The firm's name references Maiden Lane, a historic narrow street in lower Manhattan, New York City, and also evokes the Federal Reserve's ''Maiden Lane'' special-purpose vehicles (Maiden Lane I, II, III) used during the 2008 financial crisis to absorb Bear Stearns and AIG assets aEUR" reflecting a finance-industry-history-aware branding choice. Maiden Lane operates as a syndicate / fund-of-co-investments vehicle in partnership with AngelList's Spearhead program and other angel / micro-VC syndication infrastructure, enabling access to a diversified portfolio of AngelList-syndicated deals. The fund is led by Managing Partner Jonathan Horowitz and partners, with funds typically in the USD low-to-mid tens of millions range per vintage, investing modest initial cheques across a diversified portfolio of 100+ co-investments alongside lead-investor VCs.
