I don't need to tell anyone induction hobs aren't new, and in a few seconds' searching I found Miele and Fisher & Paykel (i.e. not cheap brands) 8kW hobs well under £1k, I'm sure I'd find 10+ kW if I bothered a little longer.
Seems like another example of 'what if we made a flashy website and a 'startup' out of something ordinary; pitching it as new, exciting, and high growth' to me.
