Eryon Digital builds custom software, AI agents and automation for businesses. We bring work scattered across notebooks, spreadsheets and group chats into one system. AI handles the repetitive part, and the decisions stay with you.

We do three things well.
Behind every service is a product that runs today. We tried each one on our own work first.
Custom business software
A web dashboard and phone app written around how your business runs. Customers, work orders, field crews, collections and invoices sit in one place, and your team works from the field on their phones.
Agents that read and sort the work you repeat every day, such as email, documents, quotes and reports, and bring it to you as a decision ready to make. They learn from your choices and ask you when they are unsure.
From a raw recording to a publish-ready package, from a single visual to a thirty-day posting calendar, we build your brand's content pipeline end to end. Your team creates, and the system carries the rest.
Agents do the work, you have the final say. Pick a problem and see how we work.

We built them for ourselves first.
Everything below runs today. The screenshots come from the real product, filled with sample data.
A product for elevator maintenance companies
Bak&Ar
End-to-end operations software for elevator maintenance companies. Customers, buildings, contracts, monthly maintenance, breakdowns, inspections, collections and e-invoicing in one dashboard. Technicians fill in maintenance forms on their phones, attach photos and open an elevator's record with a QR code.
An agent that reads three inboxes four times a day, tags every email and sends it to your phone as a card with buttons. It learns as you tap. After ten identical decisions for the same sender, it turns them into a rule of its own.

The production line that runs our own YouTube and Instagram channels. From a raw recording it produces the cut list, chapters, title, description and cover drafts, then publishes the prepared posts on schedule. A person always gives the final approval.

Running on our own channels
A studio that comes from the work itself.
We know the shop floor
Our founder has run a manufacturing workshop for eleven years. We think about software from inside a business where the phone never stops ringing.
Fast, with an AI team
AI agents write the code, the tests and the reviews together, and a person signs off every critical step. That is how a small studio delivers the work of a large team.
Nothing ships untested
Bak&Ar is guarded by more than 4,800 automated tests. Sensitive areas such as money, permissions and data deletion get an extra review.
The system is yours
When we build custom software for you, the code, data and accounts are set up in your name. If we ever part ways, your system keeps running.
Good software makes the day shorter for the person doing the work. That is why I started Eryon.
OEOğuzhan Eryılmaz, Founder
Four steps. Each one moves on with your approval.
1
Discovery
We study your work together and find where time is lost and where information goes missing. At the end we tell you plainly what is worth turning into software.
Output: A written discovery report
2
Prototype
We prepare a clickable first version filled with examples that look like your data. You hold the screens in your hands and catch gaps early.
Output: A clickable first version
3
Build
We build a launch-ready system guarded by tests. Every significant change starts from a point you can roll back to.
Output: A tested, launch-ready system
4
Launch and care
We go live together and keep watching the system afterwards. As your business changes, your software changes with it.
Output: A monitored, maintained system
We never move to the next step until the current one is done and you approve it.
Is part of your business running on spreadsheets?
Tell us about it and we will look at it together. The first call is free and takes 30 minutes: we listen to how you work and tell you plainly what can be automated.
