The Problem

Engineering teams at large companies spend about 50% of their time on codebase maintenance including migrations and upgrades. Even worse, many organizations are so far behind on modernizing their technology stacks that they have become paralyzed and unable to move forward.

Our Vision and Mission

Here at Second, we see a future where all engineering grunt work tasks are automated, giving human engineers more space to innovate and create new software. We are on a mission to realize this future by first automating migrations and upgrades for every codebase in the world.

How it Works

Users connect a Second Agent to their GitHub account, select a repository (or use one of our example templates), run a migration module, and get a pull request. It’s that easy!

Each of our modules are hand-built to perform specific migrations, and serve as a high level blueprint or plan. Next, our agents run these modules by utilizing AI, codemods, and other techniques to perform directory restructuring and code changes. Our agents have proprietary codebase scanners, dependency resolvers, and much more. Every migration job is broken up into steps like this:

Why we are Relaunching

Second was in the last batch (W23), but we are relaunching because we have refocused our product on migrations and upgrades only, whereas previously we were focused on commodity web application feature creation. We made this change because it became crystal clear after hundreds of discovery conversations that codebase maintenance is a much bigger pain point for large companies. We are already working with three large enterprises and couldn’t be happier! 😄
