We heard about Robust, a producer of steel fire-and-safety doors, via our own business network. We read it as an interesting opportunity in a niche market that was growing consistently, helped by tighter fire-and-safety regulations and an urbanisation trend. After investing in 2013, we devised a plan to drive Nordic consolidation and improve competitiveness in the UK. Robust introduced a new sales strategy and launched a new-generation range of steel doors. The company went on to occupy a leading position in the North European steel door market (manufacturing bespoke products) with well-invested facilities. We sold our investment in May 2019.
