Summary

"Seele (全灵)," a game-generation AI startup founded in Shenzhen, China, is drawing attention within Silicon Valley's VC community. CEO Shimu Wang (王詩沐), one of China's leading product talents, has held positions ranging from designer and product manager at Alipay (支付宝), to Vice President of NetEase Cloud Music (網易雲音楽), and General Manager of Tencent News (騰訊新聞). Building on the company's proprietary multimodal large models "Seele01" and "EVA-01," he is constructing an end-to-end platform that generates playable 3D games from natural language in a matter of minutes. This article examines, from multiple angles, Seele AI's technological advantages, Shimu Wang's lesser-known background and reputation within the industry, the company's positioning against competitors such as Astrocade (backed by Sequoia / Sea) and Rosebud AI, and how Silicon Valley VCs view this China-born startup.

What is Seele AI: The world's first MLLM-based platform that generates "playable 3D games" from natural language

Seele AI (Chinese name: Quanling) is a 3D game generation AI startup founded in Shenzhen in November 2022, offering a platform that can generate a fully playable 3D game in its entirety simply by inputting a text prompt. The company positions itself as the "world's first 3D multimodal large language model (MLLM)," distinguished by its end-to-end generation of characters, environments, game mechanics, textures, sounds, and even code.

SeeleAgent, available on the official site "seeles.ai," is billed as a "game-native harness agent" purpose-built for game development, integrating file management, preview, chat with the agent, and a game execution runtime into a single workspace. Generated games can be playtested immediately in the browser, exported as clean C# projects in Unity 6 format, or distributed on the web via Three.js. Export to Unreal Engine 5 is also slated to launch in Q2 2026, and once implemented, the company claims it will become "the world's only AI game generation platform spanning all three engines—Unity, Unreal, and Three.js."

Game genres cover both 2D and 3D, including major categories such as action, RPG, simulation, puzzle, platformer, and strategy. Multiplayer support is also included as standard. The asset generation engine is designed to deliver 2D sprites and animation frames, 3D models with PBR textures, character rigging, over 5 million animation presets, BGM, sound effects, and voice acting in a one-stop manner, supporting everything from AAA-class 3D assets to retro pixel art.

As a spin-off product, the company also offers "Koko AI," a companion AI that allows face-to-face voice conversations with 3D virtual characters. It leverages Seele's in-house developed 3D multimodal large model "EVA-01," providing an integrated experience of 3D models, animation performances, and voice chat free of charge, aiming to open a new stage in the emotional companion market. As discussed later, Koko also serves Seele as a layer for accumulating high-quality 3D data used to train their flagship "game generation AI."

On the technical foundation side, the company adopts AWS's Amazon Bedrock and Amazon EKS, with Anthropic Claude also integrated via Bedrock. According to the AWS Case Study, Seele achieved "a deep transformation from Infrastructure Migration to Intelligence-Driven Operations" through an agentic AI architecture on AWS, with CEO Shimu Wang himself stating that it "significantly reduces costs while doubling the efficiency of core decision-making." A Show HN comment on Hacker News notes that PhaserJS is used for the rendering layer of the web games, contributing to the lightweight feel of instant browser play.

Growth in the user base has been rapid: 36Kr reported that at the time of the November 2024 funding round, the overseas product had reached approximately 1 million users in half a year; at the time of the December 2025 Sina Finance interview series "100 AI Entrepreneurs," cumulative users exceeded 1 million with over 30,000 games; and as of the official site in May 2026, cumulative creators exceed 366,000 with more than 200,000 games generated. SeeleAgent's monthly active creators have reached over 100,000, and as of the writing of this article, there is also a page promoting "1M+ creators."

