Phoebe raises $17M Seed Round to build immune system for software

London-based AI startup Phoebe has raised $17 million in seed funding led by GV (Google Ventures) and Cherry Ventures, as the company accelerates development of its AI-powered reliability platform designed to act as the immune system for enterprise software.

Founded in 2024, Phoebe addresses one of the hardest challenges in modern software engineering, diagnosing and preventing failures across increasingly complex, distributed systems. Their approach? Deploying swarms of AI agents that continuously investigate live data (logs, traces, commits, and infrastructure signals) to proactively detect incidents, generate hypotheses, and propose preemptive code fixes via pull requests. Tasks that previously required manual investigation are compressed into short automations, enabling engineers to resolve incidents and prevent outages before they impact customers.

Already trusted by top engineering organizations including Trainline, PPRO, Freetrade, Volt, Yapily, and Lindus Health, Phoebe’s platform integrates with existing observability stacks in a vendor-agnostic, read-only manner.

The new funding round also brings GV partner Roni Hiranand onto Phoebe’s board, with Cherry Ventures providing strategic support as the company scales. With its team of former Google, Meta, Amazon, and Stripe engineers, Phoebe is positioned to redefine incident management and reliability engineering at scale. The fresh capital will help to fuel product development, AI research and customer expansion across the fintech, SaaS and global enterprise sectors.

Founders: Matt Henderson (ex-Stripe, Google, Amazon) and James Summerfield (ex-Stripe, CTO) - Both sold their first Start-Up Rangespan to Google in 2014
