Index Ventures partner Jahanvi Sardana advises early-stage founders to look beyond Total Addressable Market (TAM) when building startups.

She highlights that many successful companies, like Google and Microsoft, emerged from markets that were initially nonexistent.

Sardana categorizes TAM into known, emerging, and invisible markets, emphasizing the importance of understanding customer needs and demonstrating innovation, especially in creating new markets.

She advises founders to develop their own unique insights rather than relying solely on industry reports and metrics when evaluating their market.

Ultimately, investors prioritize evaluating founders' understanding of their customers and their ability to unlock supply and change behavior in the market.

The Indian government has blocked 25 streaming services, including popular platforms like Ullu and ALTT, due to concerns over "obscene" content. This action follows concerns raised by child protection and IT committees regarding mature content without adequate safeguards.

The Ministry of Information and Broadcasting issued directives to block access to these services' websites and apps, citing the Information Technology Act of 2000 and the IT Rules of 2021. Major platforms like Google Play and Apple App Store were contacted to restrict these services.

Some of the blocked services generated $5.7 million in revenue from in-app purchases, with 105 million downloads. While some services are no longer available on app stores, they persist through direct APK downloads.

Ullu reported a net profit of ₹212.3 million ($2.5 million) for FY2024, while ALTT generated ₹202.6 million ($2.3 million) in revenue in 2025. The crackdown is part of broader efforts to regulate streaming content in India, though enforcing these bans remains challenging.

According to Similarweb, AI platforms generated over 1.13 billion referrals to the top 1,000 websites globally in June 2025, marking a 357% increase year-over-year. However, Google Search still dominates, accounting for 191 billion referrals during the same period.

News and media sites saw a 770% increase in AI referrals since June 2024. Yahoo leads in AI referrals within the news media category with 2.3 million, followed by Yahoo Japan and Reuters.

ChatGPT accounts for over 80% of AI referrals to the top 1,000 domains. In e-commerce, Amazon leads with 4.5M referrals, followed by Etsy and eBay. Among tech and social sites, Google tops the list with 53.1 million referrals.

Meta CEO Mark Zuckerberg announced that Shengjia Zhao, formerly of OpenAI, will lead research at MetaSuperintelligence Labs (MSL). Zhao, a key contributor to ChatGPT and GPT-4, will set the research agenda under Alexandr Wang.

Meta has recruited top researchers from OpenAI, Google DeepMind, and Apple for MSL. Zuckerberg is investing heavily in AI, offering substantial compensation packages and building a 1-gigawatt cloud computing cluster, Prometheus, to support AI training.

Meta now has two chief AI scientists, Zhao at MSL and Yann LeCun at FAIR, focusing on long-term AI research. With these efforts, Meta aims to compete with OpenAI and Google in the AI space.

OpenAI CEO Sam Altman cautions ChatGPT users about the lack of legal confidentiality when using the AI for sensitive conversations, such as therapy. Unlike interactions with human therapists, lawyers, or doctors, conversations with ChatGPT are not protected by legal privilege. This poses a privacy risk, especially in legal contexts, as OpenAI could be legally required to disclose these conversations. Altman emphasizes the need for privacy standards similar to those in traditional therapy but acknowledges that this hasn't been addressed yet for AI interactions. OpenAI is contesting a court order in its lawsuit with The New York Times that would require saving chats from millions of ChatGPT users, excluding Enterprise customers.

Altman's warning is due to recent concerns about digital data as laws began limiting access to previously established freedoms.

Lyft will introduce autonomous shuttles manufactured by Benteler Group into its network by late 2026. These electric shuttles, operating under the Holon brand, will not include steering wheels or pedals and can accommodate up to nine seated and six standing passengers.

This move comes as Uber, Lyft's primary competitor, has been actively integrating robotaxis from various companies, including Waymo, WeRide, Baidu, Pony AI, Momenta, May Mobility, Volkswagen, Wayve, Nuro and Lucid Motors.

Lyft is also collaborating with May Mobility to deploy autonomous vehicles in Atlanta later this year and is working with Mobileye, whose technology powers the Holon shuttles.

Lucious McDaniel IV's food-delivery app, BiteSight, gained massive traction after a TikTok video showcasing the app went viral. The app, which allows users to watch videos of food before ordering and see recommendations from friends, resonated with young people.

The viral video led to a surge of new users, briefly placing BiteSight at No. 2 in the App Store's Food and Beverage category. McDaniel, a Y Combinator alum, believes BiteSight's focus on video and social recommendations, along with the use of AI to minimize overhead, differentiates it from competitors like DoorDash and Uber Eats.

BiteSight is currently available in New York, but McDaniel plans to expand nationwide. The company has also received significant interest from investors and restaurants.
