Jack Altman is the second Altman brother to drop the CEO title in the last month — but this time, it's of his own accord.

Earlier this week, Lattice announced it was bringing on a new CEO — former Salesforce executive Sarah Joyce Franklin — and that Altman would step down from his role and become executive chairman, eight years after founding the human-resources software startup.
