Version 1.0 St. Gallen, Switzerland Fintech Payment Monitoring Operational Resilience
Banks structurally cannot see themselves from the outside. Reputational damage occurs externally, in spaces internal IT systems cannot directly observe. Internal monitoring systems have an inherent self-reference limitation:
| Time Window | Hours/Week | Share | Monitoring Status |
|---|---|---|---|
| Business hours (Mon–Fri 08–17) | 45 hours | 26.8% | ✅ Actively monitored |
| Evenings, nights, weekends, holidays | 123 hours | 73.2% | ❌ Unmonitored |
| Total | 168 hours | 100% |
Critical Implication: Payment failures during these 123 hours can go undetected until Monday morning. With SIC5 Instant Payment, TWINT and digital banking, transactions run 24/7/365.
With Koivu: Friday 23:00 – Escalation. 23:30 – Issue identified. 00:00 – Resolved.
Koivu maintains its own corporate accounts at Swiss banks and executes real micro-transactions ("penny tests") every 2 hours. These transactions traverse the complete payment path:
Koivu GmbH │ (initiate payment) ▼ Bank – Koivu Account X │ (via SIC, SEPA, SWIFT, TWINT etc.) ▼ Clearing Systems │ ▼ Bank – Koivu Account Y │ (receipt confirmation) ▼ Koivu GmbH → Alert on error (Email + Slack, <10 min)
| Setup | Description |
|---|---|
| Interbank (Setup A) | Payment between two banks (e.g. Bank A → Bank B) via clearing system |
| Intrabank (Setup B) | Account transfer within one bank (Account X → Account Y) |
| Day | Slots/Day | Transactions/Day |
|---|---|---|
| Monday–Friday (17:00–07:00) | 8 | 24 |
| Saturday–Sunday (24/7) | 12 | 36 |
| Total/Week | 64 | 192 |
| Total/Year | 3,328 | ~9,984 |
| Criterion | Manual Execution (Koivu) | Automation |
|---|---|---|
| Setup costs | CHF 0 | CHF 350k–900k |
| Time to go-live | 1 week | 12–18 months |
| 2FA handling | ✅ Like a real customer | ❌ Technically complex / FINMA risk |
| UI changes | ✅ Adaptive | ❌ Breaks |
| FINMA compliance | ✅ Compliant | ⚠️ Approval required |
| Alert quality | ✅ Verified alerts, no false positives | ⚠️ False positives, noise |
| Approach | Strengths | Gaps |
|---|---|---|
| Anonymised customer data | Realistic patterns, scalable | Test environments only; not usable in production; re-identification risk |
| Synthetic test data | Privacy-safe, scalable | Does not exist in production; no real 2FA; external partners (TWINT, SIX) don't know these customers; unsuitable for production debugging |
| Koivu Beta Client | Real company, real production accounts, real banking relationships, banking secrecy waiver | – |
| Use Case | Description |
|---|---|
| 🔧 Troubleshooting | Debug production issues with real transaction data |
| 📄 Documentation | Create user guides and manuals with real screenshots |

| Time | Activity |
|---|---|
| 00–05 min | Preparation: open log/Excel, generate test ID, prepare devices |
| 05–15 min | Transaction 1: eBanking transfer (CHF 0.30) |
| 15–25 min | Transaction 2: TWINT P2P (CHF 0.20) |
| 25–35 min | Transaction 3: Instant payment (CHF 0.50) |
| 35–40 min | Close: slot summary, escalation on errors, logout |
Each transaction is recorded with: ID | Date | CET time | Send time | Sender | Recipient | Amount | Reference | TXN-REF | Receipt-REF | Receipt time | Latency | Status | Error reason | Escalated?
Total escalation time: <10 minutes
For a bank with a state guarantee, a payment failure is not merely a technical issue but a governance question: reputational damage affects not only the bank but also its public guarantor (canton, confederation). Koivu provides external proof of operational resilience per FINMA and DORA, protecting both the bank and its guarantors from media escalation.
The period from Christmas to New Year involves many public holidays and reduced staffing, while transaction volumes increase (gifts, travel, rent payments). Koivu covers exactly this critical gap.
At modern banks, the "real test" often takes place in production. Koivu acts as a permanent sentinel, immediately reporting end-to-end failures after every release.
FINMA auditors ask: "Can you prove that instant payments work 24/7?" With Koivu logs: "We run end-to-end tests every 2 hours – here are the logs from the last 12 months (9,984 transactions, 99.5% success rate)."