Wang Shimu's Background and Education: Graduate of Zhejiang University's Industrial Design Department, His Book "Behind the Product" Rated 8.3 on Douban

Wang Shimu (王詩沐, Shimu Wang) has an unusual background within China's IT industry. He graduated from the Department of Industrial Design (工业设计系) at Zhejiang University, making him a rare product leader who built his foundation in UI/UX and product design through rigorous academic training, rather than coming from a traditional computer science background. Zhejiang University consistently ranks among China's top 5 comprehensive universities, and its Department of Industrial Design is recognized as one of the leading programs in the country in that field.

From his student days, he had a strong interest in "user observation" and "making things," and immediately after graduation, he joined Alipay, a member of the Hangzhou-based Alibaba Group, as a new graduate hire. According to the career databases of IT Juzi and 36Kr, he spent his first year as a designer for Alipay's "Life Assistant (生活助手)" service, gradually expanding his role from UI design to product planning. The rigorous UX sensibilities for "payment and financial products" he cultivated during his Alipay years, along with his feel for "handling services at a scale of hundreds of millions of users," laid the groundwork for the scaling expansion he would later lead at NetEase Cloud Music.

The book Wang Shimu published in 2024, "Behind the Product: Building Breakthrough Product Thinking (幕後產品：打造突破式產品思維)," earned a high rating of 8.3 on the Chinese book review site Douban, and he is recognized within the industry as a theory-oriented product manager. The book systematizes the methodology he distilled from his successful experience at NetEase Cloud Music, covering topics such as "observation of users' deep psychology," "philosophical design of products," and "the back-and-forth movement between intuition and numbers."

Regarding his private life, aside from occasional posts he makes on Zhihu (@shimuuu), publicly available information is extremely limited, and there is virtually no public information about his family or hobbies. However, as Wang himself remarked in a Sina Finance "100 AI Entrepreneurs" interview (December 2025), "I'm less a corporate leader and more an entrepreneur at heart. I should have started my own venture sooner" — repeatedly indicating that he is the type of person more passionate about "building from zero himself" than navigating internal organizational politics.

Career history: From Alipay designer to NetEase Cloud Music VP, to Tencent News GM

Wang Shimu's career truly took off when he joined NetEase in 2012. He participated in the launch project of NetEase Cloud Music as the product lead from the very beginning, having been personally designated by founder William Lei Ding (Ding Lei) to head the service. He set forth two major strategies—"making playlists the core" and strengthening algorithmic recommendations—establishing the brand as "the music app that understands users best." According to an article in the tech media outlet 36Kr, NetEase Cloud Music's monthly active users grew rapidly under Wang Shimu's leadership, reaching 60 million MAU at its peak.

Within NetEase, following the success of the music app, Wang Shimu was also laterally appointed as the head of the cosmetics community app "NetEase Beauty" (Wangyi Meixue). After being promoted to Vice President of NetEase Cloud Music, Wang Shimu nevertheless suddenly left NetEase in 2019 and moved to Tencent. This transfer was a major topic of conversation in China's IT industry at the time.

At Tencent, he led the "Xiaoe Pinpin" project as the head of the Innovation Business Division within PCG (Platform and Content Group). This was a competing product through which Tencent attempted to replicate the social e-commerce approach of the then-rapidly-growing Pinduoduo, leveraging WeChat's social graph to the fullest to lower prices through group purchases among friends. According to reports from EqualOcean, it was spun off as a standalone app and distributed on app stores in May 2021, but it failed to overturn Pinduoduo's first-mover advantage, and according to Pandaily, the service's official shutdown was announced in February 2022.

In the meantime, in August 2021, Wang Shimu was appointed as the "First Person in Charge" (effectively GM/Chief Officer) of Tencent News. According to an article in Yicai Global, Tencent News had undergone a leadership change in response to a sharp drop in advertising revenue in Q1 2021, and Wang Shimu was entrusted with its rebuilding.

