Cascade Angels announced Thursday an investment in call-center analytics software Topbox.

The sum of the investment, made by Cascade Angels Fund 2017 LLC, was not disclosed, but the Bend-based fund typically invests $100,000 to $250,000 per company.

Topbox, which has an office in Portland, says its software “reveals the source of friction points” in customer and buyer experiences.

Cascade Angels has invested in three other firms this year and will likely invest in one or two more before the end of 2017, spokeswoman Natalie Dent said. The Bend-based angel fund has invested a total of $2.5 million in 17 companies since 2014.
