If booming sales, expanding offices and a parade of TV commercials hadn't put Jamie Siminoff on the radar of the home security industry, an early March incident certainly did. Four hours after the rumored collapse of a merger between a software start-up and security giant Honeywell, Siminoff took a cross-country red-eye, ready to swoop in with an offer of his own. Avoiding a drawn-out acquisition process, Siminoff in a single day hired all 75 of the beleaguered start-up's employees to work for Ring, his Santa Monica video doorbell company. Caught flat-footed, global giants that were weighing a purchase howled at Siminoff by phone. "They sat back, futzed around and let these people lose their jobs and now they want to harass" me, he said.
