About the company
Introduction to Sweep: An AI-Powered Code Assistant
Sweep is an AI-powered assistant that transforms feature requests and bugs into pull requests with code. Developers can simply message Sweep via GitHub issues about their project, and Sweep will generate the code and send a GitHub pull request that the developer can edit and refine. This process saves developers time and energy, especially on mundane tasks that can be automated. Sweep is a YCombinator alum company founded by William Zeng and Kevin Lu, former Roblox employees. The founders recognized large language models' latent code generation capabilities to manage technical debt and address the more immediate issues in bug resolution or feature enhancement. Their vision with Sweep is to liberate human developers to focus on delivering higher value, creative code.
Meet the interviewee
William Zeng, Sweep Co-Founder
William Zeng, the founder of Sweep, formerly served as a Senior Machine Learning Engineer at Roblox, where he was instrumental in developing their first vector search model for game search. Through his month-long project at Roblox, Zeng learned firsthand how complex and time-consuming it can be to set up an application that uses a vector database. This experience led him to search for simpler ways to handle and search through large amounts of code for his next venture, Sweep. In his pursuit, he evaluated various vector databases, including Pinecone, Chroma, and Jina. Eventually, William and his team selected Activeloop's Deep Lake to revamp Sweep's data infrastructure. With its capacity to accommodate multiple collections in memory, intuitive API, and robust synchronization capabilities, Deep Lake offered a simpler and more effective solution to the challenges Zeng encountered during his tenure at Roblox that he didn't want to face ever again.
Activeloop's Deep Lake helped us focus on building the product instead of worrying about scalable data infrastructure. It enabled us to efficiently host multiple collections in memory, overcoming the synchronization issues we faced in our serverless architecture with other vendors. Deep Lake's user-friendly API and low incremental complexity for our product are second to none - it's the perfect fit for tech companies navigating the complexities of Generative AI data infrastructure.

Results Achieved by Sweep with Activeloop
Encountered Challenges: Sweep's Search for An Efficient Data Infrastructure
Before adopting Activeloop's Deep Lake, Sweep tried out multiple vendors like Jina or Chroma but faced several challenges. Since their product is open-source, they wanted to stick to an open-source ephemeral vector database, so Pinecone wasn't a good choice either.
- Lack of efficient data infrastructure: Sweep needed a vector database for its operations, but setting this up took time and effort.
- Inefficient indexing: Sweep needed to host many separate indexes (for one customer, they needed to index and provide context based on 40 repositories), which took a lot of work with their existing setup.
- Synchronization issues: Sweep operates in a serverless architecture and had difficulties synchronizing its operations.
Solution
Activeloop's Deep Lake for AI Code Generation
Activeloop's Deep Lake provided an efficient and scalable data infrastructure solution for Sweep's AI code generation capabilities. It allowed Sweep to host multiple collections in memory, significantly improving their operations' efficiency. Deep Lake also provided an easy-to-use API that made data management more straightforward.

Sync, indexing issues resolution, as well as plug-and-play vector database solution
Activeloop's Deep Lake brought significant improvements to Sweep's operations:
- Plug-and-play data management for Gen AI: Deep Lake enabled Sweep to host multiple collections in memory, which streamlined their operations
- Improved synchronization: With Deep Lake, Sweep overcame synchronization issues in their serverless architecture.
- Reduced complexity from day 1: Deep Lake's intuitive API and effective data handling simplified the processes of Sweep without adding extra layers of complexity.
Concluding remarks
The Way Forward: Sweep's Future Plans in the AI Coding Assistant Domain
Looking ahead, Sweep plans to focus more heavily on its open-source tool and aims to provide more localized services for developers. The team is exploring ways to make the coding process even more efficient by handling mundane tasks such as monitoring graphs, reading logs, and deploying services. Whether handling constant repository changes or managing multiple small indexes, Deep Lake's adaptability, efficiency, and serverless architecture can be instrumental in helping Sweep achieve its future goals.
