1. Discover
We understand your product, users and technical challenges.
Engineering for connectivity. Built for production.
Our Story
Consultancy to connectivity specialists.
Koroutine builds the systems behind modern connectivity products.
From carrier integrations and provisioning workflows, to subscriber platforms and commerce, we help operators and product teams ship reliable connectivity products that operate at scale.
Founded in 2017, we began as a software consultancy building dependable systems for teams that were let down by brittle technology and slow delivery.
Today our focus is on telecommunications, delivering the operational platforms, integration layers and custoemr experiences that power connectivity products across Europe, Asia and North America.
What We Build
Integration layers, operational software and commerce built for carriers, MVNOs and connectivity products at production scale.
Carrier & Platform Integration
Carrier APIs, EaaS platforms and provisioning integrations wired for production—not lab demos.
Telco Commerce
Storefronts and checkout tied to eSIM provisioning, from catalogue through to live profile.
Provisioning Platforms
SIM and eSIM orchestration from order to activation, with audit trails and recovery paths.
Branded eSIM Solutions
Ready-made storefront, checkout, provisioning and customer portal for travel or domestic eSIM lines.
Operational Platforms
Dashboards and backend services for queue health, subscriber visibility and day-to-day ops.
EaaS & Entitlements
Entitlement integration on operator networks: authentication, provisioning and lifecycle flows.
What sets us apart?
We integrate and build for production networks, not lab demos.
Small senior teams who already speak provisioning, entitlement servers and carrier APIs. You get pace without the overhead of legacy integrators or a generic dev shop learning telco with your budget.
We stay on the implementation layer through go-live and beyond, so context does not get lost between vendors, internal teams and your roadmap.
2. Design
We design the right solution with architecture built for scale.
3. Build
We build, test and integrate with speed and precision.
4. Operate
We support, evolve and optimise, so you can focus on growth.
We develop cloud systems built for the realities of telecoms production
End-to-end telecoms platforms for connectivity products. Designed for scale and built for production. Our systems handle large volumes of events and traffic, and are designed to scale with your business.
We utilise modern stacks for APIs, events, observability and cloud infrastructure, chosen for telecom workloads and the failure modes carriers actually produce.
Trusted to run in production
We build software that survives real users, real payments and real carrier traffic.
