Every business leader knows that good communication, both internal and external, is essential to success. However, while companies often spend big budgets on customer-facing communications, inter-office communication tools are still dominated by a 30-year-old technology: email. KrestIOC is the rare software that is powerful, extremely easy to use, and seamlessly blends into our workflow. It has helped keep our whole team on track with our messaging and up to date. The software is also supported by a professional and very responsive support team. Would highly recommend KrestIOC for any team. Apps like Skype and Whatsapp are replacing email for quick soundbites and notes like “want me to get you a coffee?” These applications can be convenient, but not necessarily built for professional use. You also run the risk of staffers doing more personal communication with their personal network than their office network, since both of these platforms are open to anyone.
