Over the past decade, astronomy has transitioned into a new era of observation. We can now "listen" to the universe through gravitational waves, which are tiny ripples in space-time produced when massive objects like black holes or neutron stars collide. These signals tell us about some of the most extreme events in our universe, but they also raise new questions that light alone cannot answer.

To unlock their full potential, we combine gravitational-wave detections with electromagnetic follow-up observations from the same events. This approach, known as multi-messenger astronomy, allows us to probe everything from the origins of heavy elements to how fast the universe is expanding.

In this talk, I will introduce the Gravitational-wave Optical Transient Observer (GOTO), a robotic telescope network designed to rapidly respond when gravitational waves are detected. I will explain how GOTO searches the sky for the optical signatures that we expect to accompany the gravitational wave events, the strategies we use to maximise our discoveries, and the challenges of identifying the "true" counterpart amongst the false-positive imposters in the dynamic transient sky. Finally, I will highlight some of the exciting results from the current observing run and the opportunities that lie ahead.
