What Advisory Services Does Tristan Louis Offer on TNL.net?

TNL.net is the personal site of Tristan Louis, and its advisory offering is digital transformation consulting for corporations and governments. If you are looking for a single advisor who can speak to both technology and business leadership, the site positions him in three roles: advisor, speaker, and writer. The advisory work is the core service; the speaking and writing are presented as extensions of the same expertise.

What the advisory service covers

According to the site, Tristan Louis "advises corporations and governments on digital transformation." That is the full scope stated on the page. The site does not list packaged service tiers, pricing, engagement length, or a menu of specific deliverables, so anyone evaluating him should treat the advisory offering as a custom engagement rather than an off-the-shelf program.

The credibility behind the advisory practice comes from his operating background rather than from a consulting firm:

• Co-founder of 6 startups
• Former CIO of HSBC
• Former head of mobile and Internet for Deutsche Bank
• Current CEO of Casebook

That combination matters if your problem sits at the intersection of large-enterprise IT, financial services, and early-stage product building. A former CIO of a global bank and a repeat startup co-founder is a different profile from a career consultant, and the site leans on that distinction.

Who the site says has trusted him

TNL.net displays two trust sections: "Trusted by iconic brands" and "Published in mainstream media." The brand section carries testimonials rather than a client logo list, including quotes attributed to people at Pearson, MSG Securities, SSAB, and the EFF. The media section states he has been published by The New York Times, Forbes, Business Insider, and IEEE Spectrum.

For a buyer, the practical read is this: the site offers social proof from named individuals at recognizable organizations, but it does not publish case studies, engagement outcomes, or client results. If you need evidence of measurable transformation outcomes, you would have to ask for it directly.

Speaking and writing as adjacent services

The site lists two other ways to work with him:

• Speaker — available to keynote, moderate, or host an event, with digital transformation as the stated topic.
• Writer — a blog that the site says has run for three decades, previously as a newsletter, focused on analysis of the tech industry and its impact on society.

If your need is a conference slot or a moderated panel rather than a consulting engagement, the speaking page is the relevant entry point. If your need is ongoing analysis, the blog is free to read and is the lowest-commitment way to judge whether his thinking fits your organization.

How to decide whether to reach out

Choose the advisory route if you are a corporation or government body working on a digital transformation problem and you want an advisor with large-bank IT leadership plus startup operating experience. Choose the speaking route if you need a keynote or moderator on digital transformation. Use the blog first if you want to evaluate his analysis before committing to a conversation.

The site does not state pricing, availability, minimum engagement size, or response times. Contact details are provided on a dedicated contact page, along with LinkedIn, Mastodon, Bluesky, and an RSS feed, so the practical next step is to reach out through the contact page with your specific problem rather than expect a published rate card.
