What is Stacc Mortgage Origination?

Stacc Mortgage Origination is the cloud-native, AI-assisted origination module of Stacc Mortgage Suite. It automates the full mortgage application journey — intake, document collection, KYC/AML, affordability, collateral, and payout — with deterministic credit outcomes. Used by Nordic banks including DNB, SBAB, and Eika Gruppen, with documented automation by default and 80%+ reduction in advisor handling time on complex manual cases.

How is AI used in Stacc Mortgage Origination?

Stacc Mortgage Origination applies credit-native AI: AI-assisted journeys with deterministic credit outcomes. AI handles document extraction with attribution-first tracing (Verifiable Document AI), conversational data capture via voice or chat (Deterministic Agentic Lending), and scenario modelling against the bank's credit rules to find approval pathways for borderline cases (Route-to-Yes). The credit decision itself stays deterministic — banks can show exactly which rules produced any approval or rejection — meeting EU AI Act and DORA explainability requirements.

How does Stacc Mortgage Origination ensure security and compliance?

Stacc is ISO 27001:2022, SOC 2 Type 2, and ISO/IEC 9001:2015 certified, with EU/EEA data storage, end-to-end encryption, and comprehensive audit trails. The platform is built for native compliance with GDPR, DORA, NIS 2, and the EU AI Act — every step including AI-assisted ones is logged with full traceability of inputs, outputs, and the deterministic rules that produced the credit decision.

Does Stacc Mortgage Origination integrate with existing core banking systems?

Yes. Stacc's API-native architecture provides pre-built integrations for major Nordic and European core banking systems, KYC/AML providers, property valuation services, and payment rails. The modular design lets banks deploy Mortgage Origination independently or alongside Stacc Mortgage Underwriting and Servicing, with rapid time-to-value as a core platform principle.

Does Stacc use AI in its credit platform?

Yes. Stacc takes a credit-native AI approach: the credit decision stays deterministic, governed by explicit rules, while AI plugs in everywhere it adds value — conversational applications via voice or chat (Deterministic Agentic Lending), document intelligence with attribution-first tracing (Verifiable Document AI), and automated scenario modelling against the bank's credit rules (Route-to-Yes). Banks can plug any AI model into the decision process through self-serve, no-code interfaces.

What is credit-native AI?

Credit-native AI is Stacc's framing for AI in lending: AI assists credit decisions rather than making them autonomously. Decisions remain explicit and auditable — the bank can show exactly which rules produced any outcome. Credit logic stays independent of specific AI models, so models can be updated without rebuilding the system.

Which financial institutions use Stacc?

Stacc powers 115+ financial institutions across the Nordics and Europe, including DNB, SBAB, Eika Gruppen (50+ Norwegian local banks), Aprila Bank, Bane NOR, Alphabet Denmark, and Autolease. Stacc has 200+ employees (70% software developers), 324 MNOK revenue in 2025 with 9.4% EBITDA margin, 42% revenue CAGR since 2016, and 45% of revenue outside Norway. Gartner Sample Vendor for Credit Decision Engines (2025).

Is Stacc compliant with the EU AI Act?

Yes. Stacc's credit-native AI architecture meets EU AI Act explainability requirements: credit decisions stay deterministic, every AI-assisted step is logged, and credit logic is independent of specific AI models. Stacc is ISO 27001:2022, SOC 2 Type 2, and ISO/IEC 9001:2015 certified, with EU/EEA data storage and built-in compliance for GDPR, DORA, and NIS 2.
