Procter & Gamble Co. has quietly opened an Over-the-Rhine retail shop featuring not its own products but the wares of local entrepreneurs and innovators. Preneur opened Jan. 10 at 1333 Walnut St. in Over-the-Rhine. The shop is the brainchild of P&G's Tide brand, growing out of the MyTide product, which allows customers to go online and customize their own detergent from label to scent. Preneur is starting with 12 business owners and featuring their products for sale in the boutique space. Those include things like skincare and wellness products, leather goods, plants and even a local startup's product.
