SellsMentoring, a community and a podcast for senior executives moving into fractional, advisory and board work
PeriodOct 21 – Nov 5
Ideal client: senior executives in the second half of their career (finance directors, CEOs, COOs, CMOs) ready to replace one employer with a portfolio of clients and board seats.The challenge: The mentor writes for senior executives weighing a fractional career, and other coaches and consultants read along. A small, loyal audience reacts to almost everything. Which posts bring the executives who would sign up next?
Key takeaways
Almost half the readers are buyers.62 of the 139 people who reacted are senior executives and founders: 44.6%.
Spotlights bring the most.The two member spotlights reached 30 and 22 senior executives. No other post reached more than 14.
7 senior executives are Hot right now.They reacted to 5 posts or more. Five of them reacted to all 22.
01
Who actually reads you, and what the LinkedIn algorithm changed
The mentor posts about the arithmetic and the joy of fractional leadership: four clients instead of one employer, board seats, age-diverse teams, plus podcast episodes and member spotlights. 22 posts between 21 October and 5 November, most at 10 a.m. UK time.
The LinkedIn algorithm shows a post first to the people who reacted to the last ones. On a profile where a loyal group reacts to almost everything, reach can look steady while the new executives stay out of sight. Who reacted tells them apart. We sorted every person who reacted by role.

Senior executives and founders are the largest group: 62 people, almost half. Many already work as fractional CFOs, COOs and CMOs, the people the mentor's community is built for.
37 coaches, consultants and service providers make up the peers. They help reach, and they rarely join an executive community. The pool is small, so a few regulars weigh a lot: 5 people reacted to every one of the 22 posts.

What to post on LinkedIn to reach senior executives
Most mentors judge a post by its reactions. A mentor who sells should judge it by who reacted.
We tagged each of the 22 posts by topic, then measured the share of senior executives and founders among the people who reacted, and how many each post reached.

6 rules for LinkedIn engagement from senior executives
These rules come from what worked on the mentor's own profile, and from the best-performing posts by fractional leaders, executive search consultants and career coaches on LinkedIn over the last 3 months.
1
Celebrate one member by name. A spotlight gives the member a reason to share, and their own network of senior people comes with them. It is also proof that the community works, without a sales line.On this profile: the two member spotlights reached 30 and 22 senior executives and founders. No other post reached more than 14.
Write the arithmetic out. Days per client, clients per month, income against hours. Executives trust sums they can redo on their own numbers more than any promise of freedom.On this profile: the twelve fee earning days question reached 14 senior executives and founders, the most of any post outside the spotlights.
Open on one line with an age or a number in it. “You can lose your VP role at 48.” A first line with one age or one number stops a senior reader faster than a reflection does. Keep the reflection for line three.Across the niche: Kristof Schoenaerts' four-line age timeline drew 962 likes, the most in our 90-day sample.
Put one real room on the page. One board meeting, one client's sentence, one set of sums. A scene shows the mentoring itself, where a general point only describes it.Across the niche: Colleen Paulson's post opening on one client's sentence drew 150 comments on 117 likes.
Answer the question executives ask in private. When to take a first board seat, what to charge, how to tell the family. Say the doubt out loud, then give one test they can apply this week.On this profile: the board seat post reached 58.3% senior executives and founders, above the profile average of 44.6%.
Give your answer first, then ask for theirs. The mentor already ends every post on a question. Starting with one honest answer of your own makes it easier for a senior reader to add theirs.On this profile: the post that was only a question about multi-generational teams brought 25 reactions and 10 senior executives and founders.
When senior executives read: the best time to post on LinkedIn for fractional leadership mentors
We compared the share of senior executives and founders by the day and the hour each post was published (UK time). Only two time slots had 3 posts or more: 8 a.m. and 10 a.m.

Each post follows the rules above, in the mentor's voice. Swap in your own details before posting: the real member, client and figures are what make it land.

The finance director who did the sums at 57Rules 1 and 3: one member, one age, one set of numbers. Modelled on Jenny Stojkovic's Anne Boden story and the mentor's own spotlights.
Hook
At 57, he assumed a portfolio career meant a pay cut.Today we are celebrating a Portfolio Executive who spent twenty-six years in finance, the last nine as group finance director of a manufacturing business, and who left without a plan B and without any wish to retire.For his first six months he did what most capable people do. He waited for the right permanent role to appear, and quietly told himself that the fractional model was for other people.Then he sat down and did the arithmetic properly, client by client.Three clients. Eleven fee earning days a month. Within a few percent of his old salary.A year on, he is the part-time finance director of a family-owned engineering firm, a fast-growing software business and a charity, and he took his first non-executive seat at 58.What he says surprised him most was not the income. It was how much he enjoys the work again, and how much of his judgement each client actually uses.He is also a valued member of the Portfolio Executive Community.If you would like to show your support, save this post and say hello to him in the comments.What assumption about your own next chapter have you never actually tested?#PortfolioExecutive #FractionalLeadership #SecondHalfCareer #CareerRedesign #FractionalCFO

