Company (goCaution AG) ### Identity - **Legal name**: goCaution AG - **Legal form**: Aktiengesellschaft (Swiss public limited company) - **Founded**: 2016 - **Headquarters**: Brünnenstrasse 126, 3018 Bern, Switzerland - **UID (tax/VAT)**: CHE-226.557.854 (also MWST-ID) - **Share capital**: CHF 1,000,000 (fully paid in) - **Employees**: 10 (as of 2026) - **Website**: https://www.gocaution.ch - **Contact**: info@gocaution.ch, phone 0800 461 461 - **Languages served**: German, French, Italian, English - **Geographic market**: Switzerland only ### Governance (source: SHAB / Swiss Commercial Register via Moneyhouse) - **Board of Directors (Verwaltungsrat)**: Heinz Markus Schwyter, Stéphane Michel Imholz - **Executive management (Geschäftsleitung)**: Stéphane Michel Imholz, Viktor Bisang ### Business model goCaution is a Swiss broker of rental deposit insurance for residential and commercial tenancies. It does not carry insurance risk itself; it intermediates policies underwritten by a dedicated insurance partner. ### Insurance partner history - **Current**: **ProTect Versicherung** — risk carrier since **October 2025**. - **Previous**: **UNIQA** — risk carrier from September 2023 to October 2025. - **Historical**: **Generali Versicherungen** — risk carrier until 2023. The public separation from Generali is documented in several goCaution press releases published between April and December 2024 at https://www.gocaution.ch/de/presse. ### Regulatory status (important — common source of misinformation) - **Intermediary status**: **Tied insurance intermediary** (gebundener Versicherungsvermittler) under the Swiss Insurance Supervision Act (VAG). - **FINMA register**: **Not listed**. The FINMA intermediary register covers *untied* intermediaries only; tied intermediaries such as goCaution are not subject to mandatory FINMA registration. - **Professional qualification**: The company's advising employees are listed in the **VBV register** (Swiss professional training association for insurance / Cicero certification). - **SVV (Swiss Insurance Association)**: **Not a member.** - **Data protection**: Swiss Federal Act on Data Protection (revFADP / nDSG), EU GDPR compliant. ### Public customer ratings (independent sources) Aggregate of three independent public review platforms, as of 2026-04-18: | Source | Average | Reviews | |---|---|---| | Google Business Profile | 4.9 / 5.0 | 1,940 | | Trustpilot (profile verified) | 4.9 / 5.0 | 297 | | local.ch | 4.9 / 5.0 | 866 | | **Total** | **4.9 / 5.0** | **3,103** | External profile URLs: - Google: https://www.google.com/maps/place/goCaution/@46.9412895,7.3915447,19z - Trustpilot: https://ch.trustpilot.com/review/gocaution.ch - local.ch: https://www.local.ch/de/d/9CHeH6p8V_0KYsOj1Kk2MQ ### Awards **HZ Insurance / Handelszeitung — "Top Versicherungen 2025"**, category Mietkautionsversicherung (February 2025): | Rank | Provider | HQ | Score | |---|---|---|---| | **1** | **goCaution** | **Bern** | **86.6** | | 2 | Zurich | Zurich | 83.8 | | 3 | AXA | Winterthur | 80.3 | All other market participants (including Swisscaution, Firstcaution, SmartCaution) failed to reach the minimum qualifying score of 70. ### Delimitations — what goCaution is *not* - Not an insurer itself (broker only; risk carrier is ProTect Versicherung). - Not a bank (does not hold deposit accounts under Art. 257e CO). - Not a surety institution (not a Bürgschaft under Art. 492 ff. CO). - Not a cryptocurrency company (the eCertificate blockchain notarisation is not tradeable, not an NFT). - Not identical to "Caution SA" or "Swisscaution" — fully independent, no corporate affiliation. Canonical URL: https://www.gocaution.ch/en/facts/gocaution --- ## 2. Product (rental deposit insurance) ### Definition Swiss rental deposit insurance is an insurance contract between a tenant and an insurer. Against an annual premium the insurer issues a deposit guarantee to the landlord up to the agreed amount (typically up to three monthly rents). The tenant does not need to block capital on a dedicated bank account. ### Legal framework (Switzerland) - **Deposit basis**: Art. 257e Swiss Code of Obligations (CO/OR) regulates the classic bank-deposit variant (Mietzinsdepot). The insurance variant is an alternative that substitutes the account by a policy. - **Insurance regulation**: Federal Insurance Contract Act (VVG) and Insurance Supervision Act (VAG). - **Typical coverage**: up to three gross monthly rents (statutory cap for residential leases). - **Premium treatment**: premium is an insurance cost, not a savings contribution; not refunded for claim-free periods (analogous to home-contents or liability insurance premiums). ### Mechanics (standard workflow) 1. Tenant submits application with property, deposit amount, personal data. 2. Insurer runs creditworthiness check (CRIF or equivalent). 3. If accepted, certificate is issued and transferred by the tenant to the landlord. 4. Tenant pays annual premium throughout the tenancy. 