SendBuffer builds mobile core software for private 4G and 5G networks. We provide a compact, fully integrated solution that runs on standard hardware — no proprietary appliances, no vendor lock-in. Our software is 3GPP-compliant across 4G EPC and 5G SA/NSA, designed for fast on-premises deployment in environments where connectivity is not optional: mining operations, defense installations, ports, energy infrastructure, manufacturing floors. Beyond the product, we do hands-on consulting. Network design and planning, deployment and validation, interoperability testing across radio vendors, and ongoing operational support. We've been doing this work for over 15 years - the company is new, the experience is not. Founded in 2025, based in Vicenza, Italy.
