The cryptocurrency company has been piloting an app that collects employees' evaluations of their colleagues, including their managers, after meetings and other interactions. Known as Dot Collector, the app was invented by Ray Dalio's hedge fund, Bridgewater Associates, and has been in use by Coinbase's HR and IT teams since the first quarter of this year. In the app, employees review how well their coworkers demonstrate 10 core values at Coinbase, including things like communication and "positive energy". They can share their input in the form of a thumbs up, thumbs down, or neutral review.
