DLA Piper and Winston & Strawn are advising on e-commerce site Groupon's initial public offering (IPO), reports The Am Law Daily.

The website, popular with customers for its deal-of-the-day discounts, filed for the eagerly anticipated IPO on Thursday (3 June), and is hoping to raise up to $750m (£460m).

Steven Gavin, the chairman of Winston & Strawn's corporate department, is advising Groupon, along with corporate partner Matthew Bergmann.

The firm that has handled the bulk of Groupon's litigation work is DLA Piper. DLA is representing the underwriters the IPO, which include Credit Suisse, Goldman Sachs and Morgan Stanley.

Peter Astiz, global co-head of the technology group at DLA in East Palo Alto, is leading a team from the firm that includes corporate securities partners Gregory Gallo and Jason Harmon.

DLA also handles corporate work for Groupon, having advised the company on its acquisition of German startup Citydeal last year.

Groupon, which was founded in November 2008, had $1.3bn (£800m) in sales for the year ending 31 March and first quarter revenue this year of $645m (£396m), according to a filing with the SEC. Groupon has lost $522m (£320m) since its founding.

The news comes alongside four recent partner hires for DLA Piper's US operations.

The firm has recruited two practice group leaders from White & Case in New York – former global tax planning committee chair Gerald Rokoff and former investment funds co-head David Goldstein – as well as ex-Pillsbury Winthrop Shaw Pittman IP and technology partners Claudia Wilson Frost and Jeffrey Johnson in Houston.
