  • GitLab
    GitLab (w2015)Public • 2,000 employees • San Francisco, CA, USA
    GitLab is the first single application for the entire DevOps lifecycle. Only GitLab enables Concurrent DevOps, unlocking organizations from the constraints of today’s toolchain. GitLab provides unmatched visibility, radical new levels of efficiency and comprehensive governance to significantly compress the time between planning a change and monitoring its effect. This makes the software lifecycle 200% faster, radically improving the speed of business. GitLab and Concurrent DevOps collapses cycle times by driving higher efficiency across all stages of the software development lifecycle. For the first time, Product, Development, QA, Security, and Operations teams can work concurrently in a single application. There’s no need to integrate and synchronize tools, or waste time waiting for handoffs. Everyone contributes to a single conversation, instead of managing multiple threads across disparate tools. And only GitLab gives teams complete visibility across the lifecycle with a single, trusted source of data to simplify troubleshooting and drive accountability. All activity is governed by consistent controls, making security and compliance first-class citizens instead of an afterthought. Built on Open Source, GitLab leverages the community contributions of thousands of developers and millions of users to continuously deliver new DevOps innovations. More than 100,000 organizations from startups to global enterprise organizations, including Ticketmaster, Jaguar Land Rover, NASDAQ, Dish Network and Comcast trust GitLab to deliver great software at new speeds.

    Sage AI (w2023)Active • 2 employees • San Francisco, CA, USA
    Sage is a self-generating, self-maintaining knowledge base for your code with in-built chat, accelerating expertise, and comprehension of any codebase. Documentation is perpetually stale, codebases become increasingly old, large, and complex, and knowledge remains siloed within individuals and teams. As a result, engineers take 8-12 months to become fully operational, enterprise code becomes slow and unmaintainable, and core knowledge is continually lost upon engineer turnover. Sage is changing this reality. We take your code and automatically generate a symbol-level knowledge base that self-updates to remain forever fresh. We integrate with source control to pull your code and generate a symbolic graph representation of functions, classes, interfaces, types, etc., automatically determining the relevant context for each symbol, and using LLMs to annotate and propagate documentation via traversals of the symbol graph. Sage revolutionizes the way teams and individuals interact with and understand their code, ensuring that knowledge is always accessible, up-to-date, and interactive.

    Draftaid (w2024)Active • 3 employees • Toronto, ON, Canada
    DraftAid is the world's first generative AI for CAD manufacturing drawings, akin to GitHub Copilot but for CAD. It drastically shortens drawing creation time, turning hours into seconds. Every product that is manufactured - from construction to aerospace, automotive, durable goods, and electronics—relies on drawings. Currently, engineers and designers painstakingly make these essential drawings manually. Draftaid streamlines this process saving teams millions in time and quality. The idea was born out of Abdullah's experience as a mechanical design team member, where he created thousands of drawings and longed for a more efficient process. Partnering with Tahsin, a neighbour with a PhD in AI, and Mohammed, a seasoned engineering VP with experience in construction software, they turned the dream into reality. Since their launch in August, DraftAid has engaged customers through targeted outreach and word-of-mouth, securing paid pilots with subsequent contracts valued at $150,000. Be a part of ushering in the new era of CAD designs!

    BotCity (w2022)Active • 18 employees • San Francisco, CA, USA
    The rise of Robotic Process Automation offered a promise that any business user can build automations. We were skeptical about that and decided to talk to users of platforms such as UiPath, Automation Anywhere, and Blueprism, all of them low-code. Talking to users, we discovered that unique automations incorporating exclusive company processes and intelligence that have the potential to transform the business must be implemented by tech teams. It's not about mimicking employees performing isolated tasks. It's about designing a new workflow, integrated with the company's technological stack and systems. There are just 100.000 RPA skilled users compared to 22M developers globally that can become RPA coders on Day 1 with BotCity. We believe that all automation efforts in a single platform is more efficient. We started delivering the best RPA experience for tech teams, but we envision creating the perfect place to also manage crawlers, integrations, scrappers, data operations. Every company automation in a single place. As companies are becoming tech first and automation will be a basic KPI, we are building to be the all-in-one automation ops management.

Ellipsis runs in the cloud so developers can make progress on other tasks while Ellipsis answers questions, writes code, and conducts code reviews on their behalf. The product integrates with GitHub, Slack, Linear, and other sources, allowing for thoughtful responses that consider the product roadmap, production logs, and bug reports. Our goal is for human engineers to spend more time reviewing code that Ellipsis writes, than writing code themselves. The team launched automatic code review in January and has grown to 30+ customers, with 75% of revenue coming from outside of the W24 batch.
