OpenAI has entered into a definitive agreement to acquire Neptune, a startup that builds monitoring and de-bugging tools that artificial intelligence companies use as they train models.

Neptune and OpenAI have collaborated on a metrics dashboard to help teams that are building foundation models. The companies will work “even more closely together” because of the acquisition, Neptune CEO Piotr Niedźwiedź said in a blog.

The startup will wind down its external services in the coming months, Niedźwiedź said. The terms of the acquisition were not disclosed.

“Neptune has built a fast, precise system that allows researchers to analyze complex training workflows,” OpenAI’s Chief Scientist Jakub Pachocki said in a statement. “We plan to iterate with them to integrate their tools deep into our training stack to expand our visibility into how models learn.”

OpenAI has acquired several companies this year.

It purchased a small interface startup called Software Applications Incorporated for an undisclosed sum in October, product development startup Statsig for $1.1 billion in September and Jony Ive’s AI devices startup io for more than $6 billion in May.

Neptune had raised more than $18 million in funding from investors including Almaz Capital and TDJ Pitango Ventures, according to its website. Neptune’s deal with OpenAI is still subject to customary closing conditions.

“I am truly grateful to our customers, investors, co-founders, and colleagues who have made this journey possible,” Niedźwiedź said. “It was the ride of a lifetime already, yet still I believe this is only the beginning.”

Microsoft pushed back on a report Wednesday that the company lowered growth targets for artificial intelligence software sales after many of its salespeople missed those goals in the last fiscal year.

The company’s stock sank more than 2% on The Information report.

A Microsoft spokesperson said the company has not lowered sales quotas or targets for its salespeople.

The sales lag occurred for Microsoft’s Foundry product, an Azure enterprise platform where companies can build and manage AI agents, according to The Information, which cited two salespeople in Azure’s cloud unit.

AI agents can carry out a series of actions for a user or organization autonomously.

Less than a fifth of salespeople in one U.S. Azure unit met the Foundry sales growth target of 50%, according to The Information.

In another unit, the quota was set to double Foundry sales, The Information reported. The quota was dropped to 50% after most salespeople didn’t meet it.

In a statement, the company said the news outlet inaccurately combined the concepts of growth and quotas.

“Aggregate sales quotas for AI products have not been lowered, as we informed them prior to publication,” a Microsoft Spokesperson said.

The AI boom has presented opportunities for businesses to add efficiencies and streamline tasks, with the companies that build these agents touting the power of the tools to take on work and allow workers to do more.

OpenAI, Google, Anthropic, Salesforce, Amazon and others all have their own tools to create and manage these AI assistants.

But the adoption of these tools by traditional businesses hasn’t seen the same surge as other parts of the AI ecosystem.

The Information noted AI adoption struggles at private equity firm Carlyle last year, in which the tools wouldn’t reliably connect data from other places. The company later reduced how much it spent on the tools.

Waymo on Wednesday said humans will begin test driving the Alphabet-owned company’s robotaxi vehicles in Baltimore, Pittsburgh and St. Louis.

The three cities represent the latest additions to Waymo’s quickly growing list of cities where the Google sister company is either operating its robotaxis, planning to launch service or starting to test its vehicles. That list now stands at 26 markets.

Waymo will begin manual drives in the trio of new cities this week with hopes to eventually begin serving fully-autonomous rides there, spokesperson Ethan Teicher told CNBC.

Over the past month, Waymo has been aggressively making announcements for new markets and developments at the Google sister company. This comes as tech rivals Amazon and Tesla made advancements in the robotaxi market in 2025. Amazon’s Zoox began offering free rides in Las Vegas and San Francisco, and Tesla this year launched ride-hailing service with human supervisors in the Austin and San Francisco markets.

In November, Waymo announced that it will soon begin manually driving in Minneapolis, Tampa and New Orleans. The company also added Houston, San Antonio and Orlando to its list of cities where it’ll launch service in 2026. Waymo also began offering rides on freeways in the San Francisco, Los Angeles and Phoenix markets, and it named a new finance chief.

With more than 250,000 weekly paid trips, Waymo’s robotaxi service currently operates in Austin, the San Francisco Bay Area, Phoenix, Atlanta and Los Angeles markets. The company in May said it had provided more than 10 million paid rides since launching in 2020.

The new cities further signal that Waymo is increasingly confident its service can work well in locations with colder weather conditions.
