Companies that are listed in the Github Marketplace

Source: Analysis of Linkedin bios of 948 companies that use Github Marketplace

I noticed that GitHub Marketplace users are overwhelmingly software-focused companies building developer tools, security platforms, and automation solutions. These aren't companies that merely use software. They're building products for other developers: AI code review tools, testing platforms, CI/CD integrations, security scanners, and compliance automation. Many are creating layers that sit between developers and their workflows, promising to make existing processes faster, safer, or more intelligent.

These are predominantly early-stage companies. My analysis shows 60-70% have fewer than 50 employees, many listing just 2-10 people. Funding stages cluster around pre-seed and seed, with typical raises between $500K and $8M. Several mention Y Combinator or other accelerators. The handful of larger companies like Postman, Datadog, and JFrog appear to be the exception, not the rule. Many companies have no listed funding at all, suggesting bootstrapped or very early operations.
