About Quillstack
Quillstack builds developer tooling for API versioning, schema validation, and changelog generation, sold as a set of CLI tools and a lightweight hosted dashboard. Right now around 3,200 engineering teams use Quillstack to catch breaking API changes before they hit production, and our largest customer runs it across more than 400 internal services. We're a twelve-person, fully remote team spread across six time zones, and we ship almost entirely based on GitHub issues filed by our own users. There's no sales team yet, most new customers find us through a blog post or a coworker's recommendation. If you like small teams, terminal-first products, and shipping code the same week you write the spec, this is that kind of place.
