About Viaduct

Built because context kept disappearing.

Software architecture should not be a diagram someone remembers to update. It should be the shared, explorable memory of the system.

— Igor Golovko, Founder & CTO

01The reason

Why I started Viaduct

01

The diagrams existed. The context did not.

Our systems were documented across Miro boards and Confluence pages. They helped for a moment, then quietly fell behind. People stopped returning. The architecture was still there, but the shared understanding was not.

02

I started with one C4 diagram.

I wanted a way for my team to explain every service and interaction under our care—quickly, clearly, and without creating another document that would be forgotten. C4 gave the model a language. Interactivity made it useful.

03

The model became a place people came back to.

Once the diagram could open into flows, contracts, decisions and implementation context, it stopped being a snapshot. Knowledge stayed connected to the systems it described, and the context in people’s heads stopped disappearing.

The person behind the model

Igor Golovko

Founder & CTO of Viaduct

I build software and lead teams that have to understand complex systems together. Viaduct began as an internal answer to that problem—and became the tool I wanted us to have all along.
