1. The CTO Club - Best for free, actionable CTO strategies
- Audience: CTOs, engineering leaders, and senior tech executives scaling SaaS teams
- Cost: Free
- Platform: The CTO Club website and member dashboard
The CTO Club is our own community, and we built it because we know how hard it is to find practical guidance tailored specifically to technology leaders navigating real scaling challenges.
Why join? The CTO Club goes beyond general tech news—it focuses on the specific decisions CTOs face when growing engineering teams, modernizing architecture, managing security, and adopting AI. Members get unlimited access to benchmarks, frameworks, AI prompts, peer insights, operating guides, exclusive events, and roundtables.
2. CTO Craft - Best for facilitated mentoring circles
- Audience: CTOs, VPs of engineering, and senior tech leaders
- Size: 18,000+ members
- Membership Cost: £399/year, free membership available
- Platform: Slack, website, Campus 2.0, Zoom, in-person events
CTO Craft is a global community for CTOs and senior engineering leaders, offering a free Slack community of 18,000+ members alongside structured learning and mentoring options. It's one of the more well-rounded options I'd point to if you want both peer connection and guided professional development in one place.
Why join? What sets CTO Craft apart is its Mentoring Circles—small, facilitated groups where emerging CTOs meet regularly with an experienced former CTO coach, which you won't find in most peer communities. Beyond that, you get access to Campus 2.0 (an online learning hub with expert courses and assessments), in-person conferences like CTO Craft Con in Amsterdam and London, and industry research like their Engineering 2028 report on AI-augmented engineering.
3. Global CTO Forum - Best for international CTO networking
- Audience: CTOs, CIOs, architects, and senior technology executives worldwide
- Membership Cost: $180/year
- Platform: Website, member dashboard, online mentorship, virtual and in-person events
The Global CTO Forum is an independent, Swiss-headquartered organization connecting CTOs, CIOs, and architects across the globe through a formal membership structure built around professional recognition and cross-border networking. It's a strong fit if you're looking to build visibility and credibility within an international technology leadership community.
Why join? Membership gives you a certified GCF badge you can display on LinkedIn and your resume, annual nomination for the CTO award, and access to a global member directory and exclusive job opportunities. I think what makes it stand out from other CTO communities is the combination of formal recognition and international reach. You also get access to a mentorship program with experienced business and technical coaches, which adds real substance to the membership beyond the credential itself.
4. CTO Lunches - Best for local peer lunches
- Audience: CTOs and senior engineering leaders in global metro areas
- Size: 1,900+ members
- Membership Cost: $99/month, free membership available
- Platform: In-person lunches, email listserv, Slack (Plus), Zoom (Plus), website
Founded in 2014 by Miles Matthias and Kevin Owocki, CTO Lunches grew from a simple idea—gather more experienced technical leaders over lunch to share what they know—into a global network of 1,900+ CTOs and senior engineering leaders. It's free to join and open to engineering leaders worldwide, with monthly in-person lunches running in metros across the US, UK, India, and beyond.
Why join? If you're tired of online-only communities, CTO Lunches is worth your attention—the monthly local lunches give you real face time with peers in your city, and the worldwide listserv means you can tap into 1,900+ engineering leaders for advice anytime. I also appreciate that the community enforces a strict no-recruiter, no-sales policy, so the conversations stay genuinely peer-to-peer.
If you want more structure, the Plus tier adds a private Slack group, weekly standups, and curated expert connections for a tighter, higher-touch experience.
5. Rands Leadership Slack - Best for large-scale peer advice
- Audience: Past, current, and aspiring engineering leaders worldwide
- Size: 35,000+ members
- Membership Cost: Free
- Platform: Slack
Rands Leadership Slack is a free Slack community for engineering leaders at every stage, created and personally managed by Michael Lopp—a veteran tech executive who has led engineering at Apple, Slack, and Pinterest, and authored Managing Humans. With 35,000+ members and 750+ public channels, it's one of the largest engineering leadership communities available today.
