The Challenge
Streamline HQ had cracked the code on generating leads. Their Google and Meta ads were bringing in 800+ leads monthly at a reasonable $34 cost per lead.
The problem? Only 2% of those leads ever became customers.
The funnel had a gaping hole:
- Sales team overwhelmed with unqualified leads
- Most leads weren't ready to buy—they were researching
- No system to nurture leads over their 45-day average buying cycle
- Ad spend was essentially subsidizing competitor research
At a customer acquisition cost of $1,700, their unit economics barely worked. Scaling ads just meant scaling losses.
Their CEO faced a choice: cut ad spend and accept slower growth, or find a way to convert more of the leads already in the pipeline.
Why They Chose Us
Streamline had tried basic email drips. They'd even hired a "marketing automation specialist" who set up a few workflows. But results were marginal—conversion rate bumped from 2% to 2.4%.
When we showed them how Meta & Google Ads integrated with Business Automation could transform their funnel, they saw the bigger picture.
"Most agencies optimize ads OR optimize nurture," we explained. "We do both simultaneously—and we connect them so each improves the other."
The key insight: ads shouldn't just generate leads. Ads should generate leads AND inform how those leads are nurtured. Nurture shouldn't just send emails. Nurture should send signals back to improve ad targeting.
The Solution
We built a closed-loop system where ads and automation work together.
Intelligent Lead Capture
First, we restructured their ad strategy:
- Multiple conversion points: Not just "request demo" but also guide downloads, webinars, and free tools
- Progressive profiling: Each interaction gathered more data for personalization
- Intent signals: Different offers for different stages of awareness
The Nurture Architecture
Segmentation Engine: Leads automatically sorted into tracks based on:
- Entry point (which ad, which offer)
- Company size and industry
- Engagement behavior (opens, clicks, page visits)
- Explicit responses (quiz answers, preferences)
Track 1: Hot Leads (Demo Requests)
- Instant booking link via SMS and email
- If no booking in 4 hours, personal video from sales rep
- If no booking in 24 hours, case study relevant to their industry
Track 2: Warm Leads (Content Downloads)
- Value-first email sequence: 5 emails over 14 days
- Product mentions only after delivering 3x value
- Behavioral triggers to accelerate if engagement high
Track 3: Cold Leads (Webinar/Newsletter)
- Long-term nurture: weekly value content
- Re-engagement campaigns after 30, 60, 90 days
- Upgrade triggers when behavior indicates readiness
The Feedback Loop
Ad Optimization from Nurture Data:
- Leads who converted fed back as conversion signals
- High-LTV customer profiles used for lookalike audiences
- Content engagement data informed ad creative testing
- Disqualified leads created exclusion audiences
Real-Time Adjustments:
- Ad spend shifted toward campaigns producing nurtured conversions
- Messaging aligned between ads and email sequences
- Landing pages updated based on nurture sequence performance
The Transformation
The results showed the power of integration.
Funnel Metrics Transformation
| Metric | Before | After | Change |
|---|---|---|---|
| Leads/Month | 800 | 720 | -10% (intentional) |
| Lead-to-Customer | 2% | 6.4% | +220% |
| Customers/Month | 16 | 46 | +188% |
| CAC | $1,700 | $935 | -45% |
The Math That Matters
Before:
- 800 leads × $34 CPL = $27,200 ad spend
- 16 customers = $1,700 CAC
After:
- 720 leads × $36 CPL = $25,920 ad spend
- 46 customers = $564 CAC (from ads alone)
- Plus nurture costs: $371 → $935 effective CAC
Annual Impact:
- Previous: 192 customers/year at $1,700 CAC = $326K acquisition cost
- Now: 552 customers/year at $935 CAC = $516K acquisition cost
- Net result: 3x more customers for just 58% more spend
But here's the real kicker: those nurtured customers had 34% higher lifetime value because they were educated about the product before they bought.
The Compound Effect
- Sales productivity up 150%: Reps only talked to qualified, educated leads
- Demo show rate up 67%: Nurture built commitment before the call
- Time to close down 40%: Objections handled in nurture content
- Churn rate down 23%: Better-educated buyers = better fit
The Expansion
With the core system working, we expanded:
- Expansion revenue automation triggering upgrade campaigns based on usage
- Referral sequences turning happy customers into advocates
- Win-back workflows for churned customers and lost deals
- Event-based nurture aligned with industry conferences and seasons
The ads-automation integration became their unfair advantage—competitors spending more on ads but converting fewer leads.
"We used to think of leads as a numbers game—more leads, more customers. Now we think of leads as relationships. The automation builds those relationships at scale, and our CAC is less than half of our competitors'. That's a moat you can't easily replicate."
— David Park, CEO, Streamline HQ
