One of Toronto's best-regarded digital design firms has shut down after its top talent was hired by Facebook. Teehan+Lax, the company responsible for the design of Medium, among other marquee projects, will be winding down current projects and closing down their Toronto offices in the wake of the talent-acquisition deal, which will see founders Jon Lax and Geoff Teehan and partner Dave Gillis moving to the Bay Area.

According to a post on the firm's site, the company began to entertain the possibility of an acquisition after the challenges of growing the firm began to conflict with the partners' desire to work on new projects and solve large-scale problems.

"The challenges that we will have at Facebook are challenges that interest us," the partners wrote. "They are primarily about making things that over a billion people will use ...all over the world. The opportunity to work on interesting and meaningful problems at such scale is very compelling."

According to TechCrunch, the deal will result in the loss of about 40 jobs.