The twelve days worksheetRule 2 plus a lead magnet: write the sums out, then give the sheet. Modelled on Aleksandar Stojanović's “Comment MODEL” post.
Hook
Four clients. Three days each. Twelve days a month.That is the arithmetic I set out with senior executives at the very start, before we talk about positioning, LinkedIn or anything else.Most people have never written it down. They carry a vague sense that leaving a salaried role means accepting much less, and they make a very large decision on the strength of that sense alone.So we build it, line by line, on one page:→ The day rate you would genuinely be comfortable quoting
→ The number of clients you want, not the number you fear
→ The days each one realistically needs from you every month
→ The months a year you actually want to work
→ The runway you need before the fourth client arrivesThe answer is rarely the one people expected. Usually it is closer to their old salary than they feared, at roughly half the hours.I have turned this into a one-page worksheet, with a filled-in example for a former finance director.If you would like it, comment TWELVE and I will send it to you.What would your own sums say, if you did them honestly this week?#PortfolioExecutive #FractionalExecutive #PortfolioCareer #SecondHalfCareer #WorkOnYourTerms

Monday morning, no meetings in the diaryRules 3 and 4: one room, one moment. Modelled on Vinita Win's “Monday morning. 28 years in corporate.”
Hook
Monday morning. Thirty-one years in banking. Nothing in the diary.A former managing director told me that the first Monday after leaving was the strangest morning of his working life. For three decades, other people had filled his week for him, one meeting looking much like another.He said, quite simply: “I did not realise how much of my week was decided by other people.”That was the real transition. Not from employment to unemployment, but from a diary that was given to him to a diary he had to design.We started with one question. Which three days of an ordinary month would he genuinely look forward to?The answer was not more meetings. It was a founder who needed a sounding board, a board that needed someone who had seen a crisis before, and one afternoon a month mentoring a younger leader.Six months later, those three days had become his first three clients.The empty Monday was not the end of something. It was the first honest look at what he actually wanted his working life to contain.What would you put in your own diary first, if nobody else were filling it for you?#PortfolioExecutive #FractionalLeadership #CareerRedesign #SecondHalfCareers #Freedom

Before your first board seat, ask one questionRule 5: the doubt executives keep to themselves, with one test. Modelled on Mircea Tiplea's first-board advice.
Hook
Before your first board seat, ask yourself one question: what would this board teach me?Most senior executives approach their first non-executive role as a reward for a long career. They look for the most prestigious name, the largest company, the seat that will read best on a profile.In my experience, that is usually the wrong way round.Your first board is an apprenticeship. You are learning to influence without executing, to ask the question rather than supply the answer, and to carry responsibility for decisions you will not personally deliver.So I suggest three tests:→ Will I sit next to people whose judgement I genuinely respect?
→ Will I carry real responsibility, not just an advisory title?
→ Would I still want this seat if it paid nothing at all?A charity, a school, a housing association or a small family business will often pass all three far more easily than a glossy advisory board.If you have been sitting on the sidelines of this conversation, send me a message, in complete confidence, and let us work out what your first board could realistically look like.The Portfolio Executive: the home of fractional leadership.Which of those three tests would your first board fail?#PortfolioExecutive #BoardRoles #NonExecutive #Mentoring #SecondHalfCareer
What I wish I had known before my first fractional clientRule 6: give your own answer first, then ask for theirs. Modelled on Aly Sanders' fractional advice round-up.
Hook
What is the one thing you wish you had known before your first fractional client?I will start, and then I would genuinely like to hear yours.Mine is this: your first client is buying your judgement, not your hours.Most senior executives price their first fractional role by dividing their old salary into days. It feels fair, and it feels safe. But it quietly tells the client that they are buying a smaller, part-time version of an employee.The executives who build the strongest portfolios do something different. They describe the problem they will solve, the decisions they will help make and the months it will take. The days follow from that, not the other way round.It took me longer than I would like to admit to learn that. Most of the people I mentor learn it on their second or third client, usually after the first one has taken twice the days it paid for.So, over to you.What would you tell yourself on the day before your first fractional client, if you could?The best answers will go into a short guide for the community next month.#PortfolioExecutive #FractionalLeadership #FractionalExecutive #Mentoring #SecondHalfCareer

From reactions to clients
Content brings senior executives to the profile. It doesn't say when to reach out. Most never comment, so they stay invisible, and an executive reading every post about the arithmetic this month may have taken a permanent role by 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.

FAQ
Every topic brought 46 to 59% senior executives here, so the topic matters less than the format. Member spotlights reached the most per post (26), then the written-out arithmetic. Open on one age or one number, show one real room, and give your own answer before asking for theirs.
For this mentor, Tuesday brought the highest share of senior executives (64.9%, on 3 posts) and Monday the lowest (45.2%). Friday brought the most in total, 82 across 6 posts. The sample is two weeks, so treat it as a direction, not a rule.
This mentor posts about 10 times a week, often twice a day, and 9 senior executives came back 3 times or more in two weeks. A steady rhythm works when each post gives executives something to use. Keep one main post a day at the same time.
Look at who reacts, not how many. Group reactions by role, measure the share of your ideal clients per post, and follow the people who keep coming 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 public reactions on 22 posts published between 21 October and 5 November 2026, and sorted the 139 people by role. Duplicate posts and posts shared to a group page were left out. Comments were not counted, so engagement figures are a floor.
Niche rules come from top posts by fractional leaders, executive search consultants and career coaches over the last 3 months. Role groups are approximate, and some executives sell to the same audience; a Netwarm scan matches people to your own ideal client.
