Key Points

Investor interest in AI start-ups like OpenAI has increased, driven by significant venture capital funding.
OpenAI, valued at $500 billion, leads in AI innovation with products like ChatGPT and partnerships with Microsoft.
AI start-ups are diversifying into areas like search tools and safety-focused chatbots, seeking market differentiation.

Investor interest is surging in all things AI, so it shouldn't come as a surprise that artificial intelligence (AI) start-ups are also popping up on investors' radars. Ever since the launch of ChatGPT, the potential for AI has crystallized across the business world and among investors, and the implications for the new technology are vast. AI start-ups are privately held companies that are developing AI technologies. This could include generative AI companies like OpenAI, physical AI, which includes robotics and automation like autonomous vehicles, and other types of artificial intelligence.

A new race is afoot among start-ups to challenge ChatGPT and, separately, to come up with the next big thing in generative AI.

6. Scale AI

Scale AI is different from other companies on this list because it doesn't make a chatbot or a generative AI interface. Instead, the company helps prepare data for AI training, a process called data labeling.

Scale AI's technology is impressive enough that Meta Platforms spent $14.3 billion on a 49% stake in the company, hoping it will accelerate its ambitions in AI. As part of the deal, Scale's 28-year-old CEO Alexandr Wang will join Meta and will reportedly lead a research lab at the tech giant. Given that Meta didn't take a majority stake, Wang's agreement to leave is a bit odd, but the relationship could favor Scale in the long run.

Key facts:

Founded in 2016.
Headquartered in San Francisco.
Industries served: Autonomous vehicles, healthcare, e-commerce, generative AI, robotics, and others.
Services provided: Data annotation/labeling, model training, human-in-the-loop labeling, and tools for building custom LLMs.

7. Databricks

Databricks is also unlike most of the AI start-ups on this list. It's older than the ones focused on generative AI since it was founded in 2013, and its focus is primarily on data analytics. Its AI platform offers machine learning and generative AI applications to help its customers deploy AI models.

As of August 2025, the company was seeking a valuation of more than $100 billion. Databricks has been one of the more anticipated initial public offerings (IPOs) for a while, but the company has not given any indication of when it will go public.

Key facts:

Founded in 2013.
Headquartered in San Francisco.
Industries served: Financial services, healthcare, retail, media, and others.
Services provided: Data lakehouse, machine learning platform, analytics platform.
