About Speedscale

Speedscale, founded in 2020, is a promising player in the API and Information Technology sectors, emphasizing Productivity by automating the stress-testing of APIs. With its headquarters in the United States, the company has developed a unique solution that allows developers to stress-test their APIs using real-world scenarios, eliminating the need for labor-intensive manual scripts.

The solution intelligently leverages K8S traffic to write tests and mocks, facilitating effortless monitoring and prevention of potential production incidents. This capability ensures that latency, regression, and performance metrics are maintained within the desired specifications before deployment.

The recent $9.00M Seed investment led by Correlation Ventures, GroTech Ventures, Tech Square Ventures, Sierra Ventures, CreativeCo Capital, TIE Atlanta, Tom Noonan, and Wally Wang on 01 March 2023 underscores investor confidence in Speedscale's innovative approach and growth potential. This influx of capital positions the company well to capitalize on growing demand in the API testing space.
