ChatGPT took the world by storm when it launched in November 2022. Within just five days, it reached one million users — faster than any product in history. But who built it? Who owns it? And what is the story behind OpenAI, the company that created the most famous AI in the world? Here is everything you need to know.
What is OpenAI?
OpenAI is an American artificial intelligence research company founded in December 2015. Its stated mission is to ensure that artificial general intelligence (AGI) benefits all of humanity.
OpenAI started as a non-profit organization but later created a “capped-profit” subsidiary to attract the massive investment needed to develop cutting-edge AI systems. This unique structure means profits are capped, with the non-profit board maintaining control over the company’s direction.
Company facts:
- Founded: December 11, 2015
- Headquarters: San Francisco, California, USA
- CEO: Sam Altman
- Valuation: Over $80 billion (2024)
- Employees: Over 1,500
The Founders of OpenAI
OpenAI was co-founded by a group of some of the most prominent names in technology and AI research. Here are the key founders:
Sam Altman — CEO
Sam Altman is the face of OpenAI and one of the most influential people in the technology industry today. Born in 1985 in Chicago, Illinois, Altman showed an early passion for computers and programming.
He studied computer science at Stanford University but dropped out to co-found Loopt, a location-based social networking app, at just 19 years old. After selling Loopt, he became president of Y Combinator — the world’s most prestigious startup accelerator — where he mentored hundreds of successful companies including Airbnb, Dropbox, and Reddit.
In 2015, Altman co-founded OpenAI and became its CEO. Under his leadership, OpenAI developed GPT-3, GPT-4, DALL-E, and ChatGPT — products that fundamentally changed the world’s relationship with artificial intelligence.
In November 2023, Altman was briefly fired by OpenAI’s board in a dramatic boardroom coup — only to be reinstated just five days later after massive pressure from employees and investors. The event made global headlines and highlighted his central importance to the company.
Elon Musk — Co-Founder (departed 2018)
Elon Musk was one of OpenAI’s original co-founders and provided significant early funding. He contributed approximately $100 million to help launch the organization.
Musk departed from OpenAI’s board in 2018, citing potential conflicts of interest with Tesla’s AI development. Since leaving, he has become one of OpenAI’s most vocal critics, arguing that the company has strayed from its original non-profit, open-source mission.
In 2023, Musk founded his own AI company called xAI, which developed the Grok AI assistant integrated into his social media platform X (formerly Twitter).
Greg Brockman — Co-Founder & President
Greg Brockman is OpenAI’s President and one of its most important technical leaders. He studied mathematics at Harvard and computer science at MIT before dropping out to become CTO of Stripe, one of the world’s most valuable fintech companies.
Brockman joined Altman to co-found OpenAI in 2015 and has been instrumental in building the technical infrastructure behind ChatGPT and GPT-4.
Ilya Sutskever — Co-Founder & Chief Scientist
Ilya Sutskever is widely regarded as one of the most brilliant AI researchers in the world. Born in Russia and raised in Israel, he completed his PhD under AI pioneer Geoffrey Hinton at the University of Toronto.
Sutskever was a key researcher at Google Brain before co-founding OpenAI. He has been the driving force behind many of OpenAI’s most important technical breakthroughs. Notably, Sutskever was one of the board members who voted to fire Sam Altman in November 2023, though he later expressed regret about that decision.
The Story of ChatGPT
ChatGPT was launched on November 30, 2022, as a research preview. OpenAI expected modest interest from researchers and developers — instead, it became a global phenomenon overnight.
ChatGPT milestones:
- Day 1: Server crashes due to overwhelming demand
- Day 5: One million users
- Month 2: 100 million users (fastest ever for any consumer app)
- 2023: 1 billion weekly visits
- 2024: Integration into Microsoft Office, Bing, and hundreds of other products
- 2026: Over 200 million active users worldwide
The success of ChatGPT triggered an AI arms race among the world’s biggest technology companies, with Google, Meta, Amazon, and Apple all accelerating their AI programs in response.
Microsoft’s Massive Investment
One of the most significant developments in OpenAI’s history is its partnership with Microsoft. In 2019, Microsoft invested $1 billion in OpenAI. In 2023, following ChatGPT’s explosive success, Microsoft invested an additional $10 billion.
This partnership gave Microsoft the rights to integrate OpenAI’s technology into all of its products, including Windows, Office 365, Teams, Bing, and Azure cloud services. The result was Microsoft Copilot — an AI assistant built into virtually every Microsoft product.
Microsoft now holds approximately 49% of OpenAI’s capped-profit subsidiary, making it the company’s largest investor and most important commercial partner.
OpenAI’s Most Famous Products
Over the years, OpenAI has released several groundbreaking products that have shaped the AI industry:
GPT Series — The Generative Pre-trained Transformer models that power ChatGPT. GPT-1 was released in 2018, GPT-2 in 2019, GPT-3 in 2020, and GPT-4 in 2023. Each version has been dramatically more capable than the last.
ChatGPT — The conversational AI chatbot that brought AI to the mainstream. Available at chat.openai.com with both free and paid tiers.
DALL-E — An AI image generation system that creates stunning images from text descriptions. DALL-E 3 is integrated directly into ChatGPT Plus.
Whisper — An open-source speech recognition system that converts audio to text with remarkable accuracy.
Sora — An AI video generation model announced in 2024 that creates realistic videos from text prompts, representing the next frontier of generative AI.
Codex — An AI system trained on code that powers GitHub Copilot, helping millions of developers write better code faster.
Controversies and Challenges
OpenAI’s rapid rise has not been without controversy:
The November 2023 Boardroom Drama — Sam Altman’s sudden firing and reinstatement in November 2023 shocked the tech world and raised serious questions about OpenAI’s governance structure.
Privacy Concerns — ChatGPT has faced scrutiny from regulators in Europe and elsewhere regarding data privacy and the use of personal information for AI training.
Copyright Issues — Multiple lawsuits have been filed by authors, artists, and news organizations claiming that OpenAI trained its models on copyrighted material without permission.
Competition from rivals — Google’s Gemini, Anthropic’s Claude, and Meta’s Llama have all emerged as serious competitors, challenging OpenAI’s dominance in the AI market.
The Future of OpenAI
OpenAI’s stated goal is to develop Artificial General Intelligence — AI that can perform any intellectual task that a human can do. Whether and when AGI will be achieved remains one of the most debated questions in science and technology.
What is certain is that OpenAI will continue to be at the center of the AI revolution for years to come. With billions in funding, the world’s best AI researchers, and products used by hundreds of millions of people, the company’s influence on the future of technology is immeasurable.
Final Thoughts
OpenAI and ChatGPT have fundamentally changed the world in just a few years. What started as a non-profit research lab founded by a group of visionaries has become one of the most valuable and influential technology companies in history.
