The short version

  • Each has a real cost: Spire Global Maritime now part of Kpler rather than Spire, and spire.com/maritime redirects into the Kpler site; ZeroNorth zeroNorth reported a net loss of roughly $65m for the 2024 financial year, deepening by around 57 per cent, so a multi-year fleet commitment should include contractual protection on continuity and pricing.
  • They diverge on capability: Spire Global Maritime covers Satellite AIS tracking, ZeroNorth covers Voyage optimisation.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Spire Global Maritime

  • Now part of Kpler rather than Spire, and spire.com/maritime redirects into the Kpler site
  • Pricing is not published
  • Sold as a data feed to be consumed through APIs, Snowflake, NMEA streams or FTP, so it needs engineering work before it is useful

ZeroNorth

  • ZeroNorth reported a net loss of roughly $65m for the 2024 financial year, deepening by around 57 per cent, so a multi-year fleet commitment should include contractual protection on continuity and pricing.
  • The company consolidated operations during 2025, liquidating a Norwegian subsidiary, which is prudent cost control but means local presence and account continuity may not be what was originally sold.
  • Pricing is per vessel and per module, so the headline vessel figure understates the cost of an owner who wants voyage, bunker and emissions capability across a fleet.
  • Recommendation quality depends on the quality of noon reports and vessel data supplied, and an owner with poor reporting discipline will get poor optimisation regardless of the algorithms.
  • It sits between technical performance tools and chartering systems and fully replaces neither, so most owners run it alongside an existing voyage management system and pay for overlapping capability.
