The core team is responsible for creating new application to support the companys evolution forward, as well as supporting the present applications in production.

    Rikard Hohlfält

    We are very happy that Rikard choose to do his internship at JellyHive!
    Rikard has built a solution around an IoT device that enables you to pay for usage of electrical devices.

    Our CEO Jonas W has supervised and is impressed of what Rikard has managed to produce in a such a short time. Hopefully Rikard comes back to us for his second internship in the spring of 2019

  • JellyHive delivers to VCRS
    Bilia and the sky

    One of our developers, Jonas P, has after the summer started a new assignment at VCRS, Volvo Cars Retail Service. He will support a newly formed small team to take one of their products to new heights. The technology stack consists of: Angular 7, dotnet core 2.1, docker and azure.

    The team is quite small, five persons, but the production speed is high. There’s a lot happening, which is very interesting and fun.

  • Thank you for the party!

  • We're transforming

    Advise Solutions was founded in 2010 with the intention of creating a company focused on the consultants and to offer a better chance of managing their own careers. There is a striking difference how much you can affect your situation and how involved you can be in a small consultant company compared to the big and impersonal companies. Our focus has always been to grow but grow with dignity and with the focus on keeping the small company culture.

    Over the years, the company has evolved and today we are something more. New colleagues have joined, and we have refined our corporate culture and corporate identity that we no longer could find in our old company name.

    To create a new name and profile, we needed to go from inside and out. We formulated what values we have as employees and the corporate culture that now exists in the company. This work resulted in the company’s key values, which in turn formulated our name, colors and profile.

    We are proud of this change and our new profile and it also means a start of a new great journey for us. On this journey, we’d like to see more people, maybe you?
