Clarizen, provider of online work and project management software, has secured $8 million more in a Series C round of venture capital funding led by DAG Ventures, Benchmark Capital and Carmel Ventures. The total amount of venture capital invested in the company, which was founded in 2005, now totals $24 million.

The company provides collaborative project management software that allows businesses to easily manage all of their projects and resources in a single, online environment.

In 2009, Clarizen claims sales grew more than 400 percent year-over-year and that it has recruited more than 100 new customers in Q3 alone. The company says its products are now in use by over 500 customers.

The extra financing will be used to expand its marketing and sales operations.
