Listed in CAATSA 2018 oligarch report, Russian billionaires 2021, ACF bribetakers list. Dual Russian/Israeli citizenship.

Mamut's Lynwood Investments CY Ltd (Cyprus-registered) was the actual entity that filed the copyright infringement claim against nginx in December 2019, not Rambler directly. Rambler Internet Holding ceded rights to bring IP claims to Lynwood. This means Mamut acted through his personal Cyprus investment vehicle, not through the Rambler corporate structure, suggesting personal initiative rather than purely corporate action. Mamut became part-owner of Rambler with Potanin in 2013, bought out Potanin's stake in 2016. Sberbank acquired 46.5% of Rambler in Aug 2019, leaving Mamut's A&NN with 46.5%. The nginx raid occurred in Dec 2019, six months after F5 Networks bought NGINX Inc for $670M in March 2019.
Mamut's UK/London network hub is Alastair Tulloch of Tulloch & Co (4 Hill Street, London W1J 5NE). Tulloch has 62+ UK company appointments spanning Mamut Foundation, Lebedev Foundation, Lebedev Holdings, Khodorkovsky Foundation, Golubovich Foundation, Grishin Foundation, Digital Sky Finance LLP (Yuri Milner's DST), Odnoklassniki (Russian social network), Evening Standard (Lebedev), Raisa Gorbachev Foundation, The Journalism Foundation, and DST Global Investments. This positions Tulloch as a critical professional intermediary for multiple Russian oligarchs in London, not just Mamut.
Mamut's Cyprus directors on Hemma Retail UK: Rebecca David (Cypriot, Cyprus-resident, appointed 2018-06-06) and Margarita Maksimenkova (Russian, Cyprus-resident, appointed 2018-06-06, resigned 2022-03-09 -- same day as Lynwood-to-Hemma rename). Also Marina Groenberg (Swiss, director since 2011 on both Waterstones/Hemma Retail and Mamut Foundation). Maksimenkova's resignation coinciding with the rename date suggests she was the Mamut-connected director being removed during the distancing operation.

Mamut's systematic post-2022 rebranding: Both Lynwood Investments CY (renamed Hemma Investments CY, 2022-03-08) and Lynwood Retail UK (renamed Hemma Retail UK, 2022-03-09) were renamed within ONE DAY of each other, 12-13 days after the Ukraine invasion. Mamut Foundation was dissolved Aug 2022. This coordinated Lynwood-to-Hemma name change across Cyprus and UK entities simultaneously is a clear distancing operation as sanctions pressure intensified.
