Ecommerce Marketplace for Telecom that Serves 102M+ Subscribers

A B2B marketplace platform provider, partnered with Euristiq to lead frontend development for one of its major clients: a leading Indonesian telecom operator. Kloudville's backend carried real limitations that a redesign couldn't wait on, so Euristiq built custom solutions to align a new marketplace UI with the existing system.

Overview

Kloudville is a B2B marketplace platform provider that lets telecom operators and other businesses launch and run their own custom online shops. One of its major clients, a leading Indonesian telecom operator, Indosat Ooredoo Hutchison, needed a digital telecom marketplace UI that matched its brand and business requirements — but Kloudville’s backend carried real constraints that a straightforward frontend swap couldn’t work around. Euristiq stepped in to lead frontend development, designing custom solutions that reconciled Indosat’s UX requirements with the backend’s limitations, and has continued supporting and extending the marketplace ever since.

The result: an ecommerce marketplace for telecom that loads 5x faster and serves 102 million subscribers, with Euristiq’s frontend team still shipping features today.

We engaged Euristiq a little over 12 months ago to build a bespoke UI on top of our marketplace platform, whose native UI did not meet the client’s expectations for UX and branding. They have exceeded my expectations throughout the engagement and are, by far, my best delivery centre in terms of on-time performance, quality, application performance, and professionalism.

01. Problem

About the digital marketplace
Euristiq worked on

Indosat’s marketplace ran on Kloudville’s backend, but a straightforward frontend rebuild wasn’t possible — the backend carried real limitations that any new UI had to work around, not just repaint. Euristiq’s job was to design and build a frontend that met Indosat’s business requirements and brand expectations while reconciling those constraints.

Backend limitations

Kloudville’s platform had constraints that ruled out a simple frontend swap — any new UI needed custom solutions to align cleanly with what the backend could and couldn’t do.

Brand and business fit

The frontend needed to match Indosat’s brand and specific business requirements, not just the generic Kloudville marketplace experience.

Scale

Any change had to hold up under the load of a subscriber base in the hundreds of millions, with no room for regressions.

Scope discipline

A discovery phase was run for a broader rewrite of Kloudville’s system, but Euristiq’s committed scope stayed focused on Indosat’s implementation.

METHODOLOGT

We applied our 4D approach

01

Discover

Ran a discovery phase across Kloudville’s broader system and Indosat’s specific backend limitations, to scope exactly what a custom frontend needed to work around.

02

Decide

Kept committed scope focused on Indosat’s implementation, rather than the broader Kloudville rewrite the discovery phase also touched on.

03

Design

Designed custom solutions and UI patterns that aligned Indosat’s brand and business requirements with what the backend could actually support.

04

Develop

Built and shipped the frontend iteratively, and have stayed on for ongoing feature development and support as Indosat’s needs evolve.

02. SOLUTION

Frontend development for an ecommerce marketplace for Telecom — built around backend limitations

Euristiq leads frontend development for Indosat’s digital telecom marketplace, on top of Kloudville’s backend — designing custom solutions where the backend’s constraints would otherwise limit the UX. The engagement covers architecture, implementation, QA, and ongoing feature development, not a one-time handoff, aligned with custom app development best practice.

Front-end architecture and custom solution design

Euristiq architects the frontend from the ground up and designs custom solutions specifically for the backend’s limitations, rather than treating them as someone else’s problem — this integration work is the core of the engagement.

UI implementation for Indosat’s marketplace

Euristiq’s frontend work included a fully functional CRM giving a 360-degree view of customer data, plus the core buy-flow: catalog, cart, payment, confirmation. Later iterations added “My Account” (profiles, addresses, orders, subscriptions, invoices, issue tracking), multi-language support, Google Analytics, bulk product and postpaid ordering, one-click purchases, coupon discounts, and partner codes.

QA and testing at telecom scale

Every frontend release goes through QA and testing before shipping to a live platform serving a subscriber base in the hundreds of millions, where a regression has an outsized cost. This discipline is part of why the improved UX/UI lifted page load speed 5x and overall platform performance 3x without incident.

Technical consulting and ongoing support

Beyond the initial build, Euristiq provides technical consulting and ongoing frontend support and feature development for Indosat’s marketplace, ensuring continued integration with Kloudville’s backend as both systems evolve. This is an active, ongoing engagement rather than a closed project.

03. RESULTS

5x faster, 102M+ subscribers reached

Reach

102M+ subscribers, 4M+ new users

The new frontend reached the operator’s full subscriber base — 102.2 million people — and onboarded 4M+ new users into the redesigned experience, without disrupting Kloudville’s live backend.

Performance

5x faster page loads

Euristiq’s frontend rebuild increased page load speed 5 times over the platform’s previous interface.

Performance

3x platform performance

Overall platform performance received a 3x boost after the frontend and custom-solution work shipped.

Continuity

An ongoing engagement

Euristiq remains Indosat’s frontend partner today, shipping features and fixes as an active engagement rather than a closed project.

FQA

What is a telecom digital marketplace platform?

A telecom digital marketplace platform is software that lets a telecom operator sell, provision, and manage products and services online — covering product catalogs, pricing, partner onboarding, and billing. Kloudville is one provider of this kind of platform, giving telecom and other businesses the backend to run a custom online shop. For a marketplace like Indosat Ooredoo Hutchison’s, the frontend built on top of that backend is what customers actually experience — which is where Euristiq’s work is focused.

How do you build a custom frontend on top of a backend with real limitations?

Start by treating the backend’s limitations as a design input, not an afterthought — map exactly what it can and can’t do before designing the UI. Euristiq’s approach for Indosat Ooredoo Hutchison’s marketplace was to build custom solutions at the integration layer so the frontend could deliver the UX and business logic Indosat needed, even where Kloudville’s backend couldn’t natively support it. That’s a different, often faster, path than waiting on a backend rewrite — which is why a discovery phase for a broader Kloudville rewrite didn’t change Euristiq’s committed scope.

What should you look for in a custom software development vendor for telecom?

Look for a vendor who can design around backend constraints rather than requiring a full backend rewrite before they’ll start — most telecom platforms can’t wait on that. Euristiq leads frontend architecture, custom solution design, UI implementation, QA, and technical consulting for Indosat Ooredoo Hutchison’s marketplace, and has stayed on for ongoing feature development rather than treating it as a one-time delivery. A telecom software development vendor should offer that same continuity, since marketplace requirements keep evolving after launch.

Is ongoing frontend support common after a marketplace platform launches?

Yes — most telecom marketplaces need continuous frontend investment well after initial launch, since business requirements and backend systems both keep evolving. Euristiq’s engagement with Kloudville and Indosat Ooredoo Hutchison started as frontend development for the marketplace UI and has continued as ongoing feature development and technical consulting, still active today. A discovery phase was run at one point to scope a broader rewrite of Kloudville’s backend, but Euristiq’s committed scope has stayed focused on Indosat’s implementation throughout.
