Dean started his corporate career in investment banking at Barclays Capital in London. He worked directly under the Fixed Income Director in the Marketing and Investor relations department, where his duties were to help private and institutional investors make informed decisions on whether to invest in the bank's structured products.
 
Dean has been involved in Startups in Recruitment and Marketing, turning the former from a distressed company into a seven-figure business within three years using his marketing, and acquisition knowledge.
 
After a management buyout, he worked with a Global Private Equity firm in the mid-market division creating greater value for stakeholders using the “buy-and-build” consolidation of companies between $10M-$75M EBITDA.
 
In 2022, Dean set up Millicent Investors to help those owners wanting an exit but who are falling short of the interest in Private Equity.
