Cue (formerly Greplin) is a personal information management service that helps users organize and make the most of their day by intelligently surfacing relevant information from their email, contacts, calendar, and other online accounts. It builds a unified view of a user’s schedule and communications, offering predictive search and contextual insights to anticipate needs such as upcoming meetings or tasks[1][3]. The product serves individuals seeking to streamline their digital lives by reducing the manual effort of managing multiple information sources and calendars.
Founded by Daniel Gross and Robby Walker, Cue originated as Greplin, a personal search engine launched through Y Combinator in 2010. The founders aimed to create a "Google for your personal life," enabling users to search across various online services from one interface[1][2]. Over time, the focus shifted toward predictive search and automated calendar management, evolving into Cue. The company raised significant venture capital, including $4.7 million in 2011 and an additional $10 million in 2012, before being acquired by Apple in 2013 for an estimated $40 to $60 million[2][4][5]. After the acquisition, Cue was integrated into Apple’s ecosystem, and the standalone service was discontinued.
Core Differentiators
- Predictive Search and Contextual Awareness: Cue’s technology anticipates user needs by surfacing relevant information before the user explicitly searches, such as upcoming meetings or contacts[1][4].
- Unified Personal Data Search: Unlike traditional search engines, Cue indexed personal data across multiple platforms (email, social media, cloud storage) in one place[1][2].
- Freemium Model: Most users accessed Cue for free, with premium features available for business accounts integrating services like Salesforce and Yammer[1].
- Strong Founding Team: Daniel Gross, a young prodigy with a background in AI and machine learning, and Robby Walker, a highly accomplished technologist, brought deep technical expertise[1][2].
Role in the Broader Tech Landscape
Cue rode the wave of increasing digital information fragmentation and the growing need for personal productivity tools that leverage artificial intelligence. The timing was crucial as mobile devices became central to daily life, and users demanded smarter, context-aware applications that reduce cognitive load. Cue’s technology anticipated the rise of virtual assistants and contextual computing, influencing how personal data could be integrated and surfaced seamlessly. Its acquisition by Apple reflects the strategic importance of AI-driven personal assistant technologies in competing with Google and others in the mobile ecosystem[4].
Quick Take & Future Outlook
Although Cue as a standalone product was discontinued post-acquisition, its core technology and vision have influenced Apple’s AI and personal assistant capabilities, such as Siri and Notification Center integration. Daniel Gross’s subsequent career, including leadership roles in AI at Apple and as a partner at Y Combinator, suggests ongoing influence in the AI and startup ecosystem[2][6]. The trends Cue tapped into—contextual AI, predictive search, and unified personal data management—remain central to the evolution of personal productivity tools and digital assistants, indicating that the foundational ideas behind Cue will continue to shape the tech landscape.

Origin Story
Cue was founded in 2010 by Daniel Gross and Robby Walker during their time at Y Combinator. Gross, an Israeli immigrant and AI enthusiast, and Walker, a prodigious technologist, initially launched Greplin as a personal search engine to unify users’ scattered online data. The idea emerged from Gross’s frustration that his smartphone did not intelligently organize his information or anticipate his needs. Early traction came from the app’s ability to search across multiple accounts and its freemium business model, which attracted both individual and business users. The company’s evolution into Cue marked a shift toward predictive, context-aware assistance, culminating in its acquisition by Apple in 2013[1][2][4].
