Resolve AI has secured unicorn status with a $1 billion valuation following the close of its Series A funding round in December 2025, positioning the autonomous site reliability engineering startup for accelerated growth into 2026. The investment round led by Lightspeed Venture Partners marks a significant milestone for enterprise AI infrastructure companies.

Resolve AI Valuation Structure and Investment Details

The headline valuation for Resolve AIs Series A reached $1 billion, though industry sources indicate the company utilized a multi-tranched investment structure. Under this approach, investors acquired equity at varying price points, with some shares purchased at the $1 billion valuation while a larger portion was secured at lower valuations.

This investment structure has become increasingly popular among sought-after AI startups, allowing companies to achieve headline unicorn status while providing investors with blended entry points that reflect both current traction and future growth potential.

The companys annual recurring revenue stands at approximately $4 million, demonstrating early enterprise adoption of its autonomous site reliability engineering platform. While the specific funding amount remains undisclosed, the valuation multiple suggests strong investor confidence in Resolve AIs technology and market opportunity.

Leadership and Founding Team

Resolve AI was founded by Spiros Xanthos and Mayank Agarwal, former executives at Splunk, the enterprise observability platform acquired by Cisco in 2024. Xanthos served as a senior executive at Splunk, while Agarwal held the position of Chief Architect for Observability.

The co-founders partnership spans over two decades, originating from their graduate studies at the University of Illinois Urbana-Champaign. Their previous collaboration produced Omnition, an observability startup that Splunk acquired in 2019, providing the founders with deep expertise in enterprise infrastructure monitoring and incident response.
