Canadian e-commerce software maker Shopify Inc (SHOP.N) (SH.TO) said its U.S. initial public offering was priced at $17 per share, valuing the company at about $1.27 billion.

The company's IPO of 7.7 million class A subordinate shares raised about $131 million, after it was priced above the top end of the expected range of $14-$16. The offering was earlier expected to be priced at $12-$14.

The company sold all the shares in the offering.

"Pricing reflects big enthusiasm for these type of deals. It's a unique company in a hot area with lots of growth," said Josef Schuster, founder of IPO investment firm IPOX Schuster LLC. "There's going to be a big pop coming tomorrow."
