Three characters on the .net in the X-for-Y form. G4T reads as gateway for trade, growth for teams, or grants for technology.
Gateway for trade is the most substantive. Cross-border commerce runs on intermediaries handling customs, payments, compliance, and documentation, and the software serving them is a growing category as trade rules get more complicated rather than less. A short technical-sounding name fits that world.
Growth for teams suits B2B SaaS generally, where the audience reads this kind of shorthand fluently.
The 4-as-for pattern is the useful part. It gives three letters a structure, which is the difference between a domain someone can repeat after hearing it and one they have to write down. That distinction shows up in every referral the business ever gets.
Three characters, fixed supply, no spelling ambiguity, .net.
