Thunders

Market position

Positions itself as an AI-native alternative to script- and selector-based automation frameworks such as Selenium, targeting the software testing market that investor Silicon Badia describes as growing from $87.4 billion in 2024 to a projected $512.3 billion by 2033. The company characterizes its 2025 raise as one of the largest seed rounds in the testing space, and was selected to STATION F's Future 40 2025 (40 startups chosen from over 1,000 on campus).

Intent-based tests authored in natural language rather than code or selectors, combined with self-healing agents intended to survive interface changes; a single platform spanning web, mobile, API and desktop instead of fragmented tooling; and role-based expert personas that extend testing beyond functional checks into SEO, accessibility (WCAG 2.1/RGAA) and security scanning, including customer-defined personas. The company also emphasizes accessibility to non-technical users, deep in-house testing expertise (15+ ISTQB certifications across the team), and repeat founders with a prior exit in the same software category.

Technology

Agentic AI system in which LLM-driven "AI test agents" interpret natural-language intent, generate test steps, execute them across web, mobile, API and desktop surfaces, and self-heal: when a test fails after a UI change, the agent analyzes the new structure and adjusts the scenario rather than relying on fixed selectors. Complementary components include a browser test recorder that captures clicks, inputs and navigation into editable steps, test plan generation from imported requirements, step-level run diagnostics, real-time analytics and usage dashboards, and role-specific expert personas for SEO, accessibility, security, QA, product and DevOps checks. Security and operations claims include SOC 2 compliance, data isolation, audit logging, end-to-end encryption and a 99.9% uptime SLA.

Go-to-market

Direct sales motion built around booked demos and expert calls plus a self-serve free trial, supported by content marketing (company blog, articles on agentic testing and regression automation) and founder thought leadership. Distribution and credibility channels include a Microsoft Azure Marketplace listing, selection into Microsoft GenAI Studio, Meta and Allianz accelerator programs, a presence at VivaTech, and STATION F's Future 40. Partners such as B/Acceptance run proofs of concept with Thunders when validating technologies for their own clients, indicating a partner/reseller channel alongside direct sales.

QA, DevOps, engineering and product teams at software organizations, including non-technical roles such as product managers who write test plans in plain language. Named customers and reference users include LegalPlace, Infopro Digital, agorapulse and consultancy B/Acceptance, spanning SaaS, fintech and B2C platforms. The platform is also positioned for enterprise buyers requiring compliance, security and coverage guarantees.

Geography

Headquartered and built between Paris, France and Tunis, Tunisia, with a remote-first culture spanning five countries. Reported commercial validation across the United States, Canada, France and Tunisia, and stated plans for European expansion plus longer-term expansion in Europe and North America.

History

Concept developed in late 2024 by Karim Jouini and Jihed Othmani. The company was founded in January 2025 between Paris and Tunis; in Q1 2025 it launched an MVP, was listed on the Microsoft Azure Marketplace and was selected for Microsoft GenAI Studio. Q2 2025 brought first paying clients, a VivaTech presence, a $9M seed round and market validation across the US, Canada, France and Tunisia. In Q3 2025 the team passed 15 employees across Paris and Tunis, the company renamed itself from Thunder Code to Thunders, and a new website and publicly accessible platform launched. Q4 2025 additions included selection to STATION F's Future 40 2025, the Meta Accelerator Program, the Allianz Accelerator Program, and an "Entreprise IA de l'année 2025" recognition. The stated Q1 2026 focus is European expansion and building out mobile, desktop and API testing.

Risks & controversies

Performance figures such as 10x faster testing, 88% less maintenance, up to 90% reduction in testing time and the 80% coverage and 100-test customer results are company-stated and not independently verified in the available material. Several headline platform surfaces (mobile, desktop, API) appear on the site while the company's own timeline lists these capabilities as still under development, and features including scheduled runs, one-click documentation and email testing are marked as forthcoming. The company is early stage, founded in 2025, and operates in a testing market with established script-based automation incumbents.
