According to RBC.ru auto-translation of October 2017 article:
The actual head of the whole “factory” is, as the RBC magazine wrote, 31-year-old Mikhail Burchik, previously the owner of his own IT companies VkAp.ru and GaGaDo, the publisher of newspapers for municipal districts. Burchik himself never officially confirmed that he runs a “factory” or works at Savushkin’s office, but in conversation with the RBC magazine he said that he advises the media “as an expert in the promotion and development of Internet projects.” Burchik personally communicates with about 20-30 people, who in turn manage the staff from 10 to 100 people depending on the direction, describes the model of the source work from the “factory”.
It’s odd, because I’ve been tracking two other possible Mikhail’s, Kurkin and Bystrov, who are sometimes credited as founder/directors of the Internet Research Agency. It’s possible all three were at different points, but makes it hard to track. But makes for a bit of confusion in the research.
Adrian Chen’s 2015 NY Times piece:
The source field on Twitter showed that the tweets Zoe Foreman — and the majority of other trolls — sent about #ColumbianChemicals were posted using a tool called Masss Post, which is associated with a nonworking page on the domain Add1.ru. According to online records, Add1.ru was originally registered in January 2009 by Mikhail Burchik, whose email address remained connected to the domain until 2012. Documents leaked by Anonymous International listed a Mikhail Burchik as the executive director of the Internet Research Agency.
In early February, I called Burchik, a young tech entrepreneur in St. Petersburg, to ask him about the hoax and its connection to the Internet Research Agency. In an article for the newspaper Süddeutsche Zeitung, the German journalist Julian Hans had claimed that Burchik confirmed the authenticity of the leaked documents. But when I called Burchik, he denied working at the Internet Research Agency. “I have heard of it, but I don’t work in this organization,” he said. Burchik said he had never heard of the Masss Post app; he had no specific memory of the Add1.ru domain, he said, but he noted that he had bought and sold many domains and didn’t remember them all. Burchik suggested that perhaps a different Mikhail Burchik was the agency’s executive director. But the email address used by the Mikhail Burchik in the leak matched the address listed at that time on the website of the Mikhail Burchik I spoke with.
