Sydecar Standardizes SPV Ownership
Sydecar and the new atomic unit of the private markets
The early private stock marketplaces hit a structural ceiling because they were not really software markets, they were brokerage workflows hiding behind software. Each trade still required finding a seller, finding a buyer, navigating ROFRs and company consent, and then stitching together legal and settlement steps that could take months. That worked for occasional small blocks, but it did not compound into a fast, repeatable market the way issuer run tenders or standardized SPV rails could.

Forge reduced cap table friction with forward contracts, and EquityZen used fund structures so only one vehicle sat on the cap table. But both substitutes created new frictions. forward contracts added counterparty risk at exit, and fund structures still required heavy packaging, approvals, and manual coordination.

The sell side was fragmented by design. employees often wanted to sell $50,000 to $200,000 blocks for personal liquidity, while buyers wanted bigger positions and companies wanted tight control over who showed up on the cap table. That mismatch made marketplaces dependent on brokers and high fees, not self service liquidity.

The market then shifted toward issuer controlled tenders and infrastructure players. Nasdaq Private Market became a major venue for company sponsored programs, and Carta used its cap table system of record and transfer agent role to make tender execution faster. Sydecar extends that same logic one layer up by standardizing the SPV itself.
The next phase of private market liquidity moves away from matching strangers trade by trade and toward standardized containers of ownership. As more volume flows through tenders, cap table systems, and SPV ledgers, the winning products will be the ones that turn messy bespoke transactions into repeatable infrastructure, which is exactly where Sydecar is positioned.
