Sweep builds an AI "junior dev" that lets engineers describe requests in natural language (e.g., add debug logs) and then generates, tests, and pushes Python code via pull requests while addressing reviewer comments. The product combines OpenAI's GPT-4 with a custom Python code search engine using lexical and vector search and runs tests in real time, with a focus on unit-test generation, refactoring, and other tech-debt work. Sweep emphasizes repository-wide changes, error logging improvements, and automating leftover TODOs; it asks users to review generated code before merging to mitigate reliability and copyright risks. The company currently charges $480 per seat per month and says customer revenue, along with a war chest totaling $2.8 million, gives it runway "for years." Sweep plans to expand its team from two employees to five and to augment its models with StarCoder and models from Hugging Face and ServiceNow. TechCrunch previously covered Sweep during Y Combinator's Summer 2023 Demo Day; founders William Zeng and Kevin Lu are both veterans of Roblox.
