Everyone is chasing AI efficiency. Fewer people are talking to their customers. That gap is where brand moats are built right now - and the companies that figure it out before everyone else wakes up are going to win the next decade of B2B marketing.

ㅤ

David Walsh sits down with Mark Jung, founder of Known, to break down what's actually broken in B2B content, how LinkedIn's algorithm has fundamentally changed, and why the brands that get emotionally close to their audience will be on every buyer's day one list when it matters. Mark has driven over 1 billion organic LinkedIn impressions across hundreds of B2B brands. He is, in David's words, the LinkedIn scientist - and this conversation earns the title.

ㅤ

Mark pulls from six years of LinkedIn data, hundreds of brands, and a near-obsessive study of LinkedIn's own engineering papers to explain what's changed, why it changed, and exactly what to do about it. He also gets specific about the mistakes most creators are making right now - and the mindset that separates the ones who compound from the ones who plateau.

Guest Bio

Mark Jung is the founder of Known, a full-service organic LinkedIn agency for ambitious B2B brands. Alongside business partner Daniel Murray of The Marketing Millennials, Mark has driven 1,016,918,065 organic impressions on LinkedIn across 2024 and 2025, grown a combined 2.19 million GTM followers across personal brands and company pages, and scaled to $1M+ ARR in 47 days after launch. Known operates as a stealth agency - they don't name clients - but their results speak for themselves: net-new pages grown from zero to 25,000 followers, brands taken from 2,000 to 50,000+ company page followers, and LinkedIn's Top Startup Award won on behalf of the brands they work with. Mark has spoken at HubSpot's INBOUND and advises a range of B2B startups. He currently lives in the Cayman Islands.

What We Cover

1. Why boring is how you die: Mark's core philosophy from management consulting to SaaS - great marketing doesn't feel like marketing, and the moment it does, you've lost. He explains why brands chasing AI efficiency have traded proximity to their customer for productivity, and why that's a dangerous trade.
2. The chicken dish at the wedding: Mark's framework for brand positioning. Chicken is safe. Nobody remembers it. Brands that refuse to take a stance, offend their non-ICP, and show up with real conviction are the only ones that build raving fans - and a moat.
3. Three tips for more authentic LinkedIn content: Be capital-YOU (your lived experience is the one thing AI can't replicate), mine your winning comments using Toyota's Five Whys to find the emotion underneath, and apply the Rule of One - one audience, one key point, one emotion per post.
4. How LinkedIn's algorithm actually works now: Mark breaks down LinkedIn's shift from separate compute-heavy systems to a unified LLM-based model built around a MoE (Mixture of Experts) architecture - and what that means for how your content gets ranked and distributed.
5. Cohort seeding: LinkedIn is now gut-checking whether your profile promise and your actual engagement match. Mark explains how the algorithm tests your content in its first 60 minutes, what it's looking for, and why your LinkedIn title matters more than it ever has.
6. The lost in distance problem: LinkedIn's own engineering research found 15.9% better performance when they scanned the beginning and end of content rather than analyzing everything. Your first 200 to 270 characters carry the majority of the algorithmic weight. Mark explains what that means for how you write.
7. The right way to use links on LinkedIn: Stop putting links in the comments. Mark walks through three more effective approaches - including the 15-minute method he uses to capture organic engagement before adding a link, and why resource posts drive saves and sends at scale.
8. The day one list and mindshare marketing: A Google and Bain study found that 8.9 out of 10 B2B buyers purchase from a day one list - a shortlist built over months or years, not at the moment of purchase. Only 3 to 5% of your market is buying at any given time. Mark explains why the other 95% is where the real game is played.
9. Distribution is the moat: Mark's big bet for the next five years - owned audience, organic reach, and deep community relationships will outlast every other competitive advantage in B2B. Products converge. Features get copied. An audience that trusts you compounds.
10. The Milli Vanilli effect: Mark Cuban's framework for why audiences will return to what feels hyper-authentic. Mark applies it to the future of LinkedIn and explains what that means for the brands building now.
