Hi, My name is Dr. Anna Pursaud and I'm the CEO of this Works and I'm very happy to be here with you today at marketingland Festival and be part of the Marketing brand track. So I know I'm the end of probably a really interesting, fantastic day and thank you for staying with us. And my job today is to talk to you about how I built this Works, which is a science first wellness brand, and how we the journey we've been on, the challenges we face, and some of the key milestones as we've journeyed for what is over 22 years. This works is a British brand. We are located in Wimbledon. You may have heard of Wimbledon, where the tennis takes place. So if you ever come to come to London, come visit. That's where where we are. But we are an international brand in terms of our distribution. So over the last 22 years it has been really important for me as a CEO and also founder to be very clear about what we are trying to achieve as a brand, to really identify why we dare show up on what is actually a very competitive stage, a very, very crowded space with very large budgets from some of the players in our market. So why do we deserve to be there? What are we offering the consumer? And actually, for a brand to be still very much fighting and succeeding in the wellness category after 22 years, you've got to have a reason for that. So we are the brand that put sleep on the map. I hope that you are all very much taking care of your sleep because I hope by now you are aware of the very fundamental link between sleep and wellness and sleep and skin health. But when I first created a sleep range, that knowledge was not at all common. Sleep was very much something people downplayed. It was about the culture. Busy. How busy am I? How much. How much time can I devote to work? It was when we started to use devices for emails, and people were enjoying the fact that they could take their work home with them. And there was an evolving culture around how much can they do in a day? But because of my background as a scientist, and I'll come on to talk about that more, I knew that actually sleep was fundamental to how we looked. And we are a cosmetics and beauty brand. And it was that insight, that first belief that actually if we focus on our sleep, we can improve our skin. That was a white space that at the time, nobody else had identified. So we are very much pioneers. And when you're a pioneer, you've got to have a. You've got to have a set of beliefs. You've got to be able to believe in something because you haven't got a playbook to follow. And my belief, because I'm a PhD biochemist, is that the way that our biology is governed, the way the body clock, you may have heard of the body clock, the circadian rhythm, the way that that runs, affects directly how we, how we feel, our health, how we look. Everything is governed by this internal body clock. And so I wanted to create a brand that was rooted in the fundamentals of biology. Understanding that link between biology and skin health and how we, how we look and how we perform is fundamental to the building a brand and identifying the purpose. So building a brand with purpose, I think everyone's very familiar with that concept because that's what consumers identify with, and it is what gives the brand resilience. In my opinion, building something that, you know, identifies with what people are looking for, your core consumer. And for us, it was about creating solutions, solving problems that they maybe didn't even know they had. So 20 years ago, this the problem that we could see coming down the line was people's inability to sleep well and manage their stress. So the purpose is grounding grounded in creating solutions that improved people's lives. And so everything we do as a business is very much connected to this core belief. And the promise is the name, the name above the door. This works. And as a scientist, for me, that meant that we had to create a NPD process, a marketing strategy, a common strategy that really lived up to the name. So if you're going to Say a brand is called this way, you better evidence that. And so if you look into the brand DNA, if you look into our communication, if you look at what we do, what I talk about, it is very much rooted in the evidence, the pipeline of R and D that we've created, the experts that we work with, the trials that we've conducted. And over the years this has accumulated in order to build a very, very high level of brand trust. What that looks like today. Our impact is that we are the number one sleep brand in the uk. I built the category of pillow sprays. We were the first to launch, and there are now many others in the space. And that is a challenge that I can address. The need to keep innovating is very much, you know, priority for a brand that creates a category and wants to continue to lead it. We are considered, if you will, we do our brand health trackers because, you know, I can say we're highly regarded for the trust and having efficacious products. But you have to evidence that, right? So doing regular studies to help you understand whether that is indeed true. And we do that, we put our products forward for industry assessment all the time, consumer testing, expert testing, and we've won over 200 awards. So again, proof points, really important. We've taken our concept into over 50 countries. Excuse me. So proof, proof pointing the brand. Once we identified that sleep and creating sleep products resonated in our own markets, we took this into overseas markets. A nice little soundbite. We sold over 12 million sleep sprays. And so we've helped thousands of people. And they create stories. They create emotional stories about how our products have helped them with their sleep and with their health and with their lifestyles. And again, that's very powerful when you're trying to create a brand that resonates not just for its trusted products, but