PeriodSep 28 – Nov 3
Ideal client: sustainability, sourcing and materials leaders at fashion and luxury brands, investors in next-gen materials, and founders of material innovation startups.The challenge: The advisor built a financial model to answer one question: “Is there a business case for sustainability?” The same question applies on LinkedIn. Posts reach designers, consultants and academics as well as brand leaders. Which posts reach the people who sign off on a fiber transition?
Key takeaways
1 in 5 readers is a fashion or materials leader.59 founders, CEOs, directors and VPs in fashion, materials and sustainability reacted in 5 weeks: 21.1% of the 279 people who reacted.
Business-case posts bring the highest share.The two SHIFT business-case posts: 24.2% leaders. The two cohort announcements: 15.4%, on far fewer reactions.
11 leaders came back.They reacted to 2 posts or more. One of them reacted to 3 of the 9. None has reached Hot yet.

Who actually reads you, and what the LinkedIn algorithm changed
The advisor posts about twice a week: the SHIFT business case built with Textile Exchange, the conference panel in Vancouver, news from material innovators, and the Innovation Insider cohort for startups. 9 posts between 28 September and 3 November.
The LinkedIn algorithm shows a post to the people who reacted to the last ones, then to people like them. Sustainable fashion is a close-knit feed: brand leaders read it, and so do consultants, designers, researchers and the innovators the advisor works with. Reach can’t tell them apart. Who reacted can. We looked at every person who reacted and sorted them by role.

Fashion and materials leaders are 59 people, about 1 in 5. More than half of them run or lead material, textile and fibre innovation companies; about a quarter lead at fashion, luxury and retail brands; a few invest in the space.
Peers come close: 50 consultants, advisors, academics and creatives. They spread the posts, and they rarely hire an advisor. Most of everyone else are sustainability and sourcing professionals below director level: the teams who build the case internally, and often the first contact at a brand.

What to post on LinkedIn to reach fashion and materials leaders
Most advisors judge a post by its reactions. An advisor who sells should judge it by who reacted.
We tagged each of the 9 posts by topic, then measured the share of fashion and materials leaders among the people who reacted. With 2 or 3 posts per topic, read the gaps as a direction, not a rule.

6 rules for LinkedIn engagement from fashion and materials leaders
These rules come from what worked on the advisor’s own profile, and from the best-performing posts by sustainable fashion, circularity and sustainability strategy creators on LinkedIn over the last 3 months.
1
Open on the money question, not the mission. “Is there a business case for sustainability?” is the question brand leaders are asked in their own meetings. A post that opens on it reads as help, not as advocacy.On this profile: the business-case post had the highest share of leaders of any post with 20+ reactions, 24.6%.
Speak to the people who were in the room. “Who was at the Textile Exchange conference in Denver in 2022?” calls the people who were there by name and gives everyone else a reason to read on.On this profile: that post reached 21 fashion and materials leaders, the most of any post.
Tell one brand, one test, one result. One concrete case (a brand, what it tried, what happened) shows the advisory work better than a trend summary.Across the niche: Vojtech Vosecky’s one-repair story drew 1,722 likes and 113 comments.
Say the CFO’s objection before the CFO does. “It costs more” is what every leader hears internally. Naming it, then answering it, is what the advisor’s SHIFT work does in a meeting.Across the niche: Robert Höglund’s cost-neutral post drew 29 comments on 72 likes.
Put the whole system on one page. A diagram a leader can take to the next internal meeting travels further than a long post. The advisor’s SHIFT framework is already built for it.Across the niche: Antonio Vizcaya Abdo’s Patagonia diagram drew 1,529 likes and 100 comments.
Open on names leaders know. A brand name in the first line (G-STAR, Miu Miu, LVMH) tells brand leaders the post is about their world before they read the material science.On this profile: the G-STAR post reached 20% leaders on 32 reactions.
When fashion and materials leaders read: the best time to post on LinkedIn for sustainable fashion advisors
We compared the share of fashion and materials leaders by the day each post was published. With 9 posts, most days have one post, and no 2-hour slot has 3 posts or more, so there is no hour to compare.

Keep the business-case and diagram posts for midweek and Friday, around midday Paris time, which also reaches the US East Coast in the morning. Two posts a week is enough if each one gives leaders something to use.

