About
Isabl is a New York-based whole-genome and transcriptome cancer diagnostics company — backed by Y Combinator (W20) with $5 million in total funding including $3 million from Two Sigma Ventures, BoxOne Ventures, Bossa Invest, and Jude Gomilla, plus a $2 million SBIR grant from the National Cancer Institute (NCI) — commercializing the Isabl GxT (Genome x Transcriptome) diagnostic platform that received FDA Breakthrough Device Designation for comprehensive tumor profiling that analyzes entire tumor genomes and transcriptomes simultaneously to identify cancer-associated mutations, fusion genes, and expression patterns that guide treatment selection. Founded in 2020 after incubating at Memorial Sloan Kettering Cancer Center (MSKCC) from 2015-2019, Isabl's genomic testing platform is specifically advancing through March 2025 NCI funding for pediatric and rare solid cancers where comprehensive genomic profiling can identify targeted therapy opportunities that standard panel tests miss.

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.
