Artificial intelligence is the use of machines to mimic human intelligence.

Best AI start-ups

Best AI start-ups to watch this year

1. OpenAI

As you might expect, ChatGPT owner OpenAI has received much of the attention in AI start-ups this year, and continues to set the pace in its cohort.

OpenAI has developed other renowned products, including its image-generating AI, DALL-E, and text-to-video AI, Sora. Its success with ChatGPT and its high-profile partnership with Microsoft (MSFT -0.97%) makes it the premier AI start-up these days.

OpenAI was founded in 2015 with several co-founders, including Elon Musk, though Musk eventually left the company to work on Tesla (TSLA 0.67%) and SpaceX.

AutoGPT

AutoGPT is an artificial intelligence (AI) agent that can complete complex tasks without human intervention.

In March of 2025, Open AI raised $40 billion at a valuation of $300 billion, making it the largest private tech funding round on record.

The round was led by SoftBank (SFTBF 3.43%), the prolific tech investor, which invested $30 billion; Microsoft and venture capital firms made up the remaining $10 billion. The Stargate Project, a joint venture between Softbank, OpenAI, and Oracle that was announced at the White House in January, is expected to receive $18 billion. Stargate aims to invest as much as $500 billion in AI infrastructure in the U.S.

Key facts:

Founded in 2015
Headquartered in San Francisco
Industries served: Technology, education, retail, manufacturing, healthcare, and others.
Services provided: Foundation models including GPT and DALL, chatbots, enterprise services, and an API platform.

2. Anthropic

Anthropic is rapidly emerging as the chief start-up rival to OpenAI.

Founded in 2021 by former OpenAI researchers, Anthropic counts Google and Amazon (AMZN 0.32%) as major investors. The Alphabet (GOOG 0.1%) (GOOGL 0.13%) subsidiary took a 10% stake in 2023, and Amazon has invested $8 billion in Anthropic. After its most recent funding round in March, it's valued at $61.5 billion, rising $3.5 billion at the time. Anthropic also counts Salesforce (CRM -3.33%) and Zoom (ZM -2.14%) as investors.

Anthropic is best known for its generative AI chatbot, Claude, which it launched in March 2023. Some users think Claude is friendlier than ChatGPT, though they say that ChatGPT is better for analyzing and summarizing documents. It's also said to be more versatile than Claude.

According to some reviews, Claude gets better results with things like creative tasks, following instructions, and answering trivia questions.

Anthropic describes Claude as being "much less likely to produce harmful outputs, easier to converse with, and more steerable" than other AI chatbots. In other words, Claude seems designed to avoid some of the problems that have plagued ChatGPT and Google's AI chatbots.

Key facts:

Founded in 2021
Headquartered in San Francisco
Industries served: Technology, healthcare, customer support, finance, and others
Services provided: Claude AI models, focus on AI safety, enterprise services, cloud partnerships.

3. Perplexity AI

Valued at $14 billion as of May 2025, Perplexity AI is another promising AI start-up.

Perplexity is backed by Softbank's Vision Fund, the prolific start-up investors known for backing companies like Uber (UBER 3.76%), DoorDash (DASH 5.0%), Arm Holdings (ARM -0.51%), and WeWork. Perplexity has also raised money from Nvidia (NVDA 0.6%), Amazon founder Jeff Bezos, and Shopify (SHOP -2.5%) CEO Tobi Lutke.

Perplexity has differentiated itself from other AI chatbots with a focus on search tools that feature sources and citations. Some see Perplexity as the best AI alternative to a traditional Google search. In fact, both Apple (AAPL 3.09%) and Samsung (SSNL.F 9.01%) are considering integrating its search engine into their hardware.

Perplexity said it crossed $100 million in annualized revenue March with 6.3x growth in Perplexity, its paid subscription tier.

Key facts

Founded in 2022
Headquartered in San Francisco
Industries served: Education, healthcare, media and entertainment, travel, and others
Services provided: Real-time search, citations, conversational interface, file uploads, and others.

4. xAI

Elon Musk has had his hand in a wide range of emerging technologies, including electric vehicles, renewable energy, spacecraft and rockets, and satellite internet, so it shouldn't come as a surprise that he also has an AI start-up. (Musk was even a co-founder of OpenAI, although he left that company in 2018.)

xAI, his AI start-up, is one of the most valuable today, and in June 2025 was aiming for a funding round with the help of Morgan Stanley (MS -0.28%) that would value the company at more than $100 billion in a deal that includes $5 billion debt and $20 billion in equity.

xAI is the creator of Grok, the chatbot featured on the social media platform X, which Musk also owns. That gives xAI something of an advantage since most AI start-ups don't have an allied platform like X that can help draw users to the product. Some users think Grok is less censored than ChatGPT.

Key facts:

Founded in 2023
Headquartered in San Francisco
Industries served: Technology, finance, healthcare, autonomous vehicles, manufacturing, and others.
Services provided: Grok chatbot, models for developers, and enterprise services.

5. Mistral AI

Mistral AI is one of the youngest AI start-ups to make a splash in the industry. The company was able to easily raise money since it was founded by execs from Meta Platforms (META -1.35%) and Google.

After a funding round in June 2024, the start-up is now valued at $6.2 billion, raising $640 million from the likes of Andreessen Horowitz, Nvidia, and Samsung.

Mistral is unique among AI start-ups. It's based in France and has received a strong endorsement from the French government. It takes an open-source approach to AI, meaning its code is available to anyone who wants to use it. It's chatbot is called Le Chat and is known for being strong in a wide range of languages.

Key facts:

Founded in 2023
Headquartered in Paris
Industries served: Financial services, healthcare, customer support, education, and others
Services provided: Large language models, API access, open-source models, cloud-based access.

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 just 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 generative AI as 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 December 2024, the company was valued at $62 billion after raising $10 billion. Databricks has been one of the more anticipated 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.

8. Cohere

Founded in 2019 by ex-Google AI researchers, Cohere is an enterprise AI platform focused on large language models and natural language processing.

Cohere allows developers and businesses to build their chatbots and virtual assistants, and the company also provides services like data analysis and search.

The company aims to provide higher performance and accuracy with a specific focus on the enterprise market. Cohere reached an annualized revenue of $100 million in May 2025, and its valuation was $5.5 billion as of June 2025. It counts Nvidia and Cisco (CSCO 0.96%) among its backers.

Key facts:

Founded in 2019
Headquartered in Toronto
Industries served: Financial services, healthcare, manufacturing, retail, and others
Services provided: LLMs, API access, text generation, summarization and data extraction.

Should you invest?

Should you invest in AI start-ups?

Start-ups, by definition, are privately held, which means it's difficult for retail investors to invest in them.

However, there are ways to get exposure to AI start-ups. The easiest way is by investing in a publicly traded company that has a stake in an AI start-up. For instance, you could buy shares of Microsoft, which would give you indirect ownership of OpenAI. Similarly, you could buy stock in Alphabet to get exposure to Anthropic.

Investors should remember that start-ups tend to be riskier than publicly traded companies, and many start-ups won't succeed. However, if you find an AI start-up that looks promising, it's worth investigating if any publicly traded companies have a stake in it.

Investors looking for opportunities in artificial intelligence can also consider investing in AI stocks or AI ETFs.
