Teams leave a user testing engagement with a prioritised research report — failure points identified, severity rated, and specific design recommendations ready for the next sprint.
We run moderated and unmoderated sessions on prototypes or live products, scoped to the flows your team most needs to validate.
3 main challenges holding back your growth
Outgrown identity
Your company has grown, but the brand no longer reflects scale or direction.

Testing after shipping
Decisions made without user data — costly fixes found only after release.
Internal bias in testing
Teams test internally — real friction never surfaces before launch.
No structured method
Feedback gathered but unstructured — no patterns, no priorities, no action.
“All projects in which we’ve involved Halo Lab have been great successes, but their leadership on our brand refresh is worth highlighting.”
“We’ve had feedback from users, investors, and employees, and everyone has said that Halo Lab did a fantastic job with the branding.”
“We’re proud of their branding services. They not only do what we tell them but also make suggestions to help us improve our offerings.”

FAQ
Why invest in branding services?
Why invest in branding services?
What is user testing?
Moderated and unmoderated usability sessions, prototype testing, tree testing, card sorting, expert review, and a prioritised research report with severity ratings and design recommendations.
How many users do you test with?
Most usability studies use 5 to 8 participants per user segment. More participants are recommended for quantitative studies or products with multiple distinct user groups.
What is moderated vs unmoderated testing?
Moderated testing is researcher-facilitated with live observation and follow-up questions. Unmoderated testing is self-guided and remote, using a defined script. Both formats are scoped to your research goals.
Can you test a prototype before it is built?
Yes. We test Figma prototypes, staging environments, and live products — scoped to the flows and decisions most critical to your current design phase.
How long does user testing take?
Most user testing engagements take 2 to 3 weeks from brief to final report, depending on recruitment complexity, number of participants, and session format.
Do you provide fix recommendations too?
Yes. Every engagement includes a structured research report with prioritised findings, severity ratings, recorded clips or highlights, and specific design recommendations.
Can you test against a competitor product?
Yes. Comparative usability testing against a competitor product or previous version helps frame findings relative to your competitive context.
Do you recruit participants or do we?
Both options are available. We write screener criteria and recruit through our panel network, or we can work with a participant list you provide.
Do you offer ongoing testing support?
Yes. We can run follow-up sessions to walk through findings, prioritise recommendations, and align on design actions before the next sprint begins.
