About Bhanu
Who is Neelakantha
Bhanu Prakash?
Born on October 13, 1999, in Eluru, Andhra Pradesh, Neelakantha Bhanu Prakash's journey into mathematics began through extraordinary adversity. At age five, while riding a bike, he was involved in a collision with a bus — leaving him with a severe head injury, a fractured skull, and 70 stitches. He spent the next year bedridden, recovering in the ICU.
⚡ The Origin Story
"My parents were told I might be cognitively impaired. So I picked up mental maths for survival — to keep my brain engaged." The doctor's prescription became a superpower that would one day make him the fastest human calculator in history.
Bhanu completed his schooling at Bharatiya Vidya Bhavan's Public School in Hyderabad before earning a B.Sc. (Hons.) in Mathematics from St. Stephen's College, Delhi. By the time he graduated, he had already won the National Speed Math Championship in 2011 and 2012, the International Speed Math Championship in 2013, and broken records held by both Shakuntala Devi and Scott Flansburg.
In 2020, at just 20 years old, he competed on the world stage for the first time — the Mental Calculation World Championship at the Mind Sports Olympiad in London. He defeated 29 competitors from 13 countries, performing calculations so fast that judges made him perform even harder problems just to confirm his accuracy. He won gold — becoming the first non-European and first Asian to ever win the championship.
Since then, Bhanu has conducted over 500 stage shows across 23 countries and given 5 TEDx talks, using every platform to highlight a sobering statistic he discovered in his travels: 3 out of 4 students worldwide suffer from math anxiety. In India alone, over 187 million of 250 million school students struggle with basic calculations.

Philosophy
Rethinking Math Education
from the Ground Up
Bhanu's world records aren't the goal — they're proof of a method. Every principle he used to become world champion is embedded in Bhanzu's curriculum.
Concept-First Teaching
Bhanzu teaches the "why" before the "what" or "how." Understanding the logic behind a formula builds intuition that rote memorisation never can.
Math as a Mind Sport
Speed math isn't just for competition — it builds faster cognitive ability and logical reasoning. Bhanu promotes mental math as a sport accessible to every student.
Learning Through Play
Stories, games, Brain Gym challenges, and live quizzes make math genuinely engaging — not a chore. When math is fun, students ask for more of it.
AI-Powered Personalisation
Bhanzu Buddy — a 24/7 AI assistant — gives personalised feedback, step-by-step guidance, and grade-specific explanations to every student, at any time.
Growth Mindset
Bhanu's curriculum is built on the belief that every child can be math confident. The platform uses competitive learning and peer leaderboards to fuel ambition.
Global Math Literacy
From Hyderabad to Texas — Bhanzu now operates in 20+ countries, with Bhanu's 500+ stage shows and TEDx talks having reached students on every continent.

Exploring Infinities → Bhanzu
Bhanu's journey began with "Exploring Infinities" — workshops in 50+ schools. After reaching 1M+ students and 100K+ teaching hours, the brand evolved into Bhanzu in 2020.
First US Learning Center — McKinney, Texas (Nov 2025)
Bhanzu opened its first physical US learning center in North Texas, serving K-9 students. Texas was chosen because it's one of the few states not on Common Core math standards — an opening for Bhanzu's concept-first approach.
Middle East, Southeast Asia & Australia
Following rapid adoption in the USA, Bhanzu has expanded across the Middle East, Southeast Asia, and Australia, with active student communities in each region.
Government Partnerships
Collaborated with the Telangana government and international NGOs to impact over 2 million children through structured numeracy programmes — going beyond ed-tech into public education reform.

MK
★★★★★
We've had a wonderful experience with this online math class. My daughter genuinely looks forward to each session, which says a lot about how engaging and well-structured the lessons are. The instructor explains concepts clearly and makes learning enjoyable, helping build both understanding and confidence. Since she started the class, I've noticed a clear improvement in her grades as well as her overall attitude toward math. She is more confident when solving problems and even takes initiative to practice on her own. I highly recommend this class to any parent looking for a supportive and effective way to help their child excel in math.

My 7 year old daughter finished 6 modules already and is already surprising us with her maths. Bhanzu made our life easy by teaching her all the essential mathematics at her age including Addition, Subtraction, Multiplication, Division, Fractions, Decimals, Shapes & Measurements. She is Now ahead of all her friends in the class and extremely excited to complete rest of the modules and see her growth in other areas of the course. Highly recommended for all parents.

My 6 year old son Raayo has become a little Math wizard. He learnt to do mental math and his confidence level in solving math problems is so good. We are very happy with the program. It is focused on advanced Math learning for students who wants to be ahead in class.
CJ
★★★★★
Our kids, 6 and 7 years old, are now able to multiply multiple digits by a single digit after just 4-5 months of Bhanzu lessons. They also learned to add, subtract, and multiply in multiple ways so that they can have a firm understanding of the math concepts. The teachers are all very kind and patient; sometimes too patient, to be honest! My only complaint is that the teachers' strong accent makes it difficult to understand, but the kids eventually get used to it.

It's my son's second year continuing it and it is worth taking it. I recommend Bhanzu to everyone for their kids bright future. The last thing I am very very satisfied if their communication, customer satisfaction & overall the team is excellent. Very cooperative and keep connected until a problem resolved. Thank you Bhanzu for having this curriculum that is so helpful for our kids.
