INTRO
Bubbles AI is reshaping how teams collaborate, offering both live and asynchronous meetings powered by artificial intelligence. In a crowded productivity SaaS market, scaling efficiently was critical. The company needed to acquire new customers at scale, lower acquisition costs, and ensure recurring revenue from each sign-up.
That’s where we stepped in.
Challenge
Bubbles AI partnered with us with four clear objectives:
  • Acquire new customers at scale
  • Drive demand generation through paid channels
  • Reduce Customer Acquisition Cost (CAC)
  • Scale ad spend without sacrificing ROI
The challenge lay in balancing aggressive growth with efficiency. Bubbles AI wanted to increase spend and market share — but without bloating acquisition costs or losing customers to funnel leaks.
In short: they needed a growth engine that could scale hard while staying ruthlessly efficient.
Solution
We designed a demand-generation system to win cold traffic, plug funnel gaps, and extend customer lifetime value:
1. Audit & Analysis
  • Conducted a full-funnel audit of paid ads, funnel flows, remarketing, and retention.
  • Identified leaks in audience segmentation, conversion journeys, and remarketing depth.
2. New Customer Acquisition Funnel
  • Built a standalone cold-traffic funnel designed purely to convert first-time customers.
  • Mapped out audiences, created custom and lookalike lists, and rebuilt remarketing sequences.
  • Launched new creative formats, ad variations, and audience tests to accelerate learnings.
3. Conversion Optimization
  • Applied CRO-driven strategies to sales funnels and landing pages to improve conversion rates.
  • Deployed structured A/B tests on messaging, layouts, and CTAs.
4. Retention & Recurring Revenue
  • Integrated email and SMS flows to re-engage users and extend lifetime value.
  • Automated nurture and remarketing campaigns to ensure no lead or customer slipped through the cracks.
5. Scaling Strategy
  • Progressively scaled ad spend while driving CAC down, not up.
  • Used data-driven experiments to double down on high-performing segments and creative.
Results (6 Months)
  • 3,200 new customers acquired with recurring revenue
  • 49% reduction in CAC
  • 5.2x ROAS across paid campaigns
  • Conversion rates significantly improved through CRO strategies
  • Improved traffic quality and higher acquisition rates from cold audiences
  • Ad spend scaled profitably, compounding growth without efficiency loss
