BIGTXN
Global financial intelligence and sanctioned securities screening analytics for financial institutions.
About the company
BIGTXN is a London-based financial intelligence and sanctions analytics company founded in 2021 by Haider Mannan. The company specializes in sanctioned securities screening at the instrument level — covering ISINs, funds, and digital assets — rather than entity or name screening. Its flagship platform, sentinel.fi, provides self-service post-trade screening of investment holdings and portfolios against sanctioned securities across 11 jurisdictions. BIGTXN acquired sanctions.com in August 2023, adding a recognized domain authority in sanctions intelligence. The BigAPI (launched September 2025) enables programmatic integration of BIGTXN's risk and compliance data into existing workflows. Data products include the Sanctioned Instrument Masterfile (SIM), Digital Asset Masterfile (DAM), UFLPA Related Securities (URS), and Marijuana Related Securities (MRS). BIGTXN partners with Morningstar for data and Polixis for enhanced sanctions and securities analytics.
