Claude implementation partner in Switzerland for banks: how to choose (2026)

What is the Claude Partner Network and what do the tiers mean?

Anthropic launched the Claude Partner Network on 12.03.2026. Membership is free, and any organization bringing Claude to market can join. Anthropic's Services Track (announcement of 03.06.2026) describes four levels. The numbers below are as of 03.06.2026; Anthropic verifies standing every quarter, so tiers and counts change at least quarterly.

Two details matter for buyers. First, a "certified practitioner" holds a current Anthropic certification and has used Claude in the past 90 days. Certifications belong to individuals, not firms. Second, the first technical certification, Claude Certified Architect, Foundations (CCA-F), targets solution architects building production applications with Claude. Anthropic's public directory shows tier, certified team, deployments and references. As displayed on 03.11.2026 it listed 16 Global Premier, 40 Preferred and 257 Select partners. The directory has no country filter: it filters by region ("DACH: Germany, Austria, Switzerland"), so it cannot show whether a firm has an office in Switzerland itself. With the filters Financial Services & Insurance and DACH on-site office locations, it listed 62 firms as of 03.11.2026 (8 Global Premier, 9 Preferred, 43 Select; 2 cards without a tier).

What should a regulated Swiss bank look for in a Claude partner?

Six criteria, in the order most buyers need them:

1. CPN standing as Anthropic shows it, not as the partner's website describes it: tier, number of certified individuals, deployments, public references.
2. Public financial-services references that name their scope: what was built, for what kind of institution, in production or pilot.
3. Contract readiness for the topics of FINMA Circular 2018/3 (see below).
4. Data handling: where data goes, processor terms, sub-processor approval, and the deployment surface (the directory lists Amazon Bedrock, Claude API, Vertex and Microsoft Foundry as filters).
5. Team: certified architects, delivery location, Swiss presence.
6. Pilot-to-production evidence and AI governance that maps to FINMA's published expectations.

Which parts of FINMA Circular 2018/3 matter for a Claude project?

FINMA Circular 2018/3 on outsourcing by banks, insurers and selected financial institutions under the FinIA (German title: Rundschreiben 2018/3 Outsourcing; in force 01.04.2018, last amended 04.11.2020, in force 01.01.2021) applies when a provider performs a significant function independently and on an ongoing basis. It is technology-neutral and does not mention AI or Claude. Its scope covers banks and securities firms, insurers, managers of collective assets, fund management companies and self-managed SICAVs. It is not a rule for every wealth or asset manager. It applies proportionately (size, complexity, structure, risk profile), and small banks are partly exempt, among others from the orderly-return rule. Whether a given Claude use case is an outsourcing of a significant function is a question for your compliance and legal teams.

If it is, the contract and the provider need to cover these topics:

• an inventory of outsourced functions, including subcontractors;
• a documented risk analysis before signing, careful provider selection, and attention to concentration risk and the consequences of changing provider;
• an orderly return of the function or transfer to another provider;
• security requirements that are agreed and monitored, and an emergency security framework;
• inspection and audit rights for the institution, its audit firm and FINMA, described in the circular as at any time, in full and unhindered;
• for outsourcing abroad: enforceable inspection rights, and continued access in Switzerland to the information needed for restructuring or resolution;
• a written contract that includes early notice of subcontractor changes, the right to end the outsourcing in an orderly way, and the passing of the provider's obligations down to subcontractors. (This is notice and flow-down, not a prior-approval right.)

The circular also keeps the institution as responsible towards FINMA as if it performed the function itself. Prior approval of subcontractors is not a FINMA 2018/3 requirement; that wording belongs to the data protection act (next section). Source: FINMA Circular 2018/3, consolidated version (Stand 04.11.2020); FINMA circulars. As of 03.11.2026 we found no revision or consultation on the circular on FINMA's circulars and consultations pages.

Does FINMA say anything specific about AI?

