Our Genesis: Reclaiming the Teacher's Most Precious Resource
Founded in Kolkata's historic academic quarter, IBS9 was born out of a pressing educational reality: dedicated educators spend up to 20 hours each examination cycle wrestling with broken word processors, misaligned Bengali Unicode conjuncts, and illegible mathematical equations.
We engineered IBS9 as an all-in-one assessment studio that respects academic autonomy, safeguards teacher intellectual property with PostgreSQL Row-Level Security, and guarantees print-ready, publication-grade examination papers in minutes.
Our Mission
To equip educators, schools, and tutoring institutions with intuitive, enterprise-grade assessment technology that honors regional scripts, preserves pedagogical rigor, and saves hundreds of hours every academic semester.
Our Vision
To become India's most trusted, teacher-centric examination infrastructure—where high-yield questions, flawless LaTeX typography, and airtight assessment security converge effortlessly.
