International Finance Corporation (IFC): IFC Investment Services Projects (World Bank Group Finances One), industry: Funds, as of October 11, 2026. IFC discloses every investment project in the World Bank Group's open data set "IFC Investment Services Projects" (Creative Commons Attribution 4.0, updated daily), with an industry, a product line, a status and the amount of its equity, loan and guarantee investment in millions of US dollars. This list keeps the 338 projects that IFC classifies in the industry "Funds", whose status is Active or Pending Disbursement, whose product line is not Loan, and that have an equity amount. The fund name is the data set's company name (the legal entity IFC invests in); IFC lists each project separately, so a fund with a second commitment appears twice. The commitment is IFC's equity investment as the data set gives it, in millions of US dollars, multiplied by one million; where a project also has a loan amount only the equity is counted. Nothing is converted or estimated: the data set is in US dollars. It has no vintage year, paid-in amount, distributions, value, multiple or IRR, so those are blank. Left out: 24 fund projects that are Completed (exited), 46 that are not yet signed or are on hold, 24 whose product line is Loan or that have no equity amount, 5 whose project name IFC prefixes with CI (co-investments in a single company), and 31 that IFC's project name prefixes with DFP or DCM or whose name says credit, debt, lending, loan, bond, infrastructure or real estate. The data set has no finer label than "Funds", so a few vehicles that are not private equity or venture funds may remain. For 22 funds the data set prints an equity amount of exactly 250 (million), the same figure for some two dozen small funds; that is not a commitment to one fund, so their commitment is left blank. The other 316 commitments add up to $10411.05 million; the data set prints no total. View source

Ireland Strategic Investment Fund: NTMA Annual Report 2025: ISIF Discretionary Investments, Unquoted Investment Funds, as of December 31, 2025. The National Treasury Management Agency lists every unquoted investment fund the Ireland Strategic Investment Fund holds at the year end with two amounts in millions of euro, a "Commitment" and a "Value" (shown here as the market value); it reports no vintage year, contributions, distributions, multiple or IRR per fund, so those are blank. Dollar amounts are converted: every amount here is the printed euro amount multiplied by 1.1736 US dollars per euro, the Federal Reserve's H.10 foreign exchange rate for 2025-12-31 (federalreserve.gov/releases/h10/hist/dat00_eu.htm), and rounded to the dollar; a commitment made in another currency is printed by the Agency in euro, so it will not convert back to exactly its original amount. The Agency does not say what kind of fund each line is. Of the 162 lines in the list (total value €3,103.88 million), 28 whose own name says property, housing, hotel or logistics, infrastructure or wind and renewable power, debt, credit or mezzanine lending, or forestry are left out, as are 3 lines whose value is withheld as commercially sensitive; the other 131 are included as funds, and some of them invest in energy, housing, land or lending rather than private equity or venture capital. The separate list of unitised funds (hedge and listed-equity funds), the direct private equity holdings, loans and quoted securities in the same report are not imported. View source

Korea Venture Investment Corp. (Foreign VC Investment Fund): Partnership Fund Status of Foreign VC Investment Fund, as of July 31, 2026. Korea Venture Investment Corp., the Korean government's fund-of-funds manager, lists on its English website every fund its Foreign VC Investment Fund has committed to, with the fund's name, its general partner, the fund's size and "KVIC's Commitment", in millions of US dollars. The commitment is shown here as printed, times one million; KVIC reports the amounts in US dollars, so nothing is converted. The fund's own size and the general partner column are not imported, and KVIC reports no vintage year, paid-in amount, distributions, value, multiple or IRR per fund, so those are blank. The page has 2 tables, all included: "Partnership Fund Status of Foreign VC Investment Fund", as of 2026-07-31, has 64 funds which add up to $521.8 million while the page prints a total of $536.9 million (the page does not explain the difference); "Partnership Fund Status of Foreign VC Investment Fund II", as of 2023-12-31, has 26 funds which add up to the printed total of $252.11 million. The as-of date here is the latest of the tables' dates. KVIC's domestic Korea Fund of Funds and its Angel Fund of Funds are not part of this list. View source