However, Wang Shimu's tenure at Tencent News ended unsatisfactorily. According to reports by the South China Morning Post and the Chinese media outlet Guanchao Xinxiaofei, he abruptly pivoted the strategy away from the traditional "deep, original reporting content" route toward an algorithm-driven feed model modeled after ByteDance's Toutiao (Jinri Toutiao). However, this caused existing users to leave while failing to capture a meaningful share of short-form video, and it is said to have created friction with the company's journalist faction, including deputy editor-in-chief Yang Ruichun and renowned host Ma Teng.

In May 2022, Wang Shimu was transferred from GM of Tencent News to PCG's Social Platform and Application Business Unit, where he came to lead Tencent's NFT business "Huanhe (Phantom Core)." However, amid the Chinese authorities' intensifying crackdown on NFTs, Huanhe announced the suspension of its service in August 2022, and about a month later, Wang Shimu himself resigned from Tencent.

Wang Shimu's Persona and Industry Assessment: The "Gravedigger" Criticism and the "Tide of the Times" Defense

Wang Shimu's reputation within the industry is sharply polarized. On the positive side, his track record of growing NetEase Cloud Music to 60 million MAU is overwhelming, and he is regarded as a product manager who earned the personal trust of Ding Lei, as well as a product evangelist who combines theory and practice—as evidenced by the 8.3 Douban rating of his book "Behind the Product" (幕後產品). Investors including Meitu, Fukun Venture Capital (風物資本), and Webtime Information S&T have also expressed strong confidence in "Wang Shimu's understanding of AI technology and his ability to apply it to gaming and virtual scenes" when committing to the Pre-A round in Seele AI.

On the other hand, the negative assessments are sharp. The Chinese commentary site 36Kr and Tencent News' own article "Tencent News' 'Gravedigger' Wang Shimu Reborn: Launching a 2D-Anime AIGC Startup?" (騰訊新聞『掘墓人』王詩沐重生：開啟二次元AIGC創業？) have featured comments mocking him as the "gravedigger" (掘墓人) of Tencent News. Critics point out that the three products Wang Shimu worked on at Tencent—Xiao'e Pinpin (小鵝拼拼), the Tencent News overhaul, and Huanhe (幻核)—"got worse as they progressed." At Tencent News in particular, veterans of the editorial front lines such as Yang Ruichun and Ma Teng pushed back against "putting numerical KPIs above content quality," and there is even an anecdote that Ma Teng complained to Zhang Xiaolong (the Zhang Xiaolong famous as the founder of WeChat) that he had "been subjected to insulting verbal abuse by Wang Shimu."

Defenders emphasize the magnitude of external factors, arguing that "traditional news portals were structurally finished under ByteDance's Toutiao offensive" and that "Huanhe was a victim of NFT regulation." In a late-2025 interview with Sina Finance, Wang Shimu himself looked back, saying "Xiao'e Pinpin and Huanhe were not failures but strategic exploration. Decision-making at a large enterprise operates on a different dimension from the success or failure of a single product"—not entirely denying his own responsibility, but also calmly analyzing the structural limits at the organizational layer. In the same interview, he also stated: "I want to reject the very label of 'product manager.' Unless you are someone who cuts across algorithms, architecture, business, and technical depth all at once, you cannot build products for the AI era"—a remark that suggests the depth of his hands-on involvement at Seele.

All in all, Wang Shimu is a complex figure who carries both sides—"the legend of NetEase Cloud Music" and "the losing streak at Tencent"—and the investment decision in Seele AI takes on a strong character of a bet on "the original product capability he is likely to demonstrate once freed from the constraints of organizational politics."

How Seele AI Differs from Other AIs: The Trifecta of MLLM-Native, End-to-End, and Cross-Three-Engine

While many services are lumped together under the label of "game AI," Seele AI has three clear points of differentiation.

