Investors Back Skye's AI iPhone Home Screen
Skye, an iPhone app from Signull Labs still in private testing, has raised more than $3.58 million in pre-seed funding and attracted a waitlist of “tens of thousands” of users ahead of a planned rollout. Built by a small team led by founder Nirav Savjani (who posts as signüll), Skye uses iOS widgets to create an "agentic homescreen" that surfaces ambient, personalized AI-driven insights — weather, context-aware recommendations, health signals — and can draft emails, prep for meetings, send reminders and flag suspicious bank charges via authorized connections. Early investors named in reporting include a16z (Andreesen Horowitz), True Ventures, SV Angel and Offline Ventures. PitchBook lists a post-money valuation of $19.5 million. The founder has said the app will launch to its waitlist soon but gave no firm timetable.
Early-stage consumer AI app and modest pre-seed funding; notable as a signal of consumer interest in ambient, agentic phone experiences but limited direct impact on AdTech/MarTech infrastructure.

Instinct AI Hits $2.5B Valuation in Weeks
Instinct, a personal AI assistant founded by Noah Shinn (author of the Reflexion paper), jumped in valuation from roughly $100M to $2.5B within weeks after successive funding rounds led by Kleiner Perkins, Benchmark and Index Ventures. The product remains an invite-only, free beta with no disclosed revenue or user numbers; investors are betting it could become a “personal AI gateway.” The article highlights the technical moat as hiding complex agent self-correction and orchestration behind a simple text/call interface, and raises concerns about the deep permissions such agents require (inbox, payment methods, calendars), recommending spending caps and confirmation gates as mitigations.
Instinct AI: The $10B Personal Agent Shaking Up Silicon Valley
Instinct, an invite-only personal AI agent for iMessage and WhatsApp, is generating significant buzz in the AI community, with reports of a valuation of $10B in funding talks.

The agent integrates with Google Workspace, can make calls, book appointments, order food, and interact with other Instinct agents via a 'Trusted People' network, positioning itself as a multi-purpose personal assistant. While praised for its ease of use and powerful features, concerns remain about data security and potential misuse of payment information, leading the reviewer to adopt a cautious approach by limiting access to a spend-limited card.
