They back software that saves a whole fleet money. Fuel, port and routing costs all matter a lot here.
They want real shipowners signed as paying clients. A paid pilot with one big fleet is a strong start.
Most enter at the seed stage and follow to Series A. Maritime CVCs tend to join once you start to scale.

Relationships matter most in shipping, and technology will revolutionise shipping. Both arguments are true.
