GitLab

YCombinator

A complete DevOps platform delivered as a single application.

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.

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.

GiveMeTap is a social enterprise. Our mission is to make clean drinking water available to everyone, everywhere. We create stainless steel water bottles, and each bottle funds 5 years of clean water for someone in Africa. When you get a GiveMeTap bottle, you also have access to the free-water network of cafes and shops who give free tap water to people on the go. No questions, no hassle. We build water projects in remote villages and elect a water committee to run the maintenance of the water. So far we have made an impact in Namibia, Malawi, and Ghana to bring clean water for the first time. We like to think of this as ‘Water for You, Water for Everyone’. We help awesome companies create custom bottles for their staff, customers, and events so that they can stay hydrated, reduce plastic waste and help fund water projects.

Glen

YCombinator

Unified organizational context for agents and humans

Glen is unified context for every agent and human on your team. Most MCP tools hand an agent a slice, one Slack thread, a single diff, and leave it to stitch the rest together itself. Glen reads from where your work already lives, code and PRs, issues, docs, and meetings, reconciles it, and gives your agents the full picture instead. With Glen a coding agent knows why a line was written, not just what it says. Ask a PR assistant anything about a change and the clarifying-question relay disappears. Bug bots read the intent behind the code before they comment, so they stop flagging deliberate choices as defects and stop repeating mistakes they already made. A sales agent can coach your head of sales off the full account history, how teammates handle similar calls, what was promised, where the deal stalled, etc. As the work gets done, Glen also distills it into skills and offers them back to the next agent, or person, who hits the same task.

Glue

YCombinator

The Interface Design Canvas for AI agents

Glue is an open source design editor for AI agents. It gives coding agents an infinite canvas to create new interfaces, iterate on existing ones, and turn those changes into production-ready code all in real time. The rise of coding agents is collapsing EPD into one role: builders. This new paradigm means design and engineering can now converge to a single workflow. Builders no longer want static mockups in one tool, and implementation in another. Glue is a collaborative workspace where builders and agents can create new components, iterate on existing interfaces, and implement as code. The same tight feedback loop that once made Figma powerful for designers is now built for builders and their armies of agents. Being open source allows us to penetrate workflows at zero cost and build trust quickly. Right now there are no design tools with AI as the primary user. Existing tools bolt on copilots as an afterthought. Soon, every company will have AI agents building their interfaces. We are building the surface for this workflow.