First, Seele AI does not "have a general-purpose LLM write games" — rather, it optimizes its in-house multimodal large-scale models "Seele01," "EVA-01," and "4D World Model (coming soon)" specifically for game generation, which is a decisive difference. There are many services that have OpenAI's GPT or Anthropic's Claude write game code, but because those are not models trained on 3D spatial consistency, physics, or animation rigging, the sense of scale in 3D scenes and the anatomical consistency of characters tend to break down easily. To address this problem, Seele has separately set up a "data collection infrastructure" that accumulates user-generated data through a 3D virtual character app called Koko, taking a vertical integration strategy of reproducing training data for 3D-specialized models internally. In an interview with Sina Finance, Wang Shimu himself stated clearly that "Koko is an intermediate tool, intended to solve internally the fatal bottleneck of insufficient high-quality 3D training data."

Second, the end-to-end completeness is one level deeper than rivals. Many AI game generation tools tend to lean toward either "asset generation" (images, 3D models) or "code generation," but Seele AI bundles and outputs code, 3D models, PBR textures, character rigging, more than 5 million animation presets, BGM, sound effects, and voice acting from a single prompt. In a Show HN post on Hacker News, one developer evaluated it saying, "Got far better results than when I tried with Claude Code. Was able to generate an RPG," and the Phaser.js-based instant-execution-in-Web and the high quality of the code have been favorably received.

Third, support for exporting to game engines is broad. Seele AI's 3D games can currently be exported to Unity 6 and Three.js (Web), with Unreal Engine 5 support scheduled to be added in Q2 2026. With this, the plan is to cover all major platforms: mobile, Web, desktop, and console. Creators can either receive revenue share within the Seele platform (80% returned from advertising, play-time linked revenue, and in-app purchases), or sell independently on Steam, the App Store, or Google Play.

However, several weaknesses have also been pointed out for Seele AI. According to the Hacker News developer community and comments from Seele's own development team, the constraint that "handling complex 3D spatial relationships is a weak point" remains, and breakdowns can be seen in intricate dungeons and high-density open worlds. In the Sina Finance interview, Wang Shimu self-evaluated the current game model capability as "L1 stage," describing "simple games at the Flappy Bird class" as the present limit, with "Animal Crossing: New Horizons"-level complexity within 2026, and fully immersive worlds in 2029 — drawing a long-term staircase. While this is an honest progress report, it also means he is sharing with investors the sober recognition that, at present, it is far from being a replacement for AAA titles.

On the business side, the plan is to transition from the current subscription-billing model to a creator advertising revenue-share model in the future. He stated that "asset reusability is the key to cost," and explained that unlike formats such as image/video generation where new computation is required for each output, in games, similar architectures are reused repeatedly, so marginal costs can be compressed down to "single-digit dollar units." This is designed with awareness of maintaining SaaS-level gross margin ratios, as a point of persuasion for investors.

Silicon Valley VC Perspectives and Media Coverage: Cautious Optimism Toward Baidu-Backed Chinese Startups

Direct investment participation by Silicon Valley VCs in Seele AI has not been confirmed on an official disclosure basis as of the time of this article's writing (May 2026). The Pre-A round was led by Baidu Strategic Investment (百度战略投资), with co-investors comprising Chinese VCs including Meitu Investment (美图投资), Fukun Venture Capital (風物資本), and existing shareholder Webtime Information S&T. Major Chinese media outlets such as Sina Finance, Sina Tech, and 36Kr reported on the round, framing it as "Baidu solidifying its position in the China AIGC × gaming space."

Meanwhile, Bloomberg's exclusive article dated May 28, 2025, "Baidu-Backed AI 3D Game Creator Seele Seeks New Funding," reported that Seele is exploring a new post-Pre-A round at "a valuation of several hundred million dollars (approximately several tens of billions of yen)." This article was widely circulated within the Western VC community and served as a signal that Seele is targeting not only the Chinese market but also global investors. English-language tech media such as Pulse24, ainvest.com, and opentools.ai also cited the article, introducing Seele as the "Baidu-backed AI 3D game creator."

