Skye, an iPhone app still in private testing, wants to change how people interact with AI on their smartphones. And even before it’s launched, it’s already attracted interest online and from investors and “tens of thousands” of users, according to its creator — a sign that consumers might want a more AI-aware iPhone.
Instead of launching an app or speaking to an AI chatbot, the startup is working to design an “agentic homescreen” for the iPhone, using iOS widgets as its interface.
Through those widgets, Skye would bring a sort of ambient intelligence to your device, offering personalized insights about your local weather, your current context, your health, and more, according to a post from its creator, who goes by signüll on X. The app can also draft email replies, help you with your meeting prep, send reminders, and flag suspicious charges in your bank accounts. Its creator also claims it can provide location-specific recommendations and additional information about local businesses, neighborhoods, and attractions while you’re out and about.
Much of this data would be pulled in through authorized connections granted by the user.
The app, which is being built by a small team from the startup Signull Labs, has already attracted investor attention, despite not yet having a public product.
According to an SEC filing, the startup has raised north of $3.58 million in pre-seed funding, in a round that closed in September 2025. PitchBook also currently lists New York-based Signull Labs’ funding along with a post-money valuation of $19.5 million.
Since announcing the startup’s plans on X, signüll, whose name TechCrunch confirmed as Nirav Savjani according to the SEC filings and other documents, claims the app has added “tens of thousands” of users to the waitlist. This metric, if accurate, would suggest strong consumer interest in a more AI-aware iPhone. (And the possibility that a new type of AI device, like the rumored OpenAI smartphone, could have a chance.)
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… https://t.co/jqtU9zELqH

TechCrunch spoke to signüll, who shared more about the product and funding, under the condition of protecting his pseudonymity. TechCrunch declined, as signüll’s name is listed publicly in the SEC filings establishing Signull Labs. (TechCrunch said we would still be happy to publish an interview with him when he’s prepared to go on the record.)
The founder noted he’s previously worked at Google and Meta, though he has no obvious LinkedIn presence. He also told TechCrunch that Skye’s early backers included a16z (Andreessen Horowitz), True Ventures, SV Angel, and other individuals. Offline Ventures also lists Signull Labs in its online portfolio, we found.
Since announcing Skye, Savjani has appeared on the TBPN podcast as his avatar and has been posting on X about his use of the app.
He told TechCrunch that the Skye app plans to launch to its waitlist of users soon, though he declined to give specifics.
