99dresses

We're creating every women's fantasy by combining the unwanted…

99dresses allows women all across the U.S. to buy, sell & trade fashion with thousands of shopaholics. Nikki Durkin, the founder of 99dresses, was sick of spending so much money on new clothes only to get bored with them a week later and rarely ever wear them again. She started 99dresses in her home country of Australia as a way for thousands of Aussie girls to conveniently trade fashion with each other online. Now based in NYC and working with a fantastic team (Marcin, Chandra, Oguz & Clare), she is bringing 99dresses to women across the USA. Get the iOS app: http://bit.ly/1fWeoRG

Aidy logo

Aidy

Mobile app helping people better manage chronic health conditions

Aidy is a mobile app that helps people live fuller lives with chronic health conditions, beginning with Inflammatory Bowel Disease (Crohn’s Disease and Ulcerative Colitis). Our app lets users easily log their symptoms, diet, and treatments, then uses clinical indices to track disease severity and trends over time. Aidy excels at identifying patterns between diet, treatment adherence, and symptoms, giving our users a much more comprehensive and up-to-date picture of their condition to supplement clinician care. Previously in our careers, both Max and Peter worked in health in different capacities. At the Rockefeller Foundation and the United States Senate, Max worked in public health policy and COVID-19 response, while Peter worked as an ML researcher for a number of biotech companies. After a lengthy “pivot hell” we decided to finally listen to a friend with IBD who insisted that there weren’t any decent apps to help people live with the disease. Pretty quickly, we discovered how LLMs and regular structured questionnaire responses could provide a level of patient empowerment not possible before for chronic diseases. From there, Aidy was (re)born!

AirCaps

AR glasses to better understand, remember and learn from conversations

We're building lightweight AR glasses that help you understand, remember and learn from conversations. AirCaps displays captions, translations, summaries and proactive insights for your conversations in your field of view in real-time. We're starting with real-time captions for hearing loss. We did $90K in sales in October (grew 6.5X from September), have users averaging 6h+ daily use, and went viral on TikTok (75M views). Madhav (Yale CS, MIT Media Lab audio AI) and Nirbhay (Cornell CS) have been obsessed with smart glasses for 11 years—building Google Glass apps from age 13. People spend 3 hours a day in meaningful conversations—negotiations, interviews, pitches, conflicts, first dates. They struggle to comprehend 25-50% of them, forget 70% within 24 hours and 90% within a week, and have no way to learn and improve from their conversations. AR glasses are the only form factor that can augment conversations without disrupting them. They keep your hands free, allow you to maintain eye contact, provide information exactly when needed, and have unfiltered access to everything you hear and see. In 5 years, 4.7 billion smartphone users will use smart glasses. But today's AR glasses are too heavy, conspicuous, and power hungry while failing to provide utility: generic toys without purpose. Conversations demand real-time, hands-free, eyes-up assistance precisely when you can't look away—the killer use case to kickstart mass adoption. If we're right, we'll own the gateway to the next interface for technology.

Aisle50

Grocery deals.

Aisle50 came out of the summer 2011 class at Y Combinator, the Silicon Valley accelerator. Aisle50 builds CPG and retailer campaigns aimed to get both banner and brand incremental shoppers, bigger share and valuable brand messaging to consumers. Our product has a two-year track record of producing baskets that are 30% larger for our retailers. We also give our retailer partners incremental trips that, in the past, they would have lost to competitors. Aisle50 content, because much of it is in the form of offers that are paid for through Web or Mobile, compel the consumer to head to the store sooner rather than later. Everybody wins: We drive trips to stores, new customers to CPGs and big discounts to consumers.

Allo logo

Allo

Allo is an app that helps neighboring families meet and help each…

Allo connects neighboring families to help them establish their local "village" for social and practical support. At Allo, we believe children benefit from being raised in strong communities of friends, families, and neighbors. Unfortunately, it has become difficult to foster such an environment in our ever-fragmented offline lives, despite our ever-connected online networks. We're working to change that. Allo aims to strengthen local networks of friends, families, and neighbors by giving them a better way to respond to each other’s needs. With Allo, asking for a favor is no longer awkward and connecting with the right group to find the social and practical support you need is simpler. By making it easier for friends, families, and neighbors to connect, communicate, and coordinate online to help each other offline, we layer in a much-needed element of real-life, real-world interaction and community - something that everyone yearns for and families actually need to get by.
