GeeksforGeeks: How Sandeep Jain Built a Global EdTech Giant with a Passion for Teaching
If you have ever prepared for a software engineering interview in India, you have almost certainly used **GeeksforGeeks**. For over 15 years, this platform has been the silent architect of millions of tech careers. Sandeep Jain, the Founder and CEO of GeeksforGeeks, didn't start with a multi-million dollar pitch deck or a vision of becoming a "Unicorn." He started with a blog and a simple, burning passion for teaching. Today, his completely bootstrapped platform reaches 90-95% of the tech job market, proving that organic, content-driven growth can outscale even the most well-funded competitors.
Sandeep's journey is a masterclass in authentic entrepreneurship and extreme resilience. Born in Firozabad and educated in Hindi medium, his path took him from a Tier-3 college in Mathura to an M.Tech at **IIT Roorkee**, and eventually a prestigious software development role at **D.E. Shaw & Co.** But his heart remained in the classroom. In a daring move that shocked his family and society, he left his high-paying corporate job for a lower-salary teaching position at **JIIT Noida**, simply to have more time to write. That decision birthed GeeksforGeeks, a name inspired by an Orkut handle, which has now evolved from a simple algorithm blog into a full-stack edtech giant with its own job portal and premium courses.
The Content Magnet Model
Unlike many EdTech firms that spend millions on celebrity endorsements and TV ads, GeeksforGeeks spends almost nothing on marketing. By focusing on solving the actual interview questions being asked at tech giants like Google and Amazon, Sandeep built an organic traffic engine. Today, GeeksforGeeks is the first stop for Google search queries like "longest common subsequence," creating a massive, self-sustaining user loop.
The "Black Sheep" of the Family: Choosing Teaching Over DE Shaw
Sandeep Jain's early life was defined by the traditional Indian academic struggle. After two years of IIT-JEE preparation, he ended up in a Tier-3 engineering college where he realized a critical gap: "We were too much focused on academics... I had no idea how to prepare for a tech interview," he recalls. It was only during his M.Tech at IIT Roorkee that he saw the "inner workings" of top-tier placements.
After working at DE Shaw for 2.5 years, the bug for teaching—which he calls the "most fortunate thing that happened" to him—never left. He began blogging in 2008-09 under the name GeeksforGeeks, writing about the exact questions he faced in interviews. When the blog began to take off, he made the unthinkable decision: he moved to a teaching job with a significantly lower salary just to dedicate 5.5 years to growing the platform. "I was paying for the server cost from my salary," Sandeep admits, highlighting the early days of bootstrapped struggle.
"Entrepreneurship is more like running on a treadmill where the speed keeps increasing. The level of the game goes up and up with time. My secret to managing stress? I keep my expectations very low. I am ready to lose everything every day. If you have low expectations, you won't feel that stressed."
Phase 2: From Ad Revenue to an EdTech Empire
For a long time, GeeksforGeeks relied solely on ad revenue. But as the computer science job market grew, Sandeep recognized a new trend: engineers were willing to buy high-quality, specialized courses. He saw competitors charging ₹20,000 to ₹3 lakh for coding bootcamps and realized GeeksforGeeks could provide better quality at a fraction of the cost.
The GeeksforGeeks Growth Engine
- Crowdsourced Content: Articles are written by students and professionals, keeping the content aligned with current market trends.
- Strict Peer Review: A high rejection ratio ensures that only the highest quality, readable interview solutions are published.
- Feature Evolution: Adding compilers so users can run code directly within the article, bridging the gap between reading and practicing.
- Diversified Revenue: Expanding from ads into premium skill-based courses and a high-intent job portal for companies.
Scaling the "Teacher-Student" Bond
One of the unique advantages Sandeep had as a founder was his network at JIIT Noida. When it came time to hire, he didn't look for pedigreed recruiters; he hired his own students. "Almost everybody we hired initially was from that college... even our CTO and Sales Head today are from there," he says. This "Teacher-Student" bond created a level of loyalty and mutual respect that has powered the company for 15 years.
This community-first approach extends to the Campus Ambassador program, which helps GeeksforGeeks reach first-year engineering students across India. By introducing them to "Job-ready skills" early in their academic journey, the platform ensures it remains the dominant player in the student lifecycle.

Founder's Wisdom: Managing the "Treadmill"
Sandeep Jain views entrepreneurship as a treadmill that never slows down. He admits to making "classic geek mistakes"—focusing too much on the tech and ignoring marketing and HR until the team reached 20 people. He believes that while tech changes every four months, the fundamental principles of **perseverance and discipline** remain timeless.
Sandeep's Guide for Self-Taught Founders
Don't Over-Plan: In tech, you can't plan more than four or five months ahead. Move according to the market changes.
Value People Management: This is the trickiest part of the journey. Spend time becoming a better manager every single day.
Embrace Failure as a PhD: Every failure is a PhD into something. Don't repeat the same mistake and keep moving forward.
The Meaning of Entrepreneurship
For Sandeep Jain, entrepreneurship was never about the title; it was about the freedom to teach. Even as he nears the age of 40 and begins delegating more responsibility, his active involvement in the community remains his primary driver. As GeeksforGeeks expands its job portal and moves into beta for a new community interaction feature, it remains a testament to the power of a simple blog post.
In the high-decibel world of modern EdTech, Sandeep Jain and GeeksforGeeks are proving that you don't need a massive marketing budget to change the world. You just need to be the person who answers the student's question when they need it most. As he concludes: "Just keep your expectations low... everything works out."
