Founding Sales Leader (US) – AI SaaS

About

Thunders is an agentic solution for automated testing in natural language.
Founded in January 2025, we’ve already raised $9M to accelerate our mission : making software testing faster, smarter, and effortless.

Our fast-growing team of 25+ people brings together experts in AI, product, and quality engineering to reinvent how testing is done.

Today, testing is still one of the biggest bottlenecks in software delivery. With the rise of AI-generated code, test volumes are exploding yet testing remains slow, fragile, and often disconnected from what really matters to the business.

Thunders changes the game.
Our solution automatically generates and runs test plans in natural language, powered by specialized agents (UX, performance, accessibility, SEO…).
The result: autonomous, intelligent tests that adapt to your product and keep up with your pace.
