Overview
Sky (built by Signull Labs) is an iPhone app in private testing that replaces the traditional home-screen icon grid with an agentic, AI-driven widget layer. Instead of opening apps or chatbots, users get ambient intelligence via iOS widgets — drafting email replies, prepping for meetings, sending reminders, and flagging suspicious bank charges based on authorized data connections. Founder Nirav Savjani (ex-Google and Meta) raised north of $3.58M in pre-seed funding closing September 2025, with Andreessen Horowitz, True Ventures, SV Angel, and Offline Ventures participating per SEC filings and TechCrunch. The product remains pre-launch with tens of thousands on waitlists as of press coverage in 2025–2026.
Why Sky is interesting
Signull Labs raised a16z-backed pre-seed before public launch — ambient agents draft emails and flag charges from iOS widgets, not chat prompts.
Product & use cases
Sky uses iOS widgets as an agentic home screen — background agents continuously process email, calendar, location, and finance signals to surface actions and information without opening a chat UI.
- Proactive meeting prep and email draft suggestions on the lock screen
- Real-time alerts for suspicious spending or health metrics
- Location-aware recommendations without opening multiple apps

Competitive landscape
Edge: Widget-native agentic UX sidesteps App Store chatbot patterns and keeps AI one glance away — if Apple doesn't build it first.
Personal AI on mobile is crowded, but few products commit to widget-only ambient agents before launch. Sky's risk is inference cost for always-on agents and platform dependency on Apple's widget APIs.
-
Apple Intelligence / Siri incumbent
Platform owner with deep OS integration; Sky bets Apple moves slower on personalized agent feeds.
-
Rabbit R1 / AI hardware adjacent
Separate devices for AI actions; Sky stays on existing iPhones via widgets.
-
ChatGPT mobile app alternative
Reactive chat interface; not ambient widget-first.
Notable stories
- Sky attracted investor interest before shipping a public app — unusual for consumer mobile — on the thesis that the iPhone home screen hasn't changed materially in two decades (TechCrunch, 2025).
