What StangaOne1 does

Stanga is a Sofia, Bulgaria-headquartered custom software development and IT services company founded in 1999, operating as a subsidiary of the publicly listed ONE Technologies group (over 10,000 experts, $1B+ group revenue). The company delivers across nine service practices — Team Extension (Dedicated Teams, Staff Augmentation, Managed Projects), Custom Development (web, mobile, blockchain, QA), AI Services & Implementation, Strategy & Consulting, Design Services, IT Infrastructure & Operations, Big Data Integrations, Smart Platforms & Automation, and Digital Marketing Assets — and maintains 450+ engineering staff distributed across six R&D centers in Bulgaria, Serbia, Ukraine, Poland, Romania, and Georgia, with regional offices in Petach Tikva (Israel) and Miami (USA).

The company's technology stack spans AWS, Azure, and Google Cloud; enterprise platforms (SAP, Oracle, NetSuite, Microsoft Dynamics 365, Salesforce, ServiceNow, Sitecore, Adobe Experience Manager); and integration partners including Shopify, Stripe, and Contentful. Stanga holds tier-1 vendor accreditations (Microsoft Gold, Oracle Gold, AWS) and maintains ISO 9001, ISO 27001, GDPR, and PCI DSS Level 1 compliance. Its sole proprietary product is SiSO Suite, an AI-powered M&A deal management platform (SiSO Diligence, SiSO Pipeline, SiSO Budget Tracker, SiSO Copilot) built on OpenAI models. The firm sells predominantly to enterprise clients via direct sales and staff augmentation; named customers include Imperva, Volkswagen, McDonald's, Monday.com, Bridgestone, and Amadeus.

Revenue mechanics rest on three engagement models: multi-year dedicated teams, fixed-budget staff augmentation with milestone billing, and managed projects with flexible scope. The go-to-market is enterprise field sales targeting the US, Israel, Germany, France, UK, and Scandinavia. Acquisition history (51% of Infoleven in December 2021 for DACH access; 70% of Go Interactive in February 2026 for North America) indicates an active geographic roll-up strategy funded through the parent group.
