In a world dominated by Google, no one thought a startup could challenge the search giant. But in 2022, a 28-year-old from Chennai named Aravind Srinivas quit his job at OpenAI and did exactly that. He founded Perplexity AI — an "answer engine" that replaces traditional search with direct, AI-powered answers. Three years later, Perplexity is valued at $20 billion, and Srinivas has become India's youngest billionaire with a net worth of over ₹211 billion ($2.5 billion).
The Chennai Boy with a Dream
Aravind Srinivas was born on June 7, 1994, in Chennai, Tamil Nadu, into a middle-class family. His father, a retired banker, and his mother, a homemaker, provided a supportive environment where curiosity was encouraged. From an early age, Srinivas was fascinated by how things worked — especially computers and mathematics.
He graduated as the dual-degree computer science topper from IIT Madras, one of India's most prestigious technology institutes. His academic brilliance was just the beginning.
The Rare AI Trifecta: OpenAI, DeepMind, and Google Brain
After IIT Madras, Srinivas moved to the United States and earned a PhD in computer science from UC Berkeley. What followed was something very few people in the world have accomplished — he worked at all three of the most influential AI research labs:
- Google Brain — Where he gained deep expertise in large-scale machine learning
- DeepMind — Where he worked on cutting-edge AI research
- OpenAI — Where he witnessed the dawn of the GPT revolution firsthand
This rare combination of experiences gave Srinivas an unmatched understanding of how AI systems are trained, deployed, and scaled — knowledge that would prove invaluable when building Perplexity.
The Founding Moment: Weeks Before ChatGPT
In August 2022, just weeks before OpenAI would debut ChatGPT and change the world, Srinivas left his plum job at OpenAI to launch a startup with three co-founders — Denis Yarats, Johnny Ho, and Andy Konwinski — all AI experts with deep technical backgrounds.
At first, the startup's exact direction was unclear. But Srinivas remembers using their prototype and thinking it answered questions remarkably well. That experience crystallized the mission. As he liked to say, he was "replacing the search engine with an answer engine."
The 133x Growth: From $150M to $20 Billion
Perplexity AI's growth trajectory has been nothing short of extraordinary:
- Early 2023: Valued at $150 million
- January 2024: $522 million (Series B, led by Nvidia and Jeff Bezos)
- April 2024: Crossed $1 billion valuation — officially a unicorn
- June 2025: $14 billion ($500 million funding round)
- September 2025: $20 billion ($200 million round)
That's a 133-fold increase in less than three years. Total capital raised has now exceeded $1.02 billion across eight funding rounds, backed by names like Jeff Bezos, Nvidia, Tobias Lütke (Shopify CEO), and Databricks.
The Numbers That Shocked the Industry
By mid-2025, Perplexity was processing 780 million queries per month — up from 230 million in mid-2024 (a 240% growth). That's 30 million queries daily, with more than 20% month-over-month growth.
The company reached $200 million in annual recurring revenue (ARR) and was approaching profitability — all with just 247 employees. For perspective, Google has over 180,000 employees serving its search business.
India Expansion: 640% Growth
Perplexity expanded to India through a partnership with Airtel, one of India's largest telecom providers. The result was stunning — 640% year-over-year user growth in India, proving that Srinivas hadn't forgotten his roots.
Products: From Answer Engine to Agentic Browser
Perplexity continued innovating with products like:
- Comet Browser — An AI-powered agentic browser with 800+ app integrations
- Shopping Hub — AI-generated product recommendations, backed by Amazon and Nvidia
- Enterprise Solutions — Serving businesses with accurate, cited AI responses
India's Youngest Billionaire
In October 2025, Srinivas debuted on the M3M Hurun India Rich List with an estimated net worth of ₹211 billion (approximately $2.5 billion). At just 31 years old, he became India's youngest billionaire.
His journey — from a middle-class family in Chennai to helming a $20 billion company in San Francisco — represents more than individual success. It crystallizes the reshuffling of power and possibility that artificial intelligence is creating across the technology industry.
What Aspiring Founders Can Learn
- Deep expertise matters — Working at OpenAI, DeepMind, and Google Brain gave Srinivas insights no MBA could provide
- Timing is everything — He founded Perplexity weeks before the AI revolution (ChatGPT) began
- Challenge the giants — Taking on Google seemed impossible, but Srinivas believed a better answer experience was possible
- Stay lean — $200M ARR with just 247 employees proves that small, focused teams can compete globally
