  • Activeloop
    Activeloop
    Y Combinator LogoS2018
    Active • 15 employees • Mountain View, CA, USA
    We provide a simple API for creating, storing, versioning, and collaborating on multi-modal AI datasets of any size. With Activeloop's open-core stack, you can rapidly transform and stream data while training models at scale. Deep Lake powers foundational model training by acting as a vector database with significant benefits, such as (1) the ability to use multi-modal datasets to fine-tune your own LLM models, (2) storing both the embeddings and the original data with automatic version control, so no embedding re-computation is needed (3) truly serverless service with no vendor lock-in. How cool is that? GitHub loves us - we're one of the fastest-growing libraries there, and we're used by little-known companies like Google, Waymo, and Intel. No big deal. Our founding team hails from places like Princeton, Stanford, Google, and Tesla, and we're backed by Y Combinator & other Silicon Valley heavyweights. Activeloop is hiring, and we want you! Check out our open roles on our YC page and join the fun. 10-min demo: https://activeloop.wistia.com/medias/aibvo0dst2 Whitepaper: https://www.deeplake.ai/whitepaper

  • Revery AI
    Revery AI
    Y Combinator LogoS2021
    Active • 5 employees • Emeryville, CA, USA
    We are building the TikTok for fashion — a platform for creators to showcase their works, gain traction and build their brands. ### Reverie is powered by two pieces of core technology: - An AI-enhanced design tool for creators to turn their design ideas into e-commerce quality product images very efficiently. - An AI-powered Virtual Dressing Room to create professional fashion photography directly from product images. Both fashion creators and other users can easily style outfits on different models. With our core tech, we are building an active community of fashion creators (designers, stylists, influencers, bloggers, artists, casting directors, etc..) who produce original designs and engaging content around the published pieces. The social media platform will provide a streamlined path for fashion creators to experiment with their ideas and build traction. We want to eventually become the default choice for anyone who wants to launch their fashion label, and have the future Off-White, Balenciaga, Rick Oven, etc. originate from Reverie. Our team combines deep expertise in technology (AI Phds) and the fashion industry (Community builder). Our Virtual Dressing room is live with top retailers (such as Neiman Marcus) and has ~1M ARR. We are backed by YCombinator, TSVC, Cabra VC, and other amazing angels with retail experience and connections. Join us to reshape the fashion industry!

    Adoption of Telehealth 1.0 has dropped to <5% because it's inefficient and unintelligent. Ankr uses generative AI to recreate functions of clinic staff including front desk, medical assistants and scribe. This allows Doctors to "spin-up" virtual clinics on-demand, anytime, anywhere. An average clinic using Ankr generates $1M in new revenue/year. We integrate with all top EHRs and work with all types of clinics in mid- to large-sized healthcare organizations.

    Y Combinator LogoS2020
    Acquired • 12 employees • San Francisco, CA, USA
    ML models are only as good as the datasets they're trained on, and that means that most improvement to model performance comes from improvement to the quality and diversity of their datasets. Our tooling makes it easy for ML teams to find anomalies + failure patterns in their datasets and fix these problems by editing / adding the right data. So the next time you retrain your model, it just gets better.
