Specialist in recruitment for UX research
Whether you need participants once or conduct research all year round, we are your UX recruitment partner. We have specialised in this for 25 years, with a panel of 16,000+ people in the Netherlands and an extensive network.

Quality is our number one priority
We do not recruit professional participants who jump from one study to the next for the incentive. Our participants are genuinely engaged.
Specialists in both fast and complex recruitment
With a diverse panel of 16,000+ people in the Netherlands and an extensive international network, few briefs faze us.

Contact usYou focus on who you want to speak with; we do the rest
Your research stands or falls with the people on the other side of the table. Our recruitment process takes care of everything for you, while you always decide who you want to speak with.

We always think along with you
Our experienced project lead discusses the recruitment criteria with you and advises where needed. No filling in a form and waiting, but a sparring partner who thinks along with you from the start so you speak with the right people.

You choose; we make sure they are there
You decide who takes part using the schedule with participant profiles. We double-screen everyone and provide an online or on-site host on the research day: a 99% show rate and a free backup participant, just in case.

Arranged quickly, even under time pressure
Basic recruitment projects are often completed within a week. Facing a challenging deadline? We will activate our entire network to deliver on time, although we may need a few extra days.

Questions? Answers.
How many participants do I need for my research?
For one clearly defined target group, 5 participants are often enough to spot the most important patterns. This follows the well-known guideline from Nielsen Norman Group. Are you including groups with clearly different motivations or needs? Aim for 3 to 4 participants per group. Not sure? We’re happy to help you decide.
How quickly can you find a hard-to-reach target group?
Honestly? That depends on who you’re looking for. We know our large in-house panel well and also have an extensive network to tap into. Share your criteria with us and we’ll give you a realistic timeline straight away.
Do I arrange the participant incentives myself?
Nope. When we handle the recruitment, we transfer the incentives and reimburse any travel expenses. You don’t have to arrange a thing. Nice, right?
Is confidentiality guaranteed when I test a new concept?
Yes. Every participant accepts our participation terms, which include a non-disclosure agreement. So you can test a new concept with peace of mind.
Do you also recruit participants for accessibility research?
Absolutely! Through our trusted partners, we recruit people who are blind or partially sighted, deaf or hard of hearing, or have cognitive or motor disabilities. We can also recruit people with limited digital, administrative or health literacy.
Can you also recruit participants abroad?
Absolutely! Happy Labs is part of UX Fellows, an international network of 23+ research agencies. That gives us access to local participant recruitment in 55 countries, including Canada, the United Kingdom, South Korea, Germany, France, Spain, Japan, Australia and the United States. One point of contact, locally arranged.
