How a Cybersecurity Firm Booked 38 Enterprise Meetings With LinkedIn DMs

By Brendan Ward

One of the most consistent patterns we see at Growtoro is enterprise cybersecurity firms struggling with cold email. The reason is simple: every CISO inbox in the world is a war zone. Every vendor on Earth is pitching them. Cold email reply rates collapse to 1–2% no matter how good the copy is.

So when a Series A cybersecurity firm came to us six months ago looking for a way to break through, we didn't pitch them on more email. We pitched them on LinkedIn DMs as the primary channel — and a content-first sequence that would put them in the conversation before the pitch ever showed up.

This is the campaign that produced 38 booked enterprise meetings, 44% reply rate, and $374K in closed-won revenue from $3,200 in total cost.

The Setup

The client sells a cloud workload protection platform. ACV runs $40K–$120K. Their target buyer is the CISO or VP of Security at companies between 200 and 2,000 employees. Above that ICP, they're outgunned by Wiz and CrowdStrike. Below it, the prospect doesn't have budget. The middle band was the entire game.

Their existing outbound was almost all cold email. Reply rate was sitting at 1.6%. Meeting conversion was worse. They were running out of runway to fix it.

Why LinkedIn DMs Were the Right Channel

Three reasons LinkedIn DMs outperform email for this specific buyer:

1. Inbox saturation is lower. A CISO might get 300 cold emails per week. They get 30 LinkedIn DMs. The denominator is 10x smaller.

2. The platform forces brevity. A cold email can be 200 words. A LinkedIn DM that's 200 words gets ignored. The format compresses pitches into the kind of short, sharp messages that buyers actually read.

3. Profile context exists. When a DM lands, the recipient can immediately see the sender's profile, content, and credibility. This is impossible in email. The trust gap closes faster.

The right buyer + the right channel was the precondition for everything that followed.

The Content-First Strategy

Here's the part most LinkedIn outbound gets wrong. Most senders connect, then immediately pitch. The result is a 1–3% positive reply rate.

We structured the campaign differently. Before any DM was sent, the founder of the cybersecurity firm posted three times per week on LinkedIn for 30 days. Specific, sharp content about cloud security failures, lateral movement detection, and the gap between CSPM and runtime protection.

The content did two things. It built recognition — when the prospect saw a connection request, they'd already seen the founder's posts in their feed. And it gave the DM a hook: the founder could open with "saw you liked my post on lateral movement detection — wanted to follow up."

By the time the DM campaign actually launched, the founder had 1,400 new connections from the target ICP and a pipeline of warm conversations ready to start.

The DM Sequence

The sequence ran 4 messages over 18 days:

Day 1 — Connection request. No note. Just the request. Acceptance rate landed at 53%, way above the typical 25-30% baseline because of the prior content exposure.

Day 3 — Soft opener. No pitch. Reference to a specific signal: a recent compliance announcement, a hire, or a piece of content the prospect engaged with. Closing question: "Curious how you're thinking about [specific topic] in your environment."

Day 8 — Value drop. A short message containing a specific insight or stat relevant to the prospect's environment. "We've been seeing 40% of cloud-native attacks in companies your size start with overprovisioned IAM. Couple of patterns we keep noticing — happy to share if useful."

Day 14 — Direct ask. "Worth a 15-minute call to walk through what we're seeing? If not, no worries — happy to keep the conversation in DMs."

Day 18 — Soft breakup. Single line. "No problem if not the right time — just close the loop here."

Across the campaign, 38% of replies came from message 2, 27% from message 3, 22% from message 4, and 13% from the breakup. Notice that without a 4-message sequence, the campaign would have left more than 60% of its results on the table.

The Numbers

Here's what the campaign produced over 86 days:

  • Connection requests sent: 2,640
  • Connections accepted: 1,398 (53%)
  • DMs sent (across all messages): 4,820
  • Replies: 614 (44% of accepted connections replied to at least one message)
  • Positive responses: 89
  • Booked meetings: 38
  • Closed-won deals: 6
  • Revenue closed: $374,000
  • Total campaign cost: $3,200 (LinkedIn Sales Navigator + automation tooling + content time)

The fully-loaded cost per booked meeting was $84. Cost per closed-won deal was $533. ROI was 117x.

What This Campaign Got Right

Three things made this work that most LinkedIn outbound gets wrong:

1. The founder posted content for 30 days before sending DMs. The DMs were warm, not cold. That single decision moved acceptance and reply rates by 2x or more.

2. The first message wasn't a pitch. It was a question or a reference to a signal. By the time the offer showed up in message 3 or 4, the prospect already knew who the sender was and had context.

3. The sequence had four messages. Not one. Not two. Four. Most LinkedIn DM campaigns end after message one. The data is brutal: you'll lose 60–70% of your conversion that way.

What You Can Steal From This

If you're running outbound into a saturated buyer (CISO, CMO, CFO, CRO, etc.), the playbook is:

  1. Build founder content presence on LinkedIn 30 days before campaign launch
  2. Target a precise ICP — narrow band of company size, industry, geography
  3. Run a 4-message sequence: connect, soft opener, value drop, direct ask, breakup
  4. Reference specific signals in every message — never generic
  5. Measure to closed-won, not to reply rate. Reply rate without conversion is vanity.

The Bottom Line

The companies that win in saturated B2B verticals are not the ones with the loudest cold emails. They're the ones with patient, content-first, multi-message campaigns into the right buyer on the right channel. For this cybersecurity firm, that meant LinkedIn DMs. For yours, it might mean something different — but the principles transfer.
