Company profile

researched Aug 2026

nunu.ai, operating under the legal entity Generai AG, develops multimodal AI agents that interact with games and applications the way a human tester would — observing the screen and acting through touch, keyboard or mouse — in order to automate quality assurance and related tasks. Users describe what they want done in plain English without writing code; agents execute end-to-end tasks such as completing tutorials, flagging likely bugs, running purchase flows, giving feedback on onboarding, conducting competitor analysis or drafting level design documents, and results are surfaced in dashboards and detailed reports in real time.

The platform, called Nexus, covers test authoring (verification, discovery and task-agent testing), multiplayer scenarios where several agents communicate and collaborate, build storage, deployment configurations, triggers for scheduled or build-based test runs, CI/CD integrations (GitHub Actions, GitLab, Jenkins, TeamCity, Applivery), TestRail export, an API and an MCP integration. An optional NunuSDK for Unity and Unreal Engine 5 exposes game state, in-engine functions, exception logging and performance tracking for deeper integration. Agents run on PC and mobile (iOS and Android), with console support described as coming soon, on infrastructure the company hosts on consumer hardware.

The company frames its agents as "Unembodied Minds" — systems intended to control any given body and perform any task in any environment — and states an ambition to extend from virtual environments into real-world robotics, having experimentally ported its stack onto a quadruped robot.

Founding story

Jan Schnyder, Kyrill Hux and Nicolas Muntwyler met in 2017 during a lecture at ETH Zurich and founded nunu.ai in 2022. As students they built generai.art, described as Switzerland's first image generator, which helped secure acceptance into Y Combinator; the founders subsequently dropped out to work on the company full time.

Business model

B2B software platform sold to game and app developers, providing hosted AI agents and dedicated infrastructure for automated testing; the company markets no-integration onboarding with an optional SDK for deeper engine integration.

Traction

Following launch, gaming studios of various sizes have deployed the agents to QA-test their titles, running hundreds of automated tests monthly on a 24/7 basis. Demonstrations include an agent completing the tutorial of Hogwarts Legacy from simple instructions, and the company's agents have been reported to set multiple in-game world records in titles including Pokémon Emerald and Hogwarts Legacy. The company states it is SOC 2 compliant.

Latest developments

The seed proceeds are being used to recruit talent, expand infrastructure and build out video game QA automation. The company has signalled expansion beyond virtual environments, arguing that game engines are becoming advanced physics engines and that its agents could transfer to real-world settings; an experiment ported the stack onto a quadruped robot for physical retrieval tasks. Console support for agent execution is described as forthcoming, alongside bot detection capability noted in 2024 coverage.

Full profile — market position, technology, go-to-market, geography, history

Market position

Positions itself as building the first multimodal agents to play and test games, addressing QA spend that the company says accounts for roughly 10% of game development budgets and is typically handled by manual testing or brittle automation scripts that break on game updates. Backers include a16z speedrun, TIRTA Ventures and Y Combinator.

Generalizability across titles without retraining, interpretability (agents generate reports and explain decisions), real-time interactability with the agents, script-free maintenance, multi-agent multiplayer testing, and a human-like device interface enabling black-box testing across PC and mobile.

Technology

Large multimodal models drive agents that perceive the screen and act through human input devices, giving a black-box testing approach that the company says generalizes across games with minimal retraining, explains its own actions and decisions, and adapts to game changes without script maintenance. Supporting technology includes the Nexus platform, build storage, triggers, an API, and the NunuSDK with Flayer functions, game state access, EldritchLink, exception logging and performance tracking for Unity and Unreal Engine 5.

Go-to-market

Direct sales to game studios via self-serve sign-up ("get started") and sales contact ("talk to us"), supported by developer documentation, CI/CD and TestRail integrations, and public demonstrations of agents playing commercial titles. Y Combinator network introductions to game studios were explicitly solicited in the company's launch post.

Game studios of varying size and app developers needing QA automation — smoke, regression, compliance and exploratory testing — plus use cases in market research and compliance checks.

Geography

Headquartered in Switzerland; the company (Generai AG) is based in Vorderthal, Canton Schwyz, with founders originating from ETH Zurich.

History

Founded in 2022 in Switzerland, the company joined Y Combinator's Winter 2023 batch and publicly launched agents to play and test games. It raised a $2 million pre-seed round reported in August 2024 and a $6 million seed round announced on 14 March 2025, co-led by a16z speedrun and TIRTA Ventures with Y Combinator participating, bringing total capital raised to $8 million. Platform documentation was last updated in May 2025.
