Girişim Sermayesi Yatırım Fonu (GSYF — Venture Capital Investment Fund) is the Turkish regulated investment fund structure for venture-capital activity, established under SPK (Capital Markets Board) regulations and primarily governed by the Communique on Venture Capital Investment Funds (III-52.4). The GSYF is the principal Turkish-onshore vehicle for institutional VC investment, providing a tax-advantageous, SPK-supervised framework that contrasts with offshore fund structures (Cayman, Delaware, Luxembourg) commonly used by international VCs.
GSYF structural characteristics include: SPK licensed founding GP entity (Portföy Yönetim Şirketi — portfolio management company); defined fund duration (typically 8 years with possible extensions); minimum fund size and unit-holder thresholds set by SPK rules; independent custodian (typically Takasbank or eligible custodian banks); independent auditor; and SPK reporting obligations aligned with broader collective-investment-scheme transparency standards.
The principal tax advantage: GSYF income is generally exempt from corporate tax at the fund level, and Turkish corporate investors holding GSYF participation units for at least 2 years receive favorable withholding-tax treatment on distributions (currently 0% for Turkish corporate unit holders, distinct from typical 15% dividend WHT). This treatment makes GSYFs attractive vehicles for Turkish corporate capital deployment into venture-stage investments — including for corporate VC programs of Turkish banks, conglomerates, and holding companies.
The GSYF ecosystem has grown materially since 2015, with notable funds operated by 212, Re-Pie, İş Portföy, ÜNLÜ & Co, Boğaziçi Ventures, ALJ, Tarvenn, and dozens of smaller managers. Total GSYF AUM crossed TRY 30B by 2024, with active deployment into both Turkish startup ecosystem investments and cross-border opportunities (often structured as GSYF investments into offshore master funds or via parallel-vehicle structures).
For startups receiving GSYF investment, key considerations include: SPK-driven reporting obligations imposed on portfolio companies, corporate-governance requirements that may exceed pure-private-VC norms, and structural restrictions on certain transaction types (related-party deals, founder secondaries). For Turkish corporate investors evaluating GSYF commitment versus offshore-fund participation, the tax advantage must be weighed against reduced flexibility on investment scope, structural rigidity around fund duration, and potentially-narrower deal access compared to leading international VC platforms.
