"There should be a repository where you've kept that information. Just ask me questions specific to this protocol. That's exactly what Yendou does — and it fills a real gap in the industry."

Tina Lightle

"You receive the survey pre-filled so you don't have to re-answer the same questions. That is very cool."

Victoria Alvarez

"Everything is awesome. Being able to reuse previous answers instead of typing everything again — and edit submissions if needed — makes this much better than anything else we use."

Jordan Tower
Velocity Clinical Research

"Yendou has been a favourite feasibility form submission. The ability to add multiple sites, save progress, and the user-friendly layout all contribute. It is much better than what we had before."

Brittney D.
KUR Research

"Much better than what we had before. The ability to go back and forth through different site feasibilities makes the whole process faster and cleaner."

Reanna M.
Rovia Clinical Research

"I can click through all the sections and see every question I'll need to discuss with the PI before I even start. That alone changes how we prepare."