Why join? The sheer breadth here is hard to match—750+ channels means you can find an active peer conversation on almost any leadership or technical challenge you're facing, from org design to vendor decisions to navigating layoffs. Every join request is reviewed manually by Lopp himself, which keeps the quality of conversation high despite the scale. To join, you'll email Rands directly with a short intro and a link to a public profile, and he typically responds within 24 hours.
6. CTO Academy - Best for structured leadership development
- Audience: Senior technology leaders and aspiring CTOs worldwide
- Size: 2,000+ members
- Membership Cost: $4,450
- Platform: Proprietary web platform, Slack, Zoom, in-person meetups
CTO Academy is a global technology leadership platform that pairs a structured Digital MBA curriculum with an active peer community for senior tech leaders across 100+ countries. It's built for CTOs, VPs of Engineering, and aspiring technical leaders who want more than just a peer forum — members get CPD-accredited certification alongside live sessions from practitioners like Gene Kim and Matthew Skelton.
Why join? What sets CTO Academy apart is that the community and the curriculum are inseparable — you get leadership workshops, live technology debates, a dedicated Slack, and 1-to-1 coaching drop-ins all in one place, rather than piecing them together yourself. There's also a CTO Shadowing program that gives you real-time exposure to how senior technical leaders operate day-to-day, which I haven't seen offered anywhere else on this list.
That said, community access is bundled with the Digital MBA, so the entry point starts at $4,450 — worth knowing upfront if you're comparing this to free or low-cost peer networks.
7. Reforge - Best for product-minded tech leaders
- Audience: Senior product, growth, and engineering leaders in tech
- Size: 1,000+ members
- Membership Cost: From $1,995
- Platform: Web platform, mobile app, live video cohorts, on-platform community
Reforge is a membership-based learning platform founded by Brian Balfour — former VP of Growth at HubSpot — built for senior tech operators who want to sharpen their product, growth, and engineering leadership skills through cohort-based courses and an on-demand content library. Contributors include operators from companies like Airbnb, Slack, Meta, and Pinterest.
Why join? If you're a CTO who wants to close gaps in your product or growth thinking — or get ahead on AI strategy — Reforge has dedicated courses on Engineering Leadership, AI Transformation, and AI Evals, taught by practitioners like Heidi Williams, former VP of Platform Engineering at Box.
You also get access to 1,400+ real-world work artifacts from top-tier tech companies, which I think is one of the more underrated parts of the membership. Just know going in that Reforge skews heavily toward product management, so it's a better fit if you want cross-functional fluency than if you're looking for a pure engineering-leader peer network.
8. Chief - Best for senior women tech executives
- Audience: Senior executive women in the U.S. with 15+ years experience
- Membership Cost: From $5,900
- Platform: Digital member platform, physical clubhouses, Zoom, in-person events
Founded in 2019 by Carolyn Childers and Lindsay Kaplan, Chief is a private membership network for senior executive women, including CTOs, CIOs, and VPs of Engineering across industries. Its vetted community represents 10,000+ companies and a large portion of the Fortune 100, making it a strong option for women seeking executive-level connections, coaching, and peer support.
Why join? Chief's Core Groups pair you with 8–10 peers at your level, facilitated by an executive coach across six sessions per year — which I think is genuinely useful for working through the leadership and board-track challenges that most tech communities don't address. Your membership also includes Wharton Executive Education courses on AI, finance, and entrepreneurship, plus access to physical clubhouses in New York, San Francisco, Chicago, Washington D.C., and Los Angeles.
Just keep in mind that Chief is cross-functional by design, so it's a better complement to a tech-specific community than a replacement for one — and given the waitlist, I'd recommend applying sooner rather than later.
9. REFACTOR Community - Best for casual founder-engineer networking
- Audience: Developers, founders, and technologists of all experience levels
- Size: 2,000+ members
- Membership Cost: Free
- Platform: Discord, website, affiliated in-person events
REFACTOR Community (formerly TechMasters) is a free Discord community for developers, engineers, and technical founders, started in 2014 by Ahmad Nassri — former CTO at TELUS Digital — and Andrew Moore out of the Toronto tech scene. With 17,000+ members worldwide, it's one of the longer-running free tech communities out there.
