Leansquare SA is a Belgian investment firm based in Liege, Wallonia, Belgium (French-speaking southern Belgium's industrial-heritage region), investing risk capital in start-ups of the new economy with real potential for growth. The firm was established as an initiative of Meusinvest (the regional public-investment arm of the Liege province in Wallonia) in partnership with regional public and private stakeholders, and operates as a regional-Wallonia / French-speaking-Belgium start-up accelerator and seed-fund. Leansquare provides coaching, working space, and seed / early-stage capital to Wallonia-region and broader Belgian technology start-ups. The firm's model combines accelerator-programme / incubation support with equity investment, similar to other regional European accelerators. Detailed aggregate capital deployed, fund vintages, and comprehensive portfolio-company disclosures are partially documented in mainstream Belgian / Walloon regional-economy databases for this specific URL.
