The 16 Best CTO Newsletters
Below are my summaries of the best CTO newsletters that made it onto my shortlist, plus others worth mentioning. My reviews offer a look at each newsletter's audience, frequency, cost, and more.
1. The CTO Club - Best for peer-led insights from active CTOs
- Audience: CTOs, software engineering directors, and technical leaders
- Size: 14,000+ members
- Frequency: Weekly

I'll be upfront: this is our newsletter, and I think it's one of the best starting points for any CTO or technical leader looking for grounded, experience-backed guidance. Each week, we pull from a curated network of active CTOs and engineering directors at fast-growing companies to bring you insights you can actually use.
Why subscribe? The CTO Club isn't a roundup of generic tech news—it's built around the real decisions and challenges that CTOs face, from scaling engineering teams to navigating AI adoption and technical strategy.
You'll get access to expert interviews, practical guides, and thought-provoking discussions shaped by people who are doing the job right now, not just writing about it.
2. The Pragmatic Engineer - Best for engineering management
- Audience: Engineering managers, CTOs, and senior software engineers
- Size: 1,000,000+ members

It's one of the few newsletters in this space written by someone who has genuinely lived the challenges it covers.
Why subscribe? Each week, Gergely goes deep on how top tech companies actually operate—from engineering org structures to compensation trends to how AI is reshaping software teams—drawing on insider knowledge you won't find in generic tech media.

3. Software Lead Weekly - Best for curated leadership reads each week
- Audience: Engineering managers, team leads, and CTOs in tech

- Cost: Free
Software Lead Weekly is a free, hand-curated newsletter by Oren Ellenbogen—an engineering leader and author of Leading Snowflakes—delivered every week to 31,000+ engineering managers, team leads, and technical executives.
It focuses squarely on the people side of software leadership: culture, management, and team dynamics.
Why subscribe? Each issue surfaces a tight selection of articles on leadership and people management that Oren has personally vetted—so you're getting a practitioner's filter, not an algorithm's. It's less about technology trends and more about becoming a better leader, which makes it a useful counterbalance to the more tech-heavy newsletters in your inbox.
4. TLDR - Best for tech news briefs
- Audience: Tech executives, software engineers, founders, and IT professionals
- Size: 8,000,000+ members
- Frequency: Daily
- Cost: Free
TLDR is a free daily newsletter founded by Dan Ni that delivers 5-minute summaries of the biggest stories in tech, startups, and programming to over 8 million readers. It's written by engineers and industry practitioners, not journalists, which keeps the coverage grounded in what the tech community actually cares about.
Why subscribe? Each weekday issue is organized into clear sections—big tech, science, programming, miscellaneous—so you can scan it in minutes and stay current without dedicating significant time to it. Beyond the flagship edition, TLDR runs 13 specialized newsletters covering AI, DevOps, infosec, product, and more, so you can tune into exactly what's relevant to your role.

It's grown to over 1 million subscribers, which tells you something about how useful engineers and architects find it.
Why subscribe? What sets ByteByteGo apart is its heavy use of diagrams and visual breakdowns to explain topics such as distributed systems, database internals, OAuth flows, and how companies like Netflix and Kubernetes architect at scale.
6. Refactoring - Best for practical CTO advice

Why subscribe? What makes LeadDev worth your attention is its suite of newsletters tailored by seniority—including DirectorPlus, which is curated monthly for Heads, Directors, VPs, and CTOs.

8. Engineering Leadership - Best for engineering leadership resources

- Cost: Free

Why subscribe? Beyond the twice-weekly articles, paid subscribers get access to 12 structured learning tracks, 29 guides and templates, and curated course deals—making it less of a newsletter and more of a self-directed leadership curriculum.

9. The Engineering Manager - Best for practical leadership tactics

Why subscribe? James writes from direct experience, covering topics like org-wide escalation frameworks, incident management, and the realities of scaling engineering organizations—content that's just as relevant to CTOs as it is to managers. The articles tend to be longer-form and narrative-driven, which makes them a good fit if you prefer depth over quick takes.
10. Leadership in Tech - Best for curated leadership insights

- Size: 29,000+ members
- Frequency: Twice a week
- Cost: Free
Leadership in Tech is a free, curated newsletter published by Bonobo Press twice a week, targeting CTOs, engineering managers, and senior engineers.
Rather than producing original content, it handpicks the best articles across the web on engineering leadership and delivers them with short summaries.
Why subscribe? If you don't have time to track down worthwhile reading on your own, this newsletter does that work for you—covering topics like hiring, communication, architecture, AI's impact on engineering, and planning.

What sets this newsletter apart is that Will writes from direct executive experience, not theory—so topics like org design, engineering strategy, and AI's impact on technical organizations feel grounded and actionable.

It pulls together the best writing on engineering leadership, culture, hiring, process, and technology from across the web.
Why subscribe? What I find valuable here is that the curation has a clear point of view—Andy selects content that speaks directly to the day-to-day realities of leading engineering teams, not just high-level strategy. You'll also get exposure to the broader CTO Craft community, including events and resources that go beyond the newsletter itself.
13. Level Up - Best for tactical leadership advice

- Frequency: Weekly

Each issue pulls together the latest thinking on leadership, technology, processes, and organizations so you don't have to go hunting for it yourself.
Why subscribe? Pat's background as both a practitioner and advisor means the curation reflects what actually matters at different levels of technical leadership—not just generic management advice.

14. High Growth Engineer - Best for engineer career development tips

- Frequency: Weekly
- Cost: Free or $120 a year
High Growth Engineer is a free weekly newsletter written by Jordan Cutler, a Staff Software Engineer at Pinterest, focused on helping software engineers grow their careers faster.
With nearly 100,000 subscribers, it's built a strong following around practical, experience-backed advice rather than theory.
Why subscribe? Each issue covers topics like promotion strategy, communication, workflow, and goal-setting—the kind of skills that separate strong individual contributors from engineers ready to step into leadership.
If you're a CTO or engineering manager, it's worth reading to stay connected to the challenges your engineers are navigating, and to surface content worth sharing with your team. It's more engineer-facing than leadership-facing, but that's exactly what makes it a useful perspective to have in your reading rotation.

- Size: 19,000+ members

Why subscribe? What sets this apart is that the content comes directly from practitioners running studies at real companies—think case studies from Dropbox, Indeed, and Priceline on measuring engineering performance.
If you're a CTO trying to make a case for developer experience investments or navigate the shift to AI-native development, this gives you the data and frameworks to do it.
