Nanigans, a Boston-based Facebook ad software firm, may not be sending its employees westward, as rumored. But the company is losing its senior VP of marketing, Dan Slagen, to a local upstart.

HourlyNerd, which offers an online marketplace linking MBAs with businesses for part-time or freelance work, today announced that it has hired Slagen as its chief marketing officer.
