Episode 12: How to Win on LinkedIn in 2025 - A Founder’s Guide to Real Engagement

Logo of Adopter - the marketing agency for deep tech and climate adaptation.

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.

FAQs

  1. What is the LinkedIn algorithm prioritising in 2025? 

LinkedIn's algorithm in 2025 places weight on native video content, saves, and comments - particularly comments that arrive within 60 minutes of a post going live. Posts that keep users on the platform for longer and bring them back later perform better. Research by analyst Richard van der Blom, based on analysis of thousands of posts, found that 72% of LinkedIn users are on mobile, which reinforces the platform's shift toward vertical video formats.

  1. Why do founder accounts outperform company pages on LinkedIn? 

LinkedIn is placing increasing weight on individual creator accounts rather than brand pages. Founder and CEO accounts tend to have broader networks, built through speaking events and interviews, and posts from individuals are more likely to be shown to a wider audience once they reach a critical mass of engagement. Personal accounts also allow for the authentic, human tone that performs better than polished brand content.

  1. What does "authenticity" mean in practice for LinkedIn content? 

Authenticity on LinkedIn means content that reflects genuine expertise, is published in a personal voice, and responds to real events in a timely way. It does not mean professional production quality. Keddie cites Jay Lipman of Ethic as an example: informal videos filmed at events such as New York Climate Week, published while the event is still running, with strong expert commentary and no promotional framing.

  1. How should climate tech companies reframe their messaging in 2025? 

Keddie and Jaworski argue that leading with sustainability as the primary value proposition is becoming less effective, both because of reduced policy tailwinds and because the market expects climate tech solutions to perform better, not just more sustainably. The recommended shift is toward resilience: framing solutions in terms of customer risk reduction, supply chain reliability, regulatory compliance, and national energy or food security, depending on the sector.

  1. How should a climate tech startup get started with LinkedIn content? 

Jaworski recommends starting with easy wins rather than a full platform overhaul. The first step is to review whether the CEO and co-founder profiles are active and well-used, since these accounts typically have the largest networks and the most direct path to engagement. Once the highest-value personal account is active, the next step is to identify other team members - such as a CTO or commercial lead - who can contribute expert knowledge. Keddie adds that a content audit is a useful starting point to see what is already performing and where the gaps are.
