Ever heard of / used these guys

Seems like these guys should be coming to GOSH events or active in the forum at least:

Anyone know them or have seen / used their work? I’m amazed at the price of the Spectruino 3 - I’m sure it’s using the same hamamatsu mini spec that we are considering for the single pixel camera, but it’s under 500 bucks… that’s pretty darn cheap compared just to their manufacturing costs.
