The Modern Pricing Engine for Retail

Pricing Strategy is one of the most powerful levers that retailers have at their disposal to create growth, yet it is underleveraged. Most retail pricing teams settle for making decisions in spreadsheets, shooting in the dark, and working backward from a cost-plus margin target, leaving a LOT of money on the table. Our founders experienced these problems at scale when they built pricing tech at Uber that made Uber a billion dollars in profit a year. They realized that retail was lacking the same quality and sophistication of price tooling. So, they built Luca. Luca is an AI-powered co-pilot for retail operators, which constantly identifies revenue and profit headroom, makes recommendations for price adjustments and saves countless work hours along the way. Luca is backed by Y Combinator, Menlo Ventures, and others.

interactive video models

We are building universe simulations powered by interactive video models. We train video models that simulate hyper-realistic environments with immersive control, replacing hard-coded game or physics engines with dynamic neural networks. We built the fastest action-conditioned diffusion video model (running at 20+fps on a 4090 gaming gpu) to simulate minecraft. It is 5x faster than other minecraft World Models and was trained with 100x less resources. Our unique insight was relying on aggressive compression in our tokenizer (128x versus the traditional 8x), and because attention scales quadratically with # of tokens our model can run blindingly faster. Now we’re training a hyper realistic world model!

Lucy Goods, Inc logo

Lucy Goods, Inc

Lucy’s mission is to reduce tobacco-related harm to zero. We provide…

If it isn’t bad enough that smokers don’t realize the scientific facts about nicotine, most non-tobacco nicotine products are poorly designed and unappealing to use. The leading gum is sold like a pharmaceutical drug, with flavoring and packaging to match. Vapes provide a cumbersome, over-the-top experience — with use as tightly restricted as cigarette smoking itself, but more juvenile, conspicuous, and highly addictive. People want, and deserve, a better way. Therefore, we want to deliver nicotine users a superior experience, and at the same time give them a way to transition out of feeling dependent. In a better society, people wouldn’t carry around the sensation that they’re stuck with an involuntary habit. Our mission isn’t to encourage nicotine use among people who haven’t started. Unlike certain vapes or other products, ours isn’t the sort coveted by underage users on social media. Our mission is to alleviate the harm related to tobacco — first and foremost, by switching people away from the most harmful products. So, at Lucy, we take an evidence based view of nicotine. Nicotine’s pleasurable properties make it an inevitable part of modern society. Therefore, minimizing harm in all nicotine products is key, in addition to giving people products and strategies for cessation. We feel that, as 1,300 people are dying of tobacco related illnesses every day in the US, the most important and immediate step toward a better society is giving nicotine consumers products they enjoy using that will cause less harm. Our first product is designed to appeal to smokers and encourage them to switch. And, looking ahead, we hope to secure approval in the future as a clinically proven smoking cessation aid, while continuing to participate in the FDA’s public hearings around how NRTs are best regulated. Our goals are simple: because harm reduction is a better strategy around nicotine delivery than abstinence or prohibition, we want to help improve public health — and reduce its costs — through a superior pure nicotine product.
