The classroom is the sanctum

India's most exam-hardened coaching network has an edtech arm that refuses the sector's playbook: 100,000 paid learners and no free-user theatre, doubt-solving that runs past 1 am because that is when students actually study. Ujjwal Singh's charge is that a decade of edtech changed everything except the learner's life — a video-conferencing tool was never a classroom.

The 'secret sauce' Singh says you can't get in a nutshell — hence the months spent interviewing its teachers, principals and toppers before writing a line of product.
The brief

The argument in sixty seconds

Singh's claim is that Indian edtech has been decorating the periphery while the sanctum stays untouched: as in a temple, the actual thing happens where the deity meets the person praying — in education, where a teacher meets a learner — and after a decade of apps and unicorns the learner's life has barely changed. Infinity Learn, incubated out of Sri Chaitanya's 36 years of coaching — a network Singh says accounts for roughly 10,000 of the 42,000 students across the IITs and more than a quarter of top medical-college seats — began with two and a half months of pure listening to teachers, principals, IIT toppers and strugglers. What they heard: a video-conferencing tool bolted onto a class is not teaching, engagement scores are abysmal, and testing cannot be relaxed. The product became a 4A loop — assessment, a batch with guided learning, self-learning material, and doubt support that peaks between 10 pm and 1 am, because the learners are nocturnal. The company runs against the sector's grain: 100,000 paid learners, a Zerodha-style insistence on revenue with growth, acquisitions (Teacherr, Don't Memorise) only where integration is easy, and Amazon Academy as partner and competitor at once. The stakes are the 230 million K-12 students Vishal opens with, parents still asking 'what did the teacher teach' instead of 'what did you learn today' — and an industry that finally attracts IIT and IIM talent but has not yet answered whether the child at the centre is learning at all.

Takeaways

Ideas to carry out of this hour

01

A video call bolted onto a class is not teaching

Teachers who could maneuver a physical class of 40 found themselves stuck inside video-conferencing tools never built for the activity-question-video choreography of a real lesson. Engagement scores were — and Singh says still are — very low for mass classrooms, to the point where parents discovered children who hadn't attended two years of college. His conclusion: if you don't build technology for learning, generic video conferencing can't be copy-pasted into education.

02

Indian education changed in three waves; parents drove the last

First privatisation widened access beyond the school, then smart boards let children visualise for the first time what black-and-white textbooks only described, and finally parents took charge and started spending outside the school system. That third wave created B2C edtech — and left schools a few years behind their own consumers, with teachers managing 40-50 varied children who sometimes know more than they do.

03

Design for nocturnals — the 4A loop

Infinity Learn's flow is assessment, assignment to a batch with teacher-led guided learning, self-learning material, and always-on doubt support — and because doubts pick up at 10 pm and run past 1 am, the company reorganised around AI engines plus human faculty at those hours. The loop is optional: a student coaching elsewhere can come only to test against a hundred thousand Sri Chaitanya peers, since learners choose what they want rather than being forced down one path.

04

The cohort is technology's real edge over brick and mortar

Self-learning throws off data on exactly where a child is struggling, and on whether the problem is individual or class-wide. Struggling students from multiple batches get pulled into a temporary cohort for two or three classes on, say, algebra, brought up to standard, then redistributed. You don't have to march everybody down the same path — which, Singh argues, is the point of using technology at all.

05

Buy only what integrates; partner for what you can't build

The strategy was fixed in Jan-Feb 2021: acquire what is easy to integrate — Teacherr for teacher onboarding, Don't Memorise for supplementary content that takes a learner outside the curriculum and brings them back — and partner for what you can't achieve alone. Hence Amazon Academy running largely on Sri Chaitanya faculty: collaborating and competing with Amazon at once, a partnership Singh credits with teaching the company customer service.

06

Growth versus revenue is a choice he refuses to make

When a team member said they would have to choose between growth and revenue, Singh asked why not both — the company has 100,000 paid learners and refuses free-learner growth theatre. He cites Zerodha as the model, treats demand from the Sri Chaitanya group as a safety net on top of which a 2-3x external business must be built, and says private equity will come, because 'this business is built for that'.

07

The learner's life hasn't changed — the industry's open question

This is the best time in Singh's 22 years: IIT, IIM and IISc graduates now choose education as a career, and the sector has generated real wealth. But the learner has merely moved from one classroom to an online one and back; the sanctum — where teacher meets learner, as deity meets devotee in a temple — is what the industry has not yet made better.

08

Enable, don't control; and change the question at home

Government's job is enablement — Singh points to Brazil, where schooling runs privatised until the state examines everyone at grade 12 — because control won't let education flourish. Parents, meanwhile, should stop auditing the teacher and ask 'what did you learn today', where a football dribbling trick or a paper airplane counts as learning.

Lines that stay

If you don't build technology for learning, then normal technology for video conferencing can't be copy-pasted.

— Ujjwal Singh ▶ 15:59

Our doubts pick up at 10 o'clock in the night and go up to 1 o'clock. We realised we are dealing with nocturnals — we have to change ourselves to adapt to them.

— Ujjwal Singh ▶ 19:28

Imagine a temple: inside the sanctum there is a deity and a human being praying — that's the place where the actual thing happens. For us, that is the classroom, where there's a teacher and a learner. How can we make that better?

— Ujjwal Singh ▶ 35:21

When a child comes back home, change the question from 'what did the teacher teach' to 'what did you learn today'. He might have learned a dribbling trick, or flying paper airplanes — and trust me, that's equally good learning.

— Ujjwal Singh ▶ 39:08

If you want to be ordinary, you don't have to leave anything — keep continuing. But if you want to do extraordinary, you have to do extra. At the end of the day there are only eleven players in an Indian cricket team.
