About Retool Internal-Tools Red
Retool's identity is electric-blue saturation laid over white developer-tool clarity. Founded in 2017 by David Hsu, the platform built the dominant "build internal tools fast" niche for engineering teams.
The brand voice is clean Inter typography, sharp UI-mockup imagery (tables, forms, dashboards, workflow diagrams), and saturated `#3D5AFE` accents. Everything reads as serious developer infrastructure — no whimsy, no decoration, just precision.
