Examples of our work


Navigating change together.

Digital transformation is rich with opportunity. But these exciting possibilities come with challenges. Everything around us is changing and becoming more complex. What was true yesterday is already obsolete today.

People and companies have been forced to rise to the occasion. Unfortunately, there’s no one-size-fits-all solution or instruction manual. No quick or simple solutions to complex problems. It’s time to travel off of the beaten path and into unfamiliar territory. All so we can find fresh ideas and individual solutions.

This is a mission best tackled together. You get by with a little help from your friends, right? For successful collaboration, you need the right environment. One that fosters free and creative thinking — where people feel comfortable taking risks.

Welcome to Big Sun.
A safe space for your business.

Way of work

The methods behind the madness.

To innovate, you have to think outside the box. That’s why we welcome reflection and encourage experimentation. We know arriving at better solutions is all about asking the right questions. And looking at things from different angles can bring about meaningful change. New ideas are yours to discover if you keep an open mind.

We’re human-centric to the core. Creating opportunities and unleashing creativity means putting people first. Our clients and their customers. Our employees and our partners.

For each new project, we rely on the combined experience and expertise of our team. Everyone brings something different and valuable to the table. And it’s applied exactly where needed — from strategy and concept to design and production.

Our clients are involved in the project from the get-go. Together, we develop an approach that works for everyone. One that doesn’t just leave you with a solution. But the best possible one.

is an attitude.

  • Planning

    • Brand Strategy & Development
    • UX & Digital Content Strategy
    • Digital Transformation Strategy
    • Roadmaps & Guidance
    • Project Development & Management

    It takes a lot of courage and trust to do something new. Having a good game plan doesn’t hurt either.

    That’s why determining what the actual challenge is together with our clients is so important. It’s what sets the course and baseline of any collaboration. Whether web project, campaign, brand development, or your company’s digital transformation.

    From there, we define workflows and overall conditions. And if a project calls for it, we decide which partners to bring in on the action.

  • Design

    • CI & CD Development
    • UX & Prototyping
    • Design Systems & Guidelines
    • Interaction Pattern & Service Design

    Good ideas come in all shapes and sizes. And the creators are just as varied as the work results.

    Our experience ranges from classic project business, campaigns and apps to digital products and services. For us, ideas alone are not enough; we build products to bring the idea to life. This allows us to work through any kinks in UX, design, or programming on a functional prototype. Our motto here: Review. Refine. Repeat.

    Because we believe that experimenting and testing bring us further than lengthy discussions.

  • Production

    • Editorial & Social Media Services
    • Video, Photo & Audio Production
    • Event & Live Communication
    • Campaigning & Social Advertising
    • Web Application & Backend Development

    Each idea deserves its time to shine! That’s why we guide each project from the initial workshop up to the final result. Campaigns, social media, video, live events, or apps. We approach each production with composure and an eye for detail. And if necessary, we can tap into our extensive network of experienced specialists at any time.

    Because in the end, we not only strive for the best result, but the best possible way to achieve it.

  • Improvement

    • Benchmarking & Market Analysis
    • Site Audits & Usability Reviews
    • Personas & User Research
    • Social Data Research
    • Testing & Evaluation

    We’re in it for the long haul. Our clients can count on us to support and guide them throughout our mutual project. Now and in the future.
    Evaluating data helps us identify development potential and to continuously improve the results of our work together.

    The end is just the beginning. Completing a project doesn’t mean it’s over. We believe that you should never stop bettering yourself — especially when it comes to our work.


Open. Honest. Genuine.

We say what we think. And do what we say. Sometimes, this involves saying “no”. All the more reason to appreciate the clients who said “yes” to us:

  • Deutsche Hospitality
  • GC-Group
  • Gesellschaft für int. Zusammenarbeit
  • Kühne + Nagel
  • Net Cologne

Dreamers, Doers, Believers and Thinkers

Big Sun is more than an agency. It’s a space where people can come together. A place that encourages asking questions and exchanging ideas. A chance to think outside the box and be bold. Where ideas are heard and thoughts appreciated. Where actions matter.

We love what we do and created a culture that lets us work the way we’ve always wanted to. Naturally, people are at the centre of everything. Our clients, partners, and colleagues. That’s why we’d like to take a moment to introduce ourselves.

11. Use of Google Analytics

Based on our legitimate interests pursuant to Art. 6, 1 (f) GDPR, we use Google Analytics for the purpose of analysis. Our legitimate interests here are the needs-appropriate design and ongoing optimisation of our website. This applies in particular since our visitors’ data are anonymised and we do not create user-specific profiles.

Google Analytics is a web analytics service provided by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. Google Analytics uses “cookies”, which are text files placed on your computer, to help the website analyse how users use the site. The information generated by the cookies about your use of the website will generally be transmitted to and stored by Google on a server in the United States. Where IP anonymisation is activated on this website, within the member states of the European Union or in other countries which are signatories to the European Economic Area Agreement, your IP address will be abbreviated beforehand. Only in exceptional cases will the full IP address be transmitted to a Google server in the USA and abbreviated there. Google will use this information on behalf of the operator of this website for the purpose of evaluating your use of the website, compiling reports on website activity and providing other services relating to website activity and internet usage to the website operator. Your IP address transmitted from your browser in connection with Google Analytics will not be associated with any other data held by Google.

Google is certified under the terms of the EU-US Privacy Shield thereby undertaking to comply with European privacy laws. Further information on this subject is available here: https://www.privacyshield.gov/EU-US-Framework.

