3-Touch LinkedIn Outreach Sequence for YC Startups Using PostHog [2026 Edition]

3-Touch LinkedIn Outreach Sequence for YC Startups Using PostHog [2026 Edition]

Quick Answer: Want to reach YC-backed startups that rely on PostHog? Use Origami to build a verified list of founders, CTOs, and heads of growth at those companies. Then, run a 3-touch LinkedIn sequence directly inside Origami’s built‑in sequencer – no exporting CSVs, no piecing together tools. The platform finds your prospects, enriches them with emails and phone numbers, and sends the outreach; you only pay for the credits that enrich leads, while the sequencer itself is free on all paid plans (starting at $29/month, free plan gives you 1,000 credits with no credit card).

If you already followed our guide to building a list of YC companies using PostHog, you’ve got a spreadsheet full of promising accounts. Now comes the part that separates booked meetings from ignored invites: the actual LinkedIn outreach. This post will show you exactly how to turn that list into conversations – from refining and segmenting your prospects, to sending a sequence that feels human, all the way to measuring what works.

I’ve run this exact playbook multiple times for companies selling into the YC / PostHog ecosystem. The numbers are real, the templates are copy‑paste ready, and the workflow requires nothing but a browser and an Origami account.

Step 1: Build Your List in Origami (if you haven’t already)

If you’ve already built your list using the parent guide, jump straight to Step 2. If not, here’s the 30‑second version.

Open Origami and type a prompt like this:

"Find Y Combinator companies that use PostHog. Include founders, CTOs, VPs of Engineering, and heads of growth at US‑based startups. Return verified names, email addresses, LinkedIn profiles, and company details."

Origami’s AI agent will search the live web, chain data sources, and return a fully enriched table. You’ll get not just names and titles, but also the tech stack signals (PostHog + other tools they use), location, funding stage, and sometimes even recent hiring intent. The free plan gives you 1,000 credits – enough to pull a few hundred leads without spending a dime – and paid plans start at $29/month.

Now, let’s refine that list so your LinkedIn outreach doesn’t waste a single connection request.

Step 2: Refine and Qualify the List for LinkedIn

A raw list of “YC companies using PostHog” is not a campaign. You need to cut the noise and segment your targets into groups that will receive different messaging.

What “Qualified” Looks Like for This Audience

A qualified lead is a YC startup that:

• Actively uses PostHog as a core analytics tool (confirmed by website tags, job postings, or engineering blogs).
• Is post‑seed or Series A (too early and they won’t have budget; too late and they may have already layered on a modern data stack).
• Has a person in a growth, product, or engineering leadership role who can champion a new tool or consultative solution.

How to Refine Inside Origami

Before you even download the list, use Origami’s filtering and tagging to segment:

1. Role segmentation – Split the list into three buckets:

   • Founders / C-level (usually the highest reply rate if you target pain points like “investor reporting” or “hiring for product analytics”).
   • Heads of Growth / VPs of Product (they care about conversion metrics and user journeys).
   • CTOs / VPs of Engineering (they care about data pipelines, cost, and scale).

2. Company size & funding – Tag companies with fewer than 50 employees and between $500k and $15M in funding. These are the sweet spot for selling tools or services that help them scale beyond basic PostHog usage.

3. Engagement signals – Flag any prospect whose enriched profile shows they’ve recently posted about PostHog, hired for a “data engineer” role, or are using complementary tools like dbt, Snowflake, or RudderStack. Those are buying signals.

4. Remove bad fits – Ditch agencies, consultancies that merely mention PostHog in a blog post, and any contact who isn’t on LinkedIn at all. Your sequence will run via LinkedIn, so the lead must have a profile.

Once you’ve refined the list, you’ll have a clean cohort of 80–150 highly relevant people. That’s more than enough to fill a month of outreach if you’re adding value, not volume.

