Elon Musk's former right-hand man at X will give you 30 minutes of business advice for $15,000

Nikita Bier, X's former head of product, is charging $15,000 for 30 minutes of business advice on Intro.

Linnea Bullion for The Washington Post via Getty Images Nikita Bier offers $15,000 Intro sessions to venture-backed companies seeking advice.

Bier's sessions cost $500 per minute, with a minimum booking of 30 minutes available.

Intro lists Bier as its second-most-expensive expert, behind Hudson Leogrande's $20,000 session.

It's hard to put a price on good advice, but Nikita Bier can: $15,000.

Bier, who stepped down as X's head of product earlier in August after a little more than a year in the role, is selling one-on-one video consultations through Intro, a marketplace for expert advice.

Intro advertises Bier's sessions as “starting at $7,500,” and his profile describes a 15-minute call.

However, the only listed purchase options start at 30-minute sessions for $15,000.

These prices put Bier's time at $500 per minute, or $30,000 per hour.

His sessions are not for your average Joe.

The listing says he will accept bookings only from venture-backed companies.

During the call, Intro suggests that customers can ask at least three questions about startups , growth, or investing.

Bier says he can advise on viral growth, product development, design, community building, fundraising, and growing a social following.

Suggested questions include: "How would you launch my app?" and "What are the best distribution channels for growing my app?" Bier's Intro page highlights his prior startup experience for potential paying customers.
