Jack Dorsey Launches Sun Day App for UV Exposure and Vitamin D Tracking

Jack Dorsey, co-founder of Twitter, has released a new app called Sun Day, designed to help users track their UV exposure and vitamin D intake. The app is currently available on iOS via TestFlight and its code is open-source on GitHub.

Sun Day provides information on the UV Index for the user's location, including details on cloud cover, sunrise, and sunset. Users can input their skin type and clothing to calculate safe sun exposure times.

The app also tracks vitamin D intake during sun exposure sessions. By starting and ending a session, users can see how much vitamin D they've gained. Dorsey developed the app using an open-source coding tool called Goose.

SpaceX Considers $2 Billion Investment in Elon Musk's AI Startup xAI

According to a Wall Street Journal report, SpaceX is considering a significant investment of $2 billion in Elon Musk's AI startup, xAI. This investment would be part of a larger $5 billion equity raise announced by Morgan Stanley in late June.

This would mark SpaceX's first major investment in xAI. The two companies already have existing collaborations, as xAI's Grok chatbot is used to power customer service for SpaceX's Starlink internet service. There are plans for further partnerships between the companies.

Musk has a history of integrating his various companies, such as merging xAI with X (formerly Twitter) earlier this year. Despite some controversies surrounding Grok, Tesla is also planning to bring the chatbot to its vehicles.

UK Government Backs Underrepresented Founders with £500M Investment

The British Business Bank (BBB), a UK government entity, is launching a £500 million package to support diverse and underrepresented fund managers and founders. £50 million is earmarked for female-led venture funds, bringing the BBB's total commitment to this area to at least £100 million. A further £400 million will support diverse fund managers, early-stage companies, and talent development for individuals from disadvantaged backgrounds. The initiative, set to begin in 2026, aims to address the significant venture capital investment gap for underrepresented groups, with a target of at least 50% of investment going to female fund managers. This move is part of the UK's broader effort to attract and retain talent within its venture ecosystem and drive economic growth by breaking down barriers to opportunity.

Sequoia's Gamble: Navigating Controversy with Silence

Sequoia Capital is facing a crisis due to partner Shaun Maguire's inflammatory social media posts. Maguire's comments about a New York City mayoral candidate have sparked outrage and a petition demanding Sequoia condemn the remarks.

Sequoia's strategy of silence is being tested, as the firm's response (or lack thereof) has drawn criticism. Maguire's controversial stance may be strengthening his position. Sequoia's calculated gamble carries risk, including the possibility of further backlash or alienation of potential business partners.

Sequoia's historical approach has been to give partners space to express themselves publicly, but there's a distinction between political diversity and incendiary rhetoric. The firm has precedent for taking action when a partner's behavior crosses a line, as seen with Michael Goguen.

Sequoia's silence carries risks, including alienating diverse talent and being seen as tacitly endorsing Maguire's views. The firm's reputation is at stake in an increasingly connected global market.

Ultimately, whether Sequoia's bet pays off will depend on how long the controversy lingers, how much business it costs Sequoia, and whether Maguire can resist the urge to push things past Sequoia's own tolerance threshold.

Google DeepMind Hires Windsurf's Leadership After OpenAI Acquisition Fails

OpenAI's $3 billion deal to acquire Windsurf fell apart, leading Google DeepMind to hire Windsurf's CEO Varun Mohan, co-founder Douglas Chen, and top researchers. Google confirmed the hiring, aiming to advance their work in agentic coding. This deal is a reverse-acquihire, where Google licenses Windsurf's technology without acquiring the company, similar to past deals with Character.AI and Microsoft.

Windsurf's head of business, Jeff Wang, will become interim CEO. Most of Windsurf's 250-person team will continue offering AI coding tools for enterprise customers. OpenAI's failed acquisition caused tension with Microsoft. Windsurf's ARR reached $100 million in April, attracting interest from OpenAI and Google.

The addition of Windsurf's leaders could boost Google's AI coding tools, aligning with the industry trend of offering AI coding applications. Windsurf's future is uncertain, as other AI startups have struggled after similar deals.

Ethical Dilemma: Paragon's Spyware Contract with ICE Under Scrutiny

Paragon, an Israeli spyware company claiming ethical practices, faces scrutiny over a $2 million contract with U.S. Immigration and Customs Enforcement (ICE). The contract, signed in September 2024, is under review due to concerns about compliance with a Biden-era executive order restricting the use of spyware that could be used to violate human rights.

The contract remains on pause, with Homeland Security reviewing its compliance with the executive order. The Trump administration's position on the order remains unclear. Paragon previously cut ties with Italy after its spyware was misused, but now faces the ethical question of supplying its tools to ICE.

Critics, like Access Now, urge Paragon to reconsider the agreement given ICE's record on human rights. The decision could test Paragon's claim of being an 'ethical' spyware vendor, as it navigates the ethical implications of its government contracts.
