Three11

What Three11 does

Three11 is a full-stack digital agency headquartered in Varna, Bulgaria, operating as a custom software development and product engineering services provider. The firm offers four core service lines: Web Development, Hybrid App Development (with React Native for cross-platform iOS/Android delivery), Product Development (concept through launch), and Team Augmentation. Its underlying technology stack centers on React Native for mobile, with broader custom software development capabilities emphasizing security, reliability, and performance.

Three11 serves a horizontal mix of enterprise and growth-stage clients across multiple industries. Named enterprise engagements include E.ON Home (a Home Energy Management System deployed across 7 countries) and the Payslip Global Payroll Control Platform (leveraging AI-powered automation for multinational payroll). Startup-stage client work includes Social Capital (a personal social capital mapping app), Fertility Journey, and a Custom CPMS (Charging Point Management System) for EV infrastructure. The firm's revenue model is professional services / project-based, with quote-based pricing negotiated per engagement and no publicly disclosed rate cards.

The go-to-market motion is sales-led, relying on direct outreach via the company website (three-11.com) and email ([email protected]). There are no disclosed partnerships, channel relationships, marketing automation, or social media presence. The company reports 5 employees, which is inconsistent with the scope of named enterprise projects and suggests a heavy reliance on a flexible contractor or subcontractor bench. The firm claims "a decade of expertise" despite a 2017 founding date, and as of 2025 maintains an active operating presence.
