Generative AI Startups funded by Y Combinator (YC) in the San Francisco Bay Area 2025

Sapling offers an API and SDK to help businesses integrate language models into their applications. Its messaging assistant sits on top of CRMs and messaging platforms to help users more efficiently compose responses.

HR/IT/Finance professionals spend 50% of their time answering employees' questions and tickets. It’s even worse on the employee side, they have to wait for a long time for simple answers. We are live with 500 customers like Coca-Cola, Sony, Puma, Vodafone, Nestle, P&G, Airbnb, etc. We have raised over $40M from top VCs like Bessemer, Greycroft, Elad Gil, etc. Leena AI consumes company’s enterprise knowledge & starts answering all employee questions just like a human would. It can even answer complex personalized questions like Why is my salary less this month? Employees can access Leena AI from commonly used UIs like MS Teams or Slack.

Orangewood Labs makes the world's most affordable AI-powered industrial robotic arms for small businesses! Our robots can be programmed by just using natural language prompts and cost a fraction of human labor.

Tara AI helps engineering leaders measure and improve engineering efficiency, with fine-tuned, secure LLMs trained on source control and project data. Our customers include MongoDB, Clearbit and Prometric. Our platform generates all-in-one views on cycle times, benchmarks, investments and overall size and velocity of engineering activity. We're helping customers achieve 30% reduction in time to customer deployment.

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.

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

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!

A personal cloud storage platform that's so good, it'll replace Finder / File Explorer on your desktop. Find anything with multi-modal, natural language search. Browse with a lightning fast interface that feels just like native. Organize, tag, view, edit, share, and more.

Boundo uses generative AI to replace SDRs. Tell our platform who you're looking for, and it will find and contact high quality sales leads in a fully automated way! We’ve tuned our models to write near-human outbound sales emails with proven conversion. Best of all, we're using our own tool to do all of our sales.

Let AI turn your ideas into a website in minutes. Get content, structure, and style done for you, ready to edit and publish instantly.

Monterey AI helps companies understand what actions to take to improve engagement and reduce churn by setting up user feedback channels, auto-collecting, and analyzing qualitative feedback and quantitative data from multiple sources.

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.
