You built something. Now you need to know if it works.

You vibe-coded an app on Claude or Cursor for real estate agents. You shipped a landing page on Lovable or Figma for dietitians. Building has never been easier. Finding real target users to give you honest feedback hasn't caught up.

Your options today are not great:

Friends & familyLove you. Often sugarcoat.

Your own networkPolite, not always honest.

Expert networksOut of budget.

Generic panelsAnonymous, unverified.

None of those are your target audience giving you honest signal. That's where this falls apart for most builders, not in the building, but in the feedback. We fix that.

In-depth interviews

1:1 conversations, via video or WhatsApp.

Surveys

Quantitative samples, with quality controls built in.

Diary studies

Longitudinal research, particularly strong over WhatsApp.

Concept testing

Show people what you've built and capture real reactions.

Prototype tests

Get your Figma, Lovable or Cursor build in front of real targets.

AI evaluation

Human input for model behaviour, output quality, and alignment.

When to use Kosmo

Discovery research

You're early, exploring a problem, validating a market, understanding how people actually behave today. We recruit the people who genuinely have the problem.

Validate what you've built

You've shipped a landing page, prototype, or v1. Get real target users to react to it and tell you what they actually think.

Niche audiences

Specific role, seniority, industry, or geography that generic panels can't find. We filter by what LinkedIn actually shows, not panel self-reports.

How it works

Brief us

Who you need to reach, how many, by when.

Design the screener

Tight criteria so only the right people make it through.

Recruit & verify

LinkedIn-sourced, individually checked against your criteria.

Run the study

You run it yourself, or we run it for you.

Frequently asked questions

Every participant goes through a verification chain. We start with a LinkedIn profile check covering real name, current role, company and work history. We match their role and seniority against your brief. Each participant then completes a custom screener with must-have criteria, disqualifiers and consistency checks. In-study quality controls catch anyone trying to game the process. Every quarter, we recalibrate profiles so the people you recruit against are still in the roles they said they were.

We recruit through targeted LinkedIn campaigns and a verified contact network built up across multiple studies. Every candidate is screened against the specific brief before being invited to participate, rather than pulled from a stale general list.

The US, Canada, the UK, Europe, and Southeast Asia, including Indonesia, Vietnam, the Philippines, Malaysia, and the wider region. Other markets are possible by brief.

Yes. Verified humans giving structured feedback on AI outputs, model behaviour or alignment is a growing use of the panel.

Pricing is project-based, scoped to your study. You only pay for participants who pass screening, never for no-shows or screen-outs. Book a call and we'll scope it together.

Tell us. The panel grows by brief, and most of what we recruit was a "can you do X" request before it became a vertical.
