"What's the best long con you've ever pulled?"
Here's one.
In 2006, reddit was sold to Conde Nast. It was soon obvious to many that the sale had been premature, the site was unmanaged and under-resourced under the old-media giant who simply didn't understand it and could never realize its full potential, so the founders and their allies in Y-Combinator (where reddit had been born) hatched an audacious plan to re-extract reddit from the clutches of the 100-year-old media conglomerate.
Together with Sam Altman, they recruited a young up-and-coming technology manager with social media credentials. Alexis, who was on the interview panel for the new reddit CEO, would reject all other candidates except this one. The manager was to insist as a condition of taking the job that Conde Nast would have to give up significant ownership of the company, first to employees by justifying the need for equity to be able to hire top talent, bringing in Silicon Valley insiders to help run the company. After continuing to grow the company, he would then further dilute Conde Nast's ownership by raising money from a syndicate of Silicon Valley investors led by Sam Altman, now the President of Y-Combinator itself, who in the process would take a seat on the board.
Once this was done, he and his team would manufacture a series of otherwise-improbable leadership crises, forcing the new board to scramble to find a new CEO, allowing Altman to use his position on the board to advocate for the re-introduction of the old founders, installing them on the board and as CEO, thus returning the company to their control and relegating Conde Nast to a position as minority shareholder.
JUST KIDDING. There's no way that could happen.
