Quick Answer: Use Origami — now with a built‑in LinkedIn sequencer — to find, enrich, and message YC startups that use PostHog, all from one platform. Build a list of qualified prospects, choose a pre‑written sequence (or let Origami’s AI agent write one for you), and launch multi‑touch LinkedIn campaigns that land meetings. Here’s exactly how to do it in 2026.

You already know that Y Combinator startups are some of the hungriest, fastest‑moving companies out there. Throw PostHog into the mix — the open‑source product analytics tool they love — and you have an audience that’s data‑savvy, growth‑obsessed, and scaling like crazy. But cold emailing these teams? A black hole. LinkedIn is where they live, where they network, and where they actually read messages from people who understand their stack.

This guide is the companion to our post on how to build a list of YC Startups Using PostHog. Once you have that list — or if you’re building one right now — this is the playbook for turning it into conversations, demos, and pipeline. We’ll walk through refining your leads, writing three LinkedIn touches that sound like a peer, and sending the campaign directly from Origami’s sequencer without ever opening another tool.

Step 1: Build the List in Origami (or Skip if You Already Have It)

If you haven’t built your list yet, or you want to expand it, here’s the prompt that consistently finds YC‑backed startups actively using PostHog:

“Find YC‑backed SaaS startups that use PostHog, have 10‑200 employees, and list a Head of Growth, CTO, or Data Lead. Focus on companies based in the US, with a preference for Series A or B. Include evidence of PostHog usage like blog mentions, job posts, or GitHub repos.”

Paste that into Origami and within minutes you’ll get a table with:

First and last names
Verifiable email addresses
LinkedIn profile URLs
Current job title, company, and HQ location
Company size, funding stage, and YC batch
PostHog usage signals (when available)
Phone numbers (for multi‑channel follow‑up)

You can do this on the free plan — 1,000 credits, no credit card required. That’s enough to research around 100–150 leads and test the waters. If you’ve already followed the parent guide and have your list ready, jump straight to Step 2.

Step 2: Refine and Qualify Your List for LinkedIn

A raw list from any tool still needs human judgment. You’re not blasting 500 strangers; you’re starting conversations with 20–50 hyper‑relevant people. Here’s how I qualify a list of YC + PostHog leads:

Check for Active PostHog Usage

Origami’s enrichment flags companies that mention PostHog, but I still scan a few signals manually for my top prospects:

Do they have a public PostHog dashboard or shared link?
Is PostHog listed on their tech stack page (BuiltWith or SimilarTech confirmation)?
Have they published a blog post about “how we use PostHog” or “open‑source product analytics”?
Do they have open‑source contributions to PostHog’s GitHub?

If a company only has a generic “PostHog” tag and nothing else, I deprioritize them. The best replies come from people whose company is a heavy, active user.

Segment by Role and Buying Power

The person you message depends on what you’re selling. For most products that complement or extend PostHog (like an activation platform, CRM integration, or analytics services), you want these segments:

Head of Growth / VP Growth – They own the metrics PostHog exposes, and they’re desperate to tie analytics to revenue moves. This is my primary audience.
CTO / VPE – They decided to adopt PostHog and care about scalability, data pipeline, and engineering cost. Reach them if your offering touches infrastructure or developer workflow.
Data Lead / Analytics Engineer – Sometimes a dedicated role in larger Series B teams. They’re the power users who can champion a tool internally.
Founder (CEO) – Only target if the company is under 30 people. Above that, PostHog decisions are delegated.

Segment your spreadsheet into columns for each persona. Later, you’ll adjust the angle of your LinkedIn messages based on the group.

Remove Bad Fits Immediately

Delete anyone who:

Hasn’t changed roles in 9+ months at a startup that isn’t growing (could be stalled)
Shows a title like “VP of Sales” — unless your tool is explicitly for sales teams using PostHog data
Works at a company that is bootstrapped (many YC companies take funding; if they haven’t raised a round in 3+ years, they might not be in a buying mindset)

You’re left with a tight list of 20–60 highly qualified people. This list is the foundation of a campaign that feels personal, not spammy.

Step 3: Create the LinkedIn Sequence for YC Startups Using PostHog

Now for the core of this guide: the actual messages you’ll send. Origami gives you two ways to craft your sequence, both inside the same platform.

Option A: Paste Your Own Templates

You write a 3‑touch sequence yourself, paste the message templates into Origami’s sequencer, and set the delays (Day 1, Day 3, Day 7 — I’ll explain the exact copy below). This gives you full creative control.

Option B: Let the AI Agent Write It

Alternatively, you can ask Origami’s AI agent to generate a personalized sequence for every single lead. The agent reads each contact’s enriched profile (title, company, industry, PostHog signals) and writes connection notes and follow‑ups that feel custom. You can still review and tweak before launching, but the heavy lifting is done.

I’ll share a proven 3‑touch template below. You can use it as-is for Option A, or let the agent riff on it for Option B.

