Etsy Inc., the website founded a decade ago by a carpenter looking to sell wooden computers, is making its public debut as a $1.78 billion company. A marketplace for handmade and vintage goods, Etsy raised $267 million in its initial public offering, according to a person with knowledge of the matter. Brooklyn-based Etsy and some of its backers sold 16.7 million shares for $16 apiece, said the person, who asked not to be identified, after offering them for $14 to $16 each. The site's offerings include a knit coffee warmer for $6.50 and a 1960 metal typewriter for $85. Etsy makes revenue by charging sellers listing fees and commissions. As a public company Etsy's challenge will be to keep the artisans and craftmakers who sell their products on the site happy, as the it also seeks to build scale for investors.
