PeriodSep 22 – Oct 30
Ideal client: CEOs, founders and PE investors of software and tech companies who need a CFO for a growth, transformation or exit phase.The challenge: The CFO writes about finance in plain words, and finance people love it: CFOs, controllers and accountants are more than half of everyone who reacts. Some posts end with “Need someone in the portfolio? Message me.” Which posts reach the CEOs and investors who sign the mandate?

Who actually reads you, and what the LinkedIn algorithm changed
The CFO posts about four times a week on the CFO job: cash and liquidity, AI in finance, the CFO's role next to the CEO and investors, reporting. 23 posts between 22 September and 30 October 2026, most at 10:00 Berlin time.
The LinkedIn algorithm shows a post to the people who reacted to the last ones, then to people like them. A CFO's feed fills up with other finance people fast: they agree, they react, and they push reach. The CEOs and investors who hire an interim CFO read along, but they are a smaller group. Reach can't tell them apart. Who reacted can.

Finance people are the majority: 631 of 1,200, more than half. 203 of them are CFOs, interim CFOs or finance leaders, often competing for the same mandates. They make the posts travel, and they rarely hire an interim CFO.
The buyers are a smaller group, 114 people, but they are the right ones: founders, Geschäftsführer, CEOs, PE operating partners and investors. The posts that bring them are not the ones with the most reactions.

6 rules for LinkedIn engagement from CEOs, founders and investors
These rules come from what worked on the CFO's own profile, and from the best-performing posts by CFOs and finance creators on LinkedIn over the last 3 months.
1
Lead with cash, not profit. CEOs feel cash on their own account every week. A post that starts with money that hasn't arrived speaks to them; a post about how finance is organised speaks to finance.On this profile: cash and liquidity posts brought 11.2% buyers, reporting and FP&A posts 5.2%.
Don't chase the biggest post. The posts with the most reactions were debates for finance insiders. They grow reach among peers, not among buyers. Judge a post by who reacted.On this profile: the two biggest posts (723 and 457 reactions) brought 6% and 3% buyers. The 10 cash flow mistakes post, with 121, brought 18%.
Tell the founder story behind the CFO. The CFO built and sold a company before becoming a CFO. Founders hire people who have been in their seat: that story belongs in the feed more than twice in 6 weeks.On this profile: personal stories brought 12.5 buyers per post, every other topic 7.7 or less.
Say the uncomfortable sentence out loud. CEOs and investors don't need another explanation of the CFO job. They react to the sentence their own CFO wouldn't dare to say in the board meeting.On this profile: the Claude-can't-replace-a-CFO post brought 13 buyers. Across the niche: Wouter Born's one-line truth about the CFO job drew 4,311 likes.
Use the AI news, then bring it back to the basics. Everyone in finance is talking about AI. The posts that work open with the new tool and end on what has to be in place first: clean data, clear owners, a real cash forecast.On this profile: the “no AI agent yet, clean data first” post brought 15.4% buyers. Across the niche: Tim Vipond's AI-built DCF post drew 2,794 likes.
Give the CEO a list to check this week. A short list of signals a CEO can check on Monday morning turns a finance topic into a management one, and shows how the CFO works in a mandate.Across the niche: Oana Labes' 7 cash flow signals every CEO must track drew 406 likes and 85 comments.
When CEOs and investors read: the best time to post on LinkedIn for interim CFOs
We compared the share of buyers by the day and the hour each post was published. 15 of the 23 posts went out at 10:00 Berlin time and 6 at 8:00, so only those two slots can be compared. There was no Sunday post.

5 posts ready to publish to target CEOs, founders and investors
Each post follows the rules above, written in German in the CFO's voice. Swap in your own details before posting: the real mandate story is what makes it land.