The 3‑Touch LinkedIn Sequence for YC Startups Using PostHog

Cadence:

Day 1: Connection request with personalized note (max 300 characters)
Day 3: Follow‑up message (sent directly; no need to be connected — Origami sequences handle this if they haven’t accepted yet via InMail-style delivery)
Day 7: Final message (soft close)

Audience pain points we’re addressing:

PostHog spits out a ton of data, but teams struggle to turn it into retargeting campaigns, sales triggers, or churn interventions.
YC startups are under pressure to show sustainable growth; they fear optimizing the wrong metrics.
Many self‑host PostHog; integration with CRM, email, and customer success tools is a recurring headache.
As they scale, they start looking at PostHog’s Cloud tier or want to layer on a middleware — they’re open to adjacent solutions.

Day 1 — Connection Request Note

“, noticed is using PostHog (YC ) and scaling fast. I help growth teams at YC startups turn PostHog’s analytics into actual pipeline — not just dashboards. Open to connecting?”

This note establishes shared context (YC, PostHog) and hints at a practical benefit. It’s 270 characters, easily within LinkedIn’s limit.

Day 3 — Follow‑up Message

“Hey — quick observation.

I keep hearing from YC growth leads that PostHog gives them amazing insights, but the data rarely makes it into the CRM or outbound tools. One team I worked with (also YC, also PostHog) connected their events to their sales workflow and saw a 22% lift in upsells in under 45 days.

Thought I’d share if you’re banging your head against the same wall — happy to show you how they did it.

No rush.”

This message is 96 words, direct, and references a familiar pain. It ends with a low‑pressure invitation.

Day 7 — Final Message

“, last note from me on this.

PostHog is great for PLG, but the real wins come when you can push data into the hands of your sales and CS teams at the right moment. I’ve built a playbook specifically for YC startups that want to close this loop without heavy engineering.

If you’d find 15 minutes valuable, let me know. If not, I’ll let you get back to scaling. Either way, rooting for .”

This is 89 words. It’s a soft close that respects their time and reinforces the core value.

You can copy‑paste these messages directly into Origami’s sequencer. Use the personalization tags , , and `` (Origami populates these for you). If you’re using Option B, the AI agent will write variations that might mention specific tools in their stack alongside PostHog, their latest blog post, or a job opening for a “PostHog expert” — all signals that make the message eerily personal.

Step 4: Send the Sequence Directly from Origami

This is where Origami’s built‑in sequencer changes the game. You don’t export a CSV, you don’t hop over to a LinkedIn automation tool, and you don’t manually track who replied. Everything happens in one interface.

Select your qualified leads from the enriched list you built in Step 1 or refined in Step 2.
Choose your sequence. If you used the templates above, paste them into the campaign builder. If you let the agent write them, you’ll see a summary of what it generated for each contact.
Set delays. I recommend Day 1 / Day 3 / Day 7. Origami’s sequencer handles weekends and time zones.
Hit “Launch.”

From that moment, you can watch the campaign unfold in the same dashboard where you built the list:

Send tracking: See which connection requests were sent, accepted, and ignored.
Message analytics: Opens, clicks on any links, replies — all logged against the contact.
Prospect context: While reviewing a contact’s activity, you still see their full enriched profile (title, company, tech stack, PostHog signals). So you never forget why you reached out in the first place.
Automatic un‑enrollment: If someone replies — even a simple “Not interested” — they exit the sequence instantly. Zero risk of accidentally sending a follow‑up after they’ve already booked a meeting. That’s the kind of polish you need when selling to YC founders who get 100+ LinkedIn messages a week.

Pricing note: The sequencer is included on all paid plans (starting at $29/month). You only pay for credits to enrich leads, not for sending. So once you’ve built a clean list, the actual outreach costs you nothing extra.

What Results to Expect

For a well‑targeted list of YC startups using PostHog, here are realistic benchmarks for a 3‑touch LinkedIn campaign in 2026:

Connection acceptance rate: 25–35%
Reply rate (across all touches): 15–22%
Meeting booked rate: 7–10%

These numbers assume your sequence is relevant, you’ve segmented by persona, and you’re reaching out to people who are actively using PostHog. If your reply rate falls below 10%, change the messaging angle — try focusing more on a specific integration pain or a recent milestone in their YC batch. If connection acceptance is below 20%, your list probably needs refining (too many founders or too broad a role set).

When to iterate on messaging vs. iterate on the list:

Low connection acceptance but high reply rate once connected → your messaging works, but you’re targeting the wrong roles or companies. Circle back to Step 2.
High acceptance but low reply → your opening note is good, but the follow‑ups aren’t resonating. Swap in a different pain point or social proof in Step 3.
Low on both → go back to Step 1 and check whether the companies are truly active PostHog users. A list built on weak signals won’t perform no matter how good the copy is.
