Unicorn

By 2019, Scale AI hit “unicorn” (a start-up company valued at $1 billion) status. Wang was just 22. Among companies on Scale AI's client list:

  • OpenAI (data labeling, preparation for AI models)
  • Lyft (helping in the development of their self-driving tech)
  • Tesla (data for autonomous driving)
  • C3.ai (cross-industry AI data annotation)
  • Airbnb (data annotation for user experiences, improvements)
  • Pinterest (image recognition, content understanding capabilities)
  • Uber (data processing, machine learning)

But Wang wasn't done. He set his sights on an even bigger target: The US government. In 2020, the Department of Defense came asking for help with:

  • Satellite imagery analysis
  • Drone footage processing
  • Predictive maintenance for vehicles

So then, Wang’s technology was safeguarding national security. As AI grips the world, Scale AI has become indispensable.

Scale AI is training cars to outsmart human drivers, helping Nvidia see the world in 1s and 0s, and keeping Meta's feed clean of digital toxins.

One of the key problems his company is solving: using AI to analyze massive amounts of imagery and detect objects — because humans can’t just keep up.

“AI can also be used for change detection. Simply put, algorithms can constantly monitor imagery, and notify a human to investigate further if there’s a change or a movement,” Wang explained in a TED talk.

So the world’s top 300+ companies now relied on Wang's magic.

For Wang, success isn't just about building cutting-edge technology—it's about living on the edge of information. At Quora, where he once worked as a pro coder at age 15, Wang saw how AI could be the key to unlocking solutions for the world's most daunting challenges, including climate change, agriculture, medicine discovery and global conflicts.

Wang believes that AI will revolutionize the world, just like computers and smartphones have.

The opportunity was right there, waiting to be seized. But here's what truly sets Wang apart—his ability to weave emotion and storytelling into his work.

He knew that people’s feelings drive decisions more than anything else. Whether leading a team, building a brand, or selling a product, it’s all about telling a story that stirs something deep inside.

Data will be a new kind of ammunition in the era of AI warfare.

- Alexandr Wang

His posture is reflected in the emotional stories he tells, and the challenge he poses: “We’re like to see a new calculus on AI. It’s uncharted territory, nobody knows what it will look like, or the toll it will take.

"How do we know if our AI is better than our adversaries’? We won’t. But one thing is clear: AI can only be as powerful as the underlying data that is used to fuel its algorithms. Data will be a new kind of ammunition in the era of AI warfare.”

Wang’s creativity doesn’t follow rules or play it safe. To him, there’s no "right" or "wrong"—just endless possibilities.

Fear of failure

Most people fear failure, but Wang thrives on it. He embraces the unknown, explores, and experiments relentlessly. It’s why, on September 17, 2024, he put out a bold call on Twitter:

"If you have 5+ years in a technical field or hold/are pursuing a PhD, we want your insights! We're seeking questions that would truly impress you if an AI could solve them. Help us evaluate how close we are to achieving expert-level AI across diverse domains."

For Wang, creativity is an experiment, a dance between of failure and innovation. He didn’t learn this from a textbook—he learned it from music, where every note is an exploration, and every mistake leads to discovery.

Alexandr Wang's guiding principles:

  • Always want more: Never settle, always push for better.
  • Build infrastructure: Lay the foundation for future growth.
  • Find core problems: Focus on what really matters.
  • Live at the edge of information: Stay ahead by always seeking the unknown.
  • Weave emotions into everything: Create stories that move people.
  • Embrace creativity: It’s not about being right—it's about daring to try.

These principles didn’t just help Wang build a billion-dollar company. Stories and emotions are powerful. They connect people, build trust, and inspire. 

Ultimate goal

On January 19, 2024, Wang turned 27. His net worth: $2 billion. But money wasn't the goal. Impact was. Wang's vision was to accelerate humanity's progress through AI.

How? By tackling some of the world's most pressing challenges.

Why labeling and tagging data is crucial:
• It enables machine learning models to learn, make predictions, and improve accuracy over time.

• Machine learning models rely on labeled data to understand patterns and relationships within the data. For example, in image recognition, a model needs labeled images—where each image is tagged with what it contains (e.g., "cat" or "car")—to learn to identify objects on its own. Without labeled data, the model wouldn’t know what it’s looking at.

• Improving accuracy and performance: Accurate labeling of data is vital for ensuring that machine learning models perform well. Poorly labeled or inconsistent data can lead to biased, inaccurate predictions, which reduces the model’s effectiveness. Quality labeled data ensures models can be trained to deliver high accuracy in tasks like language translation, object detection, and “sentiment analysis”.

• Handling large and complex datasets: Labeling and tagging allow data scientists to transform unstructured, raw data into structured, usable formats for AI. This is essential for industries like healthcare (where medical images are labeled for disease detection) or autonomous driving (where every object in a car’s surroundings must be labeled for safe navigation).

• Enabling supervised learning: Many machine learning techniques, especially supervised learning, require labeled data. In this approach, the algorithm learns from a set of input-output pairs where the desired outcome (label) is already known. The better the labeling, the more accurate the model’s predictions on unseen data.

• Facilitating continuous improvement: Data labeling isn’t just a one-time task. Machine learning models constantly need new, up-to-date labeled data to improve and adapt to changing environments. For example, a facial recognition model needs fresh data to keep up with new angles, lighting, or expressions, ensuring continuous improvement in performance.

• Enhancing AI in real-world applications: For AI to work effectively in real-world applications, it needs a large amount of contextual understanding that comes from labeled data. In natural language processing (NLP), tagging words or phrases with their meaning (e.g., identifying nouns, verbs, or sentiment) allows models to understand human language. Similarly, in autonomous vehicles, labeling road signs, pedestrians, and other objects is critical for safety.

• Enabling customisation for specific use cases: Businesses and industries often have specific needs that general-purpose AI models cannot meet without customisation. Labeling data helps create domain-specific models that are tailored to particular applications—whether it’s identifying defects in manufacturing or detecting fraud in financial transactions.

Scale AI began working on:

  • Climate change models
  • Drug discovery
  • Disaster response optimisation

The question wasn't if AI would change the world. It was how fast. And Wang was determined to push the boundaries.

His journey teaches us:

  • Spot invisible problems
  • Scale solutions globally
  • Aim for world-changing impact

It turns out the next big idea may not necessarily be found in a lab. It's with someone ready to drop everything and build it.

The AI revolution is just beginning. But here's the most exciting part, Wang's tech is:

  • Making roads safer
  • Boosting national security
  • Accelerating breakthroughs

It started with a teen who dared to think differently.

It is clear that AI is increasingly powering warfare. And based on the rate of progress in the AI field, I predict that in 10 years, it will be the dominant force.
