Koos & Perpetuum · LinkedIn session · 21 October 2026
LinkedIn session, 90 minutes. Goal: everyone leaves with a post they can publish today. We start with where we are, then two types of writers, then 30 minutes of research with the skill, then a short block on how a post works, and we end writing. Kasper is on holiday: record the session.

We take two more build weeks, until the end of the week of 2 November. The cluster ICP list and the switch definitions are in place, the content theme is chosen: what’s worth building. The playbooks, the LinkedIn assets and the tools get the extra time. From the week of 9 November the playbooks run, and the webinar moves to the week of 7 December. The 29 October session keeps its date.

Goal of the partnership

Building Koos’ marketing engine: inbound and outbound brought together in one integrated marketing and sales approach, aimed at a chosen set of accounts.

Inbound SEO/GEO · content · nurturing Outbound LinkedIn · email · signals relevant conversations at target accounts
The goal from the context day, unchanged. One approach for marketing and sales together, aimed at a chosen set of accounts. This is the change for the team: no hand-off from marketing to sales, but one plan that both run.

Cluster ICP

Organisations with an existing consumer-facing digital product or service, committed to a better customer experience, whose own team can’t deliver it.

A consumer-facing digital product, in use today
A public ambition for a better customer or user experience
An own team that lacks the people or the seniority
QMobilityKNMIJustisINGCareemRabobankDen Haag
The cluster sentence from the deal analysis of 23 September. Every won deal fits it: QMobility, KNMI, Justis, ING, Careem, Rabobank, Den Haag. The open dots are accounts that fit but do not know Koos yet. An account that fails one of the three checks stays off the list.

Content theme

Theme

What’s worth building. AI made building cheap. Every next step now needs proof first.

Business

Leadership has seen the speed, not the result. CEOs say a quarter of their AI initiatives delivered the return they expected. IBM CEO Study, 2025

Government

One step earlier: is AI the right answer here at all? Start from the person, not the technology.

29 October

Koos’ session When you can build anything, what is worth building? Every post this month can point to it.

build go / no-go 25%
Building got cheap
So teams build more than ever
Only 25% delivered the return CEOs expected
Now decide before you build
Three weeks, then go or no-go
What you build gets used
The theme we chose for the first ABM run. For business clients the angle is proof: leadership invested in AI and wants to see results before the next step. For government, from the talk with Michaël on 14 October: start with the caution. Is AI the right answer, where is resistance legitimate, start from the human perspective. The 29 October session is the natural call to action in posts this month.

Two types of writers10 min

Which one are you?

Your homework goes into the research skill. You leave with an angle board.

How a post works10 min

The first two lines, hooks, length and formats

Writing35 min

One angle, one post, ready to publish

Before you go5 min

Post, share, pick your language and rhythm

90 minutes, strictly timeboxed. The research block stops at 30 minutes, even if the board is not perfect: the writing time matters more. End result: a post per person, ready to publish.
Where we areTwo writersFinding ideasWriting the post

Two types of writers

Beethoven
Mozart
Both need input
Theory, ten minutes. The point: there is no single right way to get to a post. We facilitate both.

Two types of writers

Beethoven

Starts writing and finds the point on the way.

Starts withA moment, a feeling, a first line
ThenWrites it all out, cuts, rewrites
NeedsA spark, and permission for a messy draft

Mozart

Thinks it through first, then writes it once.

Starts withA theme and some research
ThenOutlines hook, point and proof, then writes
NeedsInput and a structure

Both need input. That is where we start.

The classic split in writing advice. Beethoven filled sketchbooks with drafts he crossed out and reworked: he found the music by writing. Mozart, as the story goes, finished pieces in his head and wrote them down once. Ask the room: who recognises themselves in which? Neither is better. Beethovens get stuck when they wait for a plan; Mozarts get stuck without input. The research skill gives both a starting point.

Ik zag vanochtend deze post van Martijn Verspeek, waarin hij aangaf dat hij gek werd van alle AI aanbiedingen en we hem beter konden helpen met zijn lange en vele 💩 sessies.

Well……

A real post from last week, by Joris Rood. Martijn Verspeek wrote that he was fed up with all the companies trying to sell him AI. Joris saw it that morning, admitted he had sent such messages himself, and replied with a 23-second video shot in a supermarket. 54 reactions and 3 comments on 21 October. The point for this block: ideas sit in your own feed and inbox. That is what the skill goes looking for. Click the video to play it; it has sound.

Research skill

1

What you bring

Your LinkedIn profile
Four questions: what you work on, the clients you brought in, the work you love, the subjects you could talk about for hours
Five profiles you like to followhomework
Five blogs, newsletters or sites you readhomework
Your five favourite client moments of the past weekshomework
2

What the skill does

Finds the topics you own, from your profile and answers
Reads what your five profiles post about, and which hooks and formats work for them
Scans your sources, the news and LinkedIn for what’s worth building
Matches what the market talks about to your topics and client moments
3

What you get

Your board in the ABM tool: ten post angles as cards you drag, sort and pick from.

