From their website and Clutch profile

• The homepage claims 3,000+ engineers, 800+ clients and over 25 years in business. The Polish company in KRS dates from 2017 (source).
• The homepage names only two clients, and most case studies describe an unnamed retailer, pharma company or manufacturer (source).
