The startup has now raised north of $32 million, with its latest batch of investors joining an existing cap table already packed with famous names (pop star Usher, NFL defensive lineman Ndamukong Suh), venture capital punch (Sands Capital Ventures, Motley Fool Ventures) and foodies (restaurateur Tom Colicchio, former Whole Foods co-CEO Walter Robb). Robb’s fund, Stonewall Robb Investments, co-led the round with New York-based Evolution VC Partners.