also because of its emotional resonance. And then a point about the brand that I'm very proud of is a number of studies that we've done. So even though we are a small brand, we have prioritized proof pointing through science, the claims behind the brand. So just to come back to the pillars that we've built our brand upon and, you know, back to building brands that survive the test of time. Okay, the pillars that we've picked are efficacy and trust. The priority for us in terms of resources and where we first, where I first started was to build products that could really stand up in their own right against the big guys, against the big players. So that meant doing product development studies that ensured that when the products were signed off, they actually could live up to the claims that they were making. So I brought in a protocol which involved using large user studies, testing panels, then moving to clinical studies measuring skin change, and then clinical studies measuring sleep and sleep architecture, which evolved into neuroscience, using the brain and using the nervous system to assess the impact of our products and our fragrances on the brain. So this commitment to studies and science has really given us, given the brand, a very strong pillar that we lean upon. And the other side of that is trust, because of the work that we've done in terms of validating the claims and providing people with reasons to believe they trust us. So it's our job then to make this information available, to be able to communicate it effectively. And that's one of the things I've learned over the last 20 years, is how people like to assume and consume their information. So science today is delivered in a very different way than it was, say, five years ago. And it's very much a challenge for all of us, isn't it, to keep our communication relevant. So whether you're putting it in little snackable content on TikTok or you're doing two hour podcasts, is making sure that your content is relevant for the different channels and the different consumers and then also using the industry. So in our industry, cosmetics executive, women, CEW in the US is very powerful also in the uk, but also other industry stances where people can find you and think, yes, okay, this is a brand that I trust. So if we go back a little bit into the science and rooting the brand in something that gives it resilience, that gives you the right to show up and be authentic. For us, it was around understanding chronobiology, which is back to the circadian rhythm, understanding the fact that the body runs on this body clock that's anchored in actually part of the brain called the chiatic nucleus, but actually all of our organs and even our skin cells have a little clock. And that clock controls what happens when. And for me as a scientist, that was very much a opportunity to create a product range that could support circadian rhythm. So it was about finding an authentic scientific fact that I could then build my brand upon, as opposed to making something up which, you know, would not stand the test of time. And so I'm just going to dial in now to some of the products that we are best known for, just as part of my case study to explain how the brand has evolved over time. You know, why have we won all these awards? Why have we got, you know, the sales in over 50 countries and that's to do with these pillar sprays. Being known for something is important. Being the best in class, being the gold standard and really anchoring your, your, your investment at the beginning, especially if you're a small brand on something that can really cut through the noise. And for us it was the launch of these pillow sprays. So we have more than one pillow spray, but we started off with the one which is to help people get to sleep. So can't get to sleep. This is the Deep Sleep pillow spray. This is one that, you know, we've got the most recognition for if you like. We've got the biggest revenue in sales. We know with a number one sleep brands in Amazon in the uk. You know, we do a very significant amount of revenue through this sleep, this Deep Sleep pillow spray. But we also had to create other products which would help people because if you're an expert in a category, you have to be able to create other products that support different needs that people might have because not everybody's sleep problem is the same. And so on the left hand side, can't stay asleep. We created that product for people that wake up in the night and it's a more sophisticated version. It's got an end cap delivery system and it's also a more expensive product. So just as an example of taking the spray and then building a category out of it. So here we can see that in fact we've also got products for babies. So if you're somebody that's trying to train a baby, train a baby, I say that with respect. You know, babies are going to take their time, that's natural. But you can use fragrance to help them as a cue. So we launched the Baby Sleep spray. We also have one for intimacy. Now that, that, that was an example of innovation which didn't work. It was a little bit too early. So the Love of Sleep Pillow spray is a fragrance that was created using brain imaging in order to understand how we could help people to relax and be more pro social. Right. So help to pave the way to intimacy, both sexual intimacy and connectivity between, you know, family members. It's all about just reducing the barriers. People are very socially isolated. So this, with, this is an example of a fragrance that's very technical. It's got some really great evidence behind it, but it was a little bit too soon and our consumer wasn't really ready to be told that this was going to help them to have sex. So we discontinued it. But you know, it's really important not to be frightened about failing as long as you fail fast and you move on. And on the left