Terms of use.

The basic ground rules for using duo.ca. Client engagements are governed by a separate written agreement, not these terms.

Last updated: 2026-04-21

These terms govern your use of duo.ca. By using the site you agree to them. If you do not agree, do not use the site. If you engage DUO for services, the relationship is governed by the written agreement we sign with you, not by this page.

Who you are dealing with

“DUO”, “we”, and “us” refers to Justin DeMarchi, a sole proprietor based in Toronto, Ontario, Canada, operating the business DUO. You can reach us at justin@duo.ca.

What the site is

duo.ca is the marketing site for DUO. It describes the services we offer, publishes writing on founder storytelling and go-to-market, and provides ways to get in touch. There are no user accounts, no logins, no paid features on the site itself. If you engage us for services, that happens through direct conversation and a signed agreement, not through the site.

How you can use the site

You may read the site, share links to it, and reference or quote short passages with attribution. You may not scrape the site at scale, republish full articles elsewhere, remove copyright or authorship notices, or use the content to train a commercial AI model without written permission.

If you want to republish an article or use content in a way that goes beyond normal reading and reference, email justin@duo.ca. Most reasonable requests are granted.

Intellectual property

All original content on duo.ca, including written articles, page copy, images of Justin, the DUO wordmark, and the visual design of the site, is owned by DUO or licensed to us. You do not receive any license to that content simply by visiting the site, beyond what is described in the section above.

Third-party content, logos, and trademarks (for example, client logos displayed as social proof) remain the property of their respective owners and appear with permission or under fair use.

Links to other sites

The site links to third-party sites. We do not control them and are not responsible for their content, terms, or privacy practices. Following a link is at your own risk.

No professional advice

The writing published on duo.ca reflects our views on marketing, positioning, and founder communications. It is not legal, financial, or other professional advice. Acting on what you read is your call. If a piece of advice matters to your business, get it reviewed by someone whose job it is to advise you.

Disclaimer

The site is provided on an as-is and as-available basis. We do not warrant that it will be error-free, uninterrupted, or that its content is accurate or current at every moment. To the extent permitted by law, we disclaim implied warranties of merchantability, fitness for a particular purpose, and non-infringement with respect to the site itself.

Limitation of liability

To the extent permitted by law, DUO is not liable for indirect, incidental, consequential, or punitive damages arising from your use of the site. Our total liability to you in connection with the site is limited to one hundred Canadian dollars (CAD $100). This limitation does not affect liability that cannot be excluded under applicable law, including in cases of gross negligence or willful misconduct.

This section addresses the site only. Liability under any client services agreement is governed by that agreement.

Governing law

These terms are governed by the laws of the Province of Ontario and the federal laws of Canada applicable therein. The courts of Ontario have exclusive jurisdiction over any dispute arising from these terms or from your use of the site, except where applicable law requires otherwise.

Changes to these terms

We may update these terms from time to time. When we do, we will change the date at the top of the page. Continued use of the site after an update means you accept the revised terms. If a change is material, we will make that clear.
