      Mobile App Development Review from Max Levchin

      We've partnered with HDWEBSOFT who have created our app using .NET. The feedback from our customers we've received has been overwhelmingly good. We had heard positive things about the idea even before we released the app, so it's encouraging to see those comments continue once it has been out. HDWEBSOFT was set up from the start. The design team was outstanding; they completed the job on schedule and within our allocated budget. They followed a well-defined procedure that was in place.

      Paul Cummings's Review Sourced from Google

      Beehive Software is simply the best technology partner I have ever worked with. What started as a limited bespoke consumer mobile app SOW quickly grew into more full-scale consumer digital experience support. At the time of this writing, Beehive has delivered 3 major mobile app upgrades for Blue Zones, developed an Online Assessment Portal to support health and wellness survey delivery, and delivered an Analytics PaaS for our enterprise. We have been extremely fortunate to work with top talent like Yaron Hadad and Mor Yariv on our project; their leadership, creativity and partnership IQ have been through the roof. Whether a startup, mid-size, or enterprise-grade customer, Beehive's model allows for scale and delivery support that is really unprecedented in terms of both resource quantity and quality; and it is elastic in a way that benefits their partners. They're really just the bee's knees (pun intended) - and any partner looking to develop exciting and engaging consumer experiences, science-based health and wellness experiences, end-to-end data capture and analytics experiences... hell, *any* experience... would be well-served to consider Beehive Software to be their partner.

      Jonathan Faran's Review Sourced from Google

      Beehive Software is probably the best solution you can get. First of all, the core team - led by Yaron - is one of the most professional in the market, guaranteed. Second, their dedication to delivering an exceptional product on time is truly impressive. Their responsiveness alone speaks volumes. The system they’ve built is also incredibly unique, offering a brilliant way to make development not only faster but also significantly more cost-effective. We've used both their products and services across different parts of our development process, and they’ve proven to be outstanding. We highly recommend Beehive Software to anyone - from small startups to large companies - who want to avoid hiring an entire dev team and instead use a smart, ready-made solution.