Step 3: Create Your LinkedIn Outreach Sequence

This is the core of the guide. You have two options inside Origami:

1. Paste your own templates – Write a 3‑touch sequence, set the delays between touches (e.g., Day 1 → Day 3 → Day 7), and hit launch.
2. Let the AI agent write it – Origami’s AI can generate a personalized 3‑day LinkedIn sequence automatically, using each lead’s title, company, and tools so the message feels custom.

I’ll give you a full, copy‑ready template that you can use either way. Every message is tailored to someone at a YC startup who lives inside PostHog. The language references real pain points, not generic “grow your business” fluff.

Day 1 – Connection Request (with a note)

Why this works: You name‑drop PostHog and YC to trigger pattern recognition. You promise value (patterns from other startups) without a pitch.

"Hey , I’m talking to a handful of YC teams using PostHog and noticing a pattern: most start hitting growth ceilings once they pass 10,000 tracked users. I’d love to connect and share what the top 10% do differently. No pitch, just a resource."

Length: ~70 words. Keep it under 300 characters to avoid getting cut off.

Day 2 or 3 – Follow‑Up Message (different angle)

Subject line: your PostHog stack

", quick follow‑up – I analyzed 40 YC companies on PostHog and the ones scaling fastest are layering behavioral cohorts and warehouse‑native analytics on top. Most aren’t moving off PostHog; they’re augmenting. Are you all purely on the event stream, or starting to blend it with your warehouse data?"

Length: ~65 words. The question at the end makes it easy to reply. It also positions you as someone who knows the ecosystem, not a spray‑and‑pray salesperson.

Day 7 – Final Message (soft close)

Subject line: wanted to close the loop

", last note from me – I put together a short Loom walking through how two YC teams (one at Seed, one at Series A) used their PostHog data to drive revenue conversations with investors. It’s 5 minutes, no pitch. If you’re curious, I’m happy to send it over. If not, I’ll assume the timing isn’t right. Either way, thanks for connecting."

Length: ~75 words. This message accomplishes three things: it provides a genuine resource, gives an off‑ramp, and respects their time.

Step 4: Send the Sequence Directly from Origami

This is where Origami stops being a list‑building tool and starts being a full‑cycle outreach machine.

Launching the Campaign

Inside the same dashboard where you built your refined list, click “Create Sequence” and select “LinkedIn.” Choose whether you want to paste the templates above or have the AI agent craft a custom version for each lead (a massive time‑saver when you have 100+ contacts). Set the delays (I recommend 1 day, then 3 days, then 4 days between touches) and click “Launch.”

Origami will automatically:

• Send connection requests from your LinkedIn account (you’ll have authorized it via secure integration).
• Trigger the Day‑3 follow‑up only to those who accepted the request.
• Pause or un‑enroll anyone who replies – no awkward “break‑up” message after a booked meeting.

Tracking and Prospect Context

Every open, click, and reply appears in the same Origami dashboard alongside the lead list you built. While you’re looking at a contact’s activity, you still see their enriched profile (title, company, tools used, full details), so you understand why you reached out. No flipping between a data‑export CSV and a LinkedIn Sales Navigator tab.

This closed‑loop environment lets you iterate fast. If a segment isn’t responding, you can tweak the messaging for the next batch without leaving the platform.

What to Expect for This Audience

With a well‑refined list of YC companies using PostHog, here are realistic 2026 benchmarks:

• Connection acceptance rate: 25–35% when your profile looks credible and you mention “YC + PostHog.”
• Positive reply rate: 8–12% across all three touches. Many replies happen on Day 3 or Day 7, not right after the connection.
• Meeting‑booked rate: 3–5%, assuming you’re selling a tool or service that genuinely helps them scale analytics.

If your reply rate is below 5% after a few weeks, iterate on the copy first. Try a different angle (e.g., focus on investor reporting instead of data scale). If the connection rate is low, revisit the list – your targets may be too senior, or you may need more signal that they’re active PostHog users. Origami’s enrichment sometimes surfaces buying signals you initially missed; use them to re‑rank the list.
