Business Challenge

A Missed Revenue Opportunity at Checkout

For years, a German marketing firm helped e-commerce businesses optimize their checkout experience. But there was one major problem: after a customer completed a purchase, the journey simply ended.

In the current e-commerce environment, every single customer interaction moment presents an opportunity — and the checkout confirmation or “Thank You” page is one of the most underused. The company knew there had to be a better way. They recognized this post-purchase moment as a golden opportunity to connect with customers with tailored personalized offers. However, they faced three critical challenges:



Too Little Attention on Customers After They Buy

Too Little Attention on Customers After They Buy

Even though company already had a lot of traffic from their ecosystem of partners shops, they were still using static Thank You pages that were leaving money on the table.

Why Current Personalization Fails to Scale Effectively

Why Current Personalization Fails to Scale Effectively

Company had a goal to deliver dynamic product offers that are relevant, timely and personalized across dozens of integrations. This was a scaling nightmare especially without sacrificing performance or sacrificing the user experience

Data Is All Over the Place, and Systems Can’t Keep Up

Even though company already had a lot of traffic from their ecosystem of partners shops, they were still using static Thank You pages that were leaving money on the table.

Vision

From Thank You to Next Buy

The company was imagining AI powered engine to plug into any webshop, and the customer context is processes instantly with offered personalized relevant products – directly on the Thank You page. Some might think this is just another ad platform. It’s not. This is a micro storefront tailored which leans on customers recent purchase journey.

Company needed a partner who could not only build this platform, but one who understood the business goal behind it: turning a transactional page into a profit center.
That’s where globlasoft came in.

globalsoft’s Role

Strategic Partner, Not Just a Vendor

From the first day we aligned around business impact, not just features. We became the end-to-end product MVP development team behind this transformation.
With every line of a code, we:

  • Translate business objectives into scalable architecture
  • Shape the user journey
  • Build a sustainable product roadmap for continuous evolution
  • Followed strict compliance standard
  • Deliver a market ready MVP…fast

Solution

A Smart, Scalable Solution: Micro shops as monetization machines

We developed AI-driven micro shop platform that is integrating directly into Thank You pages across companys partners webshops.

What this micro shop does is acting as a real-time intelligence layer between the e-commerce platform and the customer and providing offers based on:

  • Demographics and prefill data (e.g., gender, location, age group)
  • Purchase behaviour and customer tags
  • Inventory availability and product scoring
  • Campaign priorities set by brands and yield managers

Post-Purchase That Pays Off

This platform is now a core revenue stream, expanding across more partner stores and countries each quarter. If you are a webshop and would like to engage customers even after purchase, contact for integration:

It’s been 5 years and we are still counting

This wasn’t a one-time launch. The system is designed for continuous learning and optimization. With every new integration, A/B test, and campaign system is becoming smarter and smarter. In fact, the project is never really “finished” — because that’s the nature of product-led growth. We are extremely proud of our engineers working on this project. They are the blueprint behind the scenes, behind the code.

Team



This Is More Than Just a Project

Working on the Polar project wasn’t just another roadmap task, it was a true experience. We all grew, professionally and personally. What made it meaningful was building for production — every feature, every deployment went live. This responsibility shaped us: we cared more, tested better, thought about users, performance, and uptime. It made us grow. Through it all, we kept the bigger picture in mind, listening to users and focusing on what matters. We became a team that understands what it means when something goes live, and the trust behind every release. Looking back, I’m proud to be part of this story.

Tech Breakdown

Principles and Architecture

  • Domain-Driven Design (DDD) - Modular structure aligned with business logic
  • Hexagonal Architecture - Clean separation of core logic and integrations
  • Event Sourcing - Real-time tracking and replay of user and campaign events
  • Test-Driven Development (TDD) - Ensuring reliability from day one

Used Technologies

  • Backend: Go (Golang), Kubernetes, Google Cloud
  • Frontend: React, Figma (UX prototyping)
  • UX Engines: Panda / Elice for dynamic layout generation

Campaign Logic Engine (Polar System)

  • Store Campaigns - Define how and where stores appear (e.g., device restrictions, campaign overlap)
  • Product Campaigns - Control what gets shown to whom, based on filtering, scoring, and restrictions
  • Tiles & Sorting - Modular blocks that allow for variation in layout, order logic (eCPM, random, user-tag based)
  • A/B Testing - Built into both store and product campaign levels for continuous experimentation




Why it Worked?

We didn’t just build a product. We became part of the client’s team and worked closely with them from the very beginning. Together we planned sprints, made decisions, built and tested features, launched the platform and continued to support and improve it afterward. It was a hands-on collaboration shaped by trust and shared goals.
