Skye, an iPhone app still in private testing, wants to fundamentally change how people interact with artificial intelligence on their smartphones. Rather than requiring users to open a separate app or speak to a chatbot, the startup is designing an “agentic homescreen” for the iPhone using iOS widgets as the primary interface. Even before its public launch, the app has drawn significant interest from investors and accumulated tens of thousands of waitlist signups, according to its creator.
The app is being built by a small team at Signull Labs, a New York-based startup that has raised at least $3.58 million in pre-seed funding, according to an SEC filing dated September 2025. Pitchbook lists a post-money valuation of $19.5 million. Early backers reportedly include a16z (Andreessen Horowitz), True Ventures, SV Angel, and Offline Ventures, which lists Signull Labs in its online portfolio.

How Skye Works
Skye aims to bring ambient intelligence to the iPhone through a set of iOS widgets that provide personalized insights without requiring direct user input. According to a post from the startup’s creator, who goes by the handle signüll on X (and whose legal name, Nirav Savjani, appears in SEC filings), the app can offer context-aware information about local weather, health data, current location, and more.
The app can also draft email replies, assist with meeting preparation, send reminders, and flag suspicious charges in bank accounts. When users are out, Skye can provide location-specific recommendations and information about local businesses, neighborhoods, and attractions. Much of this data is pulled in through authorized connections granted by the user.

Strong Early Demand
Since publicly announcing the startup’s plans on X, signüll claims the app has added “tens of thousands” of users to its waitlist, which already stood at 25,000 prior to the announcement. In a post from April 14, 2026, signüll wrote: “holy fuck the response to yesterday’s lunch has been absolutely unreal. ~million views on our video, tens of thousands added to a waitlist that was already 25k+, & hundreds & hundreds of emails & DMs from investors & ppl genuinely excited about what we’re building.”
If accurate, this level of demand suggests strong consumer appetite for a more AI-aware iPhone experience. It also raises the possibility that a new category of AI device, such as the rumored OpenAI smartphone, could find a receptive market.
Founder Background and Transparency
The founder, who uses the pseudonym signüll, told TechCrunch he previously worked at Google and Meta, though he maintains no obvious LinkedIn presence. TechCrunch declined to grant him full pseudonymity during interviews, as his legal name is publicly listed in SEC filings. The founder has since appeared on the TBPN podcast using an avatar and has been posting about his personal use of the app on X.
Savjani told TechCrunch that Skye plans to launch to its waitlist soon, though he declined to provide a specific timeline.
Conclusion
Skye represents a notable attempt to reimagine the smartphone homescreen as an intelligent, proactive interface rather than a static grid of apps. With significant pre-seed funding from top-tier investors and a growing waitlist, the startup is positioning itself at the intersection of consumer AI and mobile operating system design. Whether Skye can deliver on its ambitious vision will become clearer once the app reaches users in the coming months.
