Engineering the Future
of Mobile Messaging

From SMPP protocol layers to full CPaaS ecosystems, CubeLabs builds the messaging infrastructure that operators, aggregators, and enterprises rely on for mission-critical communication.

Our Approach

Deep Domain.
Custom Built.

At CubeLabs, we don't offer off-the-shelf packages or resell third-party tools. Every engagement begins with understanding your infrastructure, your traffic patterns, and your growth roadmap. Then we build specifically for that.

Our engineers come from telecom and messaging backgrounds, not generic software shops. That means we understand the nuances of SMPP binding behaviour, DLR forwarding, carrier interconnects, and the regulatory landscape across India and globally.

Custom CPaaS
Platform Development

We design and deliver fully bespoke Communications Platform as a Service solutions. Whether you are a mobile network operator wanting to monetize your messaging infrastructure, an aggregator looking to build a white-label platform, or an enterprise needing a private messaging stack, we architect it from scratch for your scale, your compliance needs, and your brand.

Our CPaaS platforms include multi-tenant account management, intelligent message routing, real-time analytics, billing engines, and RESTful API layers, deployable on-premise or cloud.

  • Multi-tenant SaaS architecture with full account isolation
  • Intelligent routing with least-cost and quality-based logic
  • White-label UI and fully brandable API endpoints
  • Billing, invoicing, and prepaid/postpaid credit systems
  • Multi-channel: SMS, RCS, WhatsApp, Voice, OTP
  • Deploy on-premise, AWS, Azure, GCP, or hybrid

Custom Messaging
System Development

Need a purpose-built messaging system rather than a full platform? CubeLabs designs and delivers transactional messaging engines, OTP and 2FA systems, bulk notification platforms, and AI-powered conversational messaging interfaces, precisely scoped to your product's needs.

We work with fintechs, healthcare providers, logistics companies, and e-commerce platforms who need messaging to be reliable, fast, and deeply integrated into their product workflows.

  • OTP / 2FA systems with multi-channel delivery and retry logic
  • Transactional alert and notification engines
  • Bulk messaging with template personalization
  • Chatbot and conversational flow builders
  • Webhook and delivery receipt management
  • DLT-compliant messaging for India

SMPP & Telecom
Protocol Engineering

This is where CubeLabs began, and where our deepest expertise lives. We build SMPP servers, clients, gateways, and proxy systems that operate at the protocol level with the precision telecom environments demand. Our SMPP implementations are production-battle-tested at scale.

  • SMPP v3.4 and v5.0 server and client implementations
  • SMPP proxy and load-balancing gateways
  • SS7 / SIGTRAN signaling interfaces
  • Diameter protocol for 4G/5G messaging
  • HLR / VLR lookup integration
  • Number portability and MNP routing

RCS, WhatsApp &
Rich Messaging

CubeLabs integrates next-generation rich messaging channels into operator and enterprise stacks. We are an Official Google RBM Partner and a registered Meta Tech Provider. We handle the certification, sandbox testing, and production deployment end to end.

  • Google RBM (RCS Business Messaging) integration and campaigns
  • WhatsApp Business API, templates, interactive messages, chatbots
  • Unified channel fallback: RCS → WhatsApp → SMS
  • Rich card, carousel, and suggestion chip development
  • Message analytics and engagement tracking

Compliance &
Security Engineering

Messaging at telecom scale is a heavily regulated space. CubeLabs builds compliance into the platform from day one, not as an afterthought. Our teams have hands-on experience with TRAI DLT regulations, GDPR data pipelines, and the security requirements of enterprise and carrier environments.

  • TRAI DLT integration, entity, sender, and template registration
  • GDPR-ready data handling and retention pipelines
  • End-to-end encryption for messaging channels
  • Audit logging, access control, and role-based permissions
  • Fraud detection and spam filtering modules
  • PCI-DSS aligned billing and payment data handling

How We Work

From Brief to
Production in Weeks

A structured engagement model built for complex infrastructure projects.

Discovery & Scoping

We map your current infrastructure, traffic volumes, compliance requirements, and integration points. Output: a detailed technical scoping document.

Architecture Design

Our senior engineers design the platform architecture, data flows, protocol layers, redundancy, and scaling strategy. Reviewed and signed off before a line of code is written.

Build & Integration

Sprint-based development with weekly demos. We integrate with your existing systems, billing, CRM, network elements, using your preferred protocols and APIs.

Testing & Go-Live

Rigorous load testing, failover simulation, and carrier acceptance testing. We stay on-call through go-live and provide post-deployment monitoring and support.

Technology

Battle-Tested Stack

We choose technology based on fit and scale, not trends.

Backend & Protocol

Node.js, Go, Java for high-throughput SMPP engines. Custom protocol parsers built from specification documents, not wrapper libraries.

Node.jsGoJavaC++
Data & Messaging

Kafka and RabbitMQ for high-volume message queues. Redis for real-time routing tables. PostgreSQL and MongoDB for operational data.

KafkaRedisPostgreSQLMongoDB
Infrastructure

Docker and Kubernetes for containerized deployments. Terraform for infrastructure-as-code. Deployable on any cloud or bare-metal environments.