Der größte Auftrag des Jahres hätte das Unternehmen fast in die Liquiditätsklemme gebracht. 📉Ein SaaS-Unternehmen im PE-Portfolio.
Neuer Enterprise-Kunde. Sechsstelliger Jahresvertrag.
Im Board-Deck: der Wachstumsmoment des Quartals.Was nicht im Deck stand:
• Zahlungsziel 90 Tage
• Onboarding-Team vorab aufgestockt
• Implementierungspartner, die sofort bezahlt werdenDer Umsatz stand im Oktober in der P&L.
Das Geld kam im Januar.Dazwischen liefen Gehälter, Tools und Lieferanten weiter.Niemand hatte etwas falsch gemacht.
Der Vertrieb hat verkauft. Finance hat gebucht.
Nur hat niemand gefragt, was der Deal mit dem Konto macht.Seitdem stelle ich vor jedem großen Deal drei Fragen:1. Wann kommt das erste Geld wirklich aufs Konto?
2. Was müssen wir zahlen, bevor es da ist?
3. Reicht der Puffer, wenn der Kunde 30 Tage später zahlt als vereinbart?Ein Deal ist erst dann gut, wenn du ihn finanzieren kannst. 🔥Wer prüft bei euch den Cash-Effekt, bevor der Vertrag unterschrieben wird?

Mein erstes Cashflow-Problem hatte ich als Schüler. Im Kinderzimmer. 👟Ich verkaufte Schuhe im Internet.
Die Bestellungen liefen gut.
Mein Konto nicht.Die Ware musste ich vorher bezahlen.
Das Geld der Kunden kam erst, wenn das Paket angekommen war.
Und jede Retoure kam zurück, nachdem ich längst nachbestellt hatte.Mehr Bestellungen hießen am Anfang: weniger Geld.Damals hatte ich kein Wort dafür.
Heute heißt es Cash Conversion Cycle.Aus Tredex wurde später ein Unternehmen, das ich verkauft habe.
Danach war ich CFO bei Foot Locker.
Heute sitze ich mit CEOs und Investoren am Tisch, die dieselbe Frage haben. Nur mit ein paar Nullen mehr:Warum wächst der Umsatz, aber nicht das Konto?Die Antwort ist fast immer dieselbe wie im Kinderzimmer:
• Wann bezahlst du deine Lieferanten?
• Wann bezahlen dich deine Kunden?
• Wie viel Geld liegt dazwischen im Lager oder in offenen Rechnungen?Das habe ich nicht im Studium gelernt.
Das habe ich gelernt, als ich meine Schuhe nicht mehr vorfinanzieren konnte. 💡Was war euer erstes echtes Cash-Problem?

Ein guter CFO macht sich im Board-Meeting manchmal unbeliebt. Das gehört zum Job. 🎯Der CEO will die Akquisition.
Der Investor will das Wachstum.
Der Vertrieb will den Rabatt.Und der CFO fragt: „Können wir uns das leisten?“Diese Frage ist unbequem.
Aber sie ist billiger als die Antwort sechs Monate später.Ich sehe in PE-backed Unternehmen oft zwei Arten von CFOs:Der eine liefert die Zahlen, die alle sehen wollen.
Der andere liefert die Zahlen, die alle sehen müssen.Der erste ist bequem.
Der zweite schützt den Exit.Ein CFO, der nie widerspricht, ist kein Partner.
Er ist ein sehr teurer Reporting-Service.Mein Anspruch: Aus „Das geht nicht“ wird
„So geht es, und das kostet es.“Wann hat euch ein unbequemes Nein vom CFO zuletzt Geld gespart? 👇

A 13-week cash plan in five minutes, and the three assumptions behind itRule 5: use the AI news, then bring it back to the basics. Modelled on Tim Vipond's “Build me a DCF model” post.

Claude baut dir in fünf Minuten einen 13-Wochen-Cashplan. Und er sieht großartig aus. 🤖Genau das ist das Problem.Ich habe es ausprobiert.
Saubere Tabelle. Formeln. Ein Chart mit dem Liquiditätsverlauf.Dann habe ich die Annahmen geprüft:
• Alle Kunden zahlen pünktlich.
• Umsatz und Zahlungseingang fallen in dieselbe Woche.
• Im ganzen Quartal keine Steuerzahlung.Kein CFO würde das so ins Board-Meeting tragen.
Eine KI schon. Und sie würde es sehr überzeugend erklären.Der Plan sah fertig aus.
Er war es nicht.KI ist schnell.
Aber sie weiß nicht, dass dein größter Kunde immer 20 Tage zu spät zahlt.
Das weiß nur, wer die Debitorenliste kennt.Deshalb gilt für mich:
1. Erst die echten Zahlungsmuster.
2. Dann Annahmen, die jemand verantwortet.
3. Dann KI für Speed und Szenarien.Nicht andersrum. 💡Nutzt ihr KI schon für den Cash-Forecast, oder prüft ihr noch jede Zeile?

