Isero is a leading B2B ironmongery and hardware distributors (e.g. tools, fasteners, door and window fittings) with 38 branches in the Netherlands. Isero differentiates itself through its high service offering and product expertise. H2 partnered with the founding family to professionalise the business and thereafter consolidate the sector. Isero more than doubled in size through the opening of six new branches and via six add-on acquisitions. Isero was sold to Grafton Plc (UK).
