Shark Tank star Robert Herjavec is among the top cybersecurity experts in the world, with an estimated net worth of £232.84 million ($300 million). He derived his wealth primarily through founding leading cybersecurity companies and selling them to top tech and private equity firms.
Herjavec's first breakthrough was in 2000 when he sold an internet security software integrator called Brak Systems to AT&T Canada for roughly £23 million ($30 million). In the past three decades, the entrepreneur has founded several other cybersecurity firms and netted millions of dollars by following a similar investment approach. On his LinkedIn profile, Herjavec claimed that his latest cybersecurity venture, which he built from scratch, generated over a billion dollars in revenue and later sold it to private equity for a handsome amount.
