About
Talus Bioscience is a Seattle-based AI-powered drug discovery company targeting transcription factors — the class of proteins historically considered "undruggable" that regulate gene expression and drive many cancers — using its proprietary MARMOT platform (MAssive Regulome Mapping Of Transcriptomes) to measure the binding activity of small molecules across 10,000+ regulomes monthly using live, unmodified human cells. Founded and backed by Y Combinator (W21) with $11.2 million in Seed+ funding raised in August 2024, Talus received FDA and EMA approval for Phase I human trials of its lead program MSD-001 in 2024 — advancing toward first-in-human studies for a transcription factor-targeted cancer therapy.

About
Grok is the AI assistant developed by xAI, Elon Musk's AI company founded in 2023, and distributed primarily through X (formerly Twitter). Grok launched in November 2023 as an X Premium perk, with the notable differentiator of real-time access to X posts and a less restricted, more direct conversational style. Grok 3, released in February 2025, achieved top scores on the AIME math reasoning benchmark and ARC-AGI test, briefly positioning xAI as a frontier model lab.
