WhatsApp has started rolling out username reservations for its users in India, marking a shift from phone number-based identification to platform-managed usernames. This change aims to enhance user privacy by reducing the need to share contact numbers, which can expose individuals to SIM-swap attacks and phishing attempts. However, security experts and Indian regulators are raising concerns about potential impersonation risks and online fraud. The Ministry of Electronics and Information Technology (MeitY) has warned WhatsApp not to roll out the feature until consultations are completed due to fears it could facilitate digital scams and impersonations.
Apple's Hide My Email feature is supposed to protect user privacy by providing disposable email addresses. However, a severe bug allows these addresses to reveal the user’s true email address, compromising online anonymity. This flaw affects anyone using Apple devices and services that rely on this feature for privacy protection. The vulnerability was reported by 404 Media over a year ago but remains unaddressed. All attempts to exploit it have been successful in limited tests with volunteers. Let's dive deeper…

Summary: WhatsApp is rolling out username reservations in India, aiming for better privacy but facing scrutiny over potential impersonation risks. MeitY warns against rollout until concerns are addressed.
Key Points:
More than 500 million users on WhatsApp in India will be affected by the new feature.
Meta reserves usernames for public figures and government entities to prevent impersonations, but criteria remain unclear.
The Ministry of Electronics and Information Technology (MeitY) sent a notice to WhatsApp warning against potential fraud risks.
Critics argue that lookalike usernames could increase online scams and phishing attacks in India's largest market.
WhatsApp allows users to claim existing Instagram or Facebook usernames by linking their accounts.
Why it matters: The rollout of username reservations on WhatsApp impacts over 500 million Indian users, potentially reducing SIM-swap risks but introducing new impersonation threats. Regulators and security experts are concerned about the feature's implications for online safety, especially in India where digital scams are prevalent.

Summary: Apple's Hide My Email has a critical bug exposing real email addresses, compromising user privacy. Reported over a year ago and still not fixed.
Key Points:
A researcher from 404 Media reported the vulnerability to Apple more than a year ago.
In tests with volunteers, 100% of Hide My Email addresses were successfully exploited.
Publicly accessible people-search sites make it easy to link an email address to personal details.
Apple has faced similar privacy issues before, including lawsuits over iPhone analytics data.
The bug remains unaddressed by Apple despite the risk of widespread exploitation.

Summary: Together AI just raised a whopping $800M at an $8.3B valuation, backing open-source model adoption. Why you should care: More support for neoclouds means better tools and lower costs for developers using these models.
Key Points:
Together AI's Series C round was led by Aramco Ventures with Nvidia among others, totaling $800 million at an $8.3 billion valuation.
The company raised a $102.5 million Series A in 2023 and a $305 million Series B about 16 months ago.
Together AI's annual bookings are over $1.15B, tripling open source model usage across the industry in just one year.
The company has thousands of paying customers including Cursor, Cognition, and Decagon, with backing from Kleiner Perkins and Nvidia.
Neoclouds like Together AI have been hot commodities for VC investment, with Upscale AI raising $500M last month.

Summary: Lime went public on Nasdaq, raising $167M — crucial for addressing debt and expanding its tech-driven micromobility operations.
Key Points:
Lime raised $167 million in IPO, selling 6.68 million shares at $25 each
Company's valuation pegged at around $1.6 billion on Nasdaq under ticker 'LIME'
Revenue grew from $521M in 2023 to $886.7M last year; losses narrowed from $122.3M to $59.3M
Operating in 230 cities across 29 countries, Lime aims for more city partnerships post-IPO
Uber owns 24% of Lime and accounted for over 14% of its revenue last year
Why it matters: If you're a city planner considering micromobility options, Lime's IPO signals financial stability. The company's focus on unit cost reduction and tech-driven operations could set new standards in the industry. However, with significant debt, Lime needs public market access to sustain growth.
New Tools & Job
Sakana Marlin - Sakana Marlin is Sakana AI's first commercial product: an autonomous 'Ultra Deep Research' agent positioned as a Virtual Chief Strategy Officer. Given a research topic, Marlin works autonomously for up to roughly eight hours, forming hypotheses, gathering and reconciling information from online sources, and synthesizing a detailed strategy report up to ~100 pages plus executive-summary slides. It builds on Sakana AI research including AB-MCTS (NeurIPS 2025 Spotlight) and The AI Scientist (published in Nature). A closed beta ran from April 2026 with ~300 professionals across finance and consulting.
Upsolve AI - Upsolve AI is an Agent Studio for data teams to build, deploy, and evaluate grounded, governed, and trustworthy analytics agents. It layers institutional context (warehouse tables, validated SQL patterns, semantic models, KPI definitions, and business rules from sources like Notion, Slack, and email) on top of 30+ SQL database connectors so end users can ask questions in natural language and get accurate, traceable answers. Every conversation is fully traced end-to-end (tool calls, SQL, agent output), a built-in evaluation agent grades performance, and context monitoring surfaces gaps so accuracy improves with use. Agents deploy to Slack, Teams, Claude, ChatGPT, Cursor, or embed in your own product via MCP/SDK.
Buddy - Buddy is an AI design agent that lives in the Figma canvas. Chat to generate screens, flows, components, and variants using your existing design system; paste a public URL or drop an HTML file to recreate live websites as editable Figma layers; and run batch edits and layer organization across files. Supports multiple LLMs (Opus, Sonnet, GPT, Gemini, Codex). Works on any Figma plan including Free.
Tyto - Tyto by ai-coustics is a monitoring and diagnostics layer for Voice AI. It produces a single real-time risk score that predicts speech-to-text, voice-activity-detection, and turn-taking failures before they occur, scoring six qualities of incoming audio so teams can catch audio issues before they impact voice agents in production.
Adapt - Adapt is one shared context layer for every employee and every agent. It connects to the tools a company runs on, holds live context, answers questions, and takes action that does the work and cites its sources, in Slack and on the web. Data stays private and is never used to train models.
