Shows how much more likely Stoplight.io customers are to use each tool compared to the general population. For example, 287x means customers are 287 times more likely to use that tool.
I noticed that Stoplight.io users are API-first B2B SaaS companies with sophisticated developer tools and a strong focus on product quality and customer experience. The presence of tools like SonarQube Cloud and Drata alongside customer success platforms like Gainsight tells me these are growth-stage companies building developer infrastructure or platforms where API reliability is mission-critical to their business model.
The pairing of Stoplight with Atlassian StatusPage makes perfect sense for companies whose APIs are their product. When your customers depend on your API uptime, you need both excellent documentation (Stoplight) and transparent incident communication (StatusPage). The correlation with Amplitude is equally revealing. These companies are measuring how developers interact with their APIs as a product experience, treating API adoption like user engagement. The Gainsight connection confirms they're running enterprise sales motions with high-touch customer success, likely because their contracts are substantial and retention depends on successful API integration.
My analysis shows these are primarily product-led growth companies that have evolved into hybrid sales models. They attract developers through great documentation and developer experience, then layer on enterprise sales and customer success as deals grow. The Drata correlation suggests they're selling into regulated industries or enterprise buyers who demand SOC 2 compliance. They're probably Series B or later, having graduated from pure PLG to needing formal compliance, customer success operations, and account management. The Reachdesk presence indicates they're running targeted account-based marketing campaigns, likely for enterprise upsell.

I noticed that Stoplight.io's typical customers are platform companies building the infrastructure layer of their industries. These aren't traditional product companies. They're creating API-driven platforms, data gateways, and integration hubs that connect disparate systems. BatchData provides "enterprise-grade APIs" for real estate data. Phyllo builds "the underlying infrastructure that connects with every creator platform." MatchMove offers a "Banking-as-a-Service" platform. They're overwhelmingly B2B companies selling technical infrastructure to other businesses.
These are predominantly growth-stage companies, not early startups or Fortune 500s. The employee counts cluster between 11 and 200, with most in Series A or B funding stages. Many have raised $10-35M, suggesting they've proven product-market fit but are still scaling. Some show impressive metrics in their bios, like Hospitable's "25 million messages" or Swiftly's "190 transit agencies," indicating real traction. Yet few have reached the thousand-employee threshold of mature enterprises.
