Currently Building

Education Technology Platform

Grawity

Coaching institutes still run on spreadsheets, WhatsApp groups and paper registers. Grawity replaces that with one connected platform — admissions to attendance to fees to results — built multi-tenant from day one, so every institute gets its own isolated workspace.

TypeScript · React · Node.js / Express · MongoDB
