Who it is forView

For simple studies, SaaS-only builds may be sufficient; for complex studies with multiple languages and proprietary instruments, managed services bridge the gap between visible software costs and hidden administration expenses.

Lead times and availabilityView

Setup timelines vary by complexity: simple EDC requires 3-4 weeks, medium 4-8 weeks, and high complexity 8-12 weeks from kickoff meeting to UAT. Managed eCOA studies follow the same timeline.

This is what is still missing.

Capacity2 questions

From a single piece to a large series: not every job suits every business. These questions make clear which quantities and project sizes you can take on.

Prices and quotes3 questionsThis question needs attention now

“What does something like this cost?” or “Can this be done within my budget?” Searchers often start with the price. Information about your rates and quotes helps AI put your offer in the right context.

Service area1 question

One person wants a business nearby, while another needs a specialist who is willing to travel further. Your answers make clear where, and on what terms, you help customers.

Certifications and labels2 questions

For some searchers a quality mark is a plus; for others a specific certification is a hard requirement. That’s why we map out which accreditations you hold and what they cover.

Sustainability1 question

One person looks for reused materials, another wants less waste or a product that lasts longer. These questions make concrete which sustainable choices your business offers.

AI search engines decide independently which businesses they show and recommend. Cogundi helps them understand Castor better, but cannot guarantee visibility or a recommendation.
