On June 8, 2011, Spectrum Equity Investors made a $50 million minority investment in Seamless and the company was spun out of Aramark into an independent entity.

In May 2013, Seamless announced the signing of an agreement to merge with GrubHub, creating a combined company with a higher order volume and improved regional coverage.

The merger resulted in connecting diners with approximately 25,000 restaurants for online and mobile-ordering across the United States and in London.
