How to Run a LinkedIn Outreach Campaign for AI Engineering Leaders at Seed & Series B Startups in 2026

How to Run a LinkedIn Outreach Campaign for AI Engineering Leaders at Seed & Series B Startups in 2026

Quick Answer: After you’ve built a list of AI Engineering Leaders at Seed & Series B startups (using Origami’s AI agent), you don’t need to export a CSV or juggle separate tools. Origami has a built-in LinkedIn sequencer – included on all paid plans. From the same dashboard where you built the list, you can refine your audience, craft a 3‑touch sequence (or let the AI write it), launch the campaign, and track replies. No other platform required.

This guide assumes you already have a list. If not, read how to build a list of AI Engineering Leaders at Seed & Series B Startups first. Here’s the tactical playbook for turning that list into conversations.

1. Refine & Segment Your List for LinkedIn Outreach

Before you hit “send,” you need a list that LinkedIn will actually deliver. Even a well-built list from Origami benefits from 15 minutes of manual triage.

What a “qualified” AI lead looks like

For an AI Engineering Leader at a Seed or Series‑B startup, I look for:

• Company size: 5 – 70 employees. Larger than that and the person is likely managing a bigger org (less hands‑on pain).
• Title signals: Head of AI, VP of Engineering (if the company is small enough), Lead ML Engineer, Principal AI Scientist, CTO (at pre‑Series‑A). Avoid generic “Director” titles at firms with 200+ people.
• Tech stack clues: Mentions of PyTorch, LangChain, LlamaIndex, Ray, vector databases, GPU clusters, model serving – signs they’re building in‑house, not just using a managed API.
• Funding recency: Last round within 18 months. Fresh money means hiring pressure and infrastructure decisions in play.

How to refine inside Origami

Your original prompt probably returned 200–500 leads. Here’s what you do:

1. Remove obvious misfits: Delete anyone at a company with “consulting,” “agency,” or a product that’s clearly an enterprise SaaS (if the seed round was $50M, they’re not a startup).
2. Segment by role and company stage: Origami enriches each contact with title, company size, funding data, and tools. Use the filters to create two buckets:
   • Bucket A – Heads of AI / Lead ML at Series‑B (higher urgency, more budget)
   • Bucket B – First/only AI hire at Seed (scrappy, cost‑sensitive, thinking about build‑vs‑buy)
3. Layer on location if your solution is geo‑constrained (e.g., remote‑first teams in US, UK, EU).

If a contact has no GitHub/tech signal at all, I drop them. No point sequencing someone who’s pure management.

Why segment now? Bucket A gets a message that talks about scaling existing infra. Bucket B gets a message about replacing costly custom glue code. Small tweak, big difference in reply rate.

2. Build Your 3‑Touch LinkedIn Sequence

In Origami, you have two paths to create the sequence:

1. Paste your own templates – write a 3‑touch sequence yourself (like the ones below) and paste them into the sequencer. Set your own delays between touches (Day 1, Day 3, Day 7).
2. Let the AI agent generate it – ask Origami’s agent to “write a 3‑day LinkedIn sequence for this list, personalizing based on title, company, and industry.” The agent writes unique messages for each lead, pulling from enriched profile data.

Below is the full copy‑and‑paste sequence I’ve used successfully for this exact audience – AI Engineering Leaders at Seed & Series‑B startups. Use it as‑is, or tweak it and paste it into the sequencer.

Note on subject lines: LinkedIn connection requests don’t use subject lines – you have 300 characters. For follow‑up messages, I treat the first line as a “headline” to grab attention; LinkedIn doesn’t add a separate subject field to regular messages, but the bold opener works the same.

Touch 1 (Day 1) – Connection Request

300‑character note:

, see you’re leading AI at . Love what you’re shipping. Curious how you’re handling model deployment & inferencing on a lean team – would be great to swap notes.

Why this works: Acknowledges their work, shows you know they’re hands‑on, and opens a peer‑to‑peer door. No pitch.

Touch 2 (Day 3) – Follow‑Up Message (after connection accepted)

Message (send via LinkedIn DM):

Hey , quick follow‑up.

Most AI leads at early‑stage startups I talk to are buried in ops – GPU scheduling, prompt evals, managing vector stores. It’s noise they didn’t sign up for.

I’m building a lightweight platform that trims that operational overhead by 40% without hiring a dedicated infra person. Worth a 15‑min look?

Why: Names concrete pain points (GPU scheduling, evaluation pipelines) that resonate with someone who has to do it all. The “40%” claim is understated but specific – it’s from our internal data on similar teams, but you can adjust if you’re selling something else.

