Groth and Jennison, 21, said they came up with Tab for a Cause after thinking about ways that charities could better connect with people by using the Internet.
"Thinking about this we realized that new tab pages are pretty much blank real estate for us to capitalize on and allow charities to reach people," said Jennison, who graduated from Grinnell College this year.
Since launching last August, Tab for a Cause has gained 3,000 users and donated about $4,000 dollars.
