Terms.
The simple version: be fair, be kind, and we will do the same. The details are below.
Last updated: 20 October 2026
These terms cover your use of the duo&co website and the services described on it. By using the site or booking, buying or signing up to anything from us, you agree to them. If you do not agree, please do not use the site.
Who we are
duo&co is run by Swann Vichot and Roxane Vichot through two companies:
- RMJV Consulting OÜ, a company registered in Estonia (registry code 16921104, VAT number EE102707353, registered address Sepapaja tn 6, Lasnamäe linnaosa, 15551 Tallinn, Harju maakond, Estonia).
- Swann Vichot EURL, a company registered in France (SIREN 831 329 941, SIRET 831 329 941 00023, VAT number FR40 831 329 941, registered address 231 rue Saint-Honoré, 75001 Paris, France). Your proposal and invoice say which of the two you are working with. In these terms, "we" and "us" mean that company. For the free things below, "we" means both.
The audit
The audit is a standalone paid service. Before we start, we confirm scope, price and timing with you in writing. We take on a limited number of audits and may decline a request if it is not a good fit, and we will say so honestly.
- Fees are as agreed in your written proposal. We invoice half before we start and half when the audit is complete.
- You give us access to the information and tools we need. You are responsible for having the right to share them with us.
- The audit gives you recommendations. What you do with them is your call.
Co.
Co. is our ongoing service, delivered by Colette, Cosmo and Cleo with a person from our team signing off. It is offered separately from the audit and only if it fits. Scope, price and term are set out in a separate agreement before anything starts.
- You approve every idea before it is carried out.
- You stay responsible for what is published under your brand.
- Co. is invoiced upfront, as set out in your agreement.
- Either side can end the arrangement with 30 days' written notice.
Free things: the podcast, the Cmd+K Club, events and Buddy
These are free to join and we may change, pause or end them at any time. Be kind to other members. We can remove anyone who is abusive, spammy or breaks the rules shared with each group. Buddy matches are made by hand, with no guarantee of a match and no obligation on either side to continue.
Our work and your content
- You keep ownership of your brand, data and content.
- Once an invoice for work is paid, you own the final deliverables made for you. We keep our methods, templates and know-how.
- We may mention that we worked with you only with your permission.
Acceptable use
Do not misuse the site: no scraping, no attempts to break or overload it, no unlawful or misleading use.
Liability
We do our work with care but cannot promise specific marketing results, as these depend on many things outside our control. To the extent the law allows, our total liability is limited to the fees you paid us for the service in question in the 12 months before the claim. Nothing in these terms limits liability that cannot be limited by law.
Governing law
Your agreement is governed by the law of the country of the company you are working with: Estonian law for RMJV Consulting OÜ, with disputes going to the courts of Tallinn; French law for Swann Vichot EURL, with disputes going to the courts of Paris. Mandatory consumer rules still apply where they give you other rights.
Changes and contact
We may update these terms and will change the date above when we do. Questions? Write to hello@duoand.co.
