Waterloo, Ontario

Where serious
builders gather.

Waterloo produces serious builders. Founders, operators, engineers, designers, researchers, students. People who have shipped at companies you've heard of. People shipping their first thing.

They don't broadcast. They're just here working.

The talent was always here. The density wasn't. We fixed that.

They don't broadcast. The wins get out anyway.
