Remember the first time you hit and your code actually worked? Something that didn't exist before, now alive on your screen. Today, coding agents can do that, orders of magnitude faster. But their verification is shallow at best. The faster agents generate code, the wider the gap grows. Nothing verifies software at the speed agents ship code. We believe verification unlocks long-horizon coding agents: agents that run for days and prove their work as they go.

Speedscale helps engineers validate their code with real, sanitized traffic. We simulate realistic production conditions in Kubernetes so you no longer need to manually script or use large and complex environments. Catch performance defects before they reach production and reduce weeks-long test cycles down to a few days.

Coding agents made writing code fast. But 6 engineers in a room will probably still disagree on what needs to be built. Scott AI is a planning workspace where engineering teams align on what to build before their coding agents start building it.

Haystack helps engineering teams manage the growing volume of AI-generated pull requests. Coding agents make it much easier to produce code, but they also create a new problem: teams now have more changes to review, many of them larger, more frequent, and harder to trust at a glance. Haystack sits on top of GitHub and acts as the control layer for AI-generated code changes. For every pull request, it looks at the codebase, the diff, the agent trace, the author’s intent, and any verification evid

Compyle is a less autonomous coding agent that asks before it acts. We're like Cursor or Claude Code - but you won't need to rewrite your codebase every time you use it for more than a small task. We built Compyle because we were frustrated with the direction other coding agents are headed. They're all racing to be more autonomous, running for hours without human input. This doesn't work for real production code. When agents run autonomously, they make countless small decisions that pile up in y

Zillabyte is a cloud platform for data analysis. Build apps, not infrastructure. We set up and maintain the infrastructure you need to analyze your data. All you need to do is develop your app locally and test it using the our CLI. When you need to scale, push to our servers. Easily add more functionality with components, modular code blocks that let you perform additional functions such as: geo coding, fraud analysis, and web scraping. Use your own private datasets or plug into our off-the-shel
