The AI graveyard: a running list of projects and startups that didn’t make it

Relay, an AI-powered workflow automation tool built as an alternative to Zapier, shut down entirely on Monday. The product let users automate email and task workflows using AI agents, but as OpenAI, Google, and other larger platforms built similar automation directly into their own tools, five-year-old Relay struggled to hold onto a reason to exist as a standalone product.

Relay’s story — a startup outpaced by bigger platforms — is one version of the story playing out right now. But plenty of AI bets never even survive inside the companies that build them. According to S&P Global Market Intelligence , about 42% of AI initiatives are ultimately abandoned by their corporate parents. The reasons vary: insufficient funding, technical challenges, competition, difficulty scaling, or just weak user demand.
