A well-maintained participant panel is more than a time-saver. It sets your team up for better research from day one. The people you recruit and how you track, segment, and manage those relationships over time directly shapes how reliable your findings are.  

‍

With the right setup in place, you can move forward with confidence, knowing that these participants meet your criteria, aren’t overused, and can bring fresh perspectives to each study.

‍

Tools like Rally UXR bring that structure to participant recruitment. It helps you build and manage your own participant panel, keep track of consent and contact history, coordinate logistics, and stay on top of all the moving parts. You can also see things like incentive history and email engagement, making it much easier to decide who to invite and when.

‍

But recruitment is just the starting point. The real value comes next: running the research and turning participant feedback into insights you can actually use.

‍

‍

‍

Using Rally + Optimal together

Whether you’re running unmoderated studies, testing designs, navigation, or content, or conducting usability testing calls, having the right research tools in place is critical. If you’re already using Rally, pairing it with Optimal can connect the dots from recruitment through to insights, without adding friction to your workflow.
‍

You can also use Optimal’s on-demand or custom managed recruitment services, though Rally’s strength lies in building your own custom panel and database.
‍

Here’s how to combine Rally and Optimal into a smooth, efficient research workflow.
‍
‍

Start with intentional recruitment

Define your participant criteria in Rally. Use screening questions not just to qualify participants. Think beyond “does this person qualify?” and start building segments you can reuse: power users vs. casual users, returning users vs. first-timers, people familiar with the old design vs. new. These segments can make it easier to run focused studies and compare results over time.

‍

Build your study in parallel

A simple shift that makes a big difference: don’t wait. Build your study in Optimal before sending invites from Rally. This ensures that when participants are ready, the link can be dropped into Rally, and distribution happens the moment you're ready.

‍

Use the strengths of each platform

Rally handles the relationship and profile management: who's been invited, who's confirmed, who needs a reminder, screener and survey history, consent forms, and more. Optimal handles the research: collecting quantitative and qualitative data, visualising patterns, quantifying usability issues, automating insights with AI, and surfacing the metrics and insights that actually answer your research question. 

‍

With Optimal, you can immediately put Rally-recruited participants into studies including:
‍

• Prototype testing
• Live site testing 
• Card sorting
• Tree testing
• First-click testing
• Surveys
  ‍
  ‍

Keep your insights in one place‍‍

When it comes to research, scattered insights = lost impact. Using Optimal as your central hub for results, recordings, and analysis makes it easier to share findings with your team and stakeholders, track progress over time, and back up decisions with real evidence. 
‍

The tools you use for recruitment and the tools you use for research aren't just operational choices. They shape your research culture. When recruitment and research are both well-structured, everything runs more smoothly. Teams that invest in structure on both ends of the workflow tend to produce research that's faster, more credible, and more likely to influence decisions. 
‍

Rally and Optimal are powerful on their own. Together, they create a workflow that’s scalable, insight-driven, and built for continuous discovery.

If you're not yet using Optimal, you can start a free trial or book a demo.

Recruiting the right participants is one of the biggest challenges teams face when conducting user research. Poor quality or disengaged testers can lead to unreliable data. While bottlenecks in recruitment – long lead times and limited access – can delay studies, reduce research frequency, and slow product development. 

‍

Having flexible options helps you keep moving at pace. Whether you bring your own participants, use Optimal’s recruitment services, or leverage external panel providers, Optimal gives you the flexibility to recruit the right user testers consistently and efficiently so you can launch studies faster, run them more frequently, and quickly scale research across multiple projects.

‍

Here’s a breakdown of your recruitment options with Optimal:

Recruitment Flexibility and Quality

‍

You’re never locked into a single approach with Optimal. Instead, you can adapt your recruitment strategy to each study, balancing speed, quality, budget, and scale, while using the same research and user insights platform.

‍

From shareable study links to easy panel workflows and expert support when you need it, you can spend less time managing recruitment and more time gathering actionable user insights.

As product managers, we all know the struggle of truly understanding our users. It's the cornerstone of everything we do, yet the path to those valuable insights can often feel like navigating a maze. The endless back-and-forth emails, the constant asking for favors from other teams, and the sheer time spent trying to find the right people to talk to, sound familiar? For years, this was our reality. But there’s a better way, Optimal's participant recruitment is a game-changer, transforming your approach to user research and freeing you to focus on what truly matters: understanding our users.

‍

The Challenge We All Faced

‍

User research processes often hit a significant bottleneck: finding participants. Like many, you may rely heavily on sales and support teams to connect you with users. While they were always incredibly helpful, this approach has its limitations. It creates internal dependencies, slows down timelines, and often means you are limited to a specific segment of our user base. You frequently find ourselves asking, "Does anyone know someone who fits this profile?" which inevitably leads to delays and sometimes, missed crucial feedback opportunities.

