Electrical and digital building infrastructure: data center power, cooling and cabling, energy transition solutions, essential building solutions
PeriodOct 1 – Nov 5
Ideal client: data center operators, electrical distributors, building and energy decision-makers, partners and investors who follow the group's growth plan.The challenge: The CEO posts about once a week, on results, strategy and data center power. Most reactions come from the group's own teams. Which posts reach the customers, partners and investors outside the company?
Key takeaways
1 in 4 readers is a decision-maker.67 CEOs, founders, directors, VPs and partners outside the group reacted to 3 posts: 23.8% of everyone who reacted.
Numbers first, recaps last.The nine-month results post brought 31% decision-makers. The Capital Markets Day recap brought 19%.
7 came back.7 decision-makers reacted to 2 of the 3 posts, among them an operations director at a global data center operator.

Who actually reads you, and what the LinkedIn algorithm changed
The CEO posted 3 business posts between 1 October and 5 November 2026: the Capital Markets Day in Singapore, data center power, and the nine-month results. A fourth post, a message of support after the destruction of Limoges City Hall, is left out of this analysis.
The LinkedIn algorithm shows a post first to the people who reacted to the last ones. For a group CEO, that is the company's own teams: they react fast and in numbers. Reach can't tell colleagues from customers. Who reacted can. We read the first 100 reactions on each post and sorted the people by role.

Audience by roleThe 282 people who reacted, by roleFree
The group's own teams and students are the largest group: 97 people whose headline says so, about 1 in 3, and more whose headline doesn't. They give every post its first push, and they are not who the CEO is trying to convince.
The 67 decision-makers come from data center operators, electrical distribution, energy, consulting, law and investment. That mix is the audience a listed industrial group writes for: customers, partners and the people who follow its numbers.

What to post on LinkedIn to reach decision-makers
A CEO's post is judged by its reactions. A CEO who wants customers and investors to read should judge it by who reacted.
We tagged each of the 3 posts by topic, then measured the share of decision-makers among the first 100 people who reacted.

6 rules for LinkedIn engagement from decision-makers
These rules come from what worked on the CEO's own profile, and from the best-performing posts by CEOs and leaders in data center, power and electrical infrastructure on LinkedIn over the last 3 months.
1
Put the number in the first line. Customers and investors scan. A growth figure in line one tells them why to keep reading; the thank-you to the teams can close the post.On this profile: the results post, which opened on +22% sales growth, brought 31.3% decision-makers, the highest share.
Open on the customer's constraint, not on the company. “Power is becoming a defining challenge” is the sentence a data center operator says in meetings. Start there, then show how the group answers it.On this profile: the data center power post opened on that constraint and brought 24 decision-makers in its first 100 reactions. Across the niche: Guy Massey's “Where does a data centre get its power?” drew 106 comments.
Give them one sentence they can repeat. “Engineering Every Megawatt for More Compute” is already a line people can quote. Put it first, in quotes, the way an interview headline would.Across the niche: Peter Voser's post opening on one quote from a Bloomberg interview drew 323 likes.
Show the site and name the hosts. A plant, a customer's campus, a trade show booth: one place and the people who opened it. Naming customers and partners brings their networks to the post.Across the niche: Giordano Albertazzi's post on a visit to an AI data center campus drew 583 likes.
Say what customers told you. After an event, share the one theme you heard from customers, not the agenda. Decision-makers react to what their peers worry about.Across the niche: Nick Chaset's post on what he heard at two dinners with hyperscalers and builders drew 18 comments on 71 likes.
Turn an event recap into one takeaway. A recap that starts with the trip reads as internal news. Start with the target the event announced, then the trip.On this profile: the Capital Markets Day post opened on “Back from Singapore” and brought 19% decision-makers, the lowest share of the 3 posts.
When decision-makers read: the best time to post on LinkedIn for electrical infrastructure CEOs
We compared the share of decision-makers by the day each post was published. With 3 business posts and a fourth on a Sunday, each day rests on one or two posts: read it as a first signal. Each post went out at a different hour, so there is no hour to compare yet.

Thursday brought the most decision-makers in total: 50 across 2 posts (the Capital Markets Day and the nine-month results). Monday's data center post brought 24%, Sunday's message of support 23%.
Days move the share only a little. What moved it was the opening line. Keep results and announcements on their market days, and put the posts written for customers (data center power, site visits) early on Monday to Thursday, Paris time, when Europe is at work and Asia is still online.

