How to Run a LinkedIn Outreach Campaign to Software Startups That Just Raised Seed or Series A (2026)

Quick Answer: To run a high-converting LinkedIn campaign targeting software startups that raised Seed or Series A in the last 24 hours, use Origami — which has a built-in LinkedIn sequencer — to refine your list, deploy a 3-touch sequence with personalized funding-specific copy, and send it directly from the same platform you used to build the list. No CSV exports, no third-party tools.

In the companion guide, you learned how to use Origami to instantly build a hyper-targeted list of software startups that announced a Seed or Series A raise in the last 24 hours. If you haven't read it yet, go do that now — you'll need a live list before you can launch the outreach campaign I'm about to walk you through.

This post assumes you already have that prospect list sitting inside Origami. You've already used a prompt like:

"Find software startups that raised a Seed or Series A round in the past 24 hours. Include the company name, the founder's name and title, email, phone, LinkedIn profile URL, company website, location, funding amount, and funding round type."

Origami returned a clean, enriched list of 50–200 companies with verified contact data for the founders (often the CEO or CTO). All of it is visible in one dashboard. Now it's time to turn that list into conversations.

I've run outreach campaigns like this dozens of times for B2B products and services — selling to freshly funded startups is one of the highest-leverage plays in outbound. When a startup just got funded, they are in deployment mode. They're hiring. They're buying tools. They're making vendor decisions they'll stick with for the next 12–24 months. If you can reach a founder or key decision-maker within the first 48 hours, with a message that acknowledges their new reality, your reply rates will be 2–3x what you'd see with a cold list.

But this only works if you execute the outreach correctly. Let's walk through each step.

Step 1 — Build the List in Origami (Already Done)

You've already built your list. If you haven't, I'll quickly recap what that looks like in Origami.

The prompt above goes into Origami's AI agent. It searches the live web, scrapes funding announcements from Crunchbase, TechCrunch, venture capital firm portfolio updates, and press releases, then chains data sources to pull LinkedIn profiles, verified email addresses (work and personal), phone numbers, and company details. In about 90 seconds, you get a table of contacts that looks like this:

• Company name: "NovaML"
• Founder name: "Samantha Price"
• Title: "CEO & Co-Founder"
• Email: "sam@novaml.ai"
• Phone: +1-415-...
• LinkedIn URL: linkedin.com/in/samprice
• Company size: 7 employees
• Location: San Francisco, CA
• Funding amount: $2.1M
• Round type: Seed
• Industry tags: "machine learning, developer tools"

Everything you need to personalize an outreach sequence is right there. And you got it without touching a spreadsheet or a data vendor.

If you're on Origami's free plan, you can do this with 1,000 credits — no credit card required. That's enough to enrich about 50 leads and send a LinkedIn sequence to them. On paid plans (starting at $29/month), the LinkedIn sequencer is included; you only pay for the credits you use to enrich leads.

Step 2 — Refine and Qualify the List for LinkedIn Outreach

A raw list of all Seed and Series A funded software startups from the last 24 hours is valuable, but not every company on it will be a good fit for your solution. You need to look at the data and cut the ones that won't convert. This is also the moment where you segment the remaining prospects so you can tailor your outreach.

How to Review and Remove Bad Fits

In Origami's list view, you can sort by any column. Start with these checks:

1. Company size and location
If you only sell to US-based companies with at least 5 employees, filter out any startup with fewer than 5 employees or based outside the US. A solo founder who just raised $500k might not have the budget or team to act on your offer yet.

2. Funding amount and round type
A $500k pre-seed round is very different from a $3M seed round or a $10M Series A. I typically remove anything under $750k unless I'm targeting very early-stage. The higher the round, the more urgency there is to deploy capital. A Series A startup likely already has a VP of Engineering or a Head of Sales — those are the people you'll want to reach, not just the founder. For Series A, consider pulling in additional contacts (Origami can enrich other decision-makers at those companies if you ask it to).

3. Industry fit
Scan the industry tags. If you only work with SaaS companies, drop any hardware or biotech startup. If you serve developer-tool startups, keep those and remove fintechs with no DE focus. This is a manual review, but it takes 5 minutes for a list of 50–100 companies.

4. Contact completeness
Make sure the founder's email is verified and the LinkedIn profile URL is present. If an email is missing or the LinkedIn link is broken, you can either delete that lead or ask Origami to try an alternative source. With the sequencer, you need a working LinkedIn profile to send connection requests.

