How to Run a LinkedIn Outreach Campaign to Spec-Driven Development Companies in the Netherlands & Belgium (2026)

Quick Answer: Origami has a built-in LinkedIn sequencer — so after you’ve built your list of Spec-Driven Development companies in the Netherlands & Belgium, you can refine, sequence, send, and track everything without leaving the platform. No CSV exports, no syncing. You only pay for credits to enrich leads; the sequencer is included on all paid plans, and you can start with 1,000 free credits no credit card.

This is the execution playbook. If you haven’t built your list yet, grab the parent guide on finding those companies first, then come back.

Step 1: Refine & Segment Your Origami List

You’ve already described your ideal customer in plain English inside Origami. The AI returned a list of hundreds of qualified leads with verified LinkedIn profiles, emails, phone numbers, and company details. Now we turn that raw list into an outreach machine.

What “qualified” looks like for this audience

Spec-Driven Development Companies in the Netherlands & Belgium aren’t just any software houses. They’re the firms that live by formal specifications before a single line of code is written — think ASML supply‑chain partners, automotive functional safety teams, medical device manufacturers regulated by IEC 62304, or aerospace suppliers flying around DO‑178C. The people you want are Engineering Managers, R&D Directors, CTOs, and Heads of V&V who care about traceability, model‑checking, and spec‑to‑code drift.

Inside your Origami list, amplify signal by segmenting on:

• Company size: Filter to 50–500 employees. Below 50 they rarely have dedicated spec teams; above 500 you’re often a procurement maze.
• Location: Pin down the hotspots: Eindhoven (Brainport), the Amsterdam‑Utrecht corridor, Delft/Den Haag, Leuven, Antwerp, and the Brussels periphery. Origami returns city‑level data, so you can create segments by metro area.
• Job title: Focus on CTO, VP Engineering, R&D Manager, Head of Verification, or Lead Architect. Skip pure HR or generic IT.
• Technology signals: Origami’s enrichment often picks up tools mentioned on LinkedIn profiles — SPARK, TLA+, Coq, Event‑B, Simulink/Stateflow, DOORS, or even conference tags like FMWeek. Flag those people; they’re your warmest leads.

Remove contacts where the LinkedIn profile is outdated or the company hasn’t posted any spec‑related activity in 2026. A clean 150‑person list beats a messy 500 every time.

Once segmented, you can label each sub‑list inside Origami (e.g., “ASML ecosystem,” “Med‑Device NL,” “Formal‑methods BE”) — that will make the sequencing feel personal later.

Step 2: Create a 3‑Touch LinkedIn Sequence That Feels Like a Human

Origami gives you two ways to build your sequence:

1. Paste your own templates – write your messages, set the delays (Day 1, Day 3, Day 7), and launch.
2. Let the agent write it – ask Origami’s AI to generate a personalized 3‑day LinkedIn sequence for each lead, pulling from their profile data (title, company, industry, tools), so every message is custom.

For a niche like Spec-Driven Development in the Netherlands & Belgium, the human‑written template with slight personalisation still converts best. Below is the exact 3‑touch sequence you can steal, tweak, and drop straight into the sequencer. Use it as a baseline and let the team add a one‑liner per contact.

Touch 1 — Connection Request + Note (Day 1)

No subject line – this note appears directly with the request.

The copy:

Hi [First Name],
I’ve been following the spec‑driven engineering scene in the Netherlands, and your team at [Company] stood out — the work around [mention a specific relevant detail if available, e.g., ASML, ISO 26262] is impressive.

We help engineering leaders reduce the gap between formal specs and implementation, cutting verification cycles by weeks. Would be great to connect and swap ideas on handling traceability at scale. No pitch, just curious what’s working for you.

Word count: ~75. Always drop the sales pitch at this stage. The goal is acceptance, not a demo.

Touch 2 — Follow‑up Message (Day 3, only to those who connected)

Subject (if used as an InMail alternative): Quick thought on spec‑to‑code drift

The copy:

Hi [First Name], thanks for connecting.

One challenge we hear repeatedly from spec‑driven teams: even with rigorous formal specifications, the final code drifts, leading to expensive rework during testing or certification audits.

