How it works
From listing to site selection
in days — not weeks
The entire site selection process — CDA, feasibility questionnaires, bidding, and shortlisting — on one compliant platform.
1

Sponsor posts a listing

CRO or sponsor publishes non-confidential trial details — indication, phase, sites needed, patient criteria, and deadline. No protocol shared yet.

2

Sites discover and bid

Investigators browse listings matched to their specialty and submit an Expression of Interest — patient cohort data, trial experience, and site capability.

3

CDA signed digitally

Shortlisted sites sign a digital CDA. Protocol details are unlocked. 21 CFR Part 11 compliant e-signature with full audit trail — no paper.

4

FQ → Site selected

Sites complete Basic FQ and Protocol FQ online. Sponsor scores, shortlists, and generates a sponsor-ready PDF report. Sites confirmed.