What “Qualified” Looks Like for Newly Funded Software Startups

For my own outreach (I sell a B2B SaaS platform), a qualified lead from this list looks like:

• Pre-seed, Seed, or Series A within 24 hours (freshness matters — after 48 hours, the founder is already flooded with pitches)
• Software or SaaS company (not hardware, not services)
• At least 3 employees (they have a team, which means they'll need collaboration tools, hiring, etc.)
• Founder/CEO or C-level contact available (they are the decision-maker for new tools in an early-stage startup)
• Funding amount > $500k (they have actual budget to spend)
• Email verified, LinkedIn profile present

Once I've filtered, I'm left with a focused list of 30–50 prospects. That's plenty for a single sequence. I don't blast 200 people; I want to personalize and manage replies.

Segmenting for Better Messaging

Before you write your sequence, split your refined list into a few segments. I look at:

• Seed vs. Series A: Seed founders are still hands-on in product and might respond to messages about speed, cost, or MVP acceleration. Series A leaders are suddenly thinking about scale, hiring, and process. Different pain points.
• Round size (small vs. large): A founder who just raised $750k has a different state of mind than one who raised $8M. The latter may already have a procurement process, so your message should anticipate multiple stakeholders.
• Geography: If I have a list of US-based, EU-based, and APAC startups, I'll send different sequences at different times (time zones matter for LinkedIn acceptance).

You can manually tag or group these leads inside Origami's list. Even if you only have one segment, it's helpful to note the characteristics so your sequence copy speaks to them.

Step 3 — Create the LinkedIn Sequence

This is the core of the entire campaign. The messaging has to speak directly to a founder who just got funding. You have exactly one chance to sound like someone who understands their current state.

In Origami, you have two options to set up the sequence:

Option 1: Paste Your Own Templates
Write a 3-touch sequence yourself (connection request note, Follow-Up 1, Follow-Up 2). Paste each message into Origami's sequencer builder, set the delays (I recommend Day 1 request, Day 3 first follow-up, Day 7 final touch), and launch. This is what I do when I want full control over copy.

Option 2: Let the Agent Write It
Once your leads are enriched, you can ask Origami's AI agent to generate a personalized 3-day LinkedIn sequence for all your leads automatically. The agent uses each lead's title, company, industry, and funding data to write a unique variation of the message for every contact. It's not a simple mail-merge; it adapts the copy to the context. After it's generated, you can review and tweak before sending. This is a huge time-saver when you're running multiple campaigns.

For the purpose of this guide, I'll give you my exact templates that you can paste and use today. These have been battle-tested on freshly funded startup founders and consistently get a 35%+ connection acceptance rate and a reply rate north of 12% when the list is clean.

The 3-Touch LinkedIn Sequence for Software Startups That Just Raised Funding

This sequence assumes you're sending to the founder/CEO. If you're targeting a CTO, VP of Sales, or other role, adjust the angle slightly.

Touch 1: Connection Request + Note (Day 1)

Subject/note (300 characters max on LinkedIn):

Congrats on the [Round Type] round, [First Name]. Quick question about your [relevant area, e.g., engineering scaling] plans — would love to connect.

That's it. Keep it short. You reference their exact funding round (use the data Origami gave you: Seed, Series A, etc.) and hint at a problem you solve. Don't pitch. Don't ask for a call. Just open the door.

To personalize at scale, I build a small prompt in Origami's variable field: pull the round type from the enrichment column, and First Name from the contact. Origami's sequencer supports dynamic fields, so I can write the template once and it auto-fills.

Example real message:

Congrats on the Seed round, Samantha. Quick question about your ML infrastructure plans — would love to connect.

Touch 2: Follow-Up Message (Day 3) — Different Angle

Subject line: none (it's a follow-up in the existing message thread)

Body:

Hi [First Name], reaching back out because I saw you just closed your [Round Type] raise. When I worked with a [similar startup, if possible, otherwise: “other seed-stage CTOs building in your space”], their biggest bottleneck right after funding wasn't code — it was [pain point].

If you're neck-deep in hiring or scaling [relevant function], I put together a short resource on [how you help, without naming your product]. Happy to share it — no strings.

Let me know if it's worth a quick DM.

This message does three things: It re-anchors in their funding event, adds social proof (“other seed-stage CTOs”), and offers value instead of asking for something. Replace the pain point with something your solution addresses.

