Installed with a single line of code, it learns from a site's own content to answer visitor questions, qualify leads, and route complex cases to humans. Founded by Ryan Endacott (YC S22), Stella serves small businesses, SaaS companies, and local governments - including the Town of Carmel, NY, where it answered more than 2,400 resident questions and saved staff over 200 hours.
Humata
Humata is an Austin-based AI company that lets people upload files and ask questions about them in plain English, returning answers with clickable citations that point back to the exact passage in the source document. Often described as 'ChatGPT for your files,' it targets professionals in legal, finance, healthcare, and research who need to extract insight from dense, unstructured documents without reading every page. Founded in 2022 by Cyrus Khajvandi and Dan Rasmuson, the company raised a $3.5M seed round in October 2023 led by Google's Gradient Ventures with participation from Cathie Wood's ARK Invest and M13.
QueryPal
QueryPal is a San Francisco-based enterprise AI company building agentic customer-support software that resolves tickets rather than just deflecting them. Founded by Dev Nag - the former founder and CTO of Wavefront (acquired by VMware) - the company turns a company's existing documentation, past tickets and internal systems into an AI layer that drafts email replies, powers self-serve chat and autonomously resolves issues, while keeping SOC 2 Type II and GDPR-grade security. Originally launched as CtrlStack with $5.2M in seed funding co-led by Sequoia Capital and Engineering Capital, QueryPal pitches itself as 'the human knowledge layer for secure AI.'