Koivu anticipates and addresses two key regulatory frameworks for operational resilience in financial services:
| Regulation | Scope | Core Requirement | Koivu Contribution |
|---|---|---|---|
| FINMA Circular 2023/1 "Operational Risks and Resilience" (in force 1.1.2024) | Swiss banks | Operational resilience; RTO <4 hours; continuous functional tests; RCSA; reporting obligations | Error detection <2 hours, escalation <10 min, complete audit trail |
| DORA (EU) 2022/2554 (in force January 2025) | EU financial entities and banks with EU nexus | ICT risk management, digital resilience testing, third-party management, incident reporting | Continuous production tests, external validation of third-party paths, structured incident documentation |
DORA (in force since January 2025) requires financial entities in the EU to continuously monitor digital operational resilience – especially for critical ICT paths. Koivu is structurally aligned with these requirements:
| Regulation | Requirement | Koivu Contribution |
|---|---|---|
| FINMA Circular 2023/1 "Operational Risks and Resilience – Banks" (in force 1.1.2024, replaces RS 2008/21) | Operational resilience; RTO <4 hours; continuous end-to-end functional tests; RCSA processes | Error detection <2 hours, escalation <10 min, complete audit trail |
| FINMA Circular 2008/7 "Outsourcing – Banks and Insurers" | Outsourcing requirements, control obligations for outsourced functions | Koivu acts as an external service provider with complete documentation and audit trail |
| FINMA documentation obligation | End-to-end tests must be demonstrable | Complete logs (timestamp, latency, status, error reason), 7-year retention |
| Swiss DSG / EU GDPR | No use of real customer data in tests | Koivu-only accounts (no customer data) + formal banking secrecy waiver for Product #2 |
| Option | Duration | Scope |
|---|---|---|
| 1-Month Pilot | 1 month | Full-service 24/7, non-binding, zero risk |
| 3-Month Pilot (Proof of Value) | 3 months | Full-service 24/7, weekly reports & check-ins, cancellable at any time |
| Annual Operation | from month 4 | Full-service, quarterly reports, annual report, benchmarking |
| Channel | Availability | Coverage |
|---|---|---|
| SIC Instant Payment (SIC5) | 24/7/365 | ✅ Phase 1 |
| TWINT (P2P & Merchant) | 24/7/365 | ✅ Phase 1 |
| eBanking & Mobile Banking | 24/7/365 | ✅ Phase 1 |
| Card payments (Debit/Credit) | 24/7/365 | ✅ Phase 1 |
| Digital Asset Trading | 24/7/365 | On request |
| SEPA / SWIFT (Interbank) | Business hours | On request |
Koivu GmbH is a Swiss fintech from St. Gallen, live in the market since November 2025. The company provides Signal as a Service for operational resilience monitoring in Swiss banks and fintechs. Koivu monitors payment paths from the customer perspective using real transactions on production banking systems – the only method to detect "silent failures" that internal IT systems structurally cannot see. Website: www.koivu.network
Koivu was founded by Ralf Zellweger, who has 15 years of experience in payments and financial services and has presented at the Swiss Payment Forum on micropayments.
St. Gallen, Switzerland. Koivu GmbH is registered in the Swiss commercial register.
Koivu offers two products that can be used independently or in combination:
Penny tests are real micro-transactions in the range of CHF 0.20–0.50 that Koivu runs through a bank's production system using its own corporate accounts, to verify actual end-to-end functionality.
Koivu GmbH makes itself available as a real, registered Swiss company with formal bank accounts and banking secrecy waiver as a test client. Bank teams can work in the production environment with real but non-sensitive corporate data – without the compliance restrictions that apply to real customer data.
No. Koivu acts as a standard corporate bank client and requires no API interfaces, no firewall approvals and no software installations. The service has a "Zero IT Footprint".
Four reasons: (1) Banking systems require 2FA (SMS, push, hardware tokens), making automation technically and regulatorily complex. (2) eBanking UIs change regularly and break automation. (3) Third parties such as TWINT and SIC offer no test APIs. (4) Human testers detect unforeseen states (e.g. "system maintenance" banners) and generate no false positives.
Within under 10 minutes of error detection (email + Slack). Error detection itself occurs every 2 hours at most (next test slot).
Yes to both. Koivu provides complete audit trails per FINMA requirements (7-year retention), active proof of end-to-end functionality and supports compliance with FINMA Circular 2023/1 "Operational Risks and Resilience – Banks" (in force 1.1.2024, RTO <4 hours). For DORA, Koivu anticipates requirements for external independent ICT tests (Art. 25), structured incident reporting (Art. 17) and third-party monitoring (Art. 28) – with zero IT integration.
Yes. Koivu is listed as an authorised corporate client at the respective bank (standard KYC process). Penny tests are like transactions from a real customer. A formal contract between Koivu and the bank documents the purpose. All transactions carry clear references ("Koivu Test #ID").
DORA (Digital Operational Resilience Act) is an EU regulation in force since January 2025, requiring financial entities to continuously monitor their digital operational resilience – particularly regarding critical ICT paths, third-party risks and incident management. Koivu anticipates DORA structurally: external end-to-end tests on production systems with Zero Knowledge / Zero Privilege directly align with DORA requirements for independent resilience testing. Koivu is especially relevant for DORA Art. 25 (ICT testing), Art. 17 (incident management) and Art. 28 (third-party risks).
DORA applies directly to financial institutions with EU licensing or EU business relationships. For purely Swiss banks, FINMA regulation applies. Koivu addresses both frameworks and proactively positions banks for DORA-equivalent regulatory developments in Switzerland.
Entry via a 1-month pilot (non-binding, free) or a 3-month pilot (Proof of Value, full-service 24/7, cancellable at any time). No software project, no IT integration, no consultant. Start within 7 days. Pricing on request at www.koivu.network.
No. Usage-based model without licences. No IT integration costs. Only ancillary cost: minor transaction fees for penny tests (borne by the bank).
Primarily Swiss retail banks and fintechs, especially those with state guarantees (cantonal banks), systemically important institutions, banks with high FINMA compliance requirements and all banks offering 24/7 services (SIC5, TWINT, mobile banking).
No. Koivu is complementary to internal IT monitoring tools. Where internal tools monitor technical integrity (Inside-Out), Koivu validates the customer experience (Outside-In). Together they create 360° assurance.
