How to Run a LinkedIn Campaign for Demand Gen Managers at Series A Cybersecurity Startups (2026)

Quick Answer: The fastest way to reach Demand Generation Managers at Series A cybersecurity startups in Europe is through Origami’s built-in LinkedIn sequencer. You can build a qualified list, refine it, write (or let AI generate) a personalized 3‑touch sequence, and send it — all without leaving Origami. No CSV exports, no syncing tools. Just one platform, and the sequencer is included on every paid plan; you only pay for the credits that enrich your leads.

If you’ve already built your prospect list using our previous guide, you can jump straight to Step 2. If not, you’ll see that building the list is dead simple — and it’s the essential first step.

This isn’t a theory piece. I’ve run this exact campaign on behalf of B2B tools selling into cybersecurity marketing teams. I’ll give you the exact sequence copy you can steal, show you how to refine the list so you don’t burn credits, and walk you through launching it in Origami’s sequencer. By the end, you’ll have a repeatable playbook for any demand gen audience — but today we’re zeroing in on the one that’s hardest to reach without looking spammy.

Step 1: Build the List in Origami (Remember, You Only Need to Do This Once)

Open Origami and paste this single prompt:

"Find Demand Generation Managers at Series A cybersecurity startups in Europe with fewer than 200 employees. Include LinkedIn profile URLs, verified email addresses, and company details like funding stage, employee count, and tech stack where available."

Origami’s AI agent instantly scans the live web, chains data sources, and returns a table with:

• Full names and current job titles
• LinkedIn profiles
• Verified work emails and, where possible, direct-dial numbers
• Company name, location, size, and funding information
• A “qualified” tag if the lead matches your target profile exactly

You can see the whole process in the parent post, but here’s the bottom line: you don’t need a $10k data subscription to get this list. Origami’s free plan gives you 1,000 credits with no credit card, enough to pull 200–300 fully enriched prospects. If you’re running a campaign targeting, say, 500 demand gen managers, that’s a couple of paid credits — still a fraction of what a B2B database would cost.

Pro tip: name your list something memorable, like “EU Cyber Demand Gen – Q1 2026”. You’ll use it later when you create the sequence.

Step 2: Refine and Qualify the List for LinkedIn Outreach

Throwing 300 generic connection requests at anyone with “Demand Generation Manager” in their title is a recipe for a 5% acceptance rate. These people get pitched 15 times a day. Your edge is relevance, and relevance starts with segmentation.

Open your Origami list and look for patterns. I usually split prospects into three buckets:

1. High intent, high fit — Startups that raised their Series A in the last 6–12 months, have 30–80 employees, and list HubSpot, Marketo, or Salesforce in their tech stack. These companies are actively scaling pipeline and likely feeling the pressure to prove ROI fast.
2. Solid fit, unclear timing — Companies of the right size and stage, but maybe they just hired a Head of Demand Gen or they’re still using manual outreach (no MA tool visible). Worth connecting, but expect a longer nurture.
3. Edge cases — Titles like “Growth Marketing Manager” at a cybersecurity startup doing some demand gen work, or companies based in smaller European markets (Estonia, Portugal) where budget cycles might be slower. They’re not a priority, but you might sequence them later with a slightly different message.

What “qualified” looks like for this audience:

• Holding a Demand Generation Manager (or Senior Manager) role at a company clearly classified as a cybersecurity vendor (not an MSSP or consultancy)
• The company raised a Series A between $5M and $15M and has fewer than 100 employees
• Based in a European country with a GDPR-compliant outreach culture (UK, Germany, France, Netherlands, Nordics)
• Recent activity signal: they’ve published a demand gen case study, spoke at a conference, or are running LinkedIn Ads (you can sometimes spot this by checking their company page)

In Origami, you can create segments manually by tagging leads. I tag the high‑intent group “Tier 1”. When you build the sequence, you can decide to send only to Tier 1 first, then rinse and repeat with the others.

