What rejustify does
Rejustify S.à r.l. is a Luxembourg-based private company founded in 2019 that operates an AI-powered data reconciliation and ETL platform designed to connect users with more than 600 million data series from 60+ authoritative statistical sources, including Eurostat, the IMF, World Bank, OECD, national statistical offices, central banks, CDIAC, BP Statistical Review, ENTSOE, Johns Hopkins CSSE, ECDC, WHO, and CryptoCompare. The core product is an AI engine that classifies user data structures across dimensions (time, geography, unit, sector, general, number), recommends best-matching sources, and applies six matching algorithms (synonym-proximity, synonym, proximity, time, exact, value-selection) to fill missing values, normalize formats, and reconcile units across heterogeneous datasets. A 'Data Learning' capability accumulates per-user preferences over time to automate subsequent ETL routines, and the engine is exposed through a Google Sheets add-on (Google Workspace Marketplace), an R package (GitHub), and a Python module (PyPi).
The company sells through a product-led growth motion: a free tier with limited API calls and data points leads to a paid Individual tier at €30/month or €180/year, with an Enterprise tier offering unlimited data points, custom integrations, multi-user access, and dedicated training negotiated via direct contact. Target customers are data scientists, quantitative analysts, researchers, academics, and data journalists who need to assemble and reconcile macroeconomic, financial, energy, climate, health, and cryptocurrency data without manual wrangling. The company is founder-led by Vojtech Seman and Marcin Wolski, supported by three named advisors, and maintains partnerships with Founder Institute, LHoFT, Prometheus-X, and The Brain. Headcount is reported at 1–10 employees, no institutional venture funding rounds have been disclosed beyond a 2021 Luxembourg-City Incubator participation, and the company has no named enterprise customers in the available source material.

rejustify competitors and assessment
Company assessmentDirect peers
- Tiingo: Tiingo is a financial data API and research platform offering equities, FX, crypto and fundamentals via REST endpoints with a Python-friendly focus. It targets the same data-scientist/quant persona with a comparable freemium-to-paid tier structure.
- Nasdaq Data Link (formerly Quandl): Nasdaq Data Link is a financial and alternative data marketplace and API that aggregates economic, financial and alternative datasets for institutional and retail quants. It directly competes for the same data-scientist persona and sells through a similar free-plus-paid API commercial model.
- Trading Economics: Trading Economics aggregates economic indicators, forecasts and historical data from official sources worldwide, with an API and premium institutional tier. It competes head-on with rejustify for the same macro-economics, research and trading use cases, and serves overlapping customer segments.
- DBnomics: DBnomics is an open aggregator of economic statistical data from hundreds of official providers (Eurostat, IMF, OECD, central banks). It is the closest open-data analogue to rejustify's catalog-and-reconciliation concept and overlaps directly in target users (researchers, quants, data journalists) and source coverage.
- Alpha Vantage: Alpha Vantage offers a freemium financial data API covering equities, FX, crypto and economic indicators, delivered through REST and SDKs in Python and other languages. It shares rejustify's product-led, self-serve developer GTM and target market of algorithmic traders and data scientists building pipelines.
Emerging players
- FRED (Federal Reserve Economic Data): FRED is the St. Louis Fed's free repository of hundreds of thousands of economic time series with a public API. While not a commercial peer, it is a partial substitute for the catalog side of rejustify's offering and overlaps strongly on persona and source coverage for U.S.-focused users.
- IEX Cloud: IEX Cloud (now part of Tyler Technologies) was a developer-first financial data API serving equities, FX, fundamentals and reference data. It overlaps with rejustify's API-delivered, self-serve model for fintech and data science builders.
Broad incumbents
- Bloomberg Terminal: Bloomberg is the dominant incumbent in financial and economic data for institutional finance. It overlaps with rejustify's macro/financial use cases but at vastly greater scope, price point and locked-in workflow — relevant primarily as a ceiling on enterprise pricing for institutional buyers.
- Databricks: Databricks is a broad data engineering and analytics platform with native connectors to many of the same authoritative sources rejustify covers. It competes indirectly for the data-engineering budget of larger customers but at vastly greater scope (lakehouse, ML, governance) rather than focused statistical reconciliation.
- Refinitiv (LSEG): Refinitiv (now part of LSEG) is one of the largest providers of financial and economic data, analytics and desktop tools (Eikon/Workspace). It competes for the same enterprise analytics budgets as rejustify's Enterprise tier but as part of a much broader data and workflow portfolio.
