Skye bets an AI home screen replaces iPhone apps; $3.58M before launch
Pre-launch iPhone app Skye puts ambient AI on the home screen via widgets, pulling tens of thousands onto its waitlist and a $3.58M pre-seed.
Signull Labs (Skye)
What the business is
An iPhone app, still in private testing, that turns the iOS home screen into an agentic surface: widgets deliver ambient intelligence (weather, context, health), draft email replies, prep for meetings, send reminders and flag suspicious bank charges.
Starting capital：$3,579,999 sold out of a $3,999,999 Regulation D offering, first sale 2025-09-08, per SEC Form D; backers include a16z, True Ventures and SV Angel (per TechCrunch).
How it started
Signull Labs was incorporated in Delaware in 2025; founder Nirav Savjani, a former Google and Meta employee, announced Skye on X under the pseudonym signüll. The pre-seed round closed in September 2025, and the SEC filing lists Savjani as CEO of the New York company.
What happened
After the X announcement, the app added 'tens of thousands' of users to its waitlist despite having no public product, per TechCrunch (April 2026). Savjani has appeared on the TBPN podcast as an avatar and continued posting about the app; investors backing the round include a16z, True Ventures and SV Angel, with Offline Ventures listing Signull Labs in its portfolio.
No ending yet — it is still running.
Background
Skye is an iPhone app from New York-based Signull Labs that bets the next AI interface is the home screen itself. Rather than launching an app or talking to a chatbot, users get an 'agentic homescreen' built from iOS widgets: ambient intelligence about local weather, current context and health, plus actions like drafting email replies, meeting prep, reminders and flagging suspicious bank charges, with data pulled through user-authorized connections.
The bet is contrarian because it precedes the product. Signull Labs was incorporated in Delaware in 2025; founder Nirav Savjani, an ex-Google and ex-Meta engineer who posts on X as signüll, closed a pre-seed round in September 2025 (a $3,579,999 Form D) and only then built a waitlist - which TechCrunch reported had grown to 'tens of thousands' of users by April 2026, while the app was still in private testing.
Investors were convinced before launch: TechCrunch reported early backers included a16z, True Ventures and SV Angel, and PitchBook lists a $19.5 million post-money valuation. Savjani has kept his pseudonym in public and declined a full on-record interview, which made the company's claims harder for reporters to verify.
The open question is whether users will trust a widget layer with the permissions and context needed to act on their behalf, and whether Apple's own home-screen AI features will make a third-party layer redundant before Skye launches to its waitlist.
What has to be true
- Skye targets the surface with the most daily attention - the home screen - instead of competing for installs of another app or chatbot.
- The pre-seed closed (September 2025) before any public product, so the round itself was a bet on the thesis rather than on traction.
- Waitlist growth to 'tens of thousands' without a launch is concrete evidence of consumer interest in an AI-aware phone, per TechCrunch.
- Backing from a16z, True Ventures and SV Angel at a $19.5M post-money valuation gave the pre-launch company credibility with later customers and press.
- The pseudonymous founder created a verification problem: reporters could confirm the company through SEC filings but not the product's claims, raising the bar for trust.
What can be applied
Bet on the surface users already stare at: put ambient AI on the home screen instead of asking for another app - and use waitlist demand, not a shipped product, to prove interest.
Aftermath
As of April 2026 Skye remains in private testing with no launch date announced. The waitlist has 'tens of thousands' of users per TechCrunch, and the founder has said the app plans to launch to that waitlist soon. The company is a small team out of New York, listed with $3,579,999 sold under a $3,999,999 offering in its September 2025 SEC Form D. The key risk is competitive: Apple's own AI features on the home screen could render a third-party widget layer obsolete before Skye ships.
