Mercor

Mercor is an artificial intelligence hiring startup that connects expert contractors with technology companies for the purpose of training AI models and chatbots. The company, headquartered in San Francisco, was founded in 2023 by Brendan Foody, Adarsh Hiremath, and Surya Midha. Mercor initially developed an AI platform to interview and match freelance programmers with hiring companies before shifting its focus to data labeling for AI training. Its founders, who are Thiel Fellows, were named to the Forbes 30 Under 30 list in 2025. In May 2025, the company appointed Uber's former chief product officer, Sundeep Jain, as its first president.

Open WebUI

Open WebUI is a self-hosted, open-source web interface designed for interacting with locally-run large language models (LLMs). It provides users with a customizable alternative to proprietary chatbot interfaces, allowing for greater control over data privacy and model integration. The platform supports a wide range of open-source LLMs and is noted for its modular design, which facilitates community-driven extensions and integrations. Its development is a response to the growing demand for private, customizable AI interaction tools outside of cloud-based services. As a self-hosted solution, it enables deployment on personal hardware or private servers. Recent development activity indicates a focus on expanding its model support and feature set within the open-source AI ecosystem.
