Building the Independence Layer for Global SMS Communications
We built Zuribu to liberate startups, engineering teams, and businesses from exorbitant aggregator markups and telecom red tape by turning Android hardware into high-throughput private GSM gateways.
Why Traditional SMS Infrastructure Is Broken
For years, software developers and growing businesses were trapped with legacy telecom aggregators. Sending a simple transactional OTP, login code, or delivery dispatch alert required endless paperwork, carrier KYC delays, and inflated per-message charges up to 5x-10x the real carrier bundle rates.
During flash sales or high-traffic events, aggregator queues frequently back up, resulting in delayed OTPs, abandoned customer checkouts, and zero visibility into delivery bottlenecks.
The Zuribu Architecture
Direct Carrier ConnectivityZuribu inverts this model completely. By turning standard dual-SIM Android smartphones into high-throughput private GSM workers, you leverage your own carrier SIM bundles directly—sending messages for as little as ৳0.05 per SMS.
With our low-latency WebSocket coordination, automated SIM load-balancing, and 100% self-hosted Docker edition, you retain complete data privacy and unthrottled messaging freedom.
Our Mission
To democratize enterprise-grade cellular telecommunication infrastructure for every developer and business worldwide by removing middlemen, hidden fees, and vendor lock-in.
Our Vision
A world where transactional notifications, two-factor auth codes, and customer alerts operate with zero aggregator markups, instant sub-50ms dispatch speeds, and absolute privacy on your own terms.
The Principles That Drive Our Code
Every line of Zuribu backend and native Android code is crafted around four uncompromising engineering principles.
Developer-First Ergonomics
Clean RESTful JSON APIs, cURL examples, multi-language SDKs, and cryptographic HMAC-SHA256 webhook signatures that make integration effortless.
Hardware-Native Precision
Native Kotlin foreground workers optimized to bypass aggressive Android OEM battery savers, manage dual-SIM radios, and deliver messages instantly.
100% Data Sovereignty
Whether using our cloud coordination tier or our Self-Hosted Docker edition, your customer database, message payloads, and phone records remain private.
Fault-Tolerant Reliability
Smart carrier SIM failover, real-time balance tracking, and persistent offline SQLite queues ensure zero dropped dispatches during network hiccups.
