The AI Graveyard: Startups and Big-Tech Products That Stalled, Shut Down, or Never Found Their Footing

The AI graveyard is filling up. S&P Global Market Intelligence estimates that about 42% of AI initiatives are abandoned, and the reasons range from funding shortfalls and technical problems to competition, scaling difficulties, and weak demand. The casualties include not only young startups but products from OpenAI, Apple, Microsoft, and Notion, along with hardware from Humane and Rabbit.

Startups that closed their doors

Relay spent five years building workflow automation meant to compete with Zapier. It shut down entirely in August. The company lost ground as OpenAI and Google added similar automation features to their own offerings.

Huxe, an AI audio app from former NotebookLM developers, converted written information into podcast-style audio. It shut down in May 2026, squeezed by competition from larger platforms such as Spotify.

Yupp let users compare responses from hundreds of AI models, vote on them, and earn cryptocurrency. At its peak it tested more than 800 models. It shut down in March 2026, with its founders saying the platform lacked product-market fit.

Figgs AI operated from 2023 to 2024 and let users create customizable AI characters for role-play. It reportedly drew over 1 million users but shut down because running the free service became too costly.

Character.ai: from $1 billion valuation to bankruptcy

Founded in 2021 by Noam Shazeer and Daniel De Freitas, Character.ai raised $150 million at a $1 billion valuation in 2023. Google later paid a reported $2.7 billion to license its technology and brought the founders back into its orbit.

The legal pressure mounted. Families sued Character.ai over teen suicides and self-harm, and Disney sent a cease-and-desist over character use. Late last year the company barred under-18 users from open-ended chats. Character.ai and Google agreed to settle several suits in early 2026.

In early October, Character.ai filed for bankruptcy, citing legal, regulatory, and operational headwinds. Disney offered $20 million as the opening bidder for an IP license. The app remains running during the bankruptcy, and a sale is expected by late November or early December.

OpenAI's shifting product line

OpenAI briefly redesigned ChatGPT into a super app with Chat, Codex, and Work modes, renaming the original interface ChatGPT Classic. After user criticism, it rolled the redesign back.

The standalone browser ChatGPT Atlas shut down on August 9, less than a year after launch, with its features absorbed into ChatGPT. Operator features were folded in as well, and generation increasingly lives inside ChatGPT, reducing DALL-E’s standalone role. The video platform Sora shut down in March 2026 after facing high operating costs and retention problems.

Apple's long road to a new Siri

Apple Intelligence promised an improved Siri in 2024. The release slipped repeatedly, with Apple citing engineering issues and bugs. The company settled for $250 million over iPhone 16 AI marketing claims. Siri AI appeared in the iOS 27 beta in July and rolled out to English-language users this month.

Microsoft Recall's privacy problem

Microsoft announced Recall at Build 2024. The feature periodically screenshots user activity for later search, which drew a privacy and security backlash. Microsoft delayed Recall for nearly a year, and a researcher later built a tool that extracted data captured by the feature.

Notion Mail and the hardware misses

Notion Mail launched in April 2025 and is scheduled to shut down on September 22. Notion found that users preferred separate AI agents for email.

Humane raised $230 million for its AI Pin, then warned customers to stop using the charging case over a fire risk. It shut down the AI Pin business in February 2025, and HP acquired most of its assets for $116 million.

Rabbit unveiled the R1 at CES in January 2024 and said it sold 100,000 units shortly after launch. Early reviews described the device as unfinished. Rabbit continues updating the R1 as a computer controller and announced Project Cyberdeck for portable vibe-coding.

What the failures have in common

The pattern repeats across both startups and large companies: features get absorbed by bigger platforms, legal and regulatory costs mount, free services become too expensive to sustain, and products arrive before they are ready. Abandonment is not rare in AI. It is routine.