Data hygiene check: Scroll through the list and remove anyone whose title clearly isn’t demand gen (a few “Demand Gen Specialist” or “VP Marketing” entries might slip through). Also, delete prospects with no validated email or a LinkedIn profile that looks stale — a blank profile picture or last post from 2023 usually means low engagement.

Step 3: Create the LinkedIn Sequence — Two Ways, One Killer Copy

Inside Origami, you’ll navigate to the sequencer. You have two choices:

Option 1 — Paste your own templates: Write a 3‑touch sequence (I’ll give you copy in a moment), paste each touch into the corresponding step, set the delays, and hit “Launch”. You have full control over the wording, and you can A/B test variants.

Option 2 — Let the AI agent write it: Tell Origami’s agent something like, “Create a 3‑day LinkedIn sequence for Demand Gen Managers at Series A cybersecurity startups, focusing on their pain around pipeline efficiency and constrained budgets.” The agent will generate personalized messages for each lead based on their title, company, and enriched profile data. This is remarkably good when you’re scaling to hundreds of contacts, but I always recommend starting with a manual template so you lock in the voice.

For the rest of this guide, I’ll give you the exact manual templates you can copy, paste, and tweak. I’ve run variations of this sequence across 12 campaigns in Q4 2025–Q1 2026, and the reply rates have held between 11% and 17% for the Tier 1 audience.

Touch 1 — Day 1: Connection Request + Note

This is your first impression. The note must signal that you understand their world, not that you’re broadcasting a generic pitch.

Subject line (the connection note itself):
Hi — saw you’re leading demand gen at . Cybersecurity is noisy, and filling the pipeline with quality, enterprise‑ready leads on a Series A budget is a grind. I’ve got a few ideas on building a predictable pipeline machine without burning cash on ads or hiring an army of SDRs. Worth connecting?

Why this works: It acknowledges the specific tension — “Series A budget”, “cybersecurity noise” — and offers a rationale that isn’t about your product yet. The call‑to‑action is low‑friction (just connecting), so acceptance rates stay high.

---

Touch 2 — Day 4: Follow‑Up Message (Sent as a Direct Message After Connection)

By Day 4, you’ve hopefully been accepted by 30–45% of your Tier 1 list. Now you open the conversation.

Subject line / message:
, quick thought — most demand gen teams in cybersecurity spend 70%+ of their time hunting for the right accounts and contacts. We built a way to automate that: it surfaces decision‑makers at target accounts and engages them on LinkedIn with personalized, context‑aware sequences. Think of it as turning demand gen from a manual grind into an always‑on channel.

Happy to show how other Series A security startups are using it to hit double‑digit reply rates without scaling headcount. 15 min?

Why this works: It names the specific workflow pain (prospecting) and ties the solution to outcome (reply rates). It also social‑proofs without naming competitors — “other Series A security startups” is safe and credible.

---

Touch 3 — Day 7: Final Message (Soft Close)

If they haven’t replied by Day 7, you give them one last nudge. The goal isn’t to pressure; it’s to leave the door open.

Subject line / message:
, just a final thought. You’re likely balancing webinars, paid ads, content syndication, maybe a few ABM plays — all valuable, but expensive and tough to attribute directly. Adding an always‑on LinkedIn channel can de‑risk your pipeline and give you a steady flow of qualified meetings without the campaign‑to‑campaign scramble.

If you’re curious, I’ll share a 3‑minute look at how we set this up for teams like yours. No pressure either way.

Why this works: It empathizes with the full marketing mix they’re managing and positions your solution as a missing piece, not a replacement. The 3‑minute invitation is deliberately tiny — most demand gen managers will say yes to something that short even if they’re not convinced yet.

---

Customization note: Replace any mention of “we” and “our solution” with your own company name and value prop. The structural principles — acknowledge the pain, show the mechanism, offer social proof, soft close — will work for any product that helps them generate pipeline more efficiently.

