Our mission is to change the way people eat. Our co-founder, Will Shu, started the company in 2013 because he was frustrated with London’s slow and poor quality food delivery options. Will decided to bring technology together with the city’s best-loved restaurants to get high-quality restaurant food to customers in the quickest and most efficient way possible. We've come a long way since then by establishing ourselves as one of the UK's most exciting tech companies and expanding into 12 countries with over 1000 full time staff.
