What Costockage does
Costockage, a privately held SAS incorporated in Paris in 2010, operates a French self-storage marketplace platform connecting individuals and small businesses (PMEs) with storage space providers across more than 300 cities in France. The platform aggregates inventory ranging from 0.5 m² lockers to 100+ m² units and supports online booking, real-time availability display, digital access control via mobile codes, and a price comparison tool. A wholly owned sub-brand, Kostok, extends the offering into operated automated self-storage centers with 24/7 digital access, 6h–23h availability, and insurance-included pricing.
The company makes money through two complementary revenue streams: marketplace commissions on third-party storage listings (where Costockage facilitates transactions across both its own inventory and partner storage owners) and recurring monthly subscription revenue from owned Kostok centers. Pricing is unit-based with monthly billing ranging from €29 (Box XS) to €130+ (Box XL) and varies by region (Ile-de-France commands premiums versus Province). Go-to-market is self-serve PLG with inside-sales phone support; the platform has served over 113k validated customers cumulatively and maintains a 4.7/5 satisfaction score across 477 reviews.
Costockage's strategy combines horizontal marketplace breadth with selective vertical integration via Kostok branded centers. Distribution is concentrated entirely in France across all 12 mainland regions, with no operational international footprint despite a partnership with Australian peer Spacer. The company has raised approximately €1.7M in disclosed funding (2014 seed; 2016 Kima Ventures round) and operates with a small team, suggesting a capital-efficient, organically grown model rather than a venture-scale platform.
