Chris Sacca’s seed investment firm Lowercase Capital has raised a $46.1 million fund, according to a filing with the Securities and Exchange Commission.

The Hermosa Beach firm’s prior seed funds were invested in companies such as Uber Technologies Inc., WordPress and Medium.

Lowercase Capital was founded by Chris Sacca, the former Google Head of Special Initiatives and a prominent angel investor. A frequent face on television news shows, Sacca is known for wearing cowboy shirts and naming Lowercase’s investment funds after western themes. This latest fund will be called Frontier, following funds named Stampede and Spur.

Sacca is also a frequent Twitter user and an early angel investor in the company. He publically criticized the company’s direction under former Chief Executive Dick Costolo and became instrumental in Costolo’s firing and the re-hiring of founder Jack Dorsey as chief executive last week.

Sacca became chairman of Lowercase in June. The firm’s investments are now led by Managing Director Matt Mazzeo, who previously worked in business development at Creative Artists Agency.

A Lowercase Capital representative could not be reached for comment.
