Sentieon builds ultra-fast, highly accurate software for analyzing DNA and RNA sequencing data. Its pipelines - DNAseq, DNAscope, TNseq, and TNscope - replace the open-source GATK workflow with matching or better accuracy while running many times faster on ordinary CPUs, no specialized hardware required. Founded in 2014 and based in the Bay Area, the company has won top honors in multiple precisionFDA and DREAM challenges, and its tools are used by pharma, clinical labs, sequencing platform makers, and genomics researchers worldwide to turn raw reads into trustworthy variant calls quickly and cheaply.
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.
Tom Willis, PhD, is a genomics entrepreneur with more than 20 years of company-building experience who became CEO of Arima Genomics in June 2025. A Yale and Stanford physicist turned biotech serial founder, he co-invented Molecular Inversion Probe technology, built two genomics companies from the ground up - ParAllele BioScience (acquired by Affymetrix) and Sequenta (whose ClonoSEQ assay became NCCN-standard for leukemia and lymphoma residual disease testing) - then spent a decade as Venture Partner at Illumina Ventures before stepping in to lead Arima, a company pioneering 3D genomics for cancer diagnostics.
