Client Testimonials:

How They Experience Our Collaboration

David Charreyron | Administrative director - A/tout THÉÂTRE

Congratulations on the site and the effort you’ve put in. All of the actors we deal with are blown away by the result, and I’ve already received feedback from a client who was concerned that the rates would rise due to our progress on the site, so I’m thrilled and grateful to have come through you. An actual increase in client requests resulted from fine-tuned optimization, as well as feedback from former customers who were unaffected by the change but saw our offer scale up. Our only regret is that we did not contact All-In Factory sooner.

Marco Tribuiani | Account Manager - Netino By Webhelp

All-in Factory is a serious agency that goes beyond expectations, proving to be strong in proposals and very relevant in each intervention. During our collaboration, they perfectly mastered the subjects related to SEO and Social Media Management. The multicultural team is particularly advantageous: it can provide the same quality of work in several languages.

Eduard Schamber | CEO & Founder - Filmustry

We did a rebranding for my company together and this needed a whole new Design, Website and Identity. The Team of All-In Factory has really creative ideas, a great feeling for design and lots off technical skills regarding analysis and SEO. I had a tight schedule to get a dynamic, modern and effective website for my new brand ready, to connect with new customers on an important german fair. All-In Factory was very ambitious to hit that goal in time… and they did! Thank you very much.

Paul Emmanuel Renault | Founder & CEO - Esprit Calme

Excellent communication (it’s more important than one might think). Good listening skills to understand the situation. Tailored proposals and execution as promised for a reasonable fee. AllInFactory is a serious company with dedicated professional participants. Three things were important to me: professionalism, engagement, human business relationship, execution, and price… deal concluded.

Pawel Skalski | Social Media Manager - Desigual

The strengths of the CM team at All-In Factory lie in their capacity for managing communities in multiple languages, as well as in their clear and effective communication, originality, and impeccable spelling…

Alex Braunagel | Managing Partner - Cosynex

  • Generally, the app development process can take anywhere between 3 to 9 months. However, this timeline can vary based on the complexity of the app and the specific needs of your project. At All-In Factory, we prioritise clear communication and efficiency to ensure your app is ready for launch as soon as possible.

  • The budget for app development can significantly vary based on the features, complexity, and platform. On average, you can expect to budget anywhere from 10,000€ for a simple app to over 100,000€ for a more complex app with multiple features. All-In Factory offers a free consultation to provide a rough estimate of costs for your specific app project.

  • Freelancers may be fitting for minor projects with fewer complexities, but managing them becomes intricate as you’ll need to handle coordination, testing, and project management independently.
    Agencies like All-In Factory, however, offer a full range of expertise under one roof, relieving you of the management burden. Our team, ranging from app developers to project managers, collaboratively work towards your project’s success. We don’t just execute but also provide strategic advice based on our industry experience. As your partner, we deliver regular project updates and handle all internal coordination and testing, thereby offering a more streamlined and efficient development process.

  • A user-friendly app is built on a deep understanding of its target audience. This involves designing engaging, intuitive user interfaces, defining clear use cases, and thoroughly testing the app for usability. At All-In Factory, we specialise in user-centric design and development to create apps that resonate with your audience.

  • Understanding your user’s needs and delivering value are key to creating a loved app. We use user research, persona creation, and UX/UI best practices to ensure we develop an app that resonates with your target audience.

  • Starting app development requires a clear concept, including your app’s purpose, target audience, and problem it solves. Specifications on design and functionality are beneficial. These details should be organised in a requirements document, which All-In Factory can help you formulate. Our team will review and use this as the foundation for the development, ensuring all phases align with your vision and goals.

  • Ensuring the quality and performance of your app is of paramount importance. At All-In Factory, we adhere to rigorous testing procedures and quality control measures to ensure your app is high-performing and bug-free. Our agile development methodology allows us to spot and fix issues early in the process, ensuring a superior final product.

  • Data security and privacy are at the forefront of our app development process at All-In Factory. We adhere to global data protection standards and employ the best security practices to ensure your app is secure and your user’s data is protected.
