About Thunder Code

Thunders envisions a future where software quality assurance is universally accessible, removing technical barriers and empowering every stakeholder in the software development lifecycle. We exist to transform how software is tested by harnessing sophisticated AI to automate complex testing tasks efficiently and reliably.

Driven by agentic AI technology, our platform autonomously generates, executes, and self-heals tests, unlocking unprecedented speed and accuracy in software quality processes. Through innovative architecture and seamless no-code interfaces, we make rigorous testing intuitive, inclusive, and scalable for all teams.

By democratizing test automation beyond traditional technical roles, Thunders is building the foundation for a world where software releases are faster, safer, and more predictable—accelerating innovation across industries with confidence and ease.

Our Review

We've been tracking Thunders since their quiet launch in late 2023, and honestly? We're impressed by how quickly they've moved from idea to execution. This AI-powered testing startup isn't just another "AI will solve everything" company — they're tackling a real pain point that every software team knows too well.

The No-Code Promise That Actually Delivers

What caught our attention first was Thunders' bold claim about democratizing software testing. Most testing tools still require serious technical chops, but their AI agents genuinely write, run, and monitor tests without code. We've seen too many "no-code" platforms that still feel like coding in disguise, so this approach feels refreshingly different.

The platform's layered architecture is smart — it converts natural language into test scripts, then uses AI agents to execute everything automatically. Even better, it self-heals when UI elements change, which could save teams countless hours of maintenance.

Founders Who've Been There Before

Here's what gives us confidence: Karim Jouini and Jihed Othmani aren't first-time founders throwing around AI buzzwords. They successfully exited their previous company, Expensya, for $120 million. That track record matters, especially when you're promising to revolutionize an established market like software testing.

The fact that they went from founding to $9 million in seed funding within six months tells us investors see the same potential we do.

Room to Grow Into Something Bigger

Right now, Thunders focuses on web testing, but their roadmap includes mobile, desktop, and API testing by late 2025. That's ambitious but realistic given their foundation. The rebrand from "Thunder Code" to just "Thunders" signals they're thinking beyond technical users — they want product managers and business teams using this too.

For teams drowning in manual testing or struggling with flaky automated tests, Thunders could be exactly what they need. We're excited to see how they execute on their expansion plans.

Bio

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. Founded in 2025 and based at Station F in Paris. Backed by Silicon Badia and Janngo Capital. Start testing at thunders.ai
