San Francisco

As hot startups prepare for multibillion-dollar public offerings, their soon-to-be-enriched employees are being inundated by high-end sales pitches.

Thick books offering luxury yacht rentals, which can cost a quarter of a million dollars for a week in the Mediterranean, have landed on the desks of executives at Pinterest and Airbnb Inc. Private jet companies have tempted early employees at tech startups with unsolicited email pitches. Some tech workers say they have been wined and dined by wealth managers at Morgan Stanley and JPMorgan Chase & Co., who dangle the benefits of parking IPO fortunes with them.

So it goes in Silicon Valley, where there are plenty of luxury services ready to help tech workers spend their newfound wealth. Friday’s strong public-market debut of ride-hailing company Lyft Inc., now valued at roughly $30 billion, is expected to kick off a rush of massive IPOs that include competitor Uber and digital-imaging company Pinterest, supplying the Bay Area with possibly thousands of new millionaires.

The windfall is highly anticipated at Pinterest, which has only allowed employees to sell a limited quantity of shares on the market during the startup’s eight-year history. In comparison, Uber has held two tenders in which early employees have already cashed out billions of dollars.
