IT didn’t take much for Florian Seroussi, a technology investor in Manhattan, to become suspicious of his email.His misgivings were sparked late one night last year when he opened a message from an entrepreneur who was asking him to invest in a start-up. Minutes later, Mr. Seroussi’s cellphone rang with a call from the same start-up executive.Coincidence? Not to Mr. Seroussi. “What are the odds that at 10:30 at night, a guy suddenly has a vision that I’m reading his email?” he said. “They must know something that I don’t.”
