AppFactor, an agentic orchestration platform startup that delivers autonomous maintenance for enterprise software, has raised £3 million in a seed round led by Tensor Ventures, with participation from Begin Capital, Adara Ventures and Narwhal Investments. The funding will accelerate go-to-market efforts and expand the platform’s capabilities, including autonomous refactoring that transforms legacy software into self-maintaining, secure, cloud-ready assets.
AppFactor is designed to free developers from ongoing maintenance work such as bug fixes, vulnerability patches, dependency updates, and code smell remediation. The platform operates as an orchestration layer of specialised agents that handle everything from routine fixes to full-scale code migrations and rewrites, allowing engineering teams to focus on designing new features that drive business results. While the industry races to embed AI assistants into code editors, AppFactor has a fundamentally different vision: software that maintains itself and evolves without a developer ever opening an IDE.
The platform includes a dynamic discovery system that scans where software is running to identify vulnerabilities, code smells, and infrastructure misconfigurations in real time. It works through existing enterprise workflows such as pull requests, approval gates, and established code review processes, with full auditability and opportunities for review before changes are released. Initial large enterprise customers are already using the technology to compress modernisation timelines and shift applications to more cost-efficient operating patterns.