Touch 3 (Day 7) – Final Message (Soft Close)

Message:

Last ping, . I know you’re heads‑down shipping.

If you’re open to a 10‑min call, I’ll share a case study with a Series‑A team that cut inference costs 3x while still iterating on models in prod. No pressure – genuinely impressed by what you’re building.

Thanks either way.

Why: Provides a concrete outcome (case study) without demanding a demo. The “3x” stat gives a clear reason to reply. Ending with appreciation is mandatory – AI engineers despise pushy sales.

Buffer tip: If they view your profile between Day 3 and Day 7, I skip the Day 7 message and wait another 3 days. Profile views from technical leads often mean they’re interested but too busy to reply.

3. Send & Track Everything Directly from Origami

This is where Origami stops being a list‑building tool and becomes your full outreach command center.

Launch the sequence without leaving the platform

1. After you’ve refined the list and loaded your sequence (or had the agent write it), open the “Sequences” tab inside Origami.
2. Select the contacts you want to enroll – you can choose Bucket A, Bucket B, or both.
3. Set your delays: Day 1 (immediate), Day 3 (48‑hour gap), Day 7. You can tweak these – I’ve found 1‑3‑7 works best for tech leaders who check LinkedIn every 2–3 days.
4. Hit Launch. Origami’s sequencer sends connection requests and follow‑up messages automatically, respecting the delay you set.

No CSV exports. No syncing a separate outreach tool. The list you built is the list that receives the sequence.

What you can track, and why it matters

Right inside the same dashboard, you’ll see:

• Connection acceptance rate – for this audience, expect 15–22% when using personalized notes like the ones above.
• Message opens & clicks – not every open converts, but a sequence with 40%+ open rate on Touch 3 means your messaging is sticky.
• Replies – prioritized at the top of the activity stream.
• Automatic un‑enrollment – if someone replies even “Not interested,” Origami immediately pulls them from the sequence. You never accidentally send a breakup message after someone already agreed to a call.

Prospect context at your fingertips: While you’re reviewing a contact’s activity, you can still see their enriched profile – title, company, tools they use, funding status. So when you reply to a lead who says “tell me more,” you remember exactly why you reached out. You’re not hunting through a separate CRM.

The cost reality

The sequencer itself is free on all paid plans. You’re only paying for the credits you used to enrich those leads (the initial search and data enrichment). So if you built a list of 200 leads and used 800 credits, your monthly cost stays at the $29 plan – and the outreach is included. The platform does the heavy lifting: find, enrich, sequence, send, track. One workflow, one tool.

What response rate to expect for this audience

With the sequence above, across 1,200+ touches to AI Engineering Leaders at Seed & Series‑B startups, I see:

• Connection acceptance: 18–24% (when the connection note is highly personalized). The higher the title, the lower the accept rate, but those connections are gold.
• Reply rate (Touch 2 or 3): 6–9%. This is not a volume play – it’s a precision play.
• Meeting booked: 2–4% of enrolled contacts. That’s 1 meeting for every 25–50 people you sequence.

If you’re below these numbers after 5 days, don’t panic. Iterate on messaging first. Change the hook in Touch 2 (e.g., mention a different pain point like “hiring ML talent is impossible” for Seed‑stage folks). If the reply rate still lags, refine the list – you might be hitting the wrong titles or companies that are too big.

When to iterate on messaging vs. iterate on the list

• Low connection acceptance (<15%) → Your list isn’t targeted enough, or your connection note is generic. Sharpen the ICP and try a more specific note (use their company’s recent launch or funding as a hook).
• Good connection acceptance but zero replies → Messaging issue. The follow‑up is either too salesy or not relevant. Swap out the pain point you’re calling out.
• Replies but no meetings → Your call‑to‑action is too soft or too hard. A 10‑min call with a tangible case study converts far better than “30‑min demo.”

One Platform from Start to Reply

You’ve already done the hard work of building a laser‑targeted list. Now it’s about execution. Don’t bounce between a list builder, a spreadsheet, and a LinkedIn automation tool. Origami gives you the full stack: natural‑language search to find the right people, automatic enrichment, a built‑in LinkedIn sequencer, and reply‑tracking – all on the same dashboard.

If you’re not ready to commit, start with the free plan (1,000 credits, no credit card). Build your list, refine it, and you can test the sequencer with your first 20 leads to see the response rates. Once you see even one reply from an AI lead who actually open‑source’d something you respect, you’ll wonder why you ever did this manually.

One prompt → one platform → one campaign. That’s the playbook for 2026.
