We focus on testing and quality engineering for companies that can't afford mistakes. We bring the assurance of quality, 'unlocked' deliverables without depending on our products and services. The earlier we detect errors, the less they cost you. That's why if you involve Tesena from the start of a project, you can reduce costs due to errors by up to 30x. Not to mention the time savings. We offer expert training in testing and quality engineering in the form of tailor-made training for companies, courses and specialised meet-ups.
TIP: If you can't find 'your' course or topic, email us and we'll tailor it for you.
