Skye, an iPhone application currently under private testing, aims to transform the way individuals engage with AI on their smartphones. Even prior to its official release, it has garnered attention online from both investors and “tens of thousands” of users, as stated by its creator — a sign that there may be a demand for a more AI-enabled iPhone among consumers.

Instead of rolling out a standard app or interacting with an AI chatbot, the startup is focused on developing an “agentic homescreen” for iPhones, utilizing iOS widgets as its means of interaction.

With these widgets, Skye aims to introduce a type of ambient intelligence to your device, providing customized insights regarding your local weather, current situations, health, and more, as mentioned in a post by its creator, known as signüll on X. The app is also capable of composing email responses, assisting you with meeting preparations, sending reminders, and notifying you of questionable transactions in your bank accounts. Its creator further asserts that it can offer location-specific suggestions and extra details about nearby businesses, neighborhoods, and attractions while you’re out.

Most of this information would be retrieved through user-granted authorized connections.

This application, being developed by a small team at Signull Labs, has already garnered investment interest, despite lacking a publicly available product.

An SEC filing indicates that the startup has raised over $3.58 million in pre-seed funding, in a round that concluded in September 2025. PitchBook also currently records New York-based Signull Labs’ funding along with a post-money valuation of $19.5 million.

Following the announcement of the startup’s objectives on X, signüll, whose real identity TechCrunch has confirmed to be Nirav Savjani according to SEC filings and other documents, claims that the app has garnered “tens of thousands” of users on the waitlist. If this claim holds true, it would indicate significant consumer interest in a more AI-integrated iPhone. (Additionally, there may be potential for a new kind of AI device, such as the speculated OpenAI smartphone, to have viable prospects.)

TechCrunch engaged with signüll, who provided further insights regarding the product and funding, while requesting to maintain his pseudonymity. TechCrunch declined, as signüll’s name is publicly listed in SEC documents related to Signull Labs. (TechCrunch stated they would still welcome an interview with him once he feels ready to go public.)

The founder mentioned his prior experiences at Google and Meta, although he lacks a recognizable LinkedIn profile. He also informed TechCrunch that Skye’s initial investors include a16z (Andreessen Horowitz), True Ventures, SV Angel, among others. Additionally, Offline Ventures lists Signull Labs in their online portfolio, as we discovered.

Since the announcement of Skye, Savjani has engaged in discussions on the TBPN podcast using his avatar and has been sharing updates on his experience with the app on X.

He informed TechCrunch that the Skye app is set to launch to its waitlisted users shortly, though he refrained from providing detailed timelines.
