District-based EverFi added to its portfolio of software products last week with the launch of Haven, a program designed to teach college students about sexual assault prevention.

EverFi expanded its footprint within the college market in March when the company bought Outside the Classroom, the firm behind a Web tutorial on substance abuse that’s widely used on college campuses.

The education company, which got its start developing financial literacy software for high schools, said Haven will launch on 80 campuses in the coming academic year.

“Our goal is to help institutions and their students take positive steps to combat sexual violence — to create a culture where it is prevented and absolutely unacceptable,” chief executive Tom Davidson said in a statement.

Blackboard speculation

Shares at District-based Blackboard leapt on Friday following a Wall Street Journal report that the education firm was in exclusive buyout talks with Providence Equity Partners.

The firm said in April that it had received multiple, unsolicited offers from prospective suitors and that it retained Barclays Capital to help weigh its options. The Journal’s report said a decision could be reached next week, though the company declined to comment.

Several analysts said when the talks first began that a private-equity buyer would make sense for Blackboard because its stock at the time had been trading below what some industry observers thought it was truly worth.

If the news proves true, it would be the second big local buy for Providence in as many months. The firm paid $1.9 billion for Fairfax-based SRA International earlier this year.

Decision at DDOT

Arlington-based Decision Lens won a contract last week from the District’s Department of Transportation to help the agency juggle the competing demands of foot and bike traffic with an automobile and mass transit network.

Brothers Daniel and John Saaty created the firm’s software using a mathematical algorithm developed by their father called the Analytic Hierarchy Process. It helps decision makers to make tough calls by assigning a numerical value to different factors that impact the decision.

The company did not disclose the terms of the contract.
