Beginning in 2017 with the discovery of GW170817 , we moved to the era of gravitational-wave multi-messenger astronomy. This single source, caused by the merging of two neutron stars, was detected both as a gravitational-wave source by the LIGO /Virgo interferometers, and as a multi-wavelength electromagnetic astrophysical transient. In this talk I will briefly recap ground-breaking results from GW170817 , and the scientific potential from observing more multi-messenger events, as motivation for the GOTO project. GOTO is an array of small, wide-field telescopes designed explicitly to enable multi-messenger and transient science. I will overview GOTO ’s performance thus far in various stages of development, and its contribution to gravitational-wave searches in the most recent LIGO /Virgo observing run. Now, in preparation for the next gravitational-wave observing run, O4, due at the end of this year, GOTO is transitioning to design specification and I will present the aims and prospects for GOTO in O4 and beyond, as a UK-led premier all-sky survey.
