    Krzysztof and the PrimeModule team get it. We have worked together on two web app projects over the last year, and the team has been responsive, responsible, and effective. Despite being a young company, the team is professional and takes every aspect of the project with due care. I have already recommended Primemodule to a couple of my close entrepreneur friends and would do more.

    1000 Cookbooks worked with Primemodule to deliver a consumer-focused mobile-friendly web app on a tight deadline. The Primemodule team delivered a great service across the whole project from UI design, through development and testing, to final deployment and post-launch updates. The founders Marcin and Krzystof were always available and responsive, and displayed a real commitment to ensuring we delivered a great product on time. Overall, Primemodule are an extremely impressive operation and I can recommend them without hesitation.
