  • Starboard Maritime Intelligence

    Participated · Series A · Sep 2025

    Starboard Maritime Intelligence is a New Zealand startup focused on maritime security. Its platform analyzes over a billion maritime data points daily — including ship tracking, satellite imagery, radar, oceanographic data and autonomous sensors — to detect suspicious activity and issue real-time alerts. The platform is already used by governments, defense agencies and commercial operators in over 30 countries. The company plans to expand its presence in North America, Europe and the Indo-Pacific region. Starboard raised A$20.7 million in a Series A to support that global expansion and further develop its technology. CEO Trent Fulcher says the platform protects maritime borders, infrastructure and commercial supply chains, and the financing will help set the standard for real-time maritime intelligence. Jonty Kelt (King River Capital) and Vu Tran (OIF Ventures) will join the company’s board. Starboard Maritime Intelligence is a Wellington, New Zealand–based SaaS startup founded in 2019 that applies machine learning to maritime data to detect suspicious vessel activity. Its software platform combines AIS, satellite imagery and scientific models to enable maritime activity monitoring and analysis. The company supports governments, border security authorities, NGOs and fisheries inspectors in prioritizing which vessels to focus on and inspect. In April 2024 Starboard raised A$4.6M (NZ$5M) in seed funding. The proceeds will be used to strengthen support for a growing number of analysts in the Pacific region and to expand the company’s go-to-market function into other countries and industry verticals. No operating metrics (revenue/users) were disclosed in the article.