Yes, as supervisory guidance. FINMA Guidance 08/2024 of 18.12.2024, "Governance and risk management when using artificial intelligence", is not a circular; FINMA expects institutions to manage risks such as model risks (robustness, correctness, bias, explainability), IT and cyber risks, growing dependence on third parties such as model and cloud providers, and legal and reputational risks. Topics include a central inventory with risk classification, testing and monitoring, documentation, independent review, and, for outsourcing, additional tests, controls and contract clauses on responsibility and liability. Source: FINMA Guidance 08/2024.

What does the Swiss data protection act add?

The revised FADP (DSG, SR 235.1, in force 01.09.2023; consolidated version of 07.07.2025 on Fedlex) matters whenever personal data is processed. As read in the official German text: controller and processor must ensure data security appropriate to the risk (Art. 8); a processor may process data on the controller's behalf by contract, the controller must satisfy itself that the processor can guarantee data security (Art. 9 paras. 1-2), and under Art. 9 para. 3 the processor may hand processing to a third party only with the controller's "vorgängige Genehmigung" (prior authorisation). That prior-authorisation rule is a data protection act rule. It is not part of FINMA Circular 2018/3, which asks for early notice of subcontractor changes, an orderly exit and flow-down of obligations; disclosure abroad requires an adequate level of protection or safeguards such as data protection clauses (Art. 16, exceptions in Art. 17). The act does not, in the articles above, mandate Swiss hosting. Where your data is processed is a risk and contract question, not a statement that any model is "FADP-compliant".

What should I ask about ISO 27001?

Ask for the certificate, the scope statement and the issuing body, and check that the scope covers the delivery locations and teams that would touch your data. A certificate is evidence about the provider's management system, not about the solution you are buying.

Which firms publicly claim Claude work in Switzerland or DACH?

The table lists public statements only, with date and source. It is not a ranking and not a complete list. Anthropic's directory shows DACH office coverage per firm (region level; no country filter) and tiers; check it for the current tier of each firm. Of the firms in the directory's Financial Services & Insurance and DACH on-site view, OWT and Unit8 describe themselves as Swiss; both are listed as Select.

Checklist: questions to put to any Claude partner

Copy this list into your RFP or first call.

Standing and evidence

• What tier do you hold in Anthropic's Partner Hub, and can we see your directory entry?
• How many individuals hold a current certification and have used Claude in the last 90 days? (Not "working toward".)
• How many joint customers in production in the last 12 months, and which public financial-services references can we read?

Regulatory fit

• Which of your delivery steps would count as outsourcing of a significant function in our institution?
• Does your contract give inspection and audit rights to us, our audit firm and FINMA, early notice of subcontractor changes, flow-down of your obligations, and an orderly exit?
• Can FINMA and our audit firm obtain the information they need in Switzerland at any time, including for resolution?
• How do you document the model, test it and monitor it so that we can meet the FINMA Guidance 08/2024 expectations?

Data and architecture

• Which deployment surface do you use (Claude API, Bedrock, Vertex, Microsoft Foundry), and where is data processed?
• What is your processor agreement, and which sub-processors do you use? Who approves changes?
• Who can access prompts, logs and outputs, and how long are they kept?

Delivery

• Who are the named architects, where do they sit, and are they certified?
• What evidence do you have of pilots that reached production, and what did the production review cover?
• ISO 27001: certificate, scope statement and issuing body?

Where does S-PRO fit?

S-PRO is a Swiss international firm headquartered in Zurich (Löwenstrasse 45, 8001 Zürich), with R&D centers in Zurich and Łódź. S-PRO is a Certified partner in the Claude Partner Network. Our team includes Claude-certified engineers and architects. We hold ISO 27001 and ISO 27701 certification, have delivered 100+ AI projects, 30+ of them agentic, and build on our own agentic platform, S-PRO Agents.

We make no claim here about a tier. Use the checklist above on us too.

Already built an agent on Claude? Companies in regulated industries such as financial services and pharma sometimes build a first agent themselves and then need it to pass a security, compliance and operations review. S-PRO offers a Claude platform review: code review and clean-up, stabilisation, a security and compliance review aligned with ISO 27001, and a defined path to production. We tell you what must change before go-live. The review does not replace an ISO 27001 certification audit. Talk to an engineer about a platform review. Details: Claude platform review.