‍

A Game-Changing Solution: Optimal's Participant Recruitment

‍

Enter Optimal's participant recruitment. This service fundamentally shifts how you approach user research, offering a hugely increased level of efficiency and insight. Here’s how it can level up your research process:

‍

• Diverse Participant Pool: Gone are the days of repeatedly reaching out to the same familiar faces. Optimal Workshop provides access to a global pool of participants who genuinely represent our target audience. The fresh perspectives and varied experiences gained can be truly eye-opening, uncovering insights you might have otherwise missed.
• Time-Saving Independence: The constant "Does anyone know someone who...?" emails are a thing of the past. You now have the autonomy to independently recruit participants for a wide range of research activities, from quick prototype tests to more in-depth user interviews and usability studies. This newfound independence dramatically accelerates your research timeline, allowing you to gather feedback much faster.
• Faster Learning Cycles: When a critical question arises, or you need to quickly validate a new concept, you can now launch research and recruit participants almost immediately. This quick turnaround means you’re making informed decisions based on real user feedback at a much faster pace than ever before. This agility is invaluable in today's fast-paced product development environment.
• Reduced Bias: By accessing external participants who have no prior relationship with your company, you're receiving more honest and unfiltered feedback. This unbiased perspective is crucial for making confident, user-driven decisions and avoiding the pitfalls of internal assumptions.

‍

Beyond Just Recruitment: A Seamless Research Ecosystem

‍

The participant recruitment service integrates with the Optimal platform. Whether you're conducting tree testing to evaluate information architecture, running card sorting exercises to understand user mental models, or performing first-click tests to assess navigation, everything is available within one intuitive platform. It really can become your one-stop shop for all things user research.

‍

Building a Research-First Culture

‍

Perhaps the most unexpected and significant benefit of streamlined participant recruitment comes from the positive shift in your team's culture. With research becoming so accessible and efficient, you're naturally more inclined to validate our assumptions and explore user needs before making key product decisions. Every product decision is now more deeply grounded in real user insights, fostering a truly user-centric approach throughout your development process.

‍

The Bottom Line

‍

If you're still wrestling with the time-consuming and often frustrating process of participant recruitment for your user research, why not give Optimal Workshop a try. It can transform what is a significant bottleneck in your workflow into a streamlined and efficient process that empowers you to build truly user-centric products. It's not just about saving time; it's about gaining deeper, more diverse insights that ultimately lead to better products and happier users. Give it a shot, you might be surprised at the difference it makes.

‍

What's new…

‍

Speeding up task analysis in Treejack 🚤

‍

Customer feedback and research have shown that users analyse results in Treejack in a task-by-task manner. To better support this way of working, we’ve updated Treejack results to ensure the success and directness of each task are easier to compare with the new Task overview tab in Results.  This new visualisation is available in Results > Overview> Task overview section in Optimal Workshop.

‍

‍

Aggregate path views 

‍

We have also introduced the aggregate paths view in the Paths tab (it used to only be visible via the compare tasks button). This allows users to more easily see what the popular paths are for each task and how much each successful path was used (or not). 

‍

Over the next few months, we’ll continue working through our results tabs to update them to a task-by-task view and highlight insights at a task level. 

‍

Improving the quality of participant recruitment

‍

We’re continuing work to improve the quality of participants recruited in Optimal Workshop. Our latest release involves eliminating all participants that rush through a Treejack study.  We’ve analysed years of participants to get a good idea of what ‘rushing’ means, and we can now identify these ‘speeders’ and remove them from our participant pools. We have also removed the limit in-app for replacement participants across all study types, and released updates to immediately eliminate poor quality participants from custom orders. 

‍

Help guide: How to replace study participants in-app

‍

What’s next:

‍

• Identifying participants that rush through other tools and remove from participant pools.
• Build more automated flagging and behaviours to eliminate other behaviours that indicate poor-quality participants.
• Continued monitoring and analysis to ensure high participant quality.

‍

Templates are here 🙌 

‍

We are excited to announce our first six project templates are now available. Templates have been created with industry experts to give you the confidence to quickly launch studies and back your results to make data-driven decisions.   These ready-made templates give you a headstart on your research by providing you with the right range of study types and when to use them.

Our product team have begun discovery on improving our administration features, and have had a lot of great customer feedback to help shape up the opportunities. We are aiming to make improvements to this area of the product later this year.

If there’s one universal truth in user research, it’s that at some point you’re going to need to find people to actually take part in your studies. Be it a large number of participants for quantitative research or a select number for in-depth, in-person user interviews. Finding the right people (and number) of people can be a hurdle.

‍

With the right strategy, you can source exactly the right participants for your next research project.

‍

We share a practical step-by-step guide on how to find participants for user experience research.

