Breakthrough Software was a software company based in Novato, California. Breakthrough developed and sold the Time Line project management software for PC DOS computers, releasing the first version in 1984, and version 2.0 in July, 1985. Company staff in the 1980s included president William Lohse (1984-1985), COO and CEO Victoria Lohse and president Andrew Layman starting in 1986.
The product was slightly renamed to Timeline by October, 1986.
Negotiations to merge Breakthrough into Integrated Software Systems Corp. (ISSCO) reached an agreement in principle in October, 1986 but broke down soon afterwards when Computer Associates, developer of a different project management program, announced an agreement to acquire ISSCO.
