Chernick owns El Segundo cybersecurity firm NC4 Inc., which doesn’t disclose financials, and results for similar companies were mixed over the past year while other investments that track to a prior fortune likely benefited from the overall strong markets. Chernick started software firm Candle Corp. in 1976 out of his Marina del Rey apartment and sold the business to IBM in 2004 for $641 million.
Chernick launched a video platform for the Initial Coin Offering industry. The reclusive businessman saw his right-wing subscription video service PJTV.com fold after eight years amid monetization challenges. PJTV was an offshoot of 11-year-old PJ Media, a conservative media outlet still controlled by Chernick. He later founded NC4, a maker of situational awareness and threat-detection software used by law enforcement agencies and military. Chernick and his wife, Joyce, keep a low profile but have continued to focus their philanthropic work on conservative causes, education-focused nonprofits and pro-Israel groups.
