Anton Borisevich has many business partners. Like Mr. Nosov, the defendant in the case of fraud in the Moscow region. They got connected through work in a company FC "Horizon" (ФК «Горизонт»). They worked together for a short time, but managed to be friends and find useful connections. This was followed by a position in the Ministry of Finance, and then in GTLK (ГТЛК), where he was successfully hooked up as the second person in the company. Every position- which is much in the working career of Anton Borisevich- expanded the range of partners, among which the closest are considered to be Vadim Kebets and lawyer Vikhlyaev.
