Based on affiliation of Directors I wouldn't be surprised if it was Acacia Capital behind the scenes on financing.
"Acacia Capital Partners is no longer investing. It is a venture capital firm specializing in direct and secondary investments in late stage companies. It prefers to invest in the technology sector. For its direct investments, the firm seeks to invest between $5 million and $8 million for ownership between 10% and 15% in its portfolio companies. It prefers to exit its investments in two to three years. The firm seeks to invest in companies with strong intellectual property. For its secondary/indirect investments, it makes expansion capital and early stage investments. The firm also invests in acquisition of venture capital portfolios."
