Platform Core
Deterministic Reconciliation. AI-Assisted Review.
Settler is API-first infrastructure for finance and fintech teams: a deterministic matching core, AI-assisted exception triage, tenant-safe isolation, and audit-grade evidence trails built into every run.
The Settlement Pipeline
From raw data ingestion to verifiable evidence, every stage is deterministic.
Ingest:Normalized ingestion via verified Stripe, Bank & ERP connectors
AI-Assisted Exception Review
Don't waste time on trivial variances. Our AI layer surfaces the context you need to resolve exceptions with institutional confidence.

Review Governance
Settler is built on verifiable truth. This registry connects marketing claims to concrete implementation modules, ensuring every capability is auditable.
Execution runtime modules
Adapter, SDK, and protocol packages back deterministic execution and integration boundaries.
Deterministic Engine
Rules-based matching with field-level tolerance. Same inputs and same rules always produce identical output and identical evidence hash. No hidden logic.
- Configurable matching rules in code
- Field-level variance with tolerance windows
- Multi-source joins across adapters
- Floating-point safe (integer cent arithmetic)
AI-Assisted Review
AI compresses exception triage time by surfacing context, suggesting classifications, and flagging anomalies. Humans retain final authority on every decision.
- Exception context summarization
- Anomaly pattern detection
- Suggested resolution classifications
- Review history and audit trail
Governance & Controls
Role-based access, tenant isolation, and configurable policy controls. Every decision is logged with actor, timestamp, and documented reason.
- Owner / Admin / Reviewer / Viewer roles
- Tenant-scoped API keys
- Policy-gated mismatch resolution
- Exportable compliance evidence
Replay & Provenance
Any historical run can be replayed from stored inputs and rules. The output hash must match the original. Debug mismatches or prepare for audit without re-running live systems.
- Hash-verified replay of any run
- Rule version fingerprints in evidence
- Provenance chain across sequential runs
- Determinism CI enforcement
Engineered for high-integrity financial operations where every byte counts.
