PAiCore Technologies

What PAiCore Technologies does

PAiCore Technologies (legally PAIC EUROPA, S.L.) is a Spanish private limited company founded in 2024 and headquartered in Barcelona, with operations spanning 12+ countries across 5 continents. The company commercializes an open source telecom signaling portfolio inherited from the Mobicents (2003) and Restcomm (2011) projects, offering multi-protocol platforms covering SS7/SIGTRAN, Diameter, SMPP, HTTP, and SIP for messaging, location services, and network interworking across 2G through 5G environments. Its product portfolio is organized into three verticals: Messaging (SMSC, IP-SM-GW, USSD Gw & USSI, SMS Firewall, SMSF, RCS Application Server), Signaling & Geolocation (Network API Gateway, GMLC & CAMARA LBS, Diameter Routing Agent, SEPP, CAMEL Gateway, jSS7-STP, jDiameter), and Business Solutions (ECS Lite, eSIM/IoT, FIX Gateway, Core Network Analyzer, Telephony Application Server, SDP, jSLEE).

The technology stack is built on Java-based open source implementations, with every product released as a free Basic version on GitHub alongside commercial editions. The SMSC platform supports over 100,000 TPS throughput, and the Network API Gateway has been validated at 4,500 TPS. AI capability is delivered through a partnership with TelecomsXChange's OpenTextShield for the SMS Firewall, providing real-time spam, phishing, and spoofing detection across 100+ languages.

PAiCore monetizes through a freemium-to-subscription model: free open source Basic versions drive community adoption, while commercial revenue comes from Technical Support Plans (€1,020 to €4,160 per month across Basic/Standard/Premium tiers), software licensing for SMSC CT, IP-SM-GW, GMLC, DRA and other platforms, and Professional Services bundled into support plans or sold hourly. Go-to-market combines enterprise field sales targeting MNOs, MVNOs, aggregators, VAS providers, and system integrators with community-led growth through GitHub repositories. Distribution relies on direct enterprise sales with 12-18 month minimum commitments, complemented by self-serve open source downloads. Strategic partnerships include GSMA membership, CAMARA Project compliance, and integrations with Comfone and TelecomsXChange.

Scale indicators5 records

Recent moves7 records

Expansion highlights6 records

Emerging players

• Kamailio: Kamailio is a leading open source SIP server widely deployed in VoIP and IMS contexts. It competes with PAiCore's TAS and IP-SM-GW, particularly in open source operator deployments, and shares the OSS community-led approach.
• OpenSIPS: OpenSIPS is an open source SIP server with overlapping signaling capabilities to PAiCore's jSS7 and IP-SM-GW. It is a community-driven alternative targeting smaller operators and integrators, representing the open source competitive set.

Direct peers

• Mavenir: Mavenir is a US-based network software provider offering cloud-native messaging, voice, and signaling infrastructure for MNOs and MVNOs — directly competing with PAiCore's SMSC, IP-SM-GW, and 5G core offerings. Both target the same operator segment with software-led alternatives to traditional vendors.
• Telestax: Telestax is the original steward of the Restcomm open source project from which PAiCore derives its heritage. It provides CPaaS and telecom application server solutions built on JAIN SLEE and the same signaling stack, making it the closest historical and technical peer.
• Mobileum: Mobileum provides signaling, roaming, and security solutions for telecom operators, including SS7/Diameter firewalls and analytics. Its SMS Firewall and signaling security products overlap directly with PAiCore's SMS Firewall and Core Network Analyzer.
• Radisys: Radisys (now part of Tucson) provides open telecom platforms including media servers, SIP stacks, and 5G SBA components. Its Connect Open Broadband and 5G solutions compete directly with PAiCore's application server and signaling product lines.
• Atrinet: Atrinet is a telecom network solutions vendor specializing in signaling, VoLTE, and 5G core deployments. Its offerings overlap with PAiCore's IMS, SIP, and signaling products, primarily serving Tier-2 and Tier-3 operators.

Others

• Nokia: Nokia's Network Infrastructure group provides messaging, signaling, and 5G core products that compete with PAiCore's portfolio. As a Tier-1 incumbent, it represents the large-vendor status quo that PAiCore's open source value proposition targets.

Broad incumbents

• Ericsson: Ericsson is the dominant incumbent vendor for telecom core networks, including SMSC, MSC, and 5G core products. PAiCore's open source messaging and signaling solutions are positioned as alternatives to Ericsson network functions.
• Metaswitch: Metaswitch (now part of Microsoft Azure Operator Nexus) provides virtualized IMS, SBC, and messaging solutions to MNOs globally. It shares PAiCore's signaling and messaging focus but operates as a much larger incumbent with broader product portfolio.
