Mission: Be the compute platform for AGI and make AI better, faster, and cheaper by building more powerful hardware. Approach: We target just LLMs, whereas GPUs target all ML models.

daydream is a platform that automates programmatic SEO, end-to-end. The platform helps businesses identify search patterns, creates content at scale, and automatically improves that content. We've raised $2.5M from leading investors like Basis Set Ventures, WndrCo, SOMA Capital and current and former Heads of Growth/Product Growth at companies like Notion, Airtable, Webflow and Dropbox. Our customers include Product Hunt, Notion, Tome and other venture-backed companies. We're on a high-growth trajectory and we're looking for people who want to join us on the journey to building a billion-dollar company. Our team previously worked together at Flixed, a startup we bootstrapped to $2M+ in revenue almost purely on the back of programmatic SEO.

We believe that the world's decisions can be made by markets. To make that a reality, we're building the world's first platform for creating and trading decision markets. It's like Polymarket but for decision markets.

Measuring model ability is the most challenging part of creating applications that are capable of automating any given part of the economy. There are no good techniques or benchmarks for evaluating LLM performance on business-relevant tasks, so adoption for enterprise production settings has been limited (see Wittgenstein’s ruler). This problem materializes in each place where LLMs have potential: in understanding whether the AI tool companies are building a product will satisfy a customer demand, determining how feasible models and vendors are for a given enterprise in making purchasing decisions, for researchers who need a north star to which to expand model ability. Today, answering these questions amounts to hiring a human review team to manually evaluate model outputs. This is prohibitively expensive and slow. Vals AI is building the enterprise benchmark of LLM and LLM apps on real-world business tasks. In doing so we are creating the infrastructure + certification to automatically audit LLM applications, verifying they are ready for consumption. We've raised mid-seven figures from some of the top institutional investors and strategic angels in Silicon Valley.

Our mission is simple -- we help teenagers build life-changing habits through psychology, technology, and near-peer mentorship. Here are some of our founding beliefs and insights: - Being a teenager is more difficult than ever in the age of social media, video games, post-COVID learning, etc. Students often don’t have a support system to help them navigate this especially given the national shortage of teachers and educators, a lack of mental health resources, and a private education market that is largely inaccessible to the average family only compounds the problem. - Parents want their students to unlock their full potential and become the best version of themselves. However, they don’t want to ruin the relationship they have with their students or may not have the time to be the “micromanagers” of their student’s schedules. - The idea of near-peer mentorship is fundamental to unlocking a student’s long-term intrinsic motivation because the mentor can: 1. Relate to the student and their interests 2. Probably played the same video games and also grew up in the age of social media 3. Has a more mature perspective and can act as an older brother or sister These are our guiding beliefs, and our goal is to create psychology-backed technology that genuinely helps our mentors better connect with students. We believe in a world where AI and technology are used in conjunction with human connection to create incredible real-world changes.

StimScience, the company using personalized neuroscience to improve sleep, is the developer of the revolutionary new consumer sleep aid, Somnee. Somnee is the first-ever electronic sleep aid headband to use personalized non-invasive brain stimulation to improve the wearer’s sleep quality. In a 1,500 night home pilot study, Somnee cut the time it took beta users to fall asleep in half, and it reduced the amount of overnight tossing and turning by more than one-third.
