LP interests in funds and SPVs

The real opening is that liquidity can move up one layer, from company shares to fund interests. When an SPV or fund is the single name on the cap table, the company deals with one holder, while investors can potentially buy and sell pieces of that vehicle instead of asking the issuer to approve every transfer. That turns a messy cap table problem into a fund administration and ledger problem, which is exactly where Sydecar, AngelList, and Carta are trying to build control points.

• This structure matters because private companies locked down direct share transfers after the SecondMarket era. ROFRs, issuer approvals, and shareholder count concerns make direct cap table trading slow and unpredictable. A vehicle keeps those frictions at the entity level instead of repeating them for every underlying LP.

• Sydecar is built around standardizing that vehicle layer. Its product automates entity setup, banking, compliance, tax, and ownership ledgers, and it explicitly aims to support future transfers inside SPVs. In practice, that means the tradable object becomes the LP stake in the vehicle, not the underlying startup share certificate.

• Carta and AngelList approach the same market from different starting points. Carta works from the cap table upward and wins when issuers want controlled liquidity on company terms. AngelList and Sydecar work from the vehicle layer outward, where recurring transfers, syndicates, and SPVs create inventory that can later be exchanged more flexibly among LPs.

The market is heading toward private liquidity rails that look less like one off brokered stock sales and more like standardized fund units moving on software ledgers. The company that becomes the default system for creating, administering, and transferring SPV interests will sit closest to the future transaction flow of pre IPO secondaries.
