Teespring announced the close of $5 million in financing from an undisclosed investor.

Leading social commerce platform Teespring is expanding its executive leadership team, bringing on Douglas Myers as Vice President, Global Operations.

Teespring itself is changing. It is no longer an unknown platform, a Wild West with limitless opportunity for the right entrepreneur. More than 4 million people in the US bought things from Teespring last year. It has expanded beyond T-shirts into other kinds of clothes. In late September, Teespring began an expansion into Europe, and in August it struck a licensing deal with the NFL.

Teespring, a San Francisco-based startup, lets people create custom t-shirt designs and then sell them online without having to worry about inventory. Its sales pitch is that it helps fuel entrepreneurship around the world.

The NFL and startup Teespring announced a partnership on Wednesday to allow licensed apparel to be sold on the startup’s website, connecting America’s most popular sports league to a marketplace that sells millions of user-created products. The deal could pave the way to much more personalized apparel with NFL licensed images, and a path to enormous scale for the high-growth startup.

Online payment services company Payoneer and e-commerce company Teespringare partnering to expand payment options in emerging markets.

Leading social commerce platform Teespring today announced it has partnered with music merchandise company Manhead Merchandising to deliver custom apparel for its portfolio of music artists. This partnership, an industry first, enables Manhead Merchandising to leverage Teespring's innovative platform to expand its ecommerce business.

Teespring, one of the top T-shirt sellers in the U.S., printed more than 7 million shirts last year. Hundreds of people like Hsu and Springer made more than $100,000 in 2014 selling tees through the company’s site; 20 collected more than $1 million, according to Chief Executive Officer Walker Williams.

Fast-growing custom apparel startup Teespring, which is backed by nearly $57 million from Andreesen Horowitz, Khosla Ventures and others, is making a move to expand its footprint globally through the strategic acquisition of European apparel platform Fabrily. 

Teespring, the two-year-old custom apparel startup announced Tues. it’s raised $35 million in a Series B round led by Khosla Ventures, with partner Keith Rabois joining the board. Earlier investors and board members include Lars Dalgaard of Andreessen Horowitz and Sam Altman of Y Combinator.

Teespring, a manufacturer of custom T-shirts used for fundraising campaigns, plans to open a new facility in Hebron, creating nearly 300 new jobs and invest nearly $22 million into the project. 

Teespring, a FundersClub and Y Combinator-backed startup that allows anyone to outsource the production and distribution costs involved with selling their own custom T-shirts, has raised $20 million in new funding in a round entirely led by Andreessen Horowitz. 

Last year at Brown University, Walker Williams and Evan Stites-Clayton created Teespring, a crowdfunding Web site that sold custom-made apparel — “Kickstarter for T-shirts.” For six months they had mild success with fraternities and campus clubs but were only slightly profitable.

But a startup called Teespring is generating a huge buzz at Y Combinator’s demo day. The company presented today to a roomful of investors and press, and announced that it pulled in $750,000 in revenues in a single month.

Y Combinator startup Teespring is growing revenues a massive 50% month-over-month while selling custom T-shirts for clients as diverse as Node.js, Hacker News, and a memorial for three air ambulance crew members who lost their lives in the line of duty last year. The startup is still in the YC 2013 winter class and has already hit $750,000 in monthly revenue.

To say Teespring is a hit with the team is an understatement. It addresses every issue an upstart apparel brand has.

At first glance, Teespring looks like it’s trying to become a Kickstarter for t-shirts, with its recently launched website that allows anyone to design custom tees which are then crowdfunded into production. But as co-founder Walker Williams explains, the two business models are not quite the same.
