Flux, the popular platform used by architects, engineers and construction workers to share models, markups and more, has announced that it will be shutting down on March 31 and transitioning to a new, as-of-yet unknown business model.

Flux was the first company to publicly spring out of Google’s Google X incubator in 2014, with a focus on making buildings more efficient, using AI to cut waste in the design process, and allowing users to easily share information. The company emerged with an $8 million valuation, which grew to $40 million this year.

In a statement released on BuiltWorlds, the company revealed that it would be targeting a “different subset of users in the marketplace,” and that Flux would be pivoting away from “end-to-end data sharing.” What this means for professionals using Flux in their projects is unknown, with their cloud-hosted tool suite going dark as they roll out a new platform for real estate professionals.

The new platform is scheduled for release in mid-2018. AN will update this post as we find out more information about Flux’s plans moving forward.