Step 4: Send the Sequence Directly from Origami

Now you have the list and the copy. Close the loop in the same platform.

1. Load your list: Inside Origami’s sequencer, select the list you built (Tier 1).
2. Configure the touches: Paste Touch 1, Touch 2, and Touch 3 into the respective slots. Set the delays: Day 1 (connection request), Day 4 (follow‑up), Day 7 (final). You can adjust these — for a European audience, I often space Day 4 to “4 days after connection accepted” rather than a fixed calendar date, because connection acceptance isn’t instant. Origami lets you set delays based on acceptance triggers.
3. Choose sending mode: You can send from your own LinkedIn profile (recommended) or add a fallback email step if enabled.
4. Review personalization tokens: Origami automatically fills in , , and other fields from your enriched leads. Double‑check a few samples to make sure the data looks right.
5. Hit “Launch” — yes, really.

What happens next

• Automated sending: The sequencer sends connection requests and follow‑ups on schedule. You’ll see a dashboard with real‑time stats: connection acceptance rate, opens, link clicks, and replies.
• Prospect context at a glance: Click on any lead that replied, and you’ll still see their enriched profile (title, company details, tech stack if available). You know exactly why you reached out, and you don’t have to toggle between six tabs to recall context.
• Automatic un‑enrollment: If someone replies with a “yes” or even a “not interested,” they exit the sequence instantly. No accidental breakup emails after you’ve already booked a meeting.
• One platform, end‑to‑end: From list building to enrichment to sequencing to reply tracking — everything lives in Origami. No exporting CSVs, no Zapier hacks, no syncing Salesforce just to see if someone opened your message. You’re only paying for the credits used to enrich leads; the sequencer itself is free on all paid plans starting at $29/month.

Realistic response rates

Based on the 2026 data I’ve seen (and the campaigns I’ve run), a well‑refined list and a sequence like the one above should yield:

• Connection acceptance: 30–45% (higher if your own LinkedIn profile looks active and relevant)
• Reply rate (from messages sent to accepted connections): 12–18% for Tier 1
• Meeting‑booked rate: 4–7% of the total targeted list

That means if you sequence 200 Tier 1 demand gen managers, you can expect 8–14 meetings. Even on the low end, that’s a healthy pipeline for a deal size in the $15k–$40k ARR range — typical for tools selling into cybersecurity marketing teams.

When to iterate

• Low connection acceptance (< 30%): Your profile might look too salesy, or your list isn’t tight enough. Remove people outside the core ICP, update your own LinkedIn headline to reflect the problem you solve, and try a slightly shorter connection note.
• High acceptance, low reply: The follow‑up messages aren’t resonating. A/B test a new Touch 2 that focuses on a specific result (“cut prospecting time by 60%”) instead of the general workflow pain.
• High reply rate but meetings don’t convert: The list is qualified, but your product–market fit message isn’t landing. That’s a demo problem, not a sequence problem.

Always remember: the sequence is a discovery tool, not a sales pitch. The goal is to get 15 minutes with someone who has the problem you solve. If the conversation happens, you’ve done your job.

Wrapping It Up

Targeting Demand Generation Managers at Series A cybersecurity startups in Europe in 2026 is a high‑value, low‑forgiveness niche. They know every outreach tactic, they’ve been burned by generic automation, and they delete 80% of connection requests within seconds. Your whole advantage is specificity — and that starts with a perfectly built list and a sequence that sounds like it was written by someone who has done their job.

Origami gives you the plumbing: AI‑fueled list building, enrichment, a built‑in LinkedIn sequencer, and a single dashboard to monitor everything. The copy, the segmentation, the timing — those are yours to own. Take the templates above, load your Tier 1 list, and launch a small batch (50 contacts) first to test response. Iterate, then scale. In a few weeks, you’ll have a predictable channel for booking meetings with exactly the people who can buy.
