Boston Tech Roundup: DataXu, Imprivata, Flashnotes

A few financing deals that percolated up around the Boston area this week:

—Boston-based advertising software company DataXu has raised another $10 million and added a new board member. The new cash was revealed in an SEC filing this week, and the company confirmed to the Boston Business Journal that the money came from existing investors. That puts DataXu at about $75 million raised in its lifetime. New board member Dan Demmer, previously president of Endeca, will be the chairman of the company’s audit committee. CEO Mike Baker has previously said DataXu plans to take itself public in the future.

Imprivata, a Lexington, MA-based maker of healthcare software, says it has confidentially filed paperwork for an IPO. The company’s announcement is part of the newer wave of IPO filings under the federal JOBS Act, which lets companies of less than $1 billion in revenue file their draft registrations secretly. Imprivata’s investors include Polaris Partners, Highland Capital Partners, General Catalyst, and SAP Ventures.

Flashnotes, a Boston-based company that lets students buy and sell study materials, has raised a $3.6 million Series A investment. This follows the company’s SEC filing noting a new fundraise last month. The round was led by Stage 1 Ventures, and also featured investments from Runa Capital, Soft Bank Capital, and Atlas Venture. The startup raised a $1.8 million seed round in 2012 and added another $1.5 million last year, as it acquired a competitor.
