Random idea:

Take the applications of these companies through zaps.

So they have to zap a fix amount to book a timeslot.

Would it make sense to spend 5 minutes on such for a good amount of sats?

Would be interesting to see if they would pay sats to do these discussions that will end badly for them.

I would go with the elevator pitch model, giving 5 minutes for them, and they have to pay for their slots.
