Two ways of thinking. One trail.
Some people arrive with a spark they can't stop thinking about. Others arrive with a stack that has to work by Monday. Marc J. Greenberg builds for both: ideas turned into delivered systems, and a fractional CTO for teams in hospitality, proptech, and payments who need it built.
From spark to something special
Braintrailz turns ideation into delivered systems. Spark: bring the idea rough. Shape: map who it is for, what it must do, what it can skip. Build: the same engineering Marc brings to a CTO seat.
Things that started as a spark: Beyond Limited Thinking, Meet Grey Matters, Trailcraft.
