Vention Reviews & Testimonials

Mobile App Development Review from Lee Tupper
Vention has delivered excellent design prototypes and accurate time estimates. The app is still in beta mode, and the partnership with [...] Vention will [continue] until the release of the next version. Vention is a reliable team that offers quality service. (Verified via email)

Staff Augmentation Review from Jon Wade
Vention’s efforts allowed the successful development of the product, resulting in new customers. They provided backend developers, business analysts, UI designers, and QA testers to develop our solution. Vention cultivated a seamless partnership through constant updates and a collaborative approach. Overall, their team’s well-rounded expertise was impressive.

Web Development Review from AJ Canty
We’ve been working with Vention for quite some time and consider them an extension of our team, rather than an offshore vendor. We needed solid mobile developers to work with our in-house engineers to build our Primer SDKs on both mobile platforms. This was not a trivial thing as it required a lot of cross-functional communication, but the Vention team was up to the challenge. They quickly adopted the best practices we follow at Primer and proved to be effective and proactive.
