Desktop research - meal kit delivery services in US and Europe

Meal Kit delivery services deliver to consumers everything needed for them to make a meal at home: ingredients and the recipe. Examples are Hellofresh and Blue Apron in the US and Gousto in the UK. I need desktop research about the market and the consumer. Market data includes segment size, growth, key companies, history, investment in start-ups, etc. Consumer data includes data regarding the drivers of growth: convenience, the desire to try new recipes, the need to eat more healthy food, the need to be able to control what I eat (is it healthy, is it organic, is it local, etc). This should include US and key European countries.
