Yes – CTO of Amplify here.
As a sibling poster notes, the Desmos calculator and math tools spun out to Desmos Studio PBC, which has a bunch of great people – with the goal of ensuring those remain available to all and not tied to a single curriculum provider. The Desmos Classroom tools for social, interactive classroom instruction, and another bunch of great colleagues, are part of Amplify, which together with Polypad and other tooling, make up Amplify Classroom ( https://classroom.amplify.com ), powering terrific IMO math, science and English curricula.
It's been a lot of fun – and a lot of tricky work! – bringing all of these tools and humans together.
I'd be remiss if I didn't mention that we are hiring, including for Software Engineer, Analytics Engineer, Data Engineer, and AI Engineer positions at various levels :)
(Since you're in the thread, can I ask you to give kudos to whoever's kept the original "Let's Explore Geography! Canadian Commodities Trader Simulation Exercise" class code active all these years? I think you might have even changed the multiple-choice component to better support the weird thing I was doing with empty choice text.)
