Menswear startup Thread has raised $22 million (£16.7 million) to help men navigate clothes shopping. Thread uses a mix of machine learning and real-life stylists to learn about its customers' fashion tastes, and recommend stylish clothing accordingly. The company has well-known brands such as Hugo Boss and Barbour on board, and more than 1 million customers. The company will use the money to cement itself as a household name and build up its technical capabilities.
