You're In Business

Tailcall is a legitimate, Venture-backed (Surge/Sequoia) open-source GraphQL infrastructure project with high technical merit (Rust-based, solves N+1 problems). However, the submission itself is extremely low quality, containing nonsensical data (Technologies: 'construction', Traction: 'most people have used my product') and vague claims. While the technology is verified as innovative and useful for developers, the score is heavily penalized by the lack of serious input data and the early-stage nature of the project relative to the calibration scale (1.4k GitHub stars vs. established brands).
