Mortgage data firm Actovia has struck a deal to buy its former competitor CrediFi, the Tel Aviv-based startup that abruptly shut down last month. New Jersey-based Actovia closed on its purchase Friday, company founder and CEO Jonathan Ingber told The Real Deal. Ingber founded Actovia in 2011 as a platform to provide access to commercial mortgage information on properties in New York City, and is expanding in the tri-state area.
