New wave of apps focus on keeping food delivery local

New food delivery apps including Traiilo, Black and Mobile, and Chowbus are aiming to offer an alternative to large third-party delivery companies, with an emphasis on promoting local restaurants and reducing the commissions paid by eateries. “We really want to empower small restaurants that serve authentic food,” said Chowbus co-founder Linxin Wen, who has seen the company’s revenue grow by 700% in the past year.
