Independent research methodology

“For the form submissions, it doesn't do as advertised, so its a waste of money.”

Chris B.

Demand Ge

“Doesn’t provide a walkthrough on the dashboard”

Roshini A.

“I am unable to find any issues while using this tool.”

Arpit G.

Senior Analyst

Cons

“We found that Prospeo could only enrich less than 10% of the contacts we provided. Because they charge a minimum subscription fee per month, there would be months where we wouldn't meet this minimum due to their low success rates.”
