Lyft connects riders with drivers via a mobile app in urban areas in the US and Canada, offering rides, bike and scooter rentals, and ads. Riders request a trip and a nearby driver accepts; Lyft takes a commission from the fare and also earns from rentals, subscriptions like Lyft Pink, and advertising. Lyft differentiates itself by combining multiple mobility options in one app, using a flexible gig-economy driver model, and prioritizing safety and ease of use. Its goal is to provide convenient urban transportation with diverse services while maintaining steady revenue and a positive user experience.

Project Move-In helps NYCHA students prepare for college.

Project Move-In helps NYCHA students prepare for college. Moving from home to a college dorm or off-campus housing is often the first experience young people have living on their own. Project Move-In, a program from NYC Service, helps make that transition a little easier for college-bound NYCHA residents by providing them with essential items to start their college journey. The New York Yankees, a Project Move-In sponsor for the third year in a row, hosted a distribution event on July 27 at Yankee Stadium, where 100 NYCHA residents received college essentials and free tickets to a future Yankees game. Each student got a duffel bag filled with school necessities, including a laptop, wireless earbuds, portable Bluetooth speaker, charger, flash drive, extension cord, shower caddy, twin XL sheet set with comforter, pillow, towel, pop-up hamper, reusable water bottle, and other items. Participants were selected through an application process. The Public Housing Community Fund supported the initiative again this year through its partnership with Lyft and provided students with $40 vouchers towards their rides home to transport their new belongings. Isaacs Houses resident Aliya Toure was among this year's participants. She will be attending Haverford College in Pennsylvania and plans to major in political science and minor in education. "It was relieving to be one of the recipients and to know that I had a few things I could knock off my list of dorm essentials," Ms. Toure said. "It was a very nice experience, and I was happy to be chosen. My favorite items were the portable charger and the command hooks because those are things I didn't think about needing but I'm grateful to have." Mott Haven Houses resident Tionne Bartlett is also grateful to be a Project Move-In recipient. She will begin her freshman year at SUNY Oneonta, where she plans to major in film and media studies. "This took a financial burden off of me," Ms. Bartlett said. "I know many of the items cost a lot and because I'm not making a lot of money this summer, at least I can save more money and worry about the next things on my list. I'm grateful that my mother found this resource and signed up for me." Ms. Bartlett was especially excited to receive a brand-new laptop. As she prepares to leave home, she is looking forward to experiencing a new part of New York State and meeting new people. "I'm excited to explore, get some fresh air, make new friends and more connections, and to get the college experience that my parents never had," she said. "We are so proud of our NYCHA residents who are taking this next step in their educational journeys," NYCHA Chief Executive Officer Lisa Bova-Hiatt said. "Starting college is an exciting milestone, but it can also come with new challenges and expenses. We are grateful to NYC Service, the New York Yankees, the Public Housing Community Fund, and Lyft for providing young people with resources for a strong start so they can focus on learning, new experiences, and the opportunities ahead."

Travis Kalanick has 'no regrets' over failed Lyft acquisition due to cultural differences

Travis Kalanick, Uber's co-founder and former CEO, said he has no regrets about the company's failed attempt to acquire Lyft in 2014. In an interview released Friday by Andreessen Horowitz, Kalanick stated the two companies were "very culturally different." Uber had held acquisition talks with Lyft, but negotiations collapsed over disagreements on valuation and other terms. "I would sit across the table from the guys and it was just clear that we were very culturally different," Kalanick said. Kalanick resigned as CEO in 2017 after major investors demanded his departure following months of controversy, including allegations of gender discrimination and sexual harassment at the company. He left Uber's board in late 2019.

Asvar Law secures over $66,000 in sanctions against Lyft for willful case delays.

