Analysis of information sources in references of the Wikipedia article "Uber" in English language version.
As it turns out, it was them. Uber confessed in February that it had hired the security firm Ergo to investigate Mayer and his lawyers. In fact, Meyer's lawyers say Ergo's investigative report was circulating in Uber's offices and may have been in the hands of the company's general counsel, Salle Yoo, on January 20, the very day the company's lawyers were saying "it is not us."
By the end of the week, Henley was on the phone with a corporate research firm called Ergo, also known as Global Precision Research LLC, asking for help with "a sensitive, very under-the-radar investigation." After a few emails, Henley worked out the terms of the deal with an Ergo executive named Todd Egeland. It would be a "level two" investigation, the middle of the three levels of work offered by Ergo. It would be drawn from seven source interviews conducted over the course of 10 days, for which Uber would pay $19,500. As with any Ergo investigation, the confidentiality of the client was paramount, and sources were never meant to know who was paying for the research. "We do quite a bit of this work for law firms," Egeland reassured him. (Ergo did not respond to requests for comment.)
