Mobile-based business-to-business (B2B) marketplace Wydr, which counts venture capital firms Stellaris Venture Partners and Bessemer Venture Partners among its investors, has shut shop. According to news portal Entrackr, Gurugram-headquartered Wydr had been scaling down operations over the past three months. It was not immediately clear what led to the shutdown. Entrackr quoted a person it did not name as saying that Wydr had been looking to raise funding. However, B2B marketplace Udaan’s massive fundraise of $225 million earlier this year coupled with its rapid expansion had made it difficult for peers to survive, the person added.