Disabling access by Google Analytics

You may prevent the placement of cookies by adjusting your browser settings.

You can further prevent the collection by Google of data related to your use of the website (incl. your IP address) by the cookie and the processing of those data by downloading and installing the browser plugin available here: https://tools.google.com/dlpage/gaoptout?hl=de.

We would advise you that if you prevent the use of Google Analytics, you may not be able to use all of the website’s functions to their full extent.

12. Use of Google Tag Manager

We use Google Tag Manager. This allows us to manage website tags via an interface. This service solely implements tags, so no personal data are collected. In addition, Google Tag Manager does not use cookies.

More information about Google Tag Manager is available here: https://www.google.com/intl/de/tagmanager/.

13. Online presence on Facebook

We have an online presence on the social network Facebook, in order to communicate with interested users and to inform them about our company.

Facebook provides us, as the page operator, with what are known as “Facebook Insights”. When you visit our page, cookies are placed which collect anonymised statistical data. The cookies are placed by Facebook and are a mandatory requirement for our use of Facebook.

Data subject rights may be asserted against us or Facebook. We would however point out that it is most effective to make such claims against Facebook because only Facebook has access to the processed data and can take corresponding measures and provide information.

16. Disclosure of data to third parties

The personal data provided by the data subject are used exclusively for internal purposes by the data controller and collected and stored for the data controller’s own purposes. Within our company those in-house departments and/or organisational units receive such of your personal data as are necessary for them to fulfil our contractual and statutory obligations or within the scope of processing and pursuing our legitimate interest. As the data controller, we may use subcontractors in order to provide and execute our services or we may permit the sharing of your data with one or more contract data processors who, equally, will use the personal data only for internal purposes which may be attributed to the data controller, e.g. in connection with handling a contract, for the purpose of complying with statutory obligations which require us to provide information about, report or share data, or where the disclosure of such data is in the public interest; insofar as external service providers process data at our behest in the role of contract processor or parties assuming certain functions (e.g. external data centres, support/maintenance of EDP/IT applications, archiving, data destruction, purchasing/procurement, customer management, letter shops, website management, auditing services, credit institutions, printers or data disposal businesses, courier services, logistics); on the basis of our legitimate interest or the legitimate interest of a third party (e.g. authorities, information agencies, debt collection agencies, solicitors, courts of law, assessors, Group-affiliated companies and supervisory authorities).

17. Facebook Custom Audiences

We use Facebook Custom Audiences, a service provided by Facebook Inc., 1 Hacker Way, Menlo Park, CA 94025, USA, and/or if you are based in the EU, Facebook Ireland Ltd., 4 Grand Canal Square, Grand Canal Harbour, Dublin 2, Ireland. Facebook Custom Audiences uses what is known as a Facebook pixel. With the Facebook pixel, Facebook can designate visitors to our website as part of a target group for advertisements. We therefore use this to show our Facebook ads only to those Facebook users who have also demonstrated an interest in our website or who display certain characteristics that we share with Facebook (so-called “Custom Audiences”).

When you visit our websites, the Facebook pixel is integrated into Facebook and a cookie may be stored on your end device. When you visit our website after you have logged in or while you are logged in to Facebook, your visit to our website will be noted in your profile. These processed data are anonymous to us but are used by Facebook for its own market research and advertising purposes.

More details about Facebook ads are available in Facebook’s privacy policy:

More information about the Facebook pixel is available here:

You can opt-out of being logged by the Facebook pixel and the use of your data for the purpose of being shown Facebook ads; see settings for usage-based advertising:

18. Legal obligation to process data

Like anyone involved in business activities, we too are subject to many legal obligations. In the first instance, these are statutory requirements (e.g. commercial and fiscal laws) as well as possibly supervisory or other obligations imposed by official authorities. The purposes of processing may include the fulfilment of supervisory and reporting requirements under fiscal law, the archiving of data for data protection and data security purposes, and auditing by fiscal and other authorities. The disclosure of personal data may furthermore be necessary as part of measures imposed by the authorities/courts of law for the purposes of gathering evidence, prosecution or the enforcement of civil claims.

19. Data security

In order to prevent unauthorised access or disclosure, to guarantee the correctness of data, and to ensure the authorised use of data, we have implemented technical and organisational measures to secure and protect the data that we obtain online, as set out in Art. 32 GDPR. We secure our website and other systems against manipulation, loss, destruction, access to, alteration or dissemination of your data by unauthorised individuals.

20. Erasure and blocking of personal data

We erase or block the personal data we have collected pursuant to Arts. 17 and 18 GDPR.

We store and process personal data only for as long as this is necessary to achieve the purpose for which the data were stored. Data may also be stored for longer than this where such retention is foreseen by European and national lawmakers under EU regulations, laws or other provisions to which we are subject. In this case, the data are blocked for other uses.

As soon as the purpose for which the data were stored has been fulfilled or the retention period set out by the mentioned provisions has lapsed, the personal data are routinely blocked or erased.

21. Questions and notes

When you use our website, the version of the Privacy Policy that may be retrieved online at the time of your visit shall apply. We reserve the right to amend or update this Privacy Policy as part of the further development of the website or because of statutory or official requirements.

We would ask our users to inform themselves regularly about the content of our Privacy Policy.

If you have any other questions about privacy relating to our website, you can contact us at the e-mail address shown above. We will then try to answer your questions and clear up any concerns you may have.
