The operating system built for mid-cap CROs to win enterprise bids. Every RFI, CDA, feasibility round, and CTA, captured once, structured forever. Ready the exact moment a sponsor's VP of Clinical Operations asks for the distribution.
Built by operators from ex-AstraZeneca, Parexel & Microsoft.
"Our expertise lived inside our heads and inside our email. The sponsor needed to see it as a distribution. We could not produce that."
Your expertise. Decades of operational evidence that should be winning the next bid. Today it lives in spreadsheets, inboxes, and people's heads. Yendou captures it once, structures it forever, and surfaces it the moment a sponsor asks.
Yendou is not a tool you adopt. It is a system that learns your team and gets sharper every study. Every RFI makes the next RFI cheaper. Every CDA, the next CDA faster. Every site reply, the next site survey shorter.
Pick the workflow that costs you most: RFI, Country & Site ID, Feasibility, or Contracting. Yendou agents run it to your playbook; you prove it on one bid, and every answer, site signal, and decision becomes Memory: organizational intelligence your CRO owns forever.

"My team moved from chasing functions for RFI answers and sites for feasibility and signatures, to authoring strategy, producing evidence, and building relationships."
"I'd never, in a million years, go back to spreadsheets and manual picking. That's crazy. The immediate impact has been on our sales cycle. We can now bid on over 2× more deals per quarter."
"Our expertise and insights on site performance was real. It lived inside our heads and inside our email. The sponsor needed to see it as a distribution. We could not produce that."
"Our growth strategy used to be constrained by our site network. It is now constrained by our operational judgement. That is the only constraint a CEO actually wants."
The site told you once. Yendou remembers forever.
No portal. No login. No question they've already answered.
Sites reply in 5 days because they aren't doing it twice.
“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.”
“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.”
Yendou is the engagement layer on top of your infrastructure, not a replacement for it. Feasibility responses, documents, and site details sync both ways with your CTMS and eTMF in real time, so your system of record stays current without anyone retyping. Already on DocuSign or Adobe Sign? Integration takes about two minutes.
"We finally have one place where CDAs, feasibility responses, and follow-ups happen, and our CTMS is actually up to date without anyone retyping."
Security architected for the world's most regulated workflows.
All your data stays in your environment. Yendou processes data in-transit with vector encryption, and your data is never used to train AI models. Every action is captured in immutable audit logs, governed by strict role-based access controls, and continuously monitored.
