How We Helped a SaaS MVP Cut CAC by 40% in 4 Weeks
When you’re building an MVP, marketing isn’t just about growth — it’s about learning what works without wasting your runway. In this post, we’ll share how we helped an early-stage SaaS founder cut their customer acquisition cost (CAC) by 40% in just four weeks — using lean, data-driven experiments and quick iteration. Even if you’re not ready to scale, this process will help you validate your offer, improve your messaging, and convert smarter.
🧠 The Context
Stage: MVP, pre-revenue
Team: Solo founder, no marketing hire
Goal: 50–100 paying users before raising a seed round
Budget: ~$500/month for paid ads
Product: A simple B2B tool for freelancers (Chrome-based SaaS)
The founder came to us with a working product, a basic landing page, and early traffic — but high CAC and low conversions.
🔍 Week 1: Diagnose & Simplify
We started with a mini audit:
The landing page was long and feature-heavy
Ad copy was generic and didn’t highlight user pain
Tracking setup wasn’t showing cost-per-conversion
What we did:
Rewrote headline + CTA to focus on a specific pain point
Cut landing page copy by 50%, added bullet benefits + clear CTA
Set up Plausible + Meta Pixel for better attribution
💡 Result by end of Week 1: bounce rate dropped by 17%, and time on page increased by 25%.
🎯 Week 2: Segment the Audience
Instead of one generic campaign, we split users into 3 groups:
Freelancers with clients
Solo consultants
Agency owners
Each ad spoke directly to their goals: saving time, looking professional, or scaling processes.
We also added a mini quiz to the site to identify segment fit → and adjusted copy on-page dynamically using a Framer variable.
💡 Result by end of Week 2: clickthrough rate increased 2.1x, and leads began converting at 8% (up from 3%).
🚀 Week 3: Experiment Fast
With $120 in ad spend, we tested:
3 ad headlines
2 landing page variants
1 bonus offer (7-day trial → 14-day + free onboarding call)
We used Google Sheets to log results daily and updated creatives every 3–4 days.
💡 By end of Week 3: CAC dropped from $41 to $26.
🔁 Week 4: Iterate & Scale Smart
The best-performing segment (freelancers with clients) had the lowest CAC and highest LTV potential.
We shut off the other campaigns and doubled the budget on that one segment.
We also added a founder-recorded video on the page → which doubled demo bookings.
💡 Final CAC: $24.50
🎉 Net reduction: 40.2% from the original $41
💡 Key Takeaways
Don’t scale before you segment — talk to one audience at a time
Small tests → fast learnings → real savings
You don’t need a big team or agency to optimize CAC — just focus
Clear copy, fast landing pages, and simple tracking go a long way
