About TestBox

TestBox delivers live product demos and proof-of-concept environments for B2B software companies. Rather than clones, simulations, or overlays, the platform spins up real, functioning instances of customer software to showcase actual capabilities during sales cycles. The company serves mid-market and enterprise buyers across multiple categories. Current operations span three core areas: a foundational backend platform built in Python and Go, frontend tooling in React/Vue/Svelte, and sales/implementation processes to support customer onboarding and deployment.
