# Fulcrum Genomics vs Pepkio: Bioinformatics Service Comparison

The practical difference between Pepkio and Fulcrum Genomics is whether your project needs fixed-scope data analysis with raw R and Python script delivery, or custom software engineering and production pipeline development. Both teams are dry-lab computational biology partners. They accept raw data from external sequencing providers and do not run in-house wet labs. Pepkio focuses on core omics datasets and provides executable R and Python scripts, optional Nextflow or Snakemake workflows, optional Docker or Conda containers, editable vector figures, and communication with lead bioinformaticians. Standard turnarounds are 2 to 4 weeks. Fulcrum Genomics focuses on custom bioinformatic software engineering, duplex and simplex Unique Molecular Identifier (UMI) consensus processing (`fgbio`, `fgumi`), clinical CAP/CLIA assay validation, and enterprise Nextflow or WDL workflows. Pepkio may fit better if you want fixed-price study execution and raw analysis scripts. Fulcrum Genomics may fit better if you are building proprietary pipelines, clinical NGS assays, or custom error-corrected sequencing tools.
