What Koios does

Koios is a private Croatian IT consulting firm founded in 2008 and headquartered in Zagreb, with a regional office in London. The company specializes in business intelligence, data warehousing, and custom application development for the financial sector, primarily banks in Croatia, the Adriatic region, and — following the 2024 acquisition of UK-based Yard — the United Kingdom. Its core technology stack spans Oracle, SAS, IBM (DB2, SPSS), Microsoft (.NET), Java, Microsoft SQL Server (SSIS/SSRS/SSAS), and the full Atlassian suite; since 2021 it has operated as an Atlassian Gold Solution Partner. Koios delivers data warehouse implementations, regulatory reporting systems (IFRS9, CESOP, XBRL, DORA), credit risk and AML systems, CRM modules, and ESG compliance tooling, including its proprietary AI-powered product Simple ESRS.

The business model is predominantly professional services: project-based consulting engagements with recurring maintenance contracts, supplemented by Atlassian license resale. Go-to-market is enterprise field sales targeting banks and financial institutions, supported by content marketing, conference presence (Money Motion, DSC Adria), and an active Atlassian community meetup series. Recent strategy has combined acquisition-led geographic expansion (Yard in 2024), vertical diversification (telecom, energy), and selective productization (Simple ESRS, a blockchain fund management platform in development). The company has not disclosed funding rounds, appears founder/management-led with an employee stock option program, and reports headcount of roughly 100 across Zagreb and London.
