Background

CONVERTIBLES was founded to help Shopify brands move beyond generic conversion optimization toward true personalization. The agency recognized that most ecommerce stores show the same experience to every visitor - regardless of who they are, where they came from, or what they're looking for. This one-size-fits-all approach leaves significant revenue on the table.

CONVERTIBLES bridges the gap between paid advertising and on-site experience, ensuring that different customer segments receive tailored experiences that match their intent, demographics, and buying psychology. With co-founder Julian's nearly a decade of Shopify development expertise, Clay's 10+ years of advertising experience, proven track record (bootstrapped and exited an ecommerce brand from 0 to $900k/month at 12% EBITDA), and proprietary tools like TestBuddy, CONVERTIBLES delivers personalization programs that compound over time.

Tools & Methods

Methodology

CONVERTIBLES operates on a "Personalize for Profit" philosophy:

  1. Map Segments - Identify profit per visitor by campaign, audience, lifecycle, geo, and device
  2. Personalize Experiences - Use Intelligems to tailor offers, prices, and content to each segment
  3. Test & Scale - Validate winners through rigorous testing, then roll out to segments and feed insights back to ads

Technology Stack

  • Intelligems: Primary platform for A/B testing, personalization, price testing, and profit optimization. CONVERTIBLES is a partner agency following Intelligems' acquisition of the Because personalization platform.
  • TestBuddy: Proprietary visual roadmap tool built by CONVERTIBLES to track, organize, and share testing and personalization programs with clients. Available at testbuddy.dev.
  • Shopify / Shopify Plus: All client work is on the Shopify platform.

Testing Approach

  • Always multi-variation tests (2-4 variations per test)
  • Focus on "needle-moving" components: offers, navigation, collection pages, PDPs, cart
  • Approximately 2-week cycles to statistical significance
  • Profit per visitor as the north star metric, not just conversion rate

Competitive Advantages

Personalization Focus

While most CRO agencies run generic A/B tests (button colors, icon placements), CONVERTIBLES builds and manages multiple personalized experiences simultaneously. Different customers see different stores.

Ads-to-Site Continuity

Co-founder Clay brings 10+ years of advertising expertise and firsthand operator experience (bootstrapped and exited an ecommerce brand to $900k/month). CONVERTIBLES coordinates with client ad teams to ensure landing experiences match campaign messaging and audience targeting - closing the gap most brands ignore.

Proprietary Tooling

TestBuddy, built by Julian (nearly a decade of Shopify development experience), provides visual personalization program management, giving clients real-time visibility into what's live, what's being tested, and how each experience performs.

Intelligems Partnership

As an early partner following Intelligems' acquisition of Because, CONVERTIBLES has deep expertise in the platform's personalization and profit optimization capabilities.
