How it works

Dataland

Dataland is a unified data workspace specifically intended for frontline, operational users – like supply chain, logistics, operations, and customer support. Dataland centralizes all data into one place, so business users can ask AI, search, analyze, and take actions against data in one place. Business teams use Dataland to get a 360-degree view of all the data they need for their day-to-day workflows. Here’s how Dataland works: Real-time Data Sync: Dataland has built-in connectors to databases, data warehouses, SaaS APIs, and custom sources. Unlike traditional data integration tools, Dataland live-updates in real-time from its source systems, which is necessary for operational use cases. Universal Search: Dataland indexes the data in real-time and enables operational users to quickly search for up-to-date information across all attributes in all data sources. This enables users to quickly get the full context they need without having to know where to look or to use inflexible tools that can only look up information in specific pre-defined ways. 360-Degree Views: Dataland combines information from fragmented data sources into unified views that provide the complete 360-degree picture of every business entity. This eliminates the need for users to jump across multiple tools. AI Data Assistant: Users can ask AI to analyze data for them, without knowing SQL. Automations and Alerts: Custom business actions can be made available to operational users (e.g. triggering a Zapier automation, hitting an internal API, executing SQL updates, etc.) so they can complete end-to-end workflows in Dataland without ever having to leave the platform. Users can also define alerts through a simple interface without knowing code.

DataMarket

DataMarket is a data marketplace and data discovery solution within the RightData platform. It provides a centralized place where datasets and data products are organized, documented, and made available for use across teams, with defined access controls. Users can search and browse available data, view metadata, and understand what the data represents before requesting access. This helps them assess whether a dataset is relevant for their use case without relying on back-and-forth with data teams. Access requests follow approval workflows based on organizational policies, and records are maintained for audit and tracking purposes. DataMarket brings together data cataloging, data discovery, and access management in a single interface. Datasets are structured and categorized so they can be located and understood more easily. By standardizing how data is published and accessed, it reduces inconsistencies in how different teams interact with data. The platform supports data democratization by allowing more users across the organization to find and use data independently, while still operating within governance and security boundaries. This reduces dependency on data engineers for routine access and helps teams move faster on reporting and analysis tasks. DataMarket is used by business users, analysts, and data scientists who need access to data for reporting, analysis, and decision-making. It is also used by data engineers and data owners to publish, organize, and manage datasets so they can be accessed by others in a controlled manner.

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.

Herus

Herus is a modern data catalog designed to help teams organize, discover, understand and govern their data faster. The platform integrates with your data stack to import metadata, semantic definitions, lineage, usage insights and data processing code. It can also push field descriptions back to databases as native SQL comments. Users can explore data through an intuitive interface, advanced SQL-like filters or AI-powered search. They can navigate table and field lineage end-to-end, trace data back to its sources, and understand how it flows into downstream dashboards and analytics. Herus uses AI to reduce manual documentation work by suggesting business definitions, inferring lineage and enabling natural language interactions within the catalog. All AI-generated suggestions remain fully reviewable before validation, keeping teams in control. Beyond cataloging existing assets, Herus includes a collaborative data board where analysts and engineers can visually design transformations. Based on these designs, AI can automatically generate complete written specifications, reducing duplicated work across documentation tools and wikis.
