For manufacturing, logistics and sales
BitFun, based in Osaka, builds web systems and mobile apps around the way your manufacturing, logistics, or sales work is done, and takes them from planning through to operation. We start small and grow the system with you as the results come in.
In factories, warehouses, and sales offices, information tends to end up split across paper, Excel, and separate systems. We map the workflow with you and turn it into a system your frontline staff can use every day.

The same team builds the web admin screens used in the office and the smartphone and tablet apps used on site, so the office and the front line see the same information.
Offshore development lets us keep quality up while holding down cost and lead time. We propose a team setup that fits the size and budget of your project.
We start from the business challenges in manufacturing, logistics, and sales, then propose and build what fits them, centered on web systems and apps.
Web systems for core operations in manufacturing, logistics, and sales, such as production control, inventory, ordering, delivery, and sales management. We also connect them to your existing systems and automate reports and data aggregation.
iOS and Android apps for factories, warehouses, delivery routes, and stores, covering tasks such as barcode scanning and work logs. We design them so frontline staff can use them without having to stop and think.
We help you put AI to work on your business data, for example in demand forecasting, image inspection, document reading, and answering inquiries. We build it into your existing systems to cut the manual work on site.
From planning to delivery, we stay in close contact with you. We share progress at each stage and report often, so you can leave the work with us with peace of mind.
We listen carefully to your challenges and requirements, then propose how to meet them.
We show you screens and working features early, and design and build with your feedback along the way.
We test the system thoroughly before we deliver it.
We keep the system running smoothly and continue to propose improvements.
Products we have developed.
The era of drawing every detail of 2D assembly and part drawings just to get a design checked will soon be over. GenDora is an app that outputs your 3D CAD data as a single file that opens in a web browser (HTML format).
Opens in a web browser
Just open it in a web browser: the recipient needs no CAD software, no installation and no internet connection.
The assembly in 3D
Turn the whole assembly in 3D and check its shape and structure without reading 2D views.
Drawings in the same file
Drawing PDFs linked to parts open in the same file and can be annotated.
AR without an app
On iPhone and iPad, open the file in Microsoft Edge and view the model in AR, no app needed.
From the data you have
Output straight from STEP, IGES, OBJ, IFC and other 3D CAD data.
It runs on a render engine we developed in-house. For companies, we can also discuss custom builds linked to project management, starting with a proof of concept (PoC) if you prefer.

At BitFun, our mission is to realize your vision through technology. We owe our journey to the support of our clients. First and foremost, we sincerely thank everyone for their continued patronage.
In recent years, the remarkable evolution of AI technology has rapidly flattened the world, and the IT industry is changing at an unprecedented pace. While advanced technologies are now easily accessible, the commoditization of technology has intensified corporate competition. In such an era, what we value most is the fusion of “technology” and “passion.” No matter how advanced the technology, it is human intent and creativity that bring it to life. We combine meticulous technology with passionate creativity to deliver practical and effective IT solutions. From optimizing business processes and reducing costs to achieving business goals—each project we undertake is not just a service but a “promise” to help you overcome challenges and advance to the next stage.
The world of technology is constantly evolving and changing. At BitFun, we face these waves of change head-on, flexibly adapting where necessary while unwaveringly upholding our belief in prioritizing “what we can do for our clients.” We incorporate the latest technological trends, refine our processes, and pursue rapid and reliable solutions. In every project, we deliver transparency, integrity, and uncompromising quality.
Without our clients, we would not exist. That’s why we put our heart into creating solutions that support your growth and sustainable development. With technology as our foundation and passion as our driving force, we aspire to be your trusted partner for the long term.
We look forward to your continued support.
