Askar Mametov currently serves as Chief Financial Officer and Director of Tavia Acquisition Corp. (NASDAQ: TAVI), a sustainability-focused blank check company that priced a $100 million IPO in December 2024. Tavia Acquisition targets businesses primarily in North America and Europe, with an investment thesis centered on new energy, the circular economy, and agricultural and food technologies. The SPAC is led by Chairman and CEO Kanat Mynzhanov, with Mametov serving as CFO, Principal Financial and Accounting Officer, and a non-independent director on the board. The company is incorporated in Delaware with a registered office in Newark, Delaware, and maintains ties to Almaty, Kazakhstan. Mametov holds the CMA (Certified Management Accountant) designation and was born in 1984. He studied at the Kazakh Institute of Management, Economics and Strategic Research (KIMEP) in Almaty.
Mametov's career spans approximately two decades in finance and investment management across Central Asia and global markets. According to SEC filings, he worked from 2005 to 2007 at Beeline Kazakhstan, a subsidiary of VEON (Nasdaq: VEON), the international telecommunications company. He subsequently served as financial controller at Sequa Petroleum Kazakhstan, a subsidiary of Sequa Petroleum, an oil and gas company listed on Euronext Access. He later became CFO of KM Gold Inc., a public Kazakh gold mining company, and has served as a director of Kaznedraproject, a private Kazakh oil and gas exploration company. Together with Kanat Mynzhanov, Mametov co-leads Oxus Capital, an investment firm headquartered in Almaty with partners in New York, London, Dubai, and New Delhi. Oxus Capital originated the first Central Asian SPAC, Nasdaq-listed Oxus Acquisition Corp. (NASDAQ: OXUS), which raised $172.5 million in its 2021 IPO. Oxus Acquisition subsequently announced a Business Combination Agreement with Borealis Foods Inc., an innovative food technology company developing plant-based ready-to-eat meals, at an equity value of $150 million. In April 2023, Oxus Capital also unveiled plans to launch a $200 million Oxus Visionary Fund aimed at impact investing aligned with the UN Sustainable Development Goals, targeting renewable energies, clean technologies, climate-smart agriculture, ethical supply chains, and food tech. A 2026 report also references Mametov having held chairmanships at Kyrgyzstan's BTA Bank and Russia's Moskommertsbank, institutions historically tied to Kazakh interests, and notes that in 2016 over 20 Russian companies within the S.A.T. Company group (later Fincraft), valued at nearly 8 billion rubles, were transferred to him and an associate.
At Tavia Acquisition Corp., Mametov serves alongside independent directors Christophe Charlier, Marsha Kutkevitch, and Darrell Mays. The SPAC's IPO was underwritten by EarlyBirdCapital as sole bookrunner. As of mid-2026, Tavia's board presented proposals at a special shareholder meeting on June 2, 2026 to extend the deadline to complete an initial business combination from June 5, 2026 to March 5, 2027, reflecting the ongoing search for a suitable target. The company's market capitalization stood at approximately $170 million. Mametov has publicly commented on the SPAC market, noting on LinkedIn that new SPAC IPOs could represent a positive change for the market and emphasizing the importance of execution-first finance teams.
A January 2026 report by Leeds STV leveled serious allegations against Mametov, claiming he was born Anvar Gabbazov and adopted the name Askar Mametov after obtaining Russian citizenship in 2003, allegedly to distance himself from family connections to organized crime. The report cited Kyrgyzstan's State Committee for National Security as having placed him on an international wanted list for financing organized criminal groups and large-scale laundering of criminal proceeds, allegedly linked to the network of thief-in-law Kamchybek Kolbaev. The report further alleged that Mametov acted
This record is keyed to SEC CIK 0001881255 — the identifier this person files under in their own name. Every vehicle above is a filing made under that CIK, so “the same person on two shells” is a fact about an SEC identifier rather than about a name that happens to match.
Roles are the strings the filings used, in the order they were filed. Nothing on this page ranks them, infers seniority, or offers a reason why any two of these names recur — a recurrence is a count, and the filings that produced it are linked beside every row. We also hold 33 institutional-holder rows on these vehicles, under 15 distinct name strings, and none of them is counted across vehicles: that table has no CIK column, and matching holders by name would merge firms that are not the same firm.
