As a veteran Silicon Valley investor on the faculty of Stanford business school, Andy Rachleff spends much of his time counseling young tech workers on how to manage their money and careers. His company, Wealthfront, offers software-driven money management, as well as tools for mulling your best next move as you consider the arc of your tech career.

Into this mix, Rachleff has just added a note of heresy. In a recent blog post, Rachleff says he tells students eager to jump into the glamorized world of tech startups to just say no. To build the best career, he says you should go to work for an up-and-coming midsize company that’s growing fast and has momentum to spare.

“You get more credit than you deserve for being part of a successful company, and less credit than you deserve for being part of an unsuccessful company,” Rachleff says. And since most startups fail, he says, the risk-reward calculation doesn’t add up. Investing in your career is just like investing in companies, he says: “You want the highest possible return for the least amount of risk.”

Some of the top 10 include Jawbone (photo), Dropbox, New Relic and Sugar Inc. to name a few.