We built a lightweight approach that automatically checks implementation against your specs, flagging gaps before anything hits the validation bench. I put together a 2‑minute video showing how a Dutch aerospace supplier reduced defects by 60 % — happy to share if you’re interested.

Best,
Alex

Word count: ~85. This opens a door with social proof (“Dutch aerospace supplier”) that feels local and credible.

---

Touch 3 — Soft Close (Day 7)

Subject: One last thought

The copy:

Hi [First Name], just circling back.

If spec‑to‑code traceability isn’t a priority right now, no worries. But if you’re ever curious how we’ve helped spec‑driven teams in Belgium and the Netherlands cut verification time in half, I’d be happy to jump on a 15‑minute call next week.

No rush.
Cheers,
Alex

Word count: ~50. Short, no fluff, no pressure. The phrase “teams in Belgium and the Netherlands” signals you know the landscape and aren’t a generic spammer.

Quick customisation tips

• For the Eindhoven/Brainport segment, mention “ASML supply chain” or “High‑Tech Campus” in Touch 1. Those two frames get disproportionately high acceptance.
• If the contact’s profile mentions a formal language (e.g., Z, TLA+), swap the generic “spec‑to‑code” line with “...checking implementation against your TLA+ specifications...” — the personalisation takes two seconds but lifts reply rates by 8‑12 %.
• For medical device companies, swap the aerospace case study with a Med‑Device example; Origami can generate a variant instantly via the AI assistant.

Step 3: Send and Track the Whole Campaign from Origami

Now the piece that separates Origami from the old way: you never leave the platform. Your list, enrichment data, sequence, and analytics live in one dashboard, so your intent data stays fresh from the moment you search to the moment a reply lands.

Launch the sequence in three clicks

1. Select your segment – pick the refined list (e.g., “Eindhoven‑spec‑dev 50‑500”).
2. Paste your template – or activate the agent‑written variant.
3. Set delays – Day 1 connection, Day 3 follow‑up, Day 7 breakup. Origami lets you choose any cadence; 1‑3‑7 is just a proven baseline.

Hit “Launch,” and the built‑in LinkedIn sequencer starts sending connection requests with notes automatically. When someone accepts, the next touch fires on schedule. If they reply — any reply — they’re immediately un‑enrolled. No accidental “breakup” messages after a booked meeting.

What you see while the campaign runs

• Live activity feed: opens, profile views, replies, connection acceptances — all inside the same dashboard where you built the list.
• Prospect context on hover: while checking a contact’s activity, you still see their enriched profile (title, company, tools used, industry), so you remember exactly why you reached out.
• Automatic un‑enrollment: replies remove the contact from the sequence instantly, moving them to a “Needs Follow‑Up” queue.

What response rates to expect

Depending on how tight your list is, these are realistic ranges for 2026:

• Connection acceptance: 30–45 % for targeted spec‑dev contacts in NL/BE (slightly higher in Eindhoven).
• Reply to Touch 2: 12–20 % if you used the case‑study hook.
• Meeting booked: 3–5 % overall — that’s 3–5 qualified calls per 100 connections.

If after 150 sends you’re below 25 % acceptance, iterate on the list first (bad job titles, wrong company size) before tweaking the message. Acceptance rate is a list‑quality problem, not a copy problem.

Why an integrated sequencer matters (and what the old way costs you)

Traditional stacks still force you to:

• Build a list in one tool
• Export a CSV
• Upload to a separate outreach platform
• Manually sync back replies and enrichments

By the time a contact enters the sequence, their company might have shifted, their role changed, or the email bounced. Origami avoids that decay because enrichment happens at the moment of sequencing, not when you exported. The contact data you see during outreach is the same data the AI used to qualify them.

Competitors that separate list‑building from outreach create a gap where intent data goes stale. With Origami, you’re always working from live signals — and you’re not stitching together three tools just to run a 3‑touch LinkedIn campaign.

The sequencer is included on all paid plans; you only pay for the credits used to enrich your leads. The free plan gives you 1,000 credits (no credit card) so you can run a small campaign today while testing the workflow.
