OMTANK is an Online Rental Marketplace for high-end Fashion. OMTANK opens a new revenue stream for the fashion companies by inviting them to "run their own rental shop" . This allows them to own their stock, profit from rentals and access to customer data to decide on the optimal rental portfolio. The fashion rental market is growing exponentially and it is time for fashion houses to tap into it though an expert cloud based service like OMTANK. Together we set up a great example in the Circular Economy and work towards long term Environmental and Financial Sustainability.
