The basic structure
A syndication pools capital from multiple investors into a single vehicle — commonly a limited liability company or limited partnership — that holds an asset or a portfolio. Investors hold an interest in the vehicle, not direct title to the underlying asset.
The sponsor forms the vehicle, sources the asset, raises the capital, and administers the investment over its life. Investors are passive: they contribute capital and receive distributions according to the vehicle's governing documents.
Who is involved
A sponsor or general partner runs the deal. Limited partners or members provide capital. Counsel prepares the governing documents and offering materials. An accountant handles allocations and tax reporting. A fund administrator maintains capital accounts and investor records.
In a well-run vehicle these roles are distinct and their work is traceable. Where one person performs several of them, documentation discipline matters more, not less.
Where the money moves
Capital moves in at subscription or at capital call, and out at distribution. Between those events the vehicle operates the asset. The record that ties it together is the capital account: contributions in, distributions out, allocations of profit and loss, and a closing balance.
If a platform cannot show you the capital account and the calculation behind it, the reporting is a narrative rather than a record.
