When Jan Sramek walked into the American Legion post in Rio Vista, Calif., for a town-hall meeting last month, everyone in the room knew that he was really just there to get yelled at.
For six years a mysterious company called Flannery Associates, which Mr. Sramek controlled, had upended the town of 10,000 by spending hundreds of millions of dollars trying to buy every farm in the area. Flannery made multimillionaires out of some owners and sparked feuds among others. It sued a group of holdouts who had refused its above-market offers, on the grounds that they were colluding for more.
The company was Rio Vista’s main source of gossip, yet until a few weeks before the meeting no one in the room had heard of Mr. Sramek or knew what Flannery was up to. Residents worried it could be a front for foreign spies looking to surveil a nearby Air Force base. One theory held the company was acquiring land for a new Disneyland.
Now the truth was standing in front of them. And somehow it was weirder than the rumors.
The truth was that Mr. Sramek wanted to build a city from the ground up, in an agricultural region whose defining feature was how little it had changed. The idea would have been treated as a joke if it weren’t backed by a group of Silicon Valley billionaires who included Michael Moritz, the venture capitalist; Reid Hoffman, the investor and co-founder of LinkedIn; and Laurene Powell Jobs, the founder of the Emerson Collective and the widow of the Apple co-founder Steve Jobs. They and others from the technology world had spent some $900 million on farmland in a demonstration of their dead seriousness about Mr. Sramek’s vision.
