The SoftBank Vision Fund has lost a newly promoted partner by the name of Carolina Brochado, who joined the Vision Fund from famed European venture capital firm Atomico. Brochado, who was promoted to partner just last month, has tendered her resignation from the SoftBank Vision Fund. She joined the fund early last year and helped back companies like Gympass, a Brazilian fitness startup, and Behavox, a company that develops compliance and employee-monitoring software.

Brochado was promoted to the partner position recently alongside another director at the SoftBank Vision Fund. She became one of the few women to occupy that position at the fund.

The motives surrounding her abrupt departure are unknown.
