Episode summary

Katherine Keddie and Matt Jaworski, co-founders of Adopter, discuss LinkedIn strategy for climate tech founders on Episode 12 of Scaling Green Tech.The episode covers two related shifts that founders need to act on in 2026. The first is structural: LinkedIn's algorithm now prioritises native vertical video, personal creator accounts, and content that drives saves and comments within the first 60 minutes of posting. According to annual LinkedIn research by analyst Richard van der Blom, 72% of LinkedIn users access the platform on mobile - a fact that shapes everything from video format to how graphics are sized. The second shift is strategic: climate tech messaging that leads with sustainability is increasingly ineffective. Keddie and Jaworski argue that resilience - covering customer risk, energy sovereignty, and national food security - is now the more accurate and more persuasive framing for most climate tech solutions.This episode is relevant for climate tech founders developing a personal brand, startup marketing teams planning a LinkedIn content strategy, and CTOs or technical leads considering how to communicate expertise to a non-specialist audience.

Key takeaways

  • According to Richard van der Blom's annual LinkedIn report, 72% of LinkedIn users access the platform on mobile, making vertical video format and mobile-optimised graphics a practical necessity rather than a preference.
  • Native video uploaded directly to LinkedIn performs better than links to external platforms such as YouTube. Content designed for a vertical phone screen has the strongest reach.
  • Comments arriving within the first 60 minutes of posting are a significant ranking signal for LinkedIn's algorithm. Saves - which bring users back to the platform later - are weighted alongside comments as indicators of content value.
  • Jay Lipman, founder of Ethic, dedicates less than 10% of his LinkedIn content to his business. The rest is expert commentary on nature and finance, published quickly in response to events such as New York Climate Week. His approach demonstrates that timely, issue-led content from a founder account drives stronger engagement than brand promotion.
  • AI-generated content that creates false dichotomies or shallow controversy is becoming easier for audiences to identify and less likely to perform. Authentic personal voice, expert knowledge, and timely commentary are the distinguishing factors for content that builds engagement.
  • CEO and founder accounts typically hold the largest professional networks due to speaking engagements and media appearances. Keddie and Jaworski recommend starting with the CEO profile before expanding to other team members, as it represents the highest-ROI entry point for personal brand content.
  • Climate tech messaging is shifting from sustainability as a primary value proposition to resilience - covering customer risk reduction, energy sovereignty, and adaptation to climate-driven disruption. Keddie argues this framing more accurately reflects the value many climate tech solutions already deliver, and better matches current investor and customer expectations.
