Evidant Data Transform Refinery (DTR)

The Evidant Data Transform Refinery (DTR) is a code-free, streaming business transformation platform that converts raw operational data into analytics-ready data that is Valid, Valuable, Accurate, and Fast. Unlike ETL tools — which are designed for data movement and generic transformation — the DTR is purpose-built for the hardest problem in enterprise analytics: converting raw operational process data into data that directly represents how the business operates. This includes audit trails, application logs, event logs, workflow data, and timestamped operational records from any source system. Business analysts build Refineries — data transformation pipelines — directly in the DTR's visual, rules-based UI without writing any code. The person who understands the operations builds the data. No IT ticket. No engineering handoff. No rework cycle. The DTR processes data as a streaming platform — data is never stored in a database. It connects to any source: databases, REST APIs, application logs, FTP, flat files, ERP systems, MES systems, and streaming data. Output goes to any BI tool, dashboard, or analytics destination. The DTR includes ten purpose-built transformers, each designed for a specific class of operational data problem that generic tools cannot address. The DTR produces data across seven farm types aligned with BPM standards: Activity, Task, Subtask, Behavior (timestamped event data), and Case, Master, and User (current state data). Every node in a Refinery is color-coded by its output farm type, making any Refinery readable at a glance. Analytics outputs supported: productivity metrics, operational analytics, workforce management, compliance and control, process analytics and process mining, and any BI tool or dashboard. The DTR is not an ETL tool. It is a Business Transformation tool — designed specifically to produce data that the business can trust, understand, and act on.

Foursquare Spatial H3 Hub

FSQ Spatial H3 Hub eliminates traditional barriers to geospatial data adoption in traditional ML models by providing data scientists with analysis-ready datasets that do not require specialized geospatial tools or expertise. Datasets containing information in raster and vector formats are converted to tabular form and indexed to H3 cells. This allows data scientists to easily enrich their own datasets, containing attributes like lat/long coordinates, city names, or zip codes, by joining on a common H3 index. Built on DataHub‘s enterprise metadata management system, the platform ensures data lineage tracking, versioning, and governance capabilities that enterprise data teams require. This foundation enables the first offering in the FSQ Spatial H3 Hub: an Iceberg Catalog that offers 20+ open datasets pre-indexed to H3 cells at resolution 8, made available in a free preview. Data scientists can access this catalog from their framework of choice (Spark, Python, DuckDB) and augment their ML models with a rich array of spatial features.