Asvar Law secures over $66,000 in sanctions against Lyft for willful case delays. Judge Rules Lyft Withheld Evidence and Delayed Discovery in a Pre-Proposition 22 Dispute Over Gig-Worker Classification LOS ANGELES, Aug. 18, 2026 /PRNewswire/ - Asvar Law, P.C. announced today that a California Workers' Compensation Appeals Board judge has sanctioned Lyft, Inc. a total of $66,735 for willfully delaying discovery and repeatedly violating court orders to produce employment records in a catastrophic-injury case, finding that Lyft "acted with malice." The underlying case involves Mark Nahvi, a former Lyft driver who suffered catastrophic, permanent injuries after being violently attacked by a passenger while driving for Lyft in March 2018. Nahvi has sought workers' compensation benefits ever since, but Lyft has denied his claim, contending he was an independent contractor rather than an employee - a classification issue that remains central to the case. Since 2021, Nahvi's attorneys have sought Lyft's business and employment records through a subpoena and a series of subsequent court orders issued by four different Workers' Compensation Appeals Board judges. According to Findings, Award and Orders issued on July 20, 2026 by Workers' Compensation Administrative Law Judge M. Victor Bushin, Lyft repeatedly failed to comply with orders compelling production - including a February 2024 order compelling production of documents, and a March 2025 finding by a court-appointed discovery referee that Lyft's delay was "unreasonable". In his opinion, Judge Bushin wrote that Lyft "willfully delayed" the case and that "the undersigned WCJ further finds Lyft acted with malice." The judge awarded $64,735 in attorney's fees and imposed an additional $2,000 sanction. The dispute unfolds against the backdrop of California's long-running fight over gig-worker classification - from the state Supreme Court's 1989 Borello decision, through the 2018 Dynamex ruling and the 2019 passage of Assembly Bill 5, to the 2020 passage of Proposition 22, a ballot measure heavily funded by Lyft, Uber, and other gig-economy companies that exempted app-based drivers from AB 5. Nahvi's 2018 injury predates Proposition 22 by more than two years. About Asvar Law, P.C.: Asvar Law is a premier personal injury and workers' compensation law firm serving all of California, specializing in catastrophic injury and traumatic brain injury litigation. Asvar Law has twice set the national record for the highest workers' compensation settlement in the nation. SOURCE Asvar Law, PC

Indian-Origin entrepreneur recalls H-1B setback, deportation scare before becoming U.S. Citizen.

Indian-Origin entrepreneur recalls H-1B setback, deportation scare before becoming U.S. Citizen. Share the news iNDICA NEWS BUREAU- For Indian-origin entrepreneur Saiman Shetty, becoming a U.S. citizen marked the end of a long and difficult immigration journey that began with a one-way ticket from a village in Karnataka and took him through student debt, an H-1B lottery setback, immigration backlogs and a near deportation scare. He shared the story on Instagram after becoming a U.S. citizen, saying his experience had made him more determined to support other immigrants navigating the country's immigration system. "Today, I am an American. But this story doesn't start here. It starts in a village in Karnataka you won't find on any map. A broke international student, a one-way ticket, and the flaming hot desert of Arizona waiting on the other side. New country, new language, new everything. The first person in my family to ever set foot on this side of the world. No friends. No safety net. No plan B," Shetty said. He said his path to citizenship was far from easy and that the U.S. had repeatedly tested him. "America did not roll out a red carpet. She beat me up. She tested me at every single turn. The debt I didn't know how I'd repay. The jobs that said no. The H1B lottery I lost. The backlogs. Walking away from a comfortable Silicon Valley paycheck to go build something of my own. Every step, I had to prove myself. Again. And again," he detailed. According to his LinkedIn profile, Shetty previously worked at Tesla and Lyft before starting his own venture, Smart Immigrant AI, where he is the Founder and CEO. His immigration journey also took an unexpected turn when he said people accused him of being a "fraud" and reported the allegations to U.S. Citizenship and Immigration Services (USCIS). "A few jealous pricks decided I was a 'fraud' and built a neat little trap for me. Handed it to USCIS with a bow on top. And for a moment, the most powerful immigration system on earth almost took the bait," Shetty said. He, however, did not provide further details about the allegations in his post, but said the matter ultimately ended in his favor. "But there's one thing this country is known for above all else. And in the end, that's exactly what showed up. Justice," he said. Shetty said the experience had strengthened his commitment to helping immigrants, including those dealing with the uncertainty of the F-1 student visa, H-1B and O-1 visas, L-1 visas and green card backlogs. "So here's why I'm really posting this. If you're on an F1, scared and half a world from home. This is for you. If you're on an H1B, an O1, an L1, watching the clock and praying to the lottery gods. This is for you. If you're stuck in a green card backlog that feels like it will never end. This is for you. And if you're anyone, anywhere, daring to dream a life bigger than the one you were handed. This is for you," he added. Shetty said he now wants to use his experience to support immigrants who are still going through the process. He said more than 300 immigrants whom his organization has helped are expected to go through a similar journey in the coming years. "Trolls wanted me deported. Instead, I'm an American. And I am still, very much, an immigrant. Fighting harder for us than I ever have. 300+ immigrants that we've helped will soon walk this same path in a few years," he said. Shetty ended his message by urging immigrants not to give up on their goals while following the law. "Don't you dare give up. Follow the law, do the right thing and keep working hard! This is only the beginning," he concluded. Photo: Instagram
