Receive site output as it comes.
Every answer is captured as structured data and connected to the site, investigator, country and study it came from.
Compare patient access, recruitment expectations, study interest, operational capacity and protocol concerns as the responses arrive. No manual consolidation. No waiting for the final spreadsheet.

Primary Constraints to Site Performance
Operational factor most likely to restrict enrollment or study execution
“It’s not even about the immediate time saving. Yendou generates credible data about startup timelines and recruitment metrics and puts it next to our historical data. This saves us hundreds of hours down the track, headaches and arguments with clients. Having a higher level of certainty that you’re selecting the right sites, and being able to show clients where that confidence comes from, has massive downstream time, cost and headache savings for us.”
Head of Study Start-UpMid-cap CRO
The first platform sites don’t resent.
No portal. No login. No question they’ve already answered.
“My experience? Well, it was really easy. I was able to click, click, click and see everything. It’s very nice. It’s very clean. It’s got a very nice overview. I really like it.”
Annette ZauchaElligo Clinical Research
“It’s great working with you guys. You’re offering site networks a level of control and comfort we never experienced before. We’re being notified when there’s opportunities, and not worrying about our sites falling off a list. They won’t be forgotten.”

Questions
Before you send us a study.
- How much setup is there?
- About an hour. Select the sites or upload your list, create the form from the library or your own template, prepare the email and set the cadence. Then activate.
- Do sites need a Yendou login?
- No. Sites receive an email with a link to the form and answer from their inbox. Nothing to install, no account to open.
- What happens to the answers?
- Every response is captured as structured data, connected to the site, investigator, country and study it came from, and kept on the site’s record for the next feasibility.
- Who owns the data?
- You do. Your feasibility history, delivery evidence and site relationships stay in your workspace. Nothing you put in trains a model anyone else can touch.
