It's becoming insane again in venture capital: A tiny AI startup wants investors to pay $100 to book a meeting with its founder.

• Dan Siroker, a founder of AI startup Rewind, is telling investors to pay up if they want to meet.
• He's charging $100 for bookings in an effort to conserve his most precious resource: time.
• It's a sign that the frothy AI startup market is edging into insanity.

The venture capital industry has mostly been a tale of woe in the past year, with thousands of startups struggling to raise money and many shutting down.

For some lucky founders, though, the market is as frothy as it's ever been, and edging into the realm of insanity again.