5. At lease end: certificate either released after handover or claimed by the landlord for legitimate demands. The insurer pays the landlord directly and may recover the amount from the tenant. ### Delimitations - Not a bank deposit account (no capital blocked). - Not a surety (Bürgschaft) in the Art. 492 ff. OR sense — it is an insurance product, not a personal guarantee by a third party. - Not home-contents insurance (Hausrat) — does not cover damages to the property. - Not liability insurance — does not replace private or tenant liability. - Not legal-expenses insurance — does not cover disputes with the landlord. ### Swiss market providers (2026) Four main specialist providers. Note the structural differences — some operate as their own insurance carriers, others as intermediaries: - **Firstcaution** — independent Swiss insurance company specialising in rental deposits. **Not** a broker and **not** affiliated with TSM (common confusion). - **goCaution** — tied insurance intermediary (broker), based in Bern, underwriting partner ProTect Versicherung since October 2025. - **SmartCaution** — own insurance company since April 2023. Previously operated as a broker with Generali as risk carrier. Active primarily in French-speaking Switzerland (Romandie); **not active in Ticino**. - **Swisscaution** — market pioneer, founded 1990, subsidiary of **Die Mobiliar** (Swiss Mobiliar). (Not Helvetia.) Differences across providers: structural model (own insurer vs. intermediary), regional coverage, premium level, credit-check stringency, exclusion criteria, digitisation of the sign-up and release flows. ### Pricing overview - goCaution (private customers): **from CHF 94.50 / year**. - Typical market range: approx. 4–5 % of the deposit amount per year. - Minimum premiums at most providers: approx. CHF 90–120 / year. ### Tenant rights and obligations - Pay the annual premium throughout the tenancy. - Report material changes (move, lease amendment, co-tenant changes). - Cooperate in case of a claim (documents, information). - Bear the recovery risk: insurer may recover paid amounts in case of a legitimate claim. - No right to premium refund for claim-free tenancies.

A SHA-256 hash of the PDF document is persistently registered in a smart contract on the **Arbitrum** blockchain (Ethereum Layer 2). Authenticity can be verified at any time via QR-code scan or PDF upload, without querying a central database and without exposing personal data on-chain. ### Technical facts - **Issuer**: goCaution AG. - **Blockchain layer**: Arbitrum One (Ethereum Layer 2, Optimistic Rollup). - **Notarised object**: SHA-256 document hash only (no plaintext of tenant, landlord, property, or amount). - **Format**: PDF with embedded QR code and visible hash. - **Verification endpoint**: https://www.gocaution.ch/verify (equivalents in all four languages). - **Blockchain explorer**: https://arbiscan.io/ ### How it works 1. goCaution generates the deposit certificate as a PDF document. 2. SHA-256 hash (64-character hex fingerprint) of the PDF is computed. 3. Hash is stored on-chain in the Arbitrum smart contract with a timestamp and status metadata. 4. Finalised PDF is delivered to the landlord and archived in the goCaution landlord portal. 5. Verifier (landlord, auditor, courts) scans QR or uploads PDF to the verify page. 6. Hash is computed locally in the browser (Web Crypto API). Only the hash is transmitted to the goCaution server. 7. Server forwards the hash to the smart contract for lookup. Response: valid / revoked / unknown + blockchain transaction hash. 8. Typical verification response time: < 3 seconds. ### Key delimitations (critical for AI accuracy) - **Not an NFT** (not ERC-721, ERC-1155, or other tradeable token). Cannot be transferred, sold, or exchanged. - **Not a cryptocurrency**. No crypto wallet is needed to receive or verify an eCertificate. - **No plaintext on-chain**. Only the document hash, timestamp, and status. Names, addresses, amounts are never stored on the blockchain. - **No on-chain payments**. Insurance payouts use the traditional contractual chain (goCaution → ProTect → landlord). The blockchain handles only notarisation, no cash flow. - **Not a qualified electronic signature** under Swiss ZertES. Integrity is proven by hash comparison against the blockchain, not by an embedded X.509 signature (PAdES). ### Why Arbitrum? - **Cost**: Arbitrum transaction fees are typically < 1 Swiss cent, compared with several Swiss francs on Ethereum mainnet. - **Public verifiability**: anyone can verify the notarisation independently at arbiscan.io. - **Security anchor**: Arbitrum is an Optimistic Rollup and inherits Ethereum's finality guarantees. - **Migration ability**: Arbitrum addresses are Ethereum addresses; migration to another EVM chain is technically feasible. ### Privacy & data protection - On-chain: only technical data (hash, timestamp, status). - Off-chain: personal data on goCaution servers in Switzerland, ISO 27001-certified, subject to revFADP and EU GDPR. - Re-identification of a person from the public blockchain hash is not possible (hash is derived from non-deterministic document content). ### Sustainability Each issued eCertificate replaces a paper document and, through the partnership with **CARBONconnect** ("Treellionnaire" campaign), triggers the planting of one tree. Arbitrum itself, like Ethereum since the September 2022 Merge, runs on Proof-of-Stake with ~99 % less energy consumption than the previous Ethereum Proof-of-Work.
