SIRETLY

SIRETLY is a B2B data management platform that verifies, enriches, and corrects business information like SIRET identifiers, VAT numbers, and APE codes while detecting duplicates. It resolves data quality issues from migrations and manual entries through a four-step automated process: cleaning and normalizing company data, identifying inactive companies via SIRENE records, validating SIRET, VAT, and APE data against INSEE and DGFiP databases, and detecting duplicates with a proprietary algorithm. Users can resolve ambiguous cases through an online portal, selecting from verified candidates when multiple matches occur. SIRETLY integrates with existing tools and uses official public sources like the INSEE SIRENE database and DGFiP VAT files. Operating on a credit-based model, one credit equals one processed line, valid for one year.

Spectrum Quality

Spectrum Quality extracts, normalizes and standardizes your data with confidence across multiple inputs and formats.

Ideally suited for global client bases with multi-level data standardization and transliteration needs for multiple languages and on culturally specific terms, including those in Arabic, Chinese, Japanese and Korean.

SQACE

SQACE is a web-based low-code platform for testing data and data processes, with all relevant tools for the required data analysis and preparation. The application helps teams ensure data quality in a structured and efficient manner and provides transparent documentation of test activities. Customer projects show that SQACE can significantly reduce the effort required for data-related testing, often by 80% or more compared to previous approaches without the platform. At the same time, test coverage and test depth can be increased. SQACE offers a wide range of visual components that allow users to define and execute data queries, data comparisons, range checks, duplicate checks, and other quality validations. The platform handles many technical considerations in the background, enabling users to focus on the business logic. Data from different sources can be combined, validated, or compared. Based on modular building blocks, complex workflows can be created without programming. Code can be used when needed, for example for more specialized cases. The platform also supports before/after comparisons, regression testing or simple delta analysis. For more complex scenarios, transformation rules can be defined in comprehensible rule sets, which can generate expected results for any data volumes, for example for ETL or data migration tests. These expected results can be compared with actual results, and the platform provides automated support for determining test coverage. SQACE supports both ad-hoc testing and automated test pipelines. The graphical interface allows even experienced SQL users to create queries visually, improving maintainability. Built-in suggestion mechanisms help users formulate tasks quickly, even with only occasional use. Results of tests and comparisons are automatically stored, versioned, and visually prepared. They can be reviewed, re-executed, or reused as data sources for additional analyses. SQACE is containerized and can be deployed flexibly in enterprise environments.
