Same. Thus far, they mainly publish and sell risographie art but appear to be expanding into literature.
They have an Instagram with over 3500 followers @banzai.editions. They do appear on the 1st page of Google if you search the terms "editions Banzai" (it says "Acceuil ["Welcome"] - BANZAI Editions!"). The top 8 results features them.
Their website is here: https://www.banzai-editions.com/ and their FaceBook page is here: https://www.facebook.com/Banzai.editions/
Their website is in French but you can use a translate plug-in if you need another language.
One of their artists seems pretty popular, with over 25k followers on Instagram. They also have other artists with a fairly significant fan base and sell print publications on Amazon and their website.
ETA: Bonzai did not ask me for any money. But as a general rule, if you are approached by other publishers in the future, any publisher who asks you for payment is a fraud. Never, ever engage with a publisher who asks you for money. The publisher is responsible for absorbing any and all costs associated with your work (e.g. production, print, marketing/promo, translation, editing, etc.), this is the industry standard. And B.E. seem compliant with that.
If anyone receives emails from publishers asking for money, report them to Tapas Admin.
Have you asked for their draft contract to review? I did.
