Resolve AI, a startup building an autonomous site reliability engineer (SRE), has reportedly raised a Series A round led by Lightspeed at a valuation of around $1 billion. The funding, reported on December 20, 2025, comes with round size undisclosed and follows a prior $35 million seed led by Greylock.

Resolve AI’s rise to a reported $1 billion valuation on roughly $4 million of ARR underlines how aggressively markets are valuing AI-native automation of core software operations. Automating SRE work—detecting incidents, diagnosing root causes, and applying fixes—sits very close to the critical path of keeping large AI and non-AI systems online. If Resolve AI can reliably replace or augment human SREs, it lowers one of the operational bottlenecks that currently limits how aggressively companies can deploy complex AI workloads.([indexbox.io](https://www.indexbox.io/blog/resolve-ai-reaches-1-billion-valuation-in-series-a-led-by-lightspeed/))
From an AGI race perspective, this is an enabling-layer play: more robust, self-healing infrastructure makes it cheaper and less risky to run huge training runs, complex agentic systems, and dense microservice meshes. It echoes a broader trend where AI is increasingly being pointed at the software and infrastructure stack itself, not just end-user tasks. Strategically, Lightspeed’s involvement signals that leading VCs see autonomous operations as an important part of the AI stack, alongside chips, models, and applications. That puts pressure on traditional observability and DevOps tooling vendors to incorporate much more autonomy, or risk being leapfrogged.
If these systems work as advertised, they’ll also change the labor market for ops: fewer humans on call for rote incident response, more humans supervising AI-driven runbooks, policy, and safety controls.
