YCombinator

AI nutrition coach in your pocket

Napkin Math is the personalized AI food journal that people love to use. We gamify nutrition tracking so people are 2x more likely to stick with us than other trackers. Claire, Manuel, and I (best friends for 10 years from MIT) are obsessed with how we can make nutrition fun, and turn fun into health outcomes. === Existing consumer health apps focus on scaling a one-size-fits-all solution: calorie deficits. But they don’t answer the questions you actually have. Food is deeply personal, and so is Napkin Math: Get the fuel you need for marathon training, while understanding you eat catered office lunches five days a week. Discover what’s triggering your stomach irritation, without sacrificing your weekly dinner with friends. Napkin Math tailors a plan for not only your specific health goal, but also your life.

Nasdisc

A marketplace for vinyl, cassettes and cds

Nasdisc is a marketplace for the $4B worth of records purchased every year. The vinyl market has seen exponential growth in the past decade - the first 6 months of this year has already seen an increase of 108% in sales. Our platform takes a 12% cut, making this a $400mm opportunity that is more than doubling every year. Pressing plants are backed up years out, bots buy limited releases in seconds, and record prices are skyrocketing in both retail and aftermarket sales. Despite this growth, the only dedicated marketplace is difficult to use, doesn’t process transactions, yet facilitates over $600mm in vinyl exchanges per year. This is why I finally decided to quit my job at Google and recruit my best friends from college to fix it. We’re all software engineers and have been passionate about music and vinyl since we were kids, and have $50k in records ourselves. We started building a marketplace in July and launched our website 4 weeks ago. We now have $1k / week in sales, and $50k in listings.

Last mile is a $500B industry powering digital commerce but managed largely with self managed API integrations.

Doing this enables merchants and customers to capture immense efficiencies, drive better customer experience, reliability and business outcomes.

Nash was founded in 2021 by Mahmoud Ghulman (2x Founder, MIT) and Aziz Alghunaim (2x Founder, 2x YC, Ex-Palantir, MIT) and has raised funding from top investors, including Y-Combinator and a16z, to build the world’s best logistics infrastructure platform.

YCombinator

Building AGI that can innovate.

Ndea is building frontier AI systems that blend intuitive pattern recognition and formal reasoning into a unified architecture. # AI for Scientific Advancement Unlike all life before us, humanity's ascent is a story of ingenuity, not just biological evolution. Our progress has been driven by the curiosity to acquire knowledge, the ability to pass it on, and an intrinsic drive to innovate. We build technology which gives us leverage beyond our biology. We stand at the top of a knowledge and technology colossus that we collectively created over the past ten thousand generations. Scientific progress has helped us overcome burdens that long defined human life — famines, plagues, and widespread illiteracy. Science will continue to redefine the boundaries of the human condition. Today, the acceleration of scientific progress hinges on one factor: AI capable of independent invention and discovery. This capacity is the gateway to advancements beyond our wildest imagination. # A New Research Lab We're starting Ndea — an AI research and science lab. The name - like 'idea' with an 'n' - is inspired by the Greek concepts ennoia (intuitive understanding) and dianoia (logical reasoning), capturing our first goal to merge deep learning with program synthesis. Ndea is entirely focused on developing and operationalizing AGI to realize unprecedented scientific progress in our lifetime for the benefit of all current and future generations. Building AGI alone is a monumental undertaking, but our mission is even bigger. We're creating a factory for rapid scientific advancement — a factory capable of inventing and commercializing N ideas. From our vantage point today, we see many 'known' frontiers like self-driving vehicles, drug discovery, sustainable energy, robotics, and space exploration. While AGI will benefit all of these, the most exciting adventure lies in the 'unknown'. AGI promises discoveries and progress we cannot imagine today.