The most useful reference point for understanding Seele AI's positioning from a Silicon Valley VC perspective is Astrocade, which on May 5, 2026, raised a combined $56 million (approximately ¥8.85 billion at $1 = ¥158) in a Series B and Series A led respectively by Sequoia Capital and Sea. In an interview reported by Fortune, Sequoia Capital partner David Cahn stated, "Women aged 20 to 40 are our best users," and "This is a platform that competes with Instagram—a consumer activity that transcends conventional gaming," positioning the AI game generation space as "less a story about the gaming industry and more a touchstone for the entire AI creative platform category." Astrocade's co-investors include Google, Nvidia, LG Ventures, Dentsu Ventures, and Conviction Embed—a purely Silicon Valley-style lineup.

At eight months post-launch, Astrocade has demonstrated traction of 5 million monthly MAU, 140M plays per month, and 75,000 games across 80 countries, putting it ahead in scale at this point compared to Seele's cumulative 1 million–360,000 MAU and 200,000 games. However, Seele has its own technical defensive moats—"proprietary 3D MLLM," "cross-engine support across Unity, Unreal, and Three.js," and "vertically integrated data collection via Koko AI"—and from the perspective of Silicon Valley VCs, the matchup is being observed as "Seele, leveraging product differentiation and the advantage of Chinese engineering labor costs," vs. "Astrocade, with mainstream U.S. consumer-acquisition strength."

Taking a broad view of the 2026 VC environment, gaming VC overall is in a chill. According to a March 2026 analysis by VC Cafe, VC investment in gaming is down 77% from its peak and 28% even compared to pre-pandemic levels, shrinking to just $627 million (approximately ¥99.1 billion at $1 = ¥158) in the first half of 2025 (versus $2.82 billion, approximately ¥445.5 billion, for full-year 2023). On the other hand, capital is concentrating in the AI game tech space: in Q3 2025 alone, total fundraising by gaming startups reached $1 billion (approximately ¥158 billion), of which roughly $230 million (approximately ¥36.3 billion) was poured into AI Gametech areas such as AI foundation models, voice technology, automated QA, and asset generation. AlixPartners' 2026 forecast report analyzes that "studios combining IP with advanced AI will command a 2–3x valuation premium," suggesting that if Seele can leverage relationships with Chinese and Japanese IP holders (Tencent, NetEase, Meitu, etc.), it could become an asset that Western VCs cannot ignore.

Competitive Service Comparison: Positioning Against Astrocade, Rosebud AI, and Spawn.co

The three companies most frequently cited by U.S. media and analysts as Seele's most direct competitors are Astrocade, Rosebud AI, and Spawn.co.

Astrocade (San Francisco, USA), as mentioned above, is the largest of the three, having secured a total of $56 million (approximately ¥8.85 billion) in funding led by Sequoia Capital and Sea. It is a social-game × AI-generation hybrid player praised by Sequoia partner Cahn as "resonating strongly with women in their 20s to 40s." Its creator-economy model aspires to a YouTube-style structure, openly declaring that "top creators earn several thousand dollars per month," and its investor lineup—including Google, Nvidia, LG Ventures, Dentsu Ventures, and Conviction Embed—is distinctly global.

Rosebud AI (USA) is known for having AI research luminaries Andrej Karpathy and Ilya Sutskever as angel investors, and it holds a position among the market leaders in brand power as a no-code AI game maker. As of 2026, it has evolved from simple asset generation into a full-featured AI game-maker platform, and on comparison sites such as Slashdot it is frequently listed as a direct alternative to Seele AI.

Spawn.co (USA) is comparable to Rosebud AI—an AI-native game-creation platform targeting no-code and casual creators.

