Independent research methodology

Our researchers use a mix of verified reviews, independent research, and objective methodologies to bring you selection and ranking information you can trust. While we may earn a referral fee when you visit a provider through our links or speak to an advisor, this has no influence on our research or methodology.

Verified user reviews

GetApp maintains a proprietary database of millions of in-depth, verified user reviews across thousands of products in hundreds of software categories. Our data scientists apply advanced modeling techniques to identify key insights about products based on those reviews. We may also share aggregated ratings and select excerpts from those reviews throughout our site.

Our human moderators verify that reviewers are real people and that reviews are authentic. They use leading tech to analyze text quality and to detect plagiarism and generative AI.

Pros

“The platform is user-friendly, both for our team and our bidders, and the online auction and mobile bidding features have noticeably increased our event revenue.”

Belinda V.

Chief Development Officer

“I love the simplicity of the mobile bidding site, the ability to pull reports a variety of different ways, and the ease of use for guests. And I truly appreciate everyone at the customer service center.”

Alicia S.

Development Assistant

“We had a little glitch during our event where images were not formatted correctly which covered some valuable information for our bidders.”

Ilana H.

Director of Fundraising and Special Events

Pros

“Event management capabilities were apparent and data reports that can be generated after an event are useful.”

Daniel C.

Benefits and Compliance Manager

“Volunteers pick up on the program quickly, sometimes day of an event and it all around lifts so much stress.”

Yemisi O.

Event Specialist

“There's a section for each feature I need, and there are lots of options if I need something specific for my event.”

Ashton N.

PR and Communications Coordinator

Cons

“It often takes 24+ hours to receive a response on a Help Desk ticket; seems it should be more immediate or offer a chat option.”

Dawn H.

Events and Communication Manager

“People did not like that they had to enter a phone number and email address just to look at the Silent Auction on One Cause.”

Heather O.

Events Coordinator

“Unfortunately it doesn't integrate into our CRM directly (Blackbaud/Raiser's Edge) but using Omatic is not a problem.”

Emily D.

Director of Philanthropy, Events and Partnerships

Cons

“In general, I like the system, but some things didn't go well for us (e.g., date of fundraiser event was incorrect, even though comms to GG about this were not acted upon, therefore credit card readers did not work - a disaster for check-in.).”

Rex B.

Treasurer

“It is just not very user-friendly changing some aspects of your published website, but otherwise there are not really any complaints.”

Rebecca C.

Administrative Assistant

“I would like to have the option to enter in an item number when adding items to packages, not just words. When you have multiple people getting packages ready, not everyone uses the same wording and it is putsy and annoying to have to go out of Packages and into Items to find what I'm looking for if I don't use the same words that someone else used to identify an item. If you are going to have us assign numbers, maximize that. ”

Carey H.

Fundraising Coordinator
