Delty is an AI Staff Engineer platform, accessible at delty.ai, designed to assist engineering teams in designing and scaling enterprise software by acting as a knowledgeable teammate. Unlike traditional AI code generators, Delty is trained on a company's specific codebase, documentation, and systems, enabling it to offer architectural design guidance, system-level insights, and support for onboarding new engineers.
Delty's core offering centers on enabling users to:
- Design software features and services with system-aware AI that deeply understands their stack.
- Enhance tools like Copilot by adding engineering context from internal systems and documentation.
- Ask complex technical questions and receive informed, context-rich answers tailored to their organization's environment.
How Was Delty Started?
Delty was founded by a team with deep experience in large-scale engineering and AI. The founding team includes Lalit Kundu, an ex-Staff Engineer at YouTube, ACM-ICPC world finalist, and CEO of Delty, and Catherine Zhao, who previously worked on ChromeOS and enterprise AI agents at Google.
