Reconciliation Infrastructure for Modern Finance Operations
Settler builds the deterministic reconciliation layer that serious financial infrastructure demands. API-first, inspectable at every step, and designed for teams that require operational confidence over automated guesswork.
Manual reconciliation is a phase. Deterministic, API-based reconciliation is the stable end-state that mature financial operations evolve toward. Settler accelerates that transition.
Operating Principles
These are not aspirational values. They are structural properties of how Settler operates.
Determinism Over Heuristics
Every reconciliation produces identical results given identical inputs. No hidden logic. No probabilistic drift. Decisions are reproducible and auditable.
Governance by Default
Tenant isolation, audit trails, and policy-based access controls are structural properties of the platform, not optional features layered on afterward.
Rules as Code
Matching rules are version-controlled, testable, and deployable through standard CI/CD pipelines. Reconciliation logic receives the same rigor as application code.
Human-in-the-Loop
Settler surfaces variances and evidence for human review. It compresses uncertainty without replacing judgment. Final authority remains with operators.
The Evolution of Financial Infrastructure