Der Umsatz wächst um 30 %. Das Konto nicht. Das ist kein Wachstum. Das ist ein Warnsignal. 🚨Ich sehe das oft in schnell wachsenden Software-Unternehmen.
Die P&L sieht gut aus.
Der Kontostand erzählt eine andere Geschichte.Diese 5 Signale sollte jeder CEO jede Woche sehen:1️⃣ Der Umsatz steigt, der operative Cashflow nicht.
Ihr finanziert Wachstum aus dem Working Capital.2️⃣ Die DSO steigen Monat für Monat.
Kunden zahlen später, und keiner fragt nach.3️⃣ Der Vertrieb verhandelt Zahlungsziele ohne Finance.
Den Effekt sieht die Buchhaltung erst 30 Tage später.4️⃣ Der Forecast plant Rechnungen, nicht Zahlungseingänge.
Dann plant ihr mit Geld, das noch nicht da ist.5️⃣ Der Puffer für Fixkosten schrumpft.
Gehälter warten nicht auf den nächsten Zahlungseingang.Zwei davon gleichzeitig? Dann gehört Cash auf die nächste Board-Agenda. 🔥Ich habe daraus einen 13-Wochen-Cashflow-Check gemacht: eine Seite mit den Fragen, die ich in jedem neuen Mandat zuerst stelle.Kommentiere „CASH“ und ich schicke ihn dir.Welches Signal seht ihr bei euch gerade am häufigsten?

LinkedIn lead generation: lead magnets that work to target CEOs, founders and investors
Reactions show interest. A download shows intent. The fastest way to find out which CEOs and investors are serious is to give them something useful and see who asks for it.
In CFO and finance content, these formats get the most requests:
Format 1The cash flow checklistA list of the questions a CEO or board should ask about cash, offered early in the post.
Format 2The ready-made modelA model that already works (three statements, balance check), sent for a one-word comment.
Format 3The 13-week cash forecastA rolling 13-week cash forecast, with the method or prompts behind it.
Format 4The editable cash plan fileA simple cash plan template people can adapt to their own lines.
Our pick for you: “The 13-week cash flow check”Built from the 10 cash flow mistakes graphic the CFO already shared and the questions from the October 30 post: when the money really comes in, which payments are due, where cash is stuck. One page, 13 weeks, the questions asked first in every new mandate. Offer it in post 5 with “Kommentiere CASH”.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 CEOs and investors to the profile. It doesn't say when to reach out. Most never comment, so they stay invisible, and a founder reading every cash post in October may have hired another interim CFO by January.
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
Post about cash first: money that hasn't arrived, payment terms, the 13-week forecast. Here cash posts brought twice the share of CEOs and investors of reporting posts. Add your own founder story and one uncomfortable opinion a month.
For this CFO, Wednesday brought the highest share of buyers (12.4%) and Saturday the lowest (7.5%). Tuesday brought the most buyers per post. The hour mattered more: 8:00 beat 10:00 by about 1.5x.
About four posts a week brought 114 CEOs, founders and investors in 6 weeks, and 7 of them came back 3 times or more. Keep the rhythm, and give the posts that sell the work the weekday 8:00 slot.
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 23 posts published between 22 September and 30 October 2026 (the first 100 people per post) and sorted the 1,200 people by role. Two posts were left out: a magazine post that tagged the CFO, and a job ad. Comments were not counted, so engagement figures are a floor.
Niche rules come from top posts by CFOs and finance creators over the last 3 months. Role groups are approximate, and some founders sell to the same audience; a Netwarm scan matches people to your own ideal client.
