Skye, an innovative iPhone application currently undergoing private testing, aims to revolutionize the way users engage with artificial intelligence on their mobile devices. Even prior to its official launch, the app has garnered significant attention online, drawing interest from investors and attracting "tens of thousands" of users to its waitlist, as reported by its creator. This early traction suggests a substantial consumer appetite for a more deeply integrated and AI-aware iPhone experience.
Diverging from the conventional approach of launching a standalone app or a dedicated AI chatbot, the startup is developing an "agentic homescreen" for the iPhone, leveraging iOS widgets as its primary interface.
Through these intelligently designed widgets, Skye proposes to imbue your device with a form of ambient intelligence, delivering personalized insights pertaining to local weather conditions, your current context, health metrics, and more. This information is based on claims from its creator, who operates under the handle "signüll" on X. The application is also designed to assist with drafting email responses, streamlining meeting preparations, dispatching reminders, and identifying potentially suspicious transactions within your bank accounts. Furthermore, its creator asserts that Skye can furnish location-specific recommendations and supplementary details about local businesses, neighborhoods, and attractions as you navigate your surroundings.
Critically, the majority of the data utilized by Skye would be accessed via authorized connections, explicitly granted by the user, ensuring privacy and control.
Developed by a compact team at the startup Signull Labs, the application has already captured the attention of investors, despite not yet having a publicly available product.
According to an SEC filing, the startup successfully secured over $3.58 million in pre-seed funding, with the round concluding in September 2025. Pitchbook further corroborates this by listing New York-based Signull Labs' funding alongside a post-money valuation of $19.5 million.
Since publicly announcing the startup's ambitious plans on X, signüll – whose identity TechCrunch confirmed as Nirav Savjani through SEC filings and other documentation – claims the app's waitlist has expanded by "tens of thousands" of users. This metric, if accurate, strongly indicates robust consumer interest in a more AI-centric iPhone. It also potentially hints at the viability of new categories of AI-focused devices, such as the rumored OpenAI smartphone.
In a public post, signüll expressed the overwhelming reception, stating: "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. our discord is…"
TechCrunch engaged in discussions with signüll, who provided additional details regarding the product and its funding, initially requesting to maintain his pseudonymity. However, TechCrunch declined this condition, citing that signüll’s name is publicly listed in the SEC filings establishing Signull Labs. TechCrunch noted its willingness to publish an interview with him once he is prepared to go on the record.
The founder disclosed his prior professional experience at prominent tech companies like Google and Meta, although he does not maintain an easily discoverable LinkedIn presence. He also informed TechCrunch that Skye's early financial supporters include notable firms such as a16z (Andreesen Horowitz), True Ventures, SV Angel, and various individual investors. Our research also revealed that Offline Ventures lists Signull Labs within its online portfolio.
Following the announcement of Skye, Savjani has made appearances, including on the TBPN podcast as his avatar, and has actively posted on X, sharing his experiences and insights regarding the app's usage.
He conveyed to TechCrunch that the Skye app is slated for an imminent launch to its waitlisted users, though he refrained from providing specific dates or details.
