Dual-source valuation that caught discrepancies 48 hours earlier

A late valuation mismatch can halt a multi-trillion compression cycle. An independent second source removed that single point of failure and moved failure upstream, while it was still cheap to fix.

Reading the schematic interfaceAn independent valuation beside internal marks before the live window, rows outside the tolerance band failing early, then locking only when both sources agree, 48 hours ahead of the live cycle.

What was broken

Institution-scale compression cycles depended on consistent valuation across sources. A discrepancy found late could halt a live cycle and force an expensive resubmission.

Product decision

Create an independent valuation view and compare two sources before the live window. Move failure upstream, while it is still cheap.

In plain terms

  • Compression cycles only run if valuations agree. A late mismatch stops the room
  • $XT+ is the notional size of cycles under this check, not revenue or assets managed
  • An independent view compared to internal marks; differences outside a tolerance band fail early
  • Success was earlier detection and fewer expensive resubmissions. This is not a pricing product

What I owned

  • Defined the product strategy: data quality as a control before live, not an ops cleanup
  • Launched the dual-source valuation and validation engine for institutional cycles
  • Tied success to detection lead time and resubmission rate across participating banks

How it works

  • Produces an independent valuation view
  • Compares results across two sources before live execution
  • Surfaces discrepancies early enough for teams to resolve them
  • Turns data quality from a late-stage failure into an explicit product control

Impact

Discrepancies surfaced 48 hours earlier. Failed-run resubmissions fell 91% across 24 banks running $XT+ cycles.
