Chewse, an online B2B catering service, has been served with a $1 million round of seed-stage financing. Investors in the round include 500 Startups, InnoSpring, Telegraph Hill Partners and individual investor Chris Sacca of LowerCase Capital. Chewse will use the fresh funds to expand its workforce, as well as its delivery reach beyond the restaurant community of Los Angeles.