5 posts ready to publish to target decision-makers
Each post follows the rules above, in the CEO's voice. Every figure comes from the group's own published posts; swap in the details only you know before posting.
1Ready to postMilestone
From less than €1 billion to more than €3 billionRule 1: the number in the first line. Modelled on Antonio Neri's “Record results” post.
Hook
Less than €1 billion in 2021. More than €3 billion expected in 2026.That is the size of our data center business, and the speed of the transformation at Legrand.Three choices made it possible:→ Being present across the whole white space: power, cooling, cabling and digital solutions
→ An open-architecture, modular approach, so customers can build at their own pace
→ Targeted acquisitions, 7 since the beginning of this yearIn the first nine months, data centers grew close to +40% organically.The constraint our customers share is no longer space or servers. It is power. Every available megawatt has to count.That is why our message is simple: Engineering Every Megawatt for More Compute.Thank you to our customers for their trust, and to our teams who build this every day.What is the biggest constraint on your next data center project?#LegrandImprovingLives
Visual · Single chartTwo bars: data center sales 2021 (less than €1bn) and 2026 expected (more than €3bn). Group colours, no other figures.Check before postingConfirm the €1bn / €3bn wording matches the Capital Markets Day release.
Where does a megawatt go?Rule 2: open on the customer's constraint. Modelled on Guy Massey's “Where does a data centre get its power?” post.
Hook
Where does a megawatt go once it enters a data center?Not all of it reaches the servers.Part of it is lost on the way. Part of it goes to cooling. Part of it sits unused because the room was not designed for today's racks.At a time when power is the first limit on data center growth, each of those losses is compute our customers do not get.This is how we look at it at Legrand:→ Power: distribute it as close to the rack as possible, with fewer losses
→ Cooling: remove the heat where it is created
→ Cabling: keep the room ready for the next generation of equipment
→ Digital: measure every rack, so nothing runs blindFour areas, one goal: more compute from the same megawatt.Operators who think about all four at the start build faster and waste less.Which of the four is the hardest on your sites today?#LegrandImprovingLives
Visual · DiagramOne megawatt entering a data hall, split into four arrows: power, cooling, cabling, digital. No percentages.Check before postingAsk the data center team to check the wording of each of the four areas.
Data centers get the headlines. Buildings are where we started.Rule 3: one sentence they can repeat. Modelled on Peter Voser's interview-quote post.
Hook
“Data centers get the headlines. Buildings are where Legrand started, and where we keep investing.”I say this often, because our 2030 plan rests on three focus areas, not one:→ Data centers, where sales are expected to exceed €3 billion in 2026
→ Energy transition, supported by long-term electrification needs throughout the world
→ Essential solutions for buildings, our historical businessThe third one does not trend on LinkedIn. It is where our customers and installers meet us every day: in homes, offices, schools and hospitals.We will continue to invest there in growth, new products and customer experience.Because a group that grows on one engine is fragile. A group that grows on three is built to last.Which of the three do you see changing fastest in your market?#LegrandImprovingLives

What I saw on the siteRule 4: show the site and name the hosts. Modelled on Giordano Albertazzi's data center campus visit.
Hook
This week I spent a day on one of our production sites, with the teams who build our data center solutions.Close to +40% organic growth in the first nine months does not come from a slide. It comes from teams who have to deliver more, faster, with the same quality.What struck me:→ Lines rearranged to follow customer demand
→ Engineers working directly with customers on their next projects
→ Teams proud of what leaves the siteOur customers are building at a speed this industry has never seen. Being their partner means keeping that pace on every site.Thank you to the teams for the welcome and the frank conversations.#LegrandImprovingLives

What customers asked us in SingaporeRule 5: say what customers told you. Modelled on Nick Chaset's post on what he heard from hyperscalers and builders.
Hook
At Data Centre World Asia in Singapore, I asked customers and partners one question: what is slowing you down?One word came back in almost every conversation: power.Not space. Not servers. Power.The ones who move fastest share three habits:→ They design power, cooling and cabling together, from the first drawing
→ They choose modular systems, so a site can grow one block at a time
→ They measure every rack from day oneThat is why we came to Singapore with an open-architecture, modular portfolio, and one message: Engineering Every Megawatt for More Compute.Thank you to everyone who stopped by the booth and shared their projects with us.What is slowing down your next project?#LegrandImprovingLives

LinkedIn lead generation: lead magnets that work to target decision-makers
Reactions show interest. A download or a sign-up shows intent. For a listed group, the strongest offer is the expertise its teams already have, packaged for one decision.
In data center, power and electrical infrastructure, these formats get shared the most:
Format 1The research publicationA short study on one industry problem (grid connection, power density) that customers forward to their board.
Format 2The report webinarA report presented live by the experts who wrote it, with a sign-up link.
Format 3The talk recordingA conference talk shared for the people who missed it.
Format 4The engineer's explainerA technical blog by one of the group's engineers, shared by the executive with one line of context.
Our pick for you: “The Megawatt Checklist”One page built from the four areas the CEO already names (power, cooling, cabling, digital): the questions an operator should answer before a new data hall, written by the group's data center engineers. Offer it at the end of post 2, “Where does a megawatt go?”.With a Reveal link, every person who downloads it is shown by name, with their role and how warm they are.

From reactions to clients
Content brings decision-makers to the profile. It doesn't say who to talk to. Most never comment, so they stay invisible, and a data center operator reading every post this autumn may sign with another supplier next 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. With 3 posts read, nobody has reached that yet: 7 decision-makers are on their way, with reactions on 2 of the 3 posts.

FAQ
Lead with the number or the customer's constraint, not the company. Here, the results post opening on +22% growth brought 31% decision-makers; the recap opening on the trip brought 19%.
On 3 posts, Thursday brought the most decision-makers: 50 across 2 posts, 25.1%. Monday brought 24%. The gap is small: the first line matters more than the day.
Once a week is enough when every post gives customers and investors something to use: a figure, a constraint, a site. This CEO posted about once a week and reached 67 decision-makers in 5 weeks.
Look at who reacts, not how many. Separate your own teams, measure the share of customers, partners and investors per post, and follow the ones who come back. A free Netwarm scan does this for you.
Yes. Netwarm only reads public reactions to your own posts. It never logs in as you, never asks for your password, and never messages anyone for you.
How we made this playbook
We read the first 100 public reactions on each of 3 business posts published between 1 October and 5 November 2026, and sorted the 282 people by role. A fourth post, a message of support after the destruction of Limoges City Hall, was left out of the content analysis; its day appears in the timing chart only. Comments were not counted, so engagement figures are a floor. The 5 November post was read on the day it was published.
Niche rules come from top posts by CEOs and leaders in data center, power and electrical infrastructure over the last 3 months. Role groups are approximate, and the group's own teams are counted only when their headline says so.
