Thunders employee Safia Mimoun is described as Fractional CMO for B2B SaaS companies.

Thunders is an AI-native software testing platform. Autonomous agents write, run, and maintain your tests in natural language, so your team keeps reliable coverage without the scripts and constant upkeep that traditional automation demands. The old model is brittle: broken selectors, flaky runs, tests that need a dedicated engineer just to stay alive. Thunders replaces it. Describe what you want to test in natural language, and agents handle it across web, mobile, API, and enterprise applications like SAP. We build across four missions: Test authoring: If it runs, our agents can test it. Any tech, any element, from natural language or your existing sources. Test execution: One test or ten thousand, easy to run, on demand or inside your pipeline. Test management: Easy to organise, safe to change. Your suite stays clean as your app grows. Reporting, analytics, and debugging: Whatever the failure, Thunders tells you why it broke and how to fix it. Any test, any run. Natural language is where intent and wording drift apart, and that gap is where tests break. Thunders catches it before and after every run, so you are not the one fixing it, now or later.
