What Sets Connect Apart?

Connect is built different from the ground up. Our proprietary participant pool is continuously vetted with behavioral screening, device fingerprinting, and AI-content detection — not just at sign-up, but on every study. Combined with built-in demographic targeting and census-matched sampling, Connect delivers data quality that legacy platforms simply can't match.

What Our
Researchers
Say

Connect has the highest data quality I've ever gotten! I'm not sure how you do it, but it's incredible.

Chase Herndon, Kansas State University

Social Psychology PhD Candidate

The Connect platform has been a game changer for me! The Teams feature saves quite a bit of work, I highly recommend it!

Jeff Galak, Carnegie Mellon University

Associate Professor of Marketing

This platform is great, it's super fast and almost everyone passes attention checks!

Dr. Grant E. Donnelly, Ohio State University

Department of Marketing & Logistics Sustainability Institute

I've used Connect quite a bit, and I've found it to be a very good platform! It's easy to use and the data are quite good when looking at open-ended responses and attention checks. I've also collected data that targeted Republicans and Democrats, and that worked well too! Thank you all for your work on this platform!

Crystal Hoyt, University of Richmond

Professor of Leadership Studies and Psychology and the Colonel Leo K. & Gaylee Thorsness Endowed Chair in Ethical Leadership

Connect combines best-in-class researcher tools with an outstanding panel of attentive and reliable survey respondents. The team's customer support is also exceptional. The new Teams feature makes it easy for collaborators on joint projects to field surveys without complicated workarounds or compromising the security of your accounts. I have integrated it into my workflow on all of my new projects on Connect.

Brendan Nyhan, Dartmouth College

Freedman Presidential Professor in the Department of Government

My experience with Connect has been phenomenal. They provided highly tailored and practical features in identifying, recruiting, and rewarding a specific group of participants for my longitudinal research project on suicidal ideation, helping me collect high-quality data while ensuring participants' privacy. I am confident that Connect is the best crowdsourcing platform for online research available on the market.

Hyungji Kim, Long Island University

PhD Candidate in Clinical Psychology

Connect is a great way to get attentive participants very quickly.

Ernest Baskin, St. Joseph's University

Associate Professor

CloudResearch helped me recruit a specialized and overlooked population to research the health needs of older sexual minority women who self-identify as having disabilities. The data I obtained was high-quality, with only four responses missing. I've recommended CloudResearch to other scholars as a result, and I look forward to using them again!

Jordan B. Westcott, The University of Tennessee, Knoxville

Assistant Professor in Counselor Education

I've used Connect since it first came around, and it has become my first stop for data collection. The interface is seamless, the pricing is fair, and the quality of participants is on par with—if not better than other online samples I use. The data get collected very quickly, and the team behind the website are very responsive and helpful. Five Stars all around!

Jacob Teeny, Northwestern University

Assistant Professor of Marketing

Connect has been so easy to use and has provided fast, reliable data within my budget. It made it easy to ensure my surveys weren't shown to the same participants — crucial for reducing bias.

Eva Bianco, Dartmouth College

Student Researcher

I am really satisfied with the quality of the results. People took their time to answer and weren't bots. Even a Master's student can afford to conduct a user study for publication.
