Agnost AI
Agnost AI is a Y Combinator (S26) startup building product analytics for teams shipping conversational AI agents. It reads every production chat and voice conversation, clusters what users want, where they get stuck, and why they churn, then turns those patterns into evals, debug trails, and automatic pull requests that improve the agent. It installs in three lines of code or via an OpenTelemetry exporter, works with any LLM and framework, and processes over a million events a day for customers including Google, Exa, and Corgi.
Cignara
Cignara builds AI voice and chat agents that run sales and customer support end to end for large B2C enterprises. Instead of answering FAQs, its agents ingest a company's knowledge base, policies, workflows and customer profiles to take governed, policy-bound actions - and to spot upsell, cross-sell and churn moments in the middle of a conversation. Founded by two-time YC founder Nalin Gupta (previously Auro Robotics, acquired by Ridecell), the company launched in Y Combinator's Spring 2026 batch after rebranding from Bujo AI, and counts Fortune 500 brands like LG among its users.
Assembled
Assembled is a San Francisco-based software company building the workforce management and AI agent platform for modern customer support teams. Founded in 2018 by three Stripe veterans, it now helps companies like Stripe, Robinhood, GoFundMe, Etsy, and Intercom forecast demand, schedule agents, and resolve a growing share of tickets with AI across chat, voice, and email.
