Until 2017, Sommerville was managing partner at Flamingo, where she had spent 18 years. Most recently, she has been working as a freelance research consultant and copywriter.

McGregor said: “Anniki’s skill as a qualitative researcher is matched by her enthusiasm and curiosity for humans. Having worked with Anniki for many years, I can testify to her talents and expect great things from her as part of our team at Walnut Unlimited.”
