SOTERI SKIN

D2C Skincare for Eczema

Soteri Skin is D2C skincare for chronic skin conditions like eczema. We’re the only non-prescription product proven to provide long-lasting relief for the 30 million Americans who suffer from eczema. How it works: Skin surface pH is constantly in flux, and many of your daily activities can throw it out of balance. People with chronic skin conditions such as eczema have a harder time regulating their skin's pH. Soteri's patented pH/LOCK™ locks skin in at a therapeutic pH for 12+ hours, which is shown to help break the cycle of skin sensitivity, whether you have eczema, psoriasis, or just a bad sunburn. Our formulations are aesthetically elegant (non-sticky, sit well under makeup, etc), safe for anyone to use, and don't require a prescription. Most people see skin health improvements within the first few weeks of application, even for tricky, chronic skin conditions like eczema and psoriasis. With Soteri Skin, anyone can enjoy healthy, glowing, pH-enomenal skin!

SafetyKit logo

SafetyKit

AI agents for risk, compliance, and safety

SafetyKit's AI agents do the dirty work for big tech and finance companies so humans don't have to. Today companies rely on armies of low-paid outsourced humans to protect their platforms from fraud, harassment, and crime. It’s super important work, but the jobs are difficult and sometimes traumatizing, and it’s impossible to keep up. Our mission is to end this manual toil. We learned this domain first-hand at Stripe and Airbnb, where first we built software for human reviewers, and then built models to replace them. We’re a group of engineers from Stripe, Meta, Netflix, MIT, and Princeton that love language models and unironically love B2B SaaS. We know the economy is going to be rearranged over the next 4 years and we want to be in the driver’s seat. We build vertical AI that works and have some of the world’s largest companies as paying customers. Patreon, Eventbrite, Upwork, Character.ai, Substack, Faire, along with a $10B+ marketplace, a $100B+ payments company, and more rely on SafetyKit in production.

Sage AI logo

Sage AI

Your self-generating, self-maintaining code knowledge base.

Sage is a self-generating, self-maintaining knowledge base for your code with in-built chat, accelerating expertise, and comprehension of any codebase. Documentation is perpetually stale, codebases become increasingly old, large, and complex, and knowledge remains siloed within individuals and teams. As a result, engineers take 8-12 months to become fully operational, enterprise code becomes slow and unmaintainable, and core knowledge is continually lost upon engineer turnover. Sage is changing this reality. We take your code and automatically generate a symbol-level knowledge base that self-updates to remain forever fresh. We integrate with source control to pull your code and generate a symbolic graph representation of functions, classes, interfaces, types, etc., automatically determining the relevant context for each symbol, and using LLMs to annotate and propagate documentation via traversals of the symbol graph. Sage revolutionizes the way teams and individuals interact with and understand their code, ensuring that knowledge is always accessible, up-to-date, and interactive.
