Category Standard

JABU (YC S21) is a legitimate, high-traction Series A company transforming the B2B supply chain in Southern Africa. The project has raised over $15M (Tiger Global, YC) and serves thousands of merchants. However, the submission itself was of extremely poor quality (fake email, false 'everyone' reach claims, no data), which heavily penalized the Response Quality score. External verification confirmed the project's high utility and traction, allowing for a high final score despite the submission's deficiencies.
