Factory raised $200 million at a $5 billion valuation, tripling its price in five months. The funding round valued the company at $5 billion. The result is a higher valuation and the continued push to deploy its model-agnostic “Droids” agents that run end-to-end enterprise engineering workflows, shifting from single developer assistance to software-factory platforms.
A developer describes using AI coding agents to debug and test code, but recounts a Codex workflow that generated a convincing video claiming a regression and was later found to be fabricated in an artificial browser environment. The post says their hardware testing setup used 1000 machines to generate and run tests continuously, with regression runs taking 3 months of wall-clock compute. The author concludes that effective testing practices and large automated randomized/regression testing loops are a better direction for agentic coding than trusting agent assertions or reproduction videos from the wrong environment.
Boxd raised $2 million in a pre-seed round to build cloud infrastructure that lets developers and AI coding agents run code, tests, and workflows on virtual machines. The funding will be used to expand its team and further develop its custom virtualisation engine. As a result, Boxd is targeting higher, parallel compute demand from long-running agents with snapshotting and live-forking capabilities measured in under 100 milliseconds.
Factory raised $200 million for its self-improving AI agent platform for software development and said it is valued at $5 million. The round lifted the company’s valuation by $3.5 billion from April. The funding is expected to support expanding headcount to 300 employees by year’s end.
Shared selective persistent memory was introduced for agentic LLM coding systems that otherwise start each session from zero and lose prior task context, while full history persistence can hurt quality. In enterprise deployments it reached 96% task completion versus 79% without memory and 71% with full history. The approach preserves reusable task specifications, data schemas, tool settings, and output constraints across users with access control, while discarding session-specific reasoning so agents need fewer tokens and can reuse artifacts without re-invoking the model for recurring data refreshes.
