LinkedIn: Technical Depth with a Global Professional Audience

‍

‍

Guido Appenzeller uses LinkedIn as his primary platform for delivering high-impact, technically grounded content to a professional audience. His posts focus on the economics and architecture of large language models (LLMs), token cost efficiencies, and infrastructure scalability. Each post is backed by data—typically in the form of original or sourced charts, performance graphs, or annotated visuals. These insights cater directly to CTOs, AI engineers, and enterprise-focused investors.

‍

His tone on LinkedIn is analytical and informative, with a slightly opinionated but always professional delivery. Unlike creators who post frequently to stay visible, Guido prioritizes signal over noise, posting only when he has valuable insight to share. This strategy has earned him a dedicated following of over 31K users, many of whom actively engage through comments and reshares. His voice carries authority, and his consistency has built long-term trust in his insights.

‍

‍

Though he posts only around four times per month, his engagement levels remain high thanks to the depth and clarity of each piece of content. From breaking down GPU usage trends to commenting on LLM market shifts, his posts often lead to extended discussions in the comments. His posts are scheduled strategically—once a week at 3 PM, which aligns well with a global audience of engineers, researchers, and founders. It’s a deliberate approach that maximizes reach across time zones.

‍

Guido’s engagement metrics reflect his influence: a 1.64% engagement rate, an average of 510 interactions per post, and over 18.4K monthly views. These numbers are impressive, especially considering his low-frequency strategy. His content doesn’t chase virality—it delivers lasting value. For companies and professionals operating at the intersection of AI, hardware, and infrastructure, Guido’s LinkedIn is a must-follow source of trusted thought leadership.

X (Twitter): Real-Time Reactions and Personal Industry Moments

‍

‍

On X (formerly Twitter), Guido adopts a more casual and conversational tone while still keeping the content technically relevant. He uses the platform to amplify key takeaways from panels, highlight podcast episodes, and share quick reactions to industry events. His tweets range from insights about AI agents and team achievements to shorter acknowledgments of community events. The platform allows him to humanize his brand and engage in real-time discourse with the tech community.

‍

Although his audience on X is smaller—7.9K followers—his content is aligned with the platform’s real-time pace. He posts about 2.5 tweets per week, mostly scheduled for 2 PM, again hinting at a focus on international or early-rising tech users. His best-performing content includes embedded media such as video podcast clips and milestone updates from Andreessen Horowitz-backed projects. These moments highlight both his work and the broader activity of his network.

‍

‍

The engagement rate on X is relatively low at 0.06%, but context is key—Guido uses X more for community signaling and visibility than for deep engagement. His content performs best when it’s connected to recognizable brands like a16z, OpenAI, or when he’s sharing broader team wins. His reach per post still averages around 712 views, with standout tweets garnering thousands of impressions—particularly when boosted by platform-native content like podcast visuals or mentions.

‍

X serves as a complementary channel to his more structured and analytical LinkedIn presence. It offers a space for Guido to maintain visibility, participate in trending AI discussions, and stay connected to fast-moving conversations. While not his primary engagement platform, it’s valuable for signaling relevance and keeping a pulse on the AI and tech communities in a lighter, more frequent format.
