Investics, which includes Intersouth as one of its investors, is expanding its management team.

The Atlanta-based software firm, which develops applications for lean manufacturing, closed on $5 million in B round venture capital earlier this year.

Lenny Purwin, who has more than 20 years of sales experience including stints at i2 Technologies and Eastman Kodak, takes over as vice president of sales.

Ed Lawton, who worked most recently at Optimum Profit Consulting, joins Invistics as vice president of presales consulting.
