Finding the first active supermassive black holes is one of the most exciting and yet challenging problems of extragalactic astronomy. These black holes are very rare, but they emit a considerable amount of light from their accretion disc and their very powerful radio jets. As such, they are amongst the brightest phenomena in the Universe. Finding them is of prime importance to understand their formation and evolution, but given their intrinsic rarity and distance, this becomes a needle-in-a-haystack problem. How can we most efficiently reveal those hidden monsters among the multitude of sources in the sky?