Why join? What sets this apart from more formal CTO networks is its strict no-promotion culture — conversations stay focused on actual problem-solving, knowledge sharing, and founder discussions rather than self-promotion. You'll find topic-organized channels covering everything from debugging to startup building, plus connections to affiliated events like Full Stack Toronto and DevTO. I'd recommend it for CTOs who want a casual, always-on tech network to complement more structured leadership communities.
10. Gartner Peer Community - Best for verified peer benchmarking
- Audience: Technology and business leaders at established organizations
- Size: 100,000+ members
- Membership Cost: Free
- Platform: Web-based digital community platform
Gartner Peer Community is a free, web-based community run by Gartner that connects over 100,000 verified technology and business leaders through peer-driven Q&As, polls, and benchmark surveys. It's built specifically to keep vendor pitching, recruiting, and self-promotion out of the conversation.
Why join? What sets this community apart is its verification system — every member is confirmed, so you're getting input from real peers, not anonymous voices or vendor reps. You can post questions to the broader community, run quick polls, and access One-Minute Insights reports that summarize benchmark survey data in a format that's actually digestible. I'd especially recommend it if you want fast, data-backed answers from other tech leaders on decisions you're wrestling with right now.
11. LeadDev - Best for engineering leadership events
- Audience: Engineering managers, directors, VPs, and CTOs worldwide
- Membership Cost: Free
- Platform: Website, Slack, newsletters, webinars, in-person conferences, local meetups
LeadDev has connected engineering leaders since 2015 through free content, a Slack community, and paid in-person conferences in London, New York, and Berlin. It's run by White October Events and built for engineering managers, directors, VPs, and CTOs.
Why join? The LDX3 conferences feature senior leaders from companies like OpenAI, GitHub, and Meta discussing org design, technical strategy, and engineering culture. I'd highlight the DirectorPlus track in particular—it's a curated stream of content calibrated specifically for directors, VPs, and CTOs. Beyond the events, you get free access to original research reports and a Slack community for year-round peer connection.
12. IEEE Computer Society - Best for standards-focused technology leaders
- Audience: Computing professionals, engineers, researchers, and technology executives worldwide
- Size: 370,000+ members
- Membership Cost: From $74
- Platform: Website, digital library, in-person conferences, local chapters, technical communities, webinars
Founded in 1946, the IEEE Computer Society is one of the world's largest and longest-running professional organizations for computing professionals, with 370,000+ members across 168 countries. It's governed by an elected Board of Governors and sits within the broader IEEE umbrella.
Why join? If you're a CTO who works close to deep tech, R&D, or emerging standards, this is where the foundational work happens—IEEE standards like Ethernet (802.3) and Wi-Fi (802.11) originated here, and members can actively participate in shaping future ones. You also get access to the Computer Society Digital Library, 182 conferences per year, and over 1,100 local chapters worldwide.
In most straightforward terms: This isn't a peer CTO forum—it's a technical professional body, so the value is in research access, credentials, and standards involvement rather than executive-level peer discussion.
13. Hampton - Best for venture-backed technical founders
- Audience: Founders and CEOs of tech-enabled startups in major cities
- Size: 1,000+ members
- Membership Cost: $15,000/year
- Platform: In-person core groups, local events, Slack, website
Hampton is an invite-only peer community for founders and CEOs of tech-enabled startups, co-founded by Sam Parr and Joe Speiser. It's built around small, city-based Core Groups of 8–10 vetted founders who meet monthly in person across 18 cities.
Why join? The Core Group format sets Hampton apart—you meet monthly with ~8 vetted founders in your city, functioning as a personal board of directors. You also get access to 100+ events per year, including private meetings with billion-dollar founders and curated retreats. One important caveat: membership requires founder or CEO status with $3M+ ARR or $3M+ raised, so this is best suited for technical co-founders rather than CTOs at other people's companies.
