Tired of the busywork?

We're architects building the design partner we always wanted

Sillmark takes the slow, manual parts of modelling and hands them to your tools, so you spend more time designing and less on upkeep. Built by architects who got tired of doing it all by hand.

Our story

Why Sillmark?

A sill is the line a building rests its openings on: a fixed reference that everything else is measured from. That is how our agent works. It keeps track of your model quietly, speaks up when something is off, and only acts once you approve.

Sillmark was started by architects who were spending too many evenings on modelling, cleanup and coordination. The tools were capable but passive: they waited for every instruction and offered nothing back. We wanted software that took the repetitive work off our desks without taking control away from us. So we built it.

Our mission:

  • Take the repetitive modelling off your desk
  • Catch problems while you design, not after
  • Make changes in your model, on your approval
  • Give back the hours lost to manual work

Our team

Built by architects, shaped by engineers

We are a mixed team with backgrounds in architecture, engineering, machine learning and BIM. What we share: the belief that software should do the dull work so people can get back to design.