Example (for a developer productivity tool):

Hi Samantha, reaching back out because I saw you just closed your Seed raise. When I worked with other seed-stage CTOs building ML products, their biggest bottleneck right after funding wasn't code — it was onboarding new engineers fast enough to meet the new roadmap.

If you're neck-deep in hiring and ramping the team, I put together a guide on shortening time-to-commit for early-stage engineering teams. Happy to DM it — no strings.

Let me know if it's worth a quick DM.

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

Subject line: none

Body:

[First Name], one last ping. I know you're probably slammed, but I wanted to leave this with you — I help software startups that just raised [Round Type] solve [specific outcome] without [undesirable tradeoff].

No outreach automation, no generic pitch. Ping me if you want to see how it works. If not, I'll leave you to it — congrats again on the round.

Cheers, [Your Name]

This is the “chaser” that makes it easy for them to respond if they've been silently interested. It's polite, acknowledges their busyness, and gives a clear next step.

For a Series A CTO, I'd adjust the outcome: e.g., “cut your cloud cost per engineer by 30% while doubling deployment frequency.”

Each message is 50–100 words. They are direct, free of jargon, and don't sound like a marketing copywriter wrote them. They sound like a person who has been in the trenches with startups.

If you're using Option 2 (AI agent in Origami), you can still take these templates as a baseline and let the agent personalize each touch individually. The agent might pull in a detail like the startup's location or recently posted job listing to make the message hyper-relevant.

---

Step 4 — Send the Sequence Directly from Origami

Here's where most tools fail. You build a list, export a CSV, upload it to a LinkedIn automation tool (which often breaks or gets flagged), and then track replies in a separate place. Origami removes all of that.

Launch the Sequencer Without Leaving the Platform

After you've built and refined your list, click into the Origami lead table, select the leads you want to sequence, and choose “Create LinkedIn Sequence.” Paste your three messages (or use the agent-generated ones), set the delay between touches (I use Day 1, Day 3, Day 7), and hit Launch.

The sequencer handles everything from within Origami's interface:

• It sends connection requests with your personalized note from your LinkedIn account (you'll connect your LinkedIn once).
• It checks if a connection is accepted before sending touch 2. If not accepted, it doesn't send.
• It sends follow-up messages automatically, respecting the delay you set.
• If a prospect replies at any point, they are automatically un-enrolled from the rest of the sequence. No more embarrassing “Hey, just following up, here's my pitch” after they already said yes.
• You see opens, clicks, and replies in the same dashboard where you built the list.

Tracking and Context

While a contact is in the sequence, you can click on their name and see their enriched profile — title, company, tools they use, funding round, number of employees. So when you get a reply notification, you instantly have all the context you need to write a great response. No toggling between tabs.

You can also monitor sequence-wide metrics: connection acceptance rate, reply rate, bounce rate. I watch these daily and tweak subject lines or follow-ups if something isn't working.

What to Expect for Response Rates

On a tightly filtered list of 30–50 software founders who announced funding in the last 24 hours, here's what I typically see with a sequence like this:

• Connection acceptance rate: 35–45% (industry average for cold outreach is around 20%, but the funding trigger and personalized note pushes it higher)
• Reply rate (positive, neutral, or interested): 10–15% of accepted connections, sometimes up to 20% if the segment is very well aligned
• Meeting booked rate: 4–8% of original leads

These numbers assume you're using a human-like tone, not a hard-sell pitch. If your product or service is directly relevant to the “scaling” pain point (e.g., hiring, cloud infrastructure, sales automation, compliance), you'll be on the higher end.

No tool can guarantee these numbers, but Origami's sequencer gives you the mechanics to run it properly without spam triggers.

When to Iterate on Messaging vs. Iterate on the List

If after 10 days your connection acceptance is below 25%, the problem is likely your initial connection note. Test a different hook — maybe refer to the specific investor, or a pain point you know these startups face.

If acceptance is high but replies are low, your follow-up messages aren't resonating. Try swapping the value offer in touch 2 to something more immediate, like a competitive benchmark or a tactical playbook.

If the list itself is off (no one is accepting), go back to Step 2 and tighten your qualification. Maybe you're reaching companies that raised rounds too small to have spending authority, or you're targeting CEOs who don't use LinkedIn. Qualifying harder is always the first move.
