CHAINREACTION.NL

What CHAINREACTION.NL does

CHAINREACTION.NL B.V. is a Netherlands-based teambuilding event company founded in 2019 by Lennart Peeperkorn under the Peeperkorn Company umbrella. The company designs and delivers collaborative chain-reaction construction events in which divided teams of corporate participants build interconnected contraptions from rescued and recycled materials, then trigger the full chain via a single red button. The proprietary "Chainreaction" methodology — including the role taxonomy (Organisator, Communicator, Creatief, Techneut, Caretaker, Duurzaamheids Chef, Reporter), trained "CHAINMASTER" facilitators, and a transportable crate infrastructure that enables deployment across Europe — is the core product. The portfolio extends to a DISC-profiling-integrated variant (DISC Reaction, delivered with Andere Koek), an electric soapbox-kart race (E-Zeepkist), bespoke onboarding programs, smaller (Tiny) and online (Stay Home) formats, and the charity-aligned Build to Connect initiative co-organized with PROVADA and HomePlan.

The business is a private limited company (B.V.) registered at Jachtwagen 13, Zeewolde, and is bootstrapped with no disclosed external funding. Revenue is generated through one-time custom-priced event delivery, with the size of each engagement scaling from roughly 5 to 1,500 participants; pricing varies by group size, customization, location, and duration but is quote-based rather than published. Distribution is exclusively direct: founder-led sales, the website inquiry form, and inbound referrals from partner event agencies (notably D&B eventmarketing, where Peeperkorn was previously an 18-year co-owner) and partner venues (Hart van Holland in Nijkerk, De Kaap in Zoelen, and the company's own ChainLab in Zeewolde for groups under ~50). Customers are predominantly mid-market to large Dutch enterprises across banking (Rabobank), retail (Inter Gamma, JDE, DA, The Oval Office), beverages (Vrumona), agriculture (Rijk Zwaan), industrial (Alfa Laval), professional services (Baker Tilly, Sweco, Flynth), media (NLO), and education (van Hall Larenstein), with delivered events in the Netherlands, Germany, Italy, and Belgium.

The technology stack is non-digital: the "platform" is a methodology, a trained facilitator pool, and a physical inventory of pre-collected rescued materials (slats, pipes, pulleys, toys, skateboards, beams) that enables rapid deployment. There are no disclosed software products, APIs, AI/ML capabilities, apps, or patents; the company's intellectual property is operational know-how, brand recognition (Volkskrant Magazine coverage in January 2023, Eventinspiration.nl editorial), and the embedded Peeperkorn Company network. Headcount is approximately six, and the company operates with founder-centric execution.

Core offering

CHAINREACTION.NL designs, organizes, and facilitates corporate teambuilding events in which teams of participants jointly construct a giant working chain reaction from rescued and recycled materials. Events are delivered on client premises, at partner venues, or at the company's own ChainLab in Zeewolde, and scale from 5 to 1,500 participants across multiple formats (Original, Tiny, Stay Home Online, DISC Reaction, E-Zeepkist Race, Onboarding Programs, and the Build to Connect charity initiative).

Product overview

CHAINREACTION.NL offers a portfolio of teambuilding events centered on building chain reactions and constructing vehicles from recycled materials. The core product is Chainreaction Original, a large-scale collaborative event for 5 to 1,500 participants where teams build interconnected chain reactions. This is supplemented by DISC Reaction, which combines personality profiling with the chain reaction building challenge, and the E-Zeepkist Race where teams construct and race electric soapbox karts. The Onboarding Programma adapts the chain reaction methodology for corporate onboarding and training purposes, while Build to Connect is a CSR-focused variant conducted with HomePlan and PROVADA. Smaller formats (Tiny Chainreaction, Stay Home Chainreaction) serve compact groups and virtual settings. All activities emphasize sustainability through the use of rescued and recycled materials and are fully mobile across Europe, with the ChainLab in Zeewolde serving as the company's own venue for smaller groups.
