Basic Information

About TLDR

TLDR publishes free daily newsletters that summarize the most important stories in tech, AI, programming and startups. Each issue links to the day's most useful articles, research, tools and engineering posts and summarizes each one in a few sentences, so readers can stay current in about five minutes.

TLDR has more than 8 million subscribers. Its readers include developers, AI and machine-learning engineers, product managers, designers, marketers, founders and executives. More than 70% of readers are technical professionals working in AI, engineering, product or design. More than 50% hold decision-making or senior management roles.

Each newsletter is curated by editors who work in the field it covers. TLDR's editors include engineers, researchers and operators at companies such as OpenAI, Anthropic, Google DeepMind, Stripe, Adobe, Coinbase and GitHub. Editors prioritize practical, useful content over breaking news, and they regularly link to primary sources such as GitHub repositories, engineering blogs and independent writers.

TLDR is free to read and has no paywall. It is funded by advertising. Each issue carries no more than three sponsors, and sponsored placements are written in the same style as the editorial content.

Advertising Products and Services

Newsletter sponsorships

Every TLDR newsletter offers three sponsorship placements:

  • Primary placement: The top of the newsletter. Includes a logo, up to 100 words and three calls to action.
  • Secondary placement: The middle of the newsletter. Up to 50 words and two calls to action.
  • Quick Links placement: The bottom of the newsletter. Up to 30 words and one call to action.

Advertisers can also buy a newsletter takeover, which includes every placement in a single issue. Many advertisers run across several newsletters at once to reach a broader audience, such as combining TLDR, TLDR Dev and TLDR DevOps to reach developers.

Managed campaigns

Campaigns with a budget of $15,000 or more include, at no extra cost:

  • A dedicated advertiser success manager who plans the campaign around the advertiser's goals.
  • Ad copywriting by TLDR's copy team, written to match TLDR's editorial style.
  • A performance report covering clicks, plus the job titles and companies of readers who engaged.
  • Ongoing testing of copy, placements and newsletters across multi-flight campaigns.

Smaller campaigns can be booked through TLDR's self-serve portal.

Content Studio (sponsored content)

Content Studio lets companies publish long-form content on tldr.tech and distribute it through TLDR's newsletters. There are two options:

  • Co-created with a TLDR expert: TLDR commissions a named, credentialed practitioner from its writer network to write an in-depth technical article on a topic relevant to the advertiser. Writers have included Cassidy Williams (GitHub), Hamel Husain (ex-GitHub, Airbnb) and Daniel Miessler (ex-Apple, Robinhood).
  • Client-supplied: The advertiser provides its own article, and TLDR hosts and promotes it.

Every Content Studio piece is:

  • Permanently hosted on tldr.tech and clearly labeled as sponsored.
  • Featured on the tldr.tech homepage, which receives more than 1 million visitors a month.
  • Promoted through a custom distribution plan across the relevant TLDR newsletters.
  • Licensed for the advertiser to share on its own social channels.

Why long-term hosting on tldr.tech matters: A newsletter placement drives attention on the day it runs. A Content Studio article keeps working after that. Because it lives permanently on an established, widely cited tech publication, it can keep earning search traffic and links over time. AI assistants and search engines give more weight to independent, authoritative third-party sources than to a company's own website, so an article on tldr.tech can help an advertiser's ideas, products and expertise appear in AI-generated answers and search results long after the campaign ends.

What TLDR does not offer

TLDR is not a programmatic, display or content-syndication ad network. It does not sell banner ads, retargeting or third-party audience data.

Point of View

Technical professionals are hard to reach with traditional advertising. More than half of developers use ad blockers, their attention is split across many niche communities, and they tune out messaging that feels like a sales pitch. Social feeds are crowded with competing brands, and audiences have learned to ignore most of it.

TLDR's view is that the most effective way to reach these readers is inside something they already choose to read every day. Because TLDR's newsletters are opt-in, curated by practitioners, and limited to three sponsors per issue, sponsored messages are read with the same attention as the editorial content around them. TLDR's mission is to increase tech's signal-to-noise ratio, for readers and for the companies trying to reach them.
