    Gleb, Alex, Erez and Simon here – we are building an open-source tool for comparing data within and across databases at any scale. The repo is at https://github.com/datafold/data-diff, and our home page is https://datafold.com/. As a company, Datafold builds tools for data engineers to automate the most tedious and error-prone tasks falling through the cracks of the modern data stack, such as data testing and lineage.

    We're building version control software for Microsoft Office documents that works as well as Git and GitHub do for code. Today, we’re releasing the first component, Draftable for Word, an Office add-in that lets you generate side-by-side diffs, and makes it way less painful to work with Track Changes.

Instead, I thought I’d give it a shot myself (famous last words). I dove into it having no real formal…
