SAN FRANCISCO — Pinterest on Wednesday priced its shares at $19 each for its initial public offering, in a sign of healthy demand by investors after the appetite for fast-growing but money-losing tech companies appeared to be on the wane.

The price valued the digital pin board company, which lets people save images and links from around the web, at $12.7 billion. That is a little above its last private fund-raising round, which had pegged the company at $12 billion.

By selling at $19 a share, Pinterest raised $1.6 billion from big investors in the offering. The shares will begin trading Thursday on the New York Stock Exchange under the ticker symbol PINS.

Pinterest’s pricing could bode well for the many “unicorns” — start-ups worth more than $1 billion — that are rushing to the public markets. It follows a rocky debut for the ride-hail company Lyft, which went public on March 28.
