Turning Reddit into a pipeline generating B2B channel

The CPMs are insanely low. The challenge isn’t cost — it’s knowing who to target, how to speak Reddit, and how to measure real impact.” — Jason Lauritzen, Product Marketing and Growth.

The Challenge

WarpStream saw early promise on Reddit — they started with subreddit targeting and retargeting, and the economics were strong from day one. CPMs were extremely low, and campaigns were ROI positive even with basic setup.

The issue was scale. Subreddits are inherently constrained. WarpStream’s buyers — engineers — don’t just sit in niche subreddits. They browse everything: gaming, memes, random threads.

WarpStream knew there was more reach available, but Reddit’s native targeting couldn’t unlock it. There was no reliable way to say: “Find data engineers wherever they are on Reddit.”

Importing their own contact lists wouldn’t work. Reddit users sign up with personal emails, while WarpStream’s CRM was built on work emails. That made both targeting and exclusion less effective using native tools.

Finally, measurement is definitely challenging with Reddit. Reddit could show engagement and website and in-product conversions, but not whether those users turned into real pipeline. Also, like many SaaS-based infrastructure products, there is often a team of users vetting and then using WarpStream in production, and Reddit doesn’t have company-level attribution.

How WarpStream Uses Reddit to Drive Pipeline

WarpStream’s approach isn’t a single tactic — it’s a system. Three layers working together:

Pillar 1: Expand Beyond Subreddits (Scale the Channel)

WarpStream moved from subreddit targeting → audience-based targeting across all of Reddit using Primer.

Instead of asking: “Which subreddits contain my ICP?” They asked: “Wherever my ICP is — show ads to them.”

They used:

• CRM data (HubSpot) with Primer’s match rate boost (work → personal email translation)
• Primer’s built-in prospecting database to go beyond their known contacts
• Broad Reddit inventory

That shift unlocked meaningfully higher match rates — up to ~70% for their core personas — which made both targeting and exclusions far more precise.

Result: Massive increase in reachable audience

"You’ll see someone comment ‘why is this Kafka ad in a gaming subreddit?’ — and then say they’re actually a data engineer. That’s when you know it’s working.”

Pillar 2: Align Measurement to Reddit’s Strengths (Pipeline Influence, Not Last Click Conversion)

WarpStream explicitly rejected last-click attribution for Reddit. Instead, they built a practical measurement model. Ideally they’d be able to create a single unified record of all company interactions from website visits to form submits at a company level. Jason pieced things together to:

• Track click-level influence → pipeline
• Map activity back to companies via website de-anonymization (through Primer + Factors)
• Evaluate performance on:
  
  • Pipeline created
  • Revenue influenced
  • Directional trends (not perfect attribution)

"If pipeline influenced is greater than what we spend — we keep going. It doesn’t need to be perfect.”

Result: ~74x ROI (click-to-pipeline). Clear justification for continued investment

Pillar 3: Build Native Creative + Iterate Aggressively

WarpStream treats Reddit like Reddit — not like LinkedIn or Google.

They use:

• Freeform posts (look like organic content)
• Lo-fi video (phone-shot, native feel)
• Link posts + educational content

And importantly:

• Comments are ON
• They engage directly in-thread
• Answer product questions in real time

“We don’t force people into a sales funnel. We give them the information right there.”

They also run:

• Continuous creative rotation
• Multiple formats in parallel
• Manual ad group splits (since Reddit lacks native rotation)

Creative is where most of the iteration happens for WarpStream — but they don’t optimize it the way most B2B teams expect.

Because Reddit doesn’t produce a high volume of immediate conversions, they don’t try to pick winners based on downstream metrics like signups or pipeline in real time. That data takes too long to materialize.

Instead, they use a two-layer system.

In the short term, they evaluate performance based on website visits and engagement from high-fit traffic.  Primer and Factors de-anonymize that traffic and validate whether those visitors match their ICP at the company level.

The goal is simple: which ads are getting the right people to the site?

Over time, they connect those same campaigns back to pipeline and revenue, but that feedback loop operates on a longer horizon.

"We optimize short-term on quality visits. Long-term, we look at which of those turn into real pipeline.”

Execution-wise, this requires more manual structure than other platforms.

Reddit doesn’t handle creative rotation well, so WarpStream splits campaigns by format and creative type — separating freeform posts, videos, and link ads into distinct ad groups. This allows them to control spend and compare performance more directly.

They also maintain a steady stream of new creative, rotating formats and styles to avoid fatigue in a relatively small ICP.

The result is a system that balances speed and signal. They can quickly identify what’s driving the right traffic, while still tying performance back to pipeline over time.

Key Principles from WarpStream’s Playbook

The Outcome

WarpStream turned Reddit from an experimental channel into a repeatable pipeline driver.

• Sustained ultra-low CPMs (~$3)
• Scaled reach beyond subreddit constraints
• Achieved clear pipeline attribution with 74x ROAS
• Proved Reddit can drive enterprise deals

"It’s like any ad platform. Know your audience, speak their language, and don’t waste money on the wrong things.”

Run This Play

• Ideal for B2B teams targeting technical or niche ICPs
• Works best when:
  
  • You care about pipeline (not just leads)
  • You’re willing to test creative aggressively
  • You’re thoughtful about copy and creative
