What Terra15 does

Terra15 Technologies Pty Ltd is an Australian proprietary limited company founded in 2017 and headquartered in Perth, Western Australia. The company designs and manufactures Distributed Acoustic Sensing (DAS) interrogators — the Treble, Treble+, and TrebleDuo product lines — that convert standard fibre-optic cable into dense arrays of acoustic and vibration sensors for continuous, real-time monitoring over distances up to 40km per fibre (80km combined on the dual-fibre TrebleDuo). Terra15's patented architecture natively measures velocity (rate of change of vibration) rather than strain, which the company describes as a worldwide industry first and positions as providing the lowest instrument noise at microseismic, acoustic, and active seismic frequencies. The hardware is paired with the AssureSrv software platform, which delivers 24/7 managed monitoring, event classification, and remote access for pipeline and infrastructure operators.

Terra15 sells to enterprise and government customers across water utilities, mining, and geoscience, addressing leak detection, pipeline integrity, microseismic monitoring, conveyor roller condition monitoring, and seismic acquisition. Pricing is quote-based with multi-year contracts; the revenue mix combines direct hardware sales to end customers with OEM/embedded supply to channel partners, alongside recurring managed-services revenue via AssureSrv. The company distributes through a combination of direct enterprise sales and strategic channel partnerships — Institute of Mine Seismology (IMS) for mining, MicroSeismic Inc. for North American energy and geoscience, and REMA Tip Top for conveyor monitoring — supplemented by an Open API for OEM integrations.

The business operates with a small, undisclosed headcount led by CEO Dr. Nader Issa, holds ISO 9001 and ISO 14001 certifications, and has received a AUD 1.473 million Investment Attraction Fund grant from the Western Australian government. Named customers and partners include Water Corporation, Woodside, BHP, Anglo American, BRGM, Colorado School of Mines, and Fleet Space Technologies.

Core offering

Terra15 designs, manufactures, and sells Distributed Acoustic Sensing (DAS) interrogator hardware (Treble, Treble+, and TrebleDuo) that convert standard fiber optic cables into dense arrays of acoustic/vibration sensors for real-time monitoring. The company also delivers the AssureSrv cloud-based monitoring and reporting software platform for pipeline leak detection, intrusion detection, microseismic monitoring, conveyor condition monitoring, and seismic acquisition.

Product overview

Terra15 provides Distributed Acoustic Sensing (DAS) interrogators—Treble, Treble+, and TrebleDuo—that convert standard fiber optic cables into dense arrays of acoustic/vibration sensors. The Treble+ offers ultra-low noise for longer-range applications while the Treble provides cost-effective monitoring for shorter ranges and strong-motion scenarios. The TrebleDuo extends capability with dual-fiber simultaneous monitoring for cut-resilience. These hardware products are supported by the AssureSrv software platform, which delivers visualization, event classification, and remote monitoring capabilities. Together, this portfolio addresses water/industrial pipeline monitoring, microseismic monitoring, conveyor systems, and seismic/geophysical applications.

Partnerships

Seven partnerships are on record, tiered core, notable and supporting.

• Institute of Mine Seismology (IMS)coreStrategic or Co-development PartnerTerra15 and IMS formalized their partnership in April 2026, building on more than five years of collaboration. IMS incorporates Terra15's DAS interrogators into its broader seismic monitoring solutions for mining where they provide value alongside conventional seismic sensors. IMS provides turnkey microseismic monitoring solutions including software, processing, interpretation, and monitoring services. The partnership supports mining-related applications including microseismic monitoring, rockburst monitoring, slow-strain monitoring, hydraulic fracture monitoring, tailings dam monitoring, and slope stability assessment. Terra15 supplies DAS interrogators while IMS remains the provider of software, services, and expert interpretation.
• MicroSeismic Inc.coreStrategic or Co-development PartnerTerra15 and MicroSeismic Inc. formed a strategic partnership to introduce Terra15's DAS technology to MicroSeismic customers throughout North America. The partnership covers geoscience and energy sector applications including carbon sequestration, geothermal stimulation, hydraulic fracturing, sinkhole growth monitoring, and critical infrastructure monitoring. MicroSeismic provides turnkey monitoring solutions using Terra15 DAS hardware. The partnership was announced with a joint appearance at IMAGE 2023 in Houston, Texas, featuring both CEOs discussing the collaboration.
• REMA Tip TopcoreStrategic or Co-development PartnerTerra15 and REMA Tip Top partnered to provide the ARMS (Automated Roller Monitoring System) for conveyor systems in mining operations. REMA Tip Top provides end-to-end supply, installation, and commissioning of the ARMS system using Terra15's DAS technology.