While Seele AI lags behind Astrocade in live-platform scale, it holds the potential to stay one step ahead of the other three in the depth of its in-house MLLM technology (Seele01, EVA-01, 4D World Model) and its multi-engine support (Unity, Unreal, Three.js). In particular, whereas Astrocade specializes in consumption experiences on its proprietary platform, Seele intentionally preserves the flexibility of "exporting to Unity and Unreal so that professional game studios can repurpose the output," leaving substantial room for B2B expansion. This is a strategy consistent with Seele's self-definition of tackling—alongside Midjourney (images), Runway (video), and Lovable (web apps)—"the most difficult creative problem: a completable game."

Its relationship with Roblox as a mega-platform is also of interest. Roblox is the king of user-generated content (UGC) platforms, with combined creator-economy payouts together with Fortnite reportedly exceeding $1.5 billion (approximately ¥237 billion) in 2025, and a path is emerging for Seele to coexist with Roblox by plugging into the upper layer (generative-assistance AI) of this massive UGC market.

Future Roadmap and Market Trends: From L1 to L3, the Battle for Leadership in the 3D Era

The roadmap Wang Shimu laid out in his December 2025 interview with Sina Finance is clear. Seele's current game model sits at the "L1 (Flappy Bird-class simple games)" stage, but it aims to reach simulation-game complexity on the level of "Animal Crossing: New Horizons" (equivalent to L2) during 2026. The ultimate goal — a "fully immersive virtual world (L3)" — is set for 2029, articulating the vision that "3D is the next content medium after video, and strong interactivity will be the decisive differentiator."

As for the most immediate confirmed roadmap item, an Unreal Engine 5 support launch is scheduled for Q2 2026. This is expected to complete a "triple-engine architecture" that covers all three layers: Unity's mobile and web market, Three.js's instant browser market, and Unreal's AAA console and PC market. In addition, the "end-to-end AI model for users with no coding experience" that Wang Shimu mentioned in his Bloomberg interview was originally slated for release in July 2025, but its implementation scope is being expanded in stages heading into 2026.

On the funding front, Seele is exploring a new round at a valuation of several hundred million dollars (as of the May 2025 Bloomberg report), and whether Silicon Valley VCs will participate directly will be the single biggest thing to watch over the next 12 months. The investment climate for AI gametech, in contrast to the overall chill across gaming VC, has seen a concentration of capital (as noted earlier: of the $1 billion ≈ ¥158 billion in gaming-related funding in Q3 2025, $230 million ≈ ¥36.3 billion went to AI gametech), and the premium valuations attached to AI are being maintained at healthy levels.

The outlook for market size is bullish, with several research firms publishing forecasts that span a wide range. InsightAce Analytic projects rapid growth from $4.54 billion (about ¥717.3 billion) in 2025 to $81.19 billion (about ¥12.8 trillion, CAGR 33.57%) in 2035, while Precedence Research forecasts growth from $1.5 billion (about ¥237 billion) in 2024 to $9.8 billion (about ¥1.55 trillion, CAGR 20.8%) in 2034. The figures vary significantly across sources, but there is consensus that AI gaming will expand at a CAGR in the high double digits to low triple digits, and for Seele as well, market expansion over the next 5 to 10 years will provide a strong tailwind.

The medium- to long-term risks come down to three: (1) the possibility that Chinese regulators' generative-AI guidelines or cross-border data regulations could impose unforeseen constraints on Seele's expansion into Western markets; (2) the possibility that Western competitors such as Astrocade, Rosebud AI, and Spawn.co will get ahead with larger pools of capital and Silicon Valley talent; and (3) the possibility that Roblox and incumbent game-engine giants (Unity, Unreal) will integrate equivalent AI features and erode Seele's differentiation. On the other hand, Seele also holds three powerful assets: the network within China's IT industry that Wang Shimu built by working across the country's three major IT firms — Tencent, NetEase, and Alibaba; the technical depth of its in-house MLLM; and Western cloud-native operations via AWS Bedrock. Its moves over the next 12 to 24 months will serve as a litmus test of whether a "China-born, genuinely global AI game company" can emerge.
