1. Who we are
Stevin.AI ("Stevin", "we", "us") is a marketing intelligence platform operated by Stevin.AI B.V., registered in Breda, the Netherlands (KvK 42138941). We help marketing teams and agencies catch campaign issues earlier than regular reporting does, by continuously monitoring and interpreting paid and owned media data.
2. Applicability
These terms apply to any use of the Stevin platform, including the website stevin.ai, the client portal (app.stevin.ai), the Stevin Hub backend (hub.stevin.ai), the Stevin Desk consultant dashboard (desk.stevin.ai and crm.stevin.ai) and related APIs, Slack integrations and bots. This list is illustrative and not limiting: the terms apply to the platform as a whole, including parts added later or reachable at a different address. By using the platform you accept these terms.
3. What Stevin does (and does not)
Stevin delivers two things, and the difference determines who is responsible for what.
The platform signals and advises based on connected marketing data. There Stevin is read-only wherever possible: the platform does not change anything in your advertising accounts on its own. Where it can prepare an action, such as drafting an email, that happens only after explicit human review.
Management, if you buy that from us, means we do make changes in your accounts on your instruction: campaigns, budgets, keywords, ads and the related measurement setup. That happens within what we agreed beforehand. You remain the owner of the accounts and can withdraw our access at any time.
Advertising budget. You pay your advertising budget directly to the advertising platform, not to us, and we do not add a markup. We agree the budget and a daily cap beforehand and record it in writing; changes happen only with your approval. Costs charged by the platform remain for your account, including in cases of click fraud, a suspended account or a platform pricing change, unless those costs result from our intent or conscious recklessness.
What we do and do not promise. We make every effort to improve your results, but we do not guarantee any number of enquiries, any cost per enquiry, any revenue, any position in search results, or approval of ads by the platform. Those outcomes also depend on your market, your offer, your own follow-up, and on decisions by third parties such as Google and Meta over which we have no control.
4. Account and access
You are responsible for securing your login credentials. Stevin supports SSO via Google and magic-link login. Tokens from connected platforms (Google Ads, Meta, GA4, Search Console, etc.) are stored encrypted and used only for data sync supporting your reporting. We do not share tokens with third parties outside the described platform APIs.
5. Fees and billing
Fees and payment terms are set out in a separate service agreement per client. Absent specific arrangements: monthly invoicing in advance, payment term 14 days. All amounts stated are exclusive of VAT. Your advertising budget never appears on our invoice; you pay that directly to the advertising platform.
6. Availability and SLA
We aim for 99.5% platform availability on a monthly basis, measured across the Stevin Hub backend. Planned maintenance windows are announced at least 48 hours in advance. For extended outages the consultant receives a notification via Slack and/or email.
7. Data processing
Stevin processes personal data and marketing data from your clients only to the extent necessary to deliver the service. Details are in our privacy policy. For client engagements a Data Processing Agreement (DPA) applies between you and Stevin.AI B.V., available on request.
8. AI-generated output
Advice, signals, briefings and reports within Stevin are (co-)generated by AI models (Anthropic Claude and, to a limited extent, OpenAI). Output does not replace professional marketing judgement. Final responsibility for decisions made based on Stevin output rests with you or your consultant. Stevin makes reasonable efforts to safeguard quality and relevance (human-in-the-loop for tasks, confidence indicators, evidence strips).
9. Intellectual property
The Stevin platform, including code, design, AI prompts and data models, is owned by Stevin.AI B.V. You receive a non-exclusive, non-transferable usage licence for the duration of the subscription. Data you bring into Stevin (your client data, campaigns, briefings) remains yours.
10. Liability
Our liability for direct damages is capped at the amount you paid us in the 3 months preceding the event causing the damage, with an absolute maximum of EUR 5,000 per event. Indirect damages (lost profits, missed savings, reputational damage) are excluded. These limitations do not apply in case of intent or gross negligence.
11. Termination
You may terminate the subscription monthly, effective at the end of the running month, unless otherwise agreed. Upon termination your data remains available for export for 30 days, after which it is deleted according to our retention policy.
12. Changes
We may amend these terms. We will announce material changes at least 30 days before they take effect, by email or in-app notification. Continued use after the effective date constitutes acceptance of the new version.
13. Governing law
These terms are governed by Dutch law. Disputes will be submitted to the competent court in the Zeeland-West-Brabant district (court of Breda), unless mandatory law dictates otherwise.
