While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more

To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience. We recognise we may not catch everything, and you can flag anything you think we may have missed. Read more

Written by the company

The Happiness Index gives insights into why your people leave or stay, what drives productivity, and how that impacts your bottom line. We combine three things no other platform or consultancy can access: a proprietary neuroscience methodology that measures how people think and feel, 250 million+ data points on workplace engagement and happiness, and global benchmarking insights from The Global Workplace Happiness Report. As a result, you see how culture drives financial performance, why some teams fly and others stall, and exactly where to invest in your people.

A partnership built on trust and…

As CEO of Elfkare, where our mission is to help leadership teams unlock outsized performance by building trust in their people, I was really drawn in by Matt Phelan's vision. Having first come across The Happiness Index at their 10-year anniversary conference in November 2024, I was immediately hooked, unlocking the secrets of workplace happiness through neuroscience, backed by over 2 million data points from employees worldwide. It was clear that The Happiness Index is an organisation who believe, as I do, that trust in people is a hidden multiplier which businesses can tap into to achieve commercial growth.

When I heard The Happiness Index was working on the first ever Global Workplace Happiness Report, I jumped at the chance to get involved and reached out to Matt directly. Elfkare became the very first sponsor of GWHR Year Zero, launched in April 2026. It was a phenomenal experience, and I'm looking forward to Elfkare being a sponsor again in 2027.

What's kept me involved is the trust underpinning the relationship. Matt and his team have collected an extraordinary amount of insight into how people feel at work. I love the collaborative and open approach they adopt to working with partners to help companies deliver business performance through people.

If you're looking for a partner who shares that vision, I recommend reaching out to The Happiness Index.

Brilliant team. Worthwhile service

I've worked with The Happiness Index on multiple projects, and they've been fantastic. Professional, enthusiastic and brilliant collaborators. Their service isn't a nice-to-have. It dives into what really matters to your people and business.

I love working with THI

I honestly couldn't recommend THI highly enough. Every interaction has been positive, collaborative and genuinely enjoyable.
The team are incredibly knowledgeable, responsive and passionate about helping me with the journey I'm taking our organisation on.
They take time to understand what you are trying to achieve and challenge your thinking in all the right ways.
It feels like a true partnership rather than a supplier relationship. We have loved working with them and are excited to keep building on that!

You can teach people processes but you can't teach pure passion and I feel they embody that!

The Happiness Index (THI) - Thank you!

The Happiness Index (THI) has been an invaluable partner in helping us understand, measure, and strengthen our organisational culture. Their expertise, insight and genuine commitment to our success has enabled us to turn colleague feedback into meaningful action and informed decision-making. No question is ever too big, too small, or too complex; the team consistently takes the time to listen, provide clear guidance and respond thoughtfully. What has impressed us most is their responsiveness and willingness to help, always coming back to us quickly with practical advice, analysis, and support. Their collaborative approach has made them feel like an extension of our own team, helping us build a deeper understanding of our people and creating a stronger foundation for positive cultural change.

Not just surveys - insights into what drives performance

Have been a customer of The Happiness Index for years and love the insights we get from their employee engagement surveys. Platform is intuitive. Lots of thought has clearly gone into making the surveys comprehensive without being too long.

The icing on the cake is working with the team to dig deeper into what the data means and link it back to the financial performance metrics that our CEO is focused on.