5 posts ready to publish to target fashion and materials leaders
Each post follows the rules above, in the advisor’s voice. Swap in your own details before posting: the real brand story is what makes it land.
1Ready to postObjection, answered
The question finance asks firstRule 4: say the CFO’s objection before the CFO does. Modelled on Robert Höglund’s “cost-saving or cost-neutral” post.
Hook
“What’s the payback?” is the first question finance asks about a fiber transition.Most sustainability teams answer with impact.Tonnes of CO2. Litres of water. Hectares of better farming.All true. All important.And finance still asks the same question, because impact is not the language a budget is approved in.Over 18 months of building a business case for preferred cotton, wool and polyester, we heard the same pattern again and again:→ Brands quantify the extra cost of the material
→ They rarely quantify what it saves or protects
→ So the transition looks like a pure cost on paperThe answer is not a better impact slide.It is putting three numbers next to each other:1/ The investment: what the transition really costs, year by year
2/ The risk reduction: regulation, supply disruption, price swings
3/ The value created: margin, brand, access to customers and retailers who now ask for itWhen all three sit on one page, finance stops asking “why should we?” and starts asking “how fast?”.Impact pays. But only if you show the whole bill.Which of the three numbers does your brand calculate today?
Visual · Single imageThree columns on one slide: Investment, Risk reduction, Value created. One line under each, no figures.Check before postingKeep the three numbers generic, or swap in a real (anonymised) brand result from the SHIFT work if you can share one.
What 30+ stakeholders told us about the fiber transitionRule 2: speak to the people who were in the room. Modelled on the “Who was at the Textile Exchange conference in Denver in 2022?” post, the one that reached the most leaders.
Hook
Who was in our SHIFT session in Vancouver? Here is what we didn’t have time to say.To build SHIFT, we spoke with 30+ stakeholders and had 4 brands peer-review the financial model.Three answers kept coming back.1/ Environmental impact alone rarely unlocks the budgetIt opens the conversation. It almost never closes it.2/ Brands quantify the costs of a material, not its benefitsThe premium for preferred cotton is in every spreadsheet. The avoided risk is in none.3/ Departments work in silosSustainability teams rarely speak the “love languages” of finance, sourcing, marketing and compliance. So the transition stays a project, not a decision.None of this is a lack of good intentions.It’s a lack of one shared case that every department can read in its own terms.That’s what we built SHIFT for: a framework and a financial model that each brand can run with its own data.If you were in the room, what would you add?And if you weren’t, the teaser dashboard is in the comments.
Visual · Carousel4 slides: the 30+ stakeholders and 4 peer-reviewing brands, then one finding per slide in large type.Check before postingThe three findings come from the SHIFT research shared after the conference: check the wording matches what you published with your partners.
What a brand pilot of a next-gen material really needsRule 3: one brand, one test, one result. Modelled on Vojtech Vosecky’s Nudie Jeans repair post.
Hook
The material passed every lab test. The pilot still almost died in a pricing meeting.I’ve seen this scene more than once, on both sides of the table: the innovator’s and the brand’s.The innovator brings a material that works.The brand’s innovation team loves it.Then the capsule reaches the people who own margin, volume and claims. And the questions change:→ What does it cost at 10x the pilot volume?
→ Can our current mills and suppliers run it?
→ What can marketing legally say about it?
→ Who pays for the first year?When nobody has prepared those answers, the pilot becomes a press release and stops there.The pilots that scale have one thing in common.The business case was written before the first meter was produced, with a price path, a supplier plan and a claim that compliance has already signed.A pilot is a test of the material.Scaling is a test of the business case.If you are an innovator: which of those four questions do brands ask you first?
Visual · Single imageA photo of a material swatch on a meeting table next to a printed price sheet.Check before postingUse a real pilot you have advised (anonymised if needed). The scene in the first line must be true.
The fiber transition on one pageRule 5: put the whole system on one diagram. Modelled on Antonio Vizcaya Abdo’s Patagonia circularity diagram.
Hook
What does each department need to hear before a brand moves to preferred fibers?
⬇️I drew this map for the workshops we run with leadership and cross-functional teams.Five departments. Five different questions.→ Finance
What is the investment, and when does it pay back?→ Sourcing
Can our suppliers deliver it, at what volume and what price?→ Marketing
What can we say, and will customers care?→ Compliance
Which regulations does this help us meet, and which risks does it reduce?→ Sustainability
What is the real impact, and how do we measure it?Most business cases answer the last question very well.The transition happens when the other four are answered too, in their own terms, on the same page.That is the shift in mindset behind SHIFT: from siloed views to alignment, from cost to holistic value, from short-term to long-term.Which department is the hardest to convince in your organisation?Save this for your next internal meeting.

The 10 questions to answer before you pitch a fiber transitionRule 1: open on the money question. Modelled on the “Is there a business case for sustainability?” post, the highest share of leaders on the profile.
Hook
Is your fiber transition ready for the finance meeting? 10 questions to check.Most internal pitches for preferred cotton, wool or polyester are strong on impact and thin on everything else.Here is the checklist we use before a brand takes its case to the board.Investment
1/ What is the extra cost per year, at today’s and at target volumes?
2/ Who pays for it: one department, or shared?Risk
3/ Which regulations does the transition help you meet?
4/ Which supply risks does it reduce?
5/ What happens to your costs if you don’t move?Value
6/ Which customers or retailers now ask for it?
7/ What can marketing claim, and has compliance signed it?
8/ Does it protect or grow margin over five years?Alignment
9/ Has each department seen the case in its own terms?
10/ Who owns the decision, by name?If you can’t answer three or more, the case isn’t ready yet. That’s fine. It’s much easier to fix before the meeting than after.I turned the checklist into a one-page PDF, with a note on where to find each number.Comment “SHIFT” and I’ll send it to you.

From reactions to clients
Content brings fashion and materials leaders to the profile. It doesn’t say when to reach out. Most never comment, so they stay invisible, and a sourcing director who read the SHIFT launch in October may have hired another advisor by the spring.
On LinkedIn, the right moment to start a conversation is when someone keeps coming back. We call that Hot: 5 or more points over 90 days, where a reaction counts 1, a repost 2, a download or a reply 4. In this sample, 11 leaders came back to 2 posts or more and none has reached Hot yet: a full scan of every reaction shows who is closest.

How we made this playbook
We read the public reactions on 9 posts published between 28 September and 3 November 2026 (the first 100 people who reacted to each), and sorted the 279 people by role. Reposts of other people’s posts were left out. Comments were not counted, so engagement figures are a floor.
Niche rules come from top posts by sustainable fashion, circularity and sustainability strategy creators over the last 3 months. Role groups are approximate, and some leaders sell to the same brands; a Netwarm scan matches people to your own ideal client.
