Signal profile reconstructed from the funding graph — independent market behaviour, not media. Every round links to its source.
Coming to the profile as data accumulates: Estimated portfolio returns · Historical accuracy (early winners) · Public endorsements & mentions · News / social signal correlation — the "smart money" feedback loop needs longitudinal outcomes + the media pipeline.
Firms that shared funding rounds with Jane Street — the recurring syndicate. More shared deals = a tighter relationship (co-investment frequency).
