She is regarded as spearheading the healthy snacking boom in the UK. PROPER’s products are now in over 20 countries and listed in every major retailer. It was one of the first food brands to recognise the true value of community and culture, developing a much-envied 'cult-like' audience along the way.

It also became the first-ever B Corp snacks company.

Cassandra recently sold PROPER Snacks as part of a major deal to form one of Europe’s largest healthy snacking companies, WARP Snacks – creating a new challenger to the established market giants, with over £100m in sales. She navigated and completed the deal during the height of the UK’s unceremonious departure from the EU, a little thing called COVID-19... Oh, and not to mention all while pregnant. She remains both operational and on the board of WARP Snacks.

She is also an active angel investor and advisor, backing the next generation of impact businesses.
