K36 Therapeutics, Inc.
K36 Therapeutics is a Cambridge, Massachusetts clinical-stage biotech developing first-in-class oral small-molecule inhibitors of NSD2/MMSET, an epigenetic enzyme that drives hard-to-treat cancers. Its lead candidate, gintemetostat (KTX-1001), is in Phase 1 for relapsed/refractory multiple myeloma carrying the t(4;14) translocation, and a second program, KTX-2001, targets metastatic castration-resistant prostate cancer. Backed by Atlas Venture, F-Prime Capital, Eight Roads Ventures, Nextech Invest and Bristol Myers Squibb, K36 has raised roughly $100M+ to translate chromatin biology into precision cancer medicines.
Aqtual, Inc.
Aqtual, Inc. is a Hayward, California precision medicine company that reads epigenetics, gene regulation and transcriptomics from a single blood draw. Its proprietary active-chromatin cell-free DNA (cfDNA) platform captures circulating chromatin to survey hundreds of thousands of regulatory sites, integrating DNA, epigenetic regulation and protein-DNA binding in one blood-based assay. The company is first commercializing a test that predicts which therapy will work for rheumatoid arthritis patients, with a broader pipeline spanning oncology, immunology, cardiovascular, metabolic and neurological disease. Aqtual has raised roughly $47M to date, including a $31M Series B in July 2025.
Arima Genomics
Arima Genomics is a Carlsbad, California biotech commercializing Hi-C technology - sequencing methods that reveal the 3D structure of the genome. Its research kits help scientists assemble chromosome-scale genomes and study chromatin architecture, while its clinical brand Aventa Genomics turns the same proximity-ligation chemistry into FFPE-friendly cancer tests for fusions, rearrangements, and other structural variants conventional NGS often misses.
