Business Growth Fund, a private equity firm, completed an investment in Brisant Secure, a security system supplier. Financial terms were not disclosed. “BGF’s investment is a milestone in Brisant’s development, and it marks the start of an exciting new era for the business. We’ve reached a point where we have more ideas for innovative hardware than we could bring to market, and with BGF as an invested partner we can explore these opportunities and channels with this incredible pool of experience, knowledge and contacts. I think it’s also significant that such a prominent investor recognises the growth and potential of our sector," Nick Dutton, Brisant Secure Joint-CEO,
