Email and social account aggregator Threadsy has raised $3 million in Series B funding, according to an SEC filing.

Though the startup has yet to confirm the round or provide additional details, the filing lists the following persons involved in the deal: Simon Robert Goldman, CEO of Threadsy; John Johnston, co-founder of August Capital; and Amy Errett, partner at Maveron. Both Maveron and August, with participation from Harrison Metal Capital, previously contributed to Threadsy’s $3.3 million Series A round filed in 2008.

Threadsy aims to simplify online communications for the user by bringing together all the user’s accounts, including email--Gmail, Yahoo Mail, Hotmail, AOL Mail, Mobile Me, IMAP accounts--and social networks Facebook and Twitter, all under one roof.

The idea is that people want a service that lets them read all their messages in one place, with a focus on actual conversations with real people. Even for somebody who has their email accounts and social networks mentally organized, Threadsy’s interface is inviting purely because it manages to unify all those messages and updates.

Today’s new funding, when confirmed, will be the first news to come from Threadsy in awhile. The company blog was last updated nearly three months ago, though, to be fair, that update revealed a host of new upgrades to the service, including 30 minor enhancements and bug fixes. Major updates at the time were more intuitive streaming and scrolling options, constant fetching of new images, stats on shared links in the stream, and a faster chat interface.

Even the Threadsy Twitter account, which appeared to have been used for customer support, hasn’t let out a single tweet since mid-November.

Hopefully with this new funding secured, Threadsy can continue refining its service.