‍

The difficulties/challenges of user research recruiting 🏋️

‍

It has to be acknowledged that there are challenges when recruiting research participants. You may recognize some of these:

‍

• There are so many channels and methods you can use to find participants, different channels will work better for different projects.
• Repeatedly using the same channels and methods will result in diminishing returns (i.e. burning out participants).
• It’s a lengthy and complex process, and some projects don’t have the luxury of time.
• Offering the right incentives and distributing them is time-consuming.
• It’s hard to manage participants during long-term or recurring studies, such as customer research projects.

‍

We’ll simplify the process, talk about who the right participants are, and unpack some of the best ways to find them. Removing these blocks can be the easiest way to move forward.

‍

Who are the right participants for different types of research? 🤔

‍

1. The first step to a successful participant recruitment strategy is clarifying the goals of your user research and which methods you intend to use. Ask yourself:

• What is the purpose of our research?
• How do we plan to understand that?

‍

2. Define who your ideal research participant is. Who is going to have the answers to your questions?

‍

3. Work out your research recruitment strategy. That starts by understanding the differences between recruiting for qualitative and quantitative research.

‍

Recruiting for qualitative vs. quantitative research 🙋🏻

‍

Quantitative research recruiting is a numbers game. For your data analysis to be meaningful and statistically significant, you need a lot of data. This means you need to do a lot of research with a lot of people. When recruiting for quantitative research, you first have to define the population (the entire group you want to study). From there, you choose a sampling method that allows you to create a sample—a randomly selected subset of the population who will participate in your study.

‍

Qualitative recruiting involves far fewer participants, but you do need to find a selection of ‘perfect’ participants. Those that fit neatly into your specific demographic, geographic, psychographic, and behavioral criteria relevant to your study. Recruiting quality participants for qualitative studies involves non-random sampling, screening, and plenty of communication.

‍

How many participants do you need? 👱🏻👩👩🏻👧🏽👧🏾

‍

How many participants to include in a qualitative research study is one of the most heavily discussed topics in user research circles. In most cases, you can get away with 5 people – that’s the short answer. With 5 people, you’ll uncover most of the main issues with the thing you’re testing. Depending on your research project there could be as many as 50 participants, but with each additional person, there is an additional cost (money and time).

‍

Quantitative research is obviously quite different. With studies like card sorts and tree tests, you need higher participant numbers to get statistically meaningful results. Anywhere from 20 - 500 participants, again coming back to the purpose of your test and your research budget. These are usually easier and quicker to implement therefore the additional cost is lower.

‍

User research recruitment - step by step 👟

‍

Let’s get into your research recruitment strategy to find the best participants for your research project. There are 5 clear steps to get you through to the research stage:

‍

1. Identify your ideal participants

‍

Who are they? What do they do? How old are they? Do they already use your product? Where do they live? These are all great questions to get you thinking about who exactly you need to answer your research questions. The demographic and geographic detail of your participants are important to the quality of your research results.

‍

2. Screen participants

‍

Screening participants will weed out those that may not be suitable for your specific project. This can be as simple as asking if the participants have used a product similar to yours. Or coming back to your key identified demographic requirements and removing anyone that doesn’t fit these criteria.

‍

3. Find prospective participants

‍

This is important and can be time-consuming. For qualitative research projects, you can look within your organization or ask over social media for willing participants. Or if you’re short on time look at a participant recruitment service, which takes your requirements and has a catalog of available persons to call on. There’s a cost involved, but the time saving can negate this. For qualitative surveys, a great option can be a live intercept on your website or app that interrupts users and asks them to complete a short questionnaire.

‍

4. Research incentives

‍

In some cases you will need to provide incentives. This could be offering a prize or discount for those who complete online qualitative surveys. Or a fixed sum for those that take part in longer format quantitative studies.

‍

5. Scheduling with participants

‍

Once you have waded through the emails, options, and communication from your inquiries make a list of appropriate participants. Schedule time to do the research, either in person or remotely. Be clear about expectations and how long it will take. And what the incentive to take part is.

‍

Tips to avoid participant burnout 📛

‍

You’ve got your participants sorted and have a great pool of people to call on. If you keep hitting the same group of people time and time again, you will experience the law of diminishing returns. Constantly returning to the same pool of participants will eventually lead to fatigue. And this will impact the quality of your research because it’s based on interviewing the same people with the same views.

‍

There are 2 ways to avoid this problem:

‍

1. Use a huge database of potential participant targets.
2. Use a mixture of different recruitment strategies and channels.

‍

Of course, it might be unavoidable to hit the same audience repeatedly when you’re testing your product development among your customer base.

‍

Wrap up 🌯

‍

Understanding your UX research recruitment strategy is crucial to recruiting quality participants. A clear idea of your purpose, who your ideal participants are, and how to find them takes time and experience. 

‍

And to make life easier you can always leave your participant recruitment with us. With a huge catalog of quality participants all at your fingertips on our app, we can recruit the right people quickly.
