We built this because we are builders too.

We are a team of builders and vets in construction — architects, engineers, contractors, people who have been on site.

We have suffered all the pains in construction: drawings that don't line up, mismatched coordinate systems, wildly different bids, clashes only discovered after breaking ground.

23D is the tool we built for ourselves and our friends — solving our own problems first, then turning it into a product.
