No scores and no ranking. Every profile is the supplier’s own description, dated, and you choose who to approach.
When a brief needs an audience outside your usual reach (a low-incidence patient group, a niche B2B role, a difficult market), the hard part comes before any fieldwork: working out who can even deliver it.
Today, buyers are stuck between two poor options
Membership and industry directories tell you which companies exist and who belongs to an association, but not who can reach your audience. You still open twenty tabs, read twenty differently-written profiles, and email each one to ask.
So most teams fall back on memory: the same few suppliers, study after study, plus whatever colleagues suggest and whatever's buried in old project files.
Either way, you’re limited to who you already know. Good audiences get called “hard” or “not feasible” when the right supplier was simply never found.
A public directory is organized around companies: you look a firm up, or scroll a membership list. That’s useful for checking who exists. It isn’t built to answer the question a buyer actually has:
“Who can reach this specific audience, in this market, for this study?”

Open Network is organized around your requirement
Instead of browsing companies, you search by the things that decide feasibility:
You see the suppliers who match, described the same way so you can compare them side by side.
The result: a shortlist that used to take a week of emails takes an afternoon.
Open Network organizes supplier information around what researchers actually need to know.
Combine filters to move from “who might work” to “who actually fits” in a few clicks.
The reason a directory leaves you emailing everyone is that no two listings describe themselves the same way. Open Network fixes that by structuring every profile identically, so you can weigh what matters for your study without translating between formats.
Each profile shows
Company
Who they are and where they operate.
Audience
Who they say they can reach.
Geography
Where they can provide sample.
Supply model
How their sample is sourced.
Specializations
Where they have particular audience or market expertise.
Technology
How they connect to your research workflow.
Quality approach
How they describe their own recruitment and respondent-quality practices, clearly marked as supplier-provided.

Supplier’s own description, not a verified standard
Comparable structure is the whole point: you’re comparing fit, not deciphering ten different capability decks.
Open Network is transparent about what you're looking at. Profile information is supplier-provided and labelled as such, with a last-updated date so you know how current it is.
There are no public scores and no rankings, because “best supplier” only means something relative to your audience and timeline. Open Network gives you comparable, structured information as the basis for a better-informed conversation.
You make the call; we just make sure you’re making it with more than an inbox and a hunch.
Profile information comes from the supplier, and is labelled as such.
A date on every profile, so you know how current it is.
You decide who to contact, who to shortlist, and who to use. When results are filtered or sorted, we show you exactly what they're sorted by. The controls are yours, not a judgement we make on your behalf.
Open Network is not designed to tell you
“Supplier A is better than Supplier B.”
It’s designed to help you answer
“Which suppliers are genuinely relevant to my requirement?”
A directory is somewhere you look something up and leave. Open Network is the front of getting a study done, and the rest is there when you want it.
