Telecom

We build real-time communication software for telecom vendors and enterprises. Unified communications clients, encrypted messaging apps, and collaboration platforms that handle demanding scale and strict reliability requirements.

What we do

Improve your
existing software

Already have a communication platform that’s falling short? We can extend its functionality, harden its security, or integrate it with other tools and services. For enterprise and institutional clients where reliability and data protection are non-negotiable, we’ll make sure your software meets those demands.


Build custom
software from scratch

We design and build communication software from the ground up — tailored to your protocols, your users, and your scale requirements. Whether it’s a UC client, an encrypted messaging app, a cloud-native communication platform, or a real-time collaboration tool with AI features, we’ll build it to work exactly the way you need it to.

Covering every type of real-time communication product

Carrier grade telecommunication apps

Carrier-grade telecommunication apps

We build UC clients for leading telecom software vendors, working closely with their engineering teams to deliver high-performance, cloud-native apps across every major platform. Our work in this space includes some of the most widely deployed communication clients on the market.

Rich instant messaging apps v2

Rich instant messaging apps

We build encrypted messaging apps with one-to-one and group chat, voice and video calling, and rich push notifications. We work across protocols, from XMPP to RCS, depending on what your product needs. Our work with Ejabberd and XMPP helped Fling users send 50 billion messages.

Social apps

Social apps

Want to build the next Instagram, TikTok, or something entirely new? We design and build the core features social apps depend on: video and audio feeds, real-time interaction, followers, and rich instant messaging.

“Leading telecom software vendors choose us because we’ve repeatedly shown how we achieve excellent usability, seamlessness and cross-device support in modern unified communication applications. ”
Marin Luetic
Head of partnerships

Important features:

  • Voice and video calls and conferencing
  • End-to-end encrypted messaging
  • RCS and XMPP protocol support
  • Cloud-native deployment
  • Multi-device and cross-platform support
  • Whitelabel support

Built a mobile app for 70,000 Royal Caribbean crew across 40 ships →

We built a mobile app that brings crew communication, scheduling, and daily tasks into one place. Using React Native and Java Spring Boot, we designed the app to work reliably even offline, giving crew access to essential tools no matter where the ship is sailing.

Still unsure about something?

Don’t worry, whatever it is, we’ve got you covered in our FAQ.

At DECODE, we build custom software tailored to your business needs, from AI-powered applications to enterprise platforms. This includes:

  • Enterprise platforms – Scalable systems built for complex operations, with AI where it creates real business value.
  • AI-powered products & agents – AI assistants, copilots, workflow automation, and intelligent features integrated into your products and operations.
  • Consumer-facing apps – Web and mobile products designed for usability, engagement, and AI-enhanced experiences.
  • Digital transformation solutions – Modernizing legacy processes with AI, IoT, automation, and smart integrations.
  • Rapid prototyping & MVPs – Turning ideas into launch-ready products quickly, including AI proof of concepts and MVPs.

Every product we build is designed with scalability, maintainability, and long-term growth in mind, ensuring it continues to deliver value as your business grows.

DECODE has been delivering enterprise-grade software since 2012. A few examples include:

Our track record proves we can handle scale, complexity, and long-term partnerships.

We’ve already shipped in most of the specialized areas clients ask about. Some examples:

AI. We launched a complete AI business platform for Decidr, a $50M-funded AI startup, in 5 months. We’ve also built an AI voice assistant with sub-800ms response times and an AI health platform for Supplentia, now used by 100+ practitioners.

Industrial and logistics. We built the real-time reservation system a Class I US railroad now runs on: it processes 400,000+ reservations a day and saves them over $100M.

Telecom. We scaled Metaswitch’s mobile engineering from a small team to 21 engineers delivering production software.

Regulated or sensitive data. For fintech, healthcare, and other regulated industries, we can run AI models locally on Spark, our in-house AI infrastructure, so your data never touches a public API.

If your project sits somewhere we haven’t named here, ask us directly. We’ll tell you straight if it’s a fit.

We work across the full spectrum of software development, from native mobile apps and cross-platform solutions to web applications, backend systems, and complex integrations.

We’re at our best on projects where our senior expertise can make a strategic difference.

  • Enterprise collaboration: We often integrate with large in-house engineering teams to accelerate delivery and bring niche expertise. For example, we partnered with a US $12B company, joining a 200-engineer team with a small team of 10 high-quality experts, solving complex engineering challenges at scale.
  • Greenfield projects: We also work with experienced founders to build products from discovery to launch. In these cases, we guide product strategy, design, and architecture while delivering high-quality, scalable code.

In short: Whether we’re strengthening an enterprise engineering team or building a product from scratch, we focus on projects where our expertise makes the biggest difference.

We start by analyzing your current workflows and identifying what slows your team down down. Then we design and build a custom software solution that simplifies those workflows.

For example, we can automate reporting and approval processes, replace spreadsheets with tailored platforms, or connect separate systems into a single, more efficient setup.

The result is software that fits with your existing tools, reduces manual work, and helps you make faster, data-driven decisions.
