When Growth Stalls
Verde & Co (fictional name) is a sustainable fashion e-commerce founded in 2023. Three people: the founder (design and product), a freelance developer, and a part-time marketing person.
Situation before RUNXT:
- Stable revenue at ~€50K/month
- Conversion rate: 1.2% (industry average: 2.5%)
- Repeat purchase rate: 8%
- Cart abandonment: 78%
- Email marketing: generic newsletters with 15% open rate
The problem wasn't the product (excellent quality, competitive prices). The problem was that they treated all customers the same.
The Transformation: 4 Interconnected AI Systems
System 1: Personalised Recommendations
We implemented a recommendation engine that analyses each visitor's behaviour in real-time:
- Browsing and purchase history
- Products viewed vs. purchased
- Size and style patterns
- Price sensitivity
Result: Conversion rate went from 1.2% to 3.8%. Average order value increased by 23%.
System 2: AI Email Marketing
Goodbye to generic newsletters. Each email is unique:
- Recommended products based on customer profile
- Send timing optimised per user
- AI-generated subject lines with automatic A/B testing
- Personalised cart recovery sequences
Result: Open rate of 42% (previously: 15%). Cart recovery: from 3% to 18%.
System 3: Demand Prediction
A model that predicts what products will sell and when:
- Reduces dead stock by 60%
- Anticipates seasonal trends
- Optimises supplier purchases
- Suggests when to launch sales
Result: Gross margin improved by 8 percentage points. Dead stock reduced from 25% to 10%.
System 4: Intelligent Customer Service
A chatbot that actually helps:
- Recommends sizes based on previous purchases
- Manages returns and exchanges automatically
- Escalates to human only when necessary (12% of cases)
- Available 24/7 in Spanish and English
Result: Customer satisfaction: 4.7/5. Average resolution time: 3 minutes.

The Multiplier Factor: Repeat Purchases
The most impactful data point isn't revenue. It's the repeat purchase rate: from 8% to 31%.
This means almost 1 in 3 customers buys again. And they do because:
- They receive relevant recommendations (not spam)
- The shopping experience is seamless
- Post-sale service is excellent
- They feel understood as a customer
A repeat customer has a €0 acquisition cost and a 40% higher average ticket than a new customer.
Investment and ROI
- Implementation: 8-week project
- Monthly AI cost: ~€400 in APIs and hosting
- Cumulative ROI at 6 months: 26x
With the same 3-person team, Verde & Co generates 3.6x more revenue. The founder spends her time on design and strategy, not putting out operational fires.
Key Lessons
- Personalisation isn't a luxury, it's a necessity. In e-commerce, treating everyone the same is losing money.
- Repeat purchases are the real growth engine. Acquiring a new customer costs 5-7x more than retaining an existing one.
- The data you already have is gold. You don't need more data. You need to use what you have better.
- AI amplifies what already works. If your product is good, AI gets it to those who need it.
