What if changing your segmentation approach could double your conversion rates? Would it be worth trying?

Microsegmentation is what happens when you stop treating prospects like demographics and start treating them like people who are experiencing a specific situation.

Kathleen Booth, former SVP of Marketing and Growth at Pavilion, built a microsegmentation engine that delivered significant improvements in email engagement and conversion rates by identifying those precise moments and speaking directly to them. The system connected intent data, enrichment tools, and orchestration platforms to deliver outreach that felt personal at scale.

The result wasn’t just better metrics. It was bringing in customers (ie, Pavilion members) who stayed longer, contributed more, and made the community stronger. Lower churn. Higher lifetime value. Better fit with every new customer.

Kathleen sat down with us on 🎙 The GTM Science Podcast 🎙 to unpack how Pavilion built their microsegmentation engine, the operational challenges they faced, and where personalization is headed as AI makes everything (too) easy.

In this newsletter, we’re breaking down the operational playbook for implementing microsegmentation at scale, from defining success criteria to knowing when to show restraint.

Start With Who Actually Wins

Here’s what most companies get wrong: they segment before they know who their best customers are.

Pavilion didn’t make that mistake.

Before marketing touched anything, Member Success and Ops ran cohort analysis on existing members. They looked at who stayed, who contributed, who got value. They ran regression analysis on churning customers versus those who renewed. They identified what demographic properties customers with the highest lifetime value shared.

Only then did marketing build segments.

“We wanted to bring in new members, but we didn’t want to just bring in anyone,” Kathleen explains. “We wanted to bring in the people that were the best fit, that would get the most value out of Pavilion, that would give back and contribute and be great members.”

The principle: segment based on who succeeds with your product, not just who will buy it.

Skip this step and you’ll optimize for volume while bringing in customers who churn fast, cost more to support, and dilute everything you’re building.

Find the Moments That Matter

Once Pavilion knew their best members, they asked: when do these people actually need us?

Kathleen calls these “moments that matter.” For Pavillion’s executive prospects, those moments look like:

• Raised a round of funding
• Just got a new job
• Got a promotion
• Lost a job

“These are all the moments when you think, I need a community of peers to help me,” Kathleen says.

But here’s the insight: each moment comes with specific challenges.

Someone who just raised a Series B isn’t dealing with the same pressure as someone preparing for their first board meeting. Traditional segmentation lumps them into “CMO, Series B, SaaS.” Microsegmentation pulls them apart based on what they’re actually facing right now.

So Pavilion built content for those moments. Preparing for a board meeting? Here’s a guide with sample decks and KPI scorecards. First 90 days in a VP role? Here’s your checklist.

The content wasn’t gated. The main guides were all available on the website.

But the practical stuff (the templates, the checklists, the tools) required an email.

And because prospects had already seen the quality of the content, conversion rates on those downloads went way up.

“Every time I’ve ungated something, the conversions, the number of people that still request it and give us their email to get a PDF of it is so much higher,” Kathleen says. “Because they’re able to see the content is good and high quality.”

Build the Engine

Once Pavilion knew who to target and when, they needed infrastructure to personalize at scale.

Josh Carter, now VP of RevOps, built a system connecting multiple platforms. The workflow started with website de-anonymization tooling to identify visitors. Once someone was identified, they were added to a Clay table. Clay enriched them automatically (L&D budget, ICP, company size, location) then scored the lead and determined how to customize outreach.

Copy AI, trained on Pavilion’s voice and company information, generated personalized messaging. The systems talked to each other, pulling from Clay’s data to create contextually tailored emails.

Clay also referenced Pavilion’s existing member list, overlaid with location, role, company size, and NPS scores. For every prospect, the system could say: “Here are one or two or three people who look just like you, who are already happy members.”

All automatic. The emails integrated with their email sending platform and sales outreach platform, teeing up personalized messages for the sales team.

