeners' customers. Comparable decentralized, neighborhood-activator model with overlapping Dutch citizen-segment targeting and similar absence of formal paid membership.
• Trees for All: Dutch ANBI-registered nonprofit foundation that funds tree-planting projects domestically and internationally, sells tree vouchers and gift packages, and partners with corporates for CSR. Highly comparable in mission (urban and ecosystem reforestation), ANBI donation structure, webshop-plus-donation revenue model, and Dutch operating geography.
• Nationale Boomfeestdag: Annual Dutch national tree-planting event and organizing body, traditionally held in March, that mobilizes municipalities, schools, and citizens to plant trees. Directly comparable event-driven, citizen-activation model with annual seasonal cadence and Dutch geographic focus.

Others

• NL Greenlabel: Dutch sustainability certification platform connecting green products, services, and professionals. Comparable Dutch sustainability-ecosystem positioning and ESG-corporate audience overlap, but operates as a certification/marketplace rather than a community-driven greening movement.
• Cruydt-Hoeck: Dutch native-seed nursery supplying Guerrilla Gardeners' entire seed-product portfolio. Adjacent rather than directly competing, but the natural vertical-integration threat: a supplier with full control of the indigenous, pesticide-free seed supply chain and the credibility that goes with it.
