Fern, operating under the entity Ishiki Labs, is a Y Combinator W26 company building an AI meeting assistant for high-stakes conversations. The product runs in two modes: as a visible participant that offers real-time opinions and research, or as an invisible copilot that delivers live summaries and contextual insights. It targets founders, account executives, and recruiters who need in-the-moment intelligence during calls. The company was founded in 2025 by two former Meta researchers.
