Resolve AI Inc., a startup that helps enterprises make their infrastructure more reliable, has raised $40 million in funding.

DST Global and Salesforce Ventures led the investment. It comes as an extension to a $125 million Series A round that Resolve AI announced in early February. The company said today that it’s now valued at $1.5 billion, which represents a $500 million increase in under three months.

Resolve AI sells a software platform that can investigate issues in production environments. Such environments, which host the applications that power a company’s day-to-day operations, are more difficult to troubleshoot than less critical systems because of their complexity. A production cluster comprises upwards of hundreds of software components and infrastructure assets.

When administrators receive an error alert, they can enter it into Resolve AI and ask the platform to investigate. The software often kicks off the process by checking whether the affected system experienced other errors. Additionally, it identities any configuration changes that administrators may have made immediately before the incident. Such modifications often factor into outages.

Resolve AI assembles the data points that it collects into a timeline of what went wrong and when. The timeline is compiled by artificial intelligence agents that also highlight the most likely root cause. For example, Resolve AI could determine whether an application outage is caused by a code quality issue or a malfunction in the underlying server.

The platform also provides administrators with other information. The built-in agents can generate technical charts that describe an outage’s impact on users. The graphs are displayed alongside natural language troubleshooting suggestions.

Fixing outages is not the only task that the software promises to ease. Administrators can ask its platform for pointers on how to make a production environment more cost-efficient. The software identifies workloads that could be moved to smaller, less expensive cloud instances to cut costs.

Resolve AI can also help users make more complicated changes. In a demo published on the company’s website, an engineer asked the platform to design a rate limiter, a software engine that regulates the flow of traffic between applications. Resolve AI built the tool using a combination of custom code and open-source components.

The company says its software has been adopted by Salesforce Inc., DoorDash Inc. and other major tech firms. It will use its newly raised capital to expand the platform’s capabilities. The effort will be partly by a newly formed engineering team called Resolve AI Labs. The team will develop AI models optimized to analyze technical data such as error logs and application performance metrics.

“Foundation models are improving quickly, but they are still not enough for production operations,” said founder and Chief Executive Spiros Xanthos. “Production environments demand reasoning over fragmented telemetry, long-running workflows, constantly changing systems and a very high bar for accuracy.”
