SuccorfishM2M

What SuccorfishM2M does

SuccorfishM2M (legal entity: Succorfish Limited) is a UK-based private company founded in 2008 in North Shields, Tyne & Wear, that designs, manufactures and integrates hardware, software, and connectivity solutions for subsea and remote marine asset monitoring. Its technology stack centres on the proprietary Delphis underwater acoustic modem line (standard unit and OEM variant) for subsea wireless communication, the SC2 Gen 3 hybrid Iridium satellite and LTE Cat 1 BIS cellular edge gateway with STM32-based edge computing, Bluetooth-enabled GIGO fishing activity beacons, and the MyGearTag acoustic location device for ghost gear recovery. These hardware products are delivered with an in-house cloud SaaS platform and bespoke software development services, with a RESTful API architecture and iOS/Android mobile applications enabling remote electronic monitoring (REM) and operational dashboards for end users.

The company serves a multi-vertical customer base: commercial fishing fleets (lobster, abalone, scallop and general fisheries), defence and special operations, offshore energy operators (oil & gas and offshore wind), marine conservation organisations, ROV/AUV manufacturers requiring OEM acoustic modules, and universities and research institutes. Operations span the UK, North America (Canada), Oceania (Australia) and Europe (e.g., Spain), with deployed hardware proven in more than 20 countries and Delphis modems in use at 20+ universities globally. Notable enterprise deployments include Canadian Atlantic lobster fisheries, Australian abalone divers, and pan-European NETTAG+ ghost-gear trials on Newcastle University's Research Vessel Princess Royal.

Succorfish monetises through a hybrid model: one-time hardware sales (acoustic modems, SC2 gateways, GIGO beacons, MyGearTag), recurring annual airtime/connectivity fees for satellite and cellular services, SaaS subscriptions for fisheries data platforms, and bespoke software development services. All pricing is quote-based with no published list prices; go-to-market is sales-led and event-driven (e.g., UDT London 2026), supplemented by direct sales, research/university partnerships and mobile self-serve apps. The company holds ISO 9001, 14001, and 27001 certifications and is MMO Type-Approved for UK iVMS, which materially de-risks enterprise and government procurement.

Core offering

Succorfish engineers and manufactures underwater acoustic modems (Delphis, Delphis OEM), hybrid satellite/cellular IoT gateways (SC2 Gen 3), fishing gear monitoring beacons (GIGO), covert acoustic communication systems (SC4X), and ghost gear location devices (MyGearTag), integrated with cloud-based SaaS data platforms and mobile applications for Remote Electronic Monitoring (REM). The technology enables subsea communication, vessel monitoring, fishing gear tracking, and regulatory compliance in marine, defence, offshore energy, and research environments where conventional wireless signals cannot operate.

Product overview

SuccorfishM2M offers an integrated subsea communication and monitoring technology ecosystem. The core portfolio centres on three hardware pillars: (1) Delphis underwater acoustic modems — including the standard unit and OEM variant — for underwater data transfer, positioning, and mesh networking; (2) SC2 Gen 3 hybrid satellite/cellular edge gateway providing global asset connectivity and vessel monitoring; and (3) GIGO beacons for fishing gear monitoring. These integrate through a cloud-based REM (Remote Electronic Monitoring) platform and in-house developed mobile/SaaS applications. Ancillary products include the Covert Underwater Communication SC4X for defence, MyGearTag for ghost gear recovery, and dedicated software development services for custom firmware, mobile apps, and enterprise integrations. The architecture connects seabed assets via acoustic modems to surface gateways and satellite/cellular networks, delivering data to cloud platforms and mobile interfaces.
