What Quality House does
Quality House Ltd. is a Sofia-headquartered software testing and QA services firm founded in 2004 by Mitko Mitev. The company operates three revenue streams: Testing as a Service (QA outsourcing) that extends client QA teams or delivers adaptable QA Packages; QA Consultancy covering test automation, process establishment, and QA assessments; and Professional Training Courses comprising ISTQB-accredited curricula delivered across Foundation, Advanced, and Specialist levels, plus IREB CPRE, Scrum Master, and Accessibility Testing courses. Its geographic footprint is regional rather than global, with wholly-owned subsidiaries and offices in Bulgaria (Sofia, Burgas), Serbia (Novi Sad), and Romania (Bucharest), making it the dominant QA-focused services provider in South East Europe.
Underlying assets supporting this offering include ISTQB Platinum Partner status held for seven or more consecutive years (the sole accredited training provider in SEE since 2005), ISO 9001:2015 certification, and the SEETEST conference — the only Software Testing conference in the region — co-organized with SEETB. The company maintains a certified workforce of ISTQB-trained testers who also practice on client engagements, and its trainers double as active software practitioners.
The business model is pure professional services: revenue is generated through project-based outsourcing and consultancy engagements (quote-based, no public pricing), plus per-course fees for public sessions, custom corporate training, and on-site courses. Go-to-market combines enterprise field sales targeting IT companies of all sizes with event-driven demand generation through SEETEST (200+ participants), a quarterly Quality Matters magazine, and self-serve online booking for course registration. Customer concentration is distributed across Banking (OTP Bank, Addiko Bank), Telecom (VIVACOM), Technology (Siemens Bulgaria, Micro Focus, Experian, Amdocs, Atos, Wacom), Automotive (Visteon), E-commerce, and Media, with named case studies from SMG Swiss Marketplace Group and OTP Bank Serbia. Quality House is founder-owned with no disclosed institutional funding beyond a non-dilutive EU grant in 2016 for training management software.