This required tight collaboration. Member Success provided criteria. RevOps built infrastructure using tools like Make.com and Zapier to connect everything. Product Marketing crafted messaging. Content created assets.

“It definitely is a huge team activity,” Kathleen says.

The critical piece? Someone has to own the vision. At Pavilion, that was Josh. He saw how tools could connect and drove the build.

Without that champion, microsegmentation stays theoretical.

The Creepy Line

With enough data, Pavilion could reference almost anything.

Clay could scrape websites to find a prospect’s ICP. Pull job postings to identify L&D budgets and tell prospects exactly how much they had. Parse press releases for funding plans. Track LinkedIn announcements, career moves, etc.

But just because you can doesn’t mean you should.

“I think the most surprising thing, honestly, was how much was possible,” Kathleen says. “You kind of have to rein yourself in and decide what you’re not going to personalize around because you can do so much, you can get so specific. I think it can get creepy if you go too far.”

The rule: Focus on what prospects care about right now. The pain they’re feeling. The goals they’re trying to hit. The challenges specific to their role and stage.

Everything else is noise. Or worse, invasive.

Most teams confuse data availability with data relevance. Having a data point doesn’t mean it belongs in your outreach.

The line between helpful and creepy isn’t about what you know. It’s about what you do with it.

Reference someone’s promotion because it changes their priorities? Helpful.

Reference it to prove you did research? Creepy.

Test Small, Learn Fast

Microsegmentation targets smaller populations. That’s a feature, not a bug.

“If your test doesn’t work, you’re not emailing or reaching out to thousands of people,” Kathleen explains. “It might be 10, it might be 50, it might be a hundred. The cost of a miss is much lower.”

Pavilion would form a hypothesis, customize messaging, and send to small groups. Then look at open rates, click-throughs, and meeting requests.

The goal wasn’t just seeing what worked. It was understanding why.

They tested different motivators for joining: cost and discounts, knowing respected peers were members, upcoming local events.

When mentioning well-known peers drove results with CMOs, they rolled that approach to CROs and Chief Customer Officers.

“You test, you iterate, you see what works, and then you try and roll out those lessons learned to other populations,” Kathleen says.

The Results

The microsegmentation engine delivered material improvements across the funnel.

Open rates went up. Conversion rates increased significantly. Response rates climbed.

“We saw significant improvements in conversion rates,” Kathleen says. “The exact number differs by campaign, but material impacts. A great example was telling them that they had L&D budget, because all of a sudden you’re telling people that they don’t have to spend their own money. That’s pretty powerful. And our response rate went way up for those.”

But the real win wasn’t the numbers.

It was bringing in the right members. People who stayed. Contributed. Made the community stronger.

Lower churn. Higher lifetime value. Better product with every new customer.

This is what matters for revenue leaders. Volume metrics look good in reviews, but converting the wrong prospects creates downstream problems. Longer sales cycles. Higher discounts. More implementation issues. Lower expansion. Faster churn.

Pavilion optimized for contribution and community health, not just member count.

The microsegmentation engine didn’t just improve top-of-funnel metrics. It improved the quality of the entire funnel.

What This Means for You

If you’re a CRO: Microsegmentation delivers conversion quality, not just conversion rates. Work with RevOps and Marketing to define “best customer” based on retention and expansion data. Then build infrastructure to target them systematically.

If you’re a CMO: You can’t build effective segments without Customer Success data. Start there. Who stays? Who expands? Who advocates? Then identify the moments that matter—when your ideal customers actually need you.

If you’re in RevOps: You’re the architect. Champion the vision, not just for how tools connect but the results in GTM you are driving. Own the process and technical build. Enforce the data quality that makes personalization possible.

The question isn’t whether you should implement microsegmentation.

It’s whether you’re going to do it with the operational rigor needed to prove ROI.

Are you segmenting based on who succeeds with your product? Are you identifying the moments they need you? Are you personalizing your outreach to speak to their specific situation?

If not, you’re leaving conversion rates and conversion quality on the table.