The skill walks you through it. First it asks for your LinkedIn profile and four questions about your work, so it knows which topics are yours. Then it takes the homework: five profiles, five sources, five client moments. It reads what those people post about, scans the market for the content theme, and comes back with ten angles. Every angle has to be yours: a topic you own or a moment you lived. Timebox: 30 minutes, including reading the board.

Where the skill saves the angles: your own board in the ABM tool, under Program > Post angles. Everyone sees everyone's board; only you move your cards. Cards start in Angles; you drag the ones you like to Shortlist and the one you write today to Writing. The cards on this slide are examples, not research. Every card carries the hook and format thinking from the next chapter, so you start writing with a first line, not a blank page.

Create inspiration for your post

Get the skill1 min

Download post-angles.zip from Slack. Drop it into Claude Code and ask: unzip this into ~/.claude/skills/

Connect Gmail and Slack2 min

In Claude, go to Settings > Connectors. The skill reads your past month to find what you could talk about

Start a new session1 min

Close Claude Code and open it again, so it loads the skill and your connectors

Check the Koos connector1 min

Type /mcp and click Koos. Connected is good; needs authentication means sign in with your email link

Run /post-angles15 min

Answer the questions, paste your homework, and click Collect posts when the skill asks

Keep the window open20 min

The skill researches, finds your themes and writes your posts. Your studio fills itself

Everyone works in Claude Code in the desktop app; the Koos connector from the list exercise is the same one, it just has new tools. Do steps 1 to 4 together on screen, then everyone runs /post-angles at their own pace. Gmail and Slack are optional: without them the skill works from the answers, the homework and their own posts, so the subjects rest on less. If the organisation blocks those connectors, skip step 2. Connect them before the new session; a connector added later means starting over. Paul and Sezayi walk around. If /post-angles doesn't show up, the folder isn't in ~/.claude/skills/post-angles or the session is still the old one. If /mcp shows no save_post_studio, the connector points to an old address: add it again from Setup > Connect your AI. The goal of this block: everyone's analysis is running. While it runs, we start on the next chapter.

Reactions and commentsReply to every comment the same day
Three questions for every postDoes it stop the scroll?Does it sound like me?Does the image back the hook?
In the feed people see your photo and name, about two lines of text and the image. Everything else hides behind …more. So you have two options: make your point in those two lines, or make them interesting enough that people click. The image supports the hook, it does not replace it. The post on the slide is an example.

The hook

Make the point

The whole message fits in two lines. Readers who stop there still got it.

Most AI features on the roadmaps we review should not be built. We ask one question first.

Open a loop

Two lines that raise a question only the rest of the post answers.

A civil servant told me she didn’t want AI in her service. Ten minutes later I agreed with her.
A client momentLast Tuesday a product owner asked us…
A clear opinionStop adding AI to your roadmap.
A number with a sourceOne in four AI projects paid off.
Their own questionHow do you know a feature is worth it?
Two strategies for the first two lines. Then four patterns to start from. The examples are illustrations on our theme, not real cases: replace them with your own moments. Tip for the writing block: write three hooks for the same post and pick the best.

Length and format

Short

The point fits above …more. For an opinion, an observation or a client quote.

Long

A story or argument that earns the click. Short paragraphs, one idea, up to 3,000 characters.

Text

A sharp opinion or a short story

effort: low

Image

A photo from your work or one clear visual

effort: low

Carousel

A framework, steps or a before and after, as a PDF

effort: high

Poll

A real question to your audience, with a follow-up on the result

effort: low

Video

You or the work on screen, under a minute

effort: medium
Pragmatic: pick the format that fits the angle and the time you have. For today, text or image. A carousel takes design time; plan it for a later post. LinkedIn has no audio post in the feed, so we leave audio out. The angle board already suggests a length and format per card.

Writing

Pick one card2 min

From your Writing column. One angle, one post.

Choose your route3 min

Beethoven: write a rough draft first. Mozart: outline hook, point and proof first.

Write three hooks5 min

One that makes the point, one that opens a loop, one wild card. Keep the best.

Write the rest15 min

Deliver what the hook promised

Format and image5 min

Use the suggestion on your card, or one of your own photos

Read it aloud5 min

Cut every line you wouldn’t say to a client

35 minutes. Sezayi and Paul walk around. If someone is stuck on step 3, ask them to tell the client moment out loud and write down the first sentence they say.

Before you go

Post it now, or schedule it for tomorrow morning
Share the link in the Koos Slack channel, so colleagues react early
Dutch or English: pick one for your posts
Your rhythm: how often you post from here
Language and rhythm are personal choices; we agree them per person here (open since 7 October). Early reactions from colleagues help the first posts travel. Next: the ABM tool gets a post roll that shows who posted each week. To ask RJ whether he keeps the team on it.