hand side you can see just some evidence, some other proof points to help me sit here in front of you and say, look, I'm the leader in the category because we've got studies with over 1000 people. These are independent studies conducted by experts, nothing to do with me and my own database. The clinical part and the FMRI part I'm really proud of because these were academic research that was done, we published off the back of it. So, you know, collaborating with scientific institutions has been part of our success. And that was me leveraging my scientific background. And I would say to you, you know, as marketeers and as business people, use what you've got, use your own skill. Whatever you are particularly good at, whether that's, you know, networking, you may, you may have an artistic background, you may be brilliant in social media, you might be a scientist like me. Use what you've got, like go hard in those areas. It will give you a competitive advantage. So yes, this works as me as a CEO, yes, I'm a biochemist and yes, I'm also in industry. You know, I've been here a long time. But it's also important to surround yourself by other experts and, you know, you can't know everything. I learned that early on. Make sure you surround yourself with other people that know more stuff than you do. And in terms of science and wellness, we are lucky enough to collaborate with obviously our professor of neuroscience, Gabby Bezer, who does the research. But also we work with a roster of experts, experts. Some of them would be high social media kind of people that they bring in their own, their own community. But others are just normal people that have a purpose and have something to say. And I think sometimes it's really important to also include your community that not for reasons of reach but for reasons of authenticity and relevance. And so just as I move towards the end of my presentation, I think the last thing I want to say is really about the need to continue to be relevant and build your storytelling as the seasons and the years change. So I started my career back in the 90s and I was very much in luxury goods and it was very much about, you know, labels and spending, you know, large amounts of money of over packaged goods. I'm now here today talking about sleep and the evening economy. I spend my time listening to and understanding people's concerns about, you know, how they can't switch off and why they're stressed at night. And why their evenings don't feel relaxing anymore. So these trends, and they're not trends, they're becoming big cultural shifts are my business. And I think that when you take a brand you need to be really clear about what, what its relevance is and how is your brand going to, you know, weave itself into people's lives. And here's just, you know, the some points, I'm sure you'll, you'll know them too around how our lifestyles today are so impacted by our inability to switch off, to put our devices down. And so a brand that this works has become even more relevant in sleep and wellness as this, as the struggles against technology and an always on society and the stressors around us have grown, my brand has become more and more relevant. But it's my challenge to have to tell those stories in a way that they can understand, that is relevant and also point to know I'm not the only brand in this space. Because if we, you know, we talk about what is called the evening economy and it's big, you know, the consumers are building rituals, they're building protocols for themselves to help them in the evening and it says significant revenue. In fact they refer to it as the bedtime economy. 585 billion. Right. That's big. So I'm sitting in this space now with lots of other brands and it's my job to continue to innovate, to tell stories that are relevant. So just you know, as we, as we look into the future for this work. So I'm calling upon my scientific background, my knowledge of sleep, listening to my consumers, understanding their stressors and it's really important for brands to then, you know, follow them, where are they going and what do they need? So for us actually that is a fine fragrance that is based on terpene science, based on the research we've been doing with our brain and neuroscience and taking into a new adjacent category. So just to finish, this is where I'm going to leave you with just, you know, just a few stats to support everything I have said. You know, today we're sitting here with the number one cheap brand with lots of proof points here. But as I said, I think really the journey, the point I want to make is that building a brand based on scientific credibility, based on authority and then just continuing to show up in a persistent and consistent way is I think today while we're still here doing what we do with so much love and passion. Thank you.

In this special episode of The Marketing Millennials, Daniel Murray features a talk from Marketingland Festival 2025 with Dr. Anna Persaud, CEO and founder of This Works—a pioneering British wellness brand famous for creating the "pillow spray" category. Dr. Persaud details how she built a science-first, purpose-led brand that has thrived for over 22 years in a crowded market dominated by much larger players. The conversation covers brand purpose, the power of scientific credibility, how to earn and maintain consumer trust, innovation, failure, and evolving with cultural shifts.
(02:00–07:30)
Origin Story & White Space:
Dr. Persaud explains that sleep and its impact on wellness and skin health were overlooked in early 2000s culture, which glorified being busy and neglected sleep.
“It was about the culture. Busy. How busy am I? How much time can I devote to work?...But because of my background as a scientist...I knew sleep was fundamental to how we looked.” (03:45–04:20)
Pioneering Mindset:
The lack of an industry “playbook” for sleep wellness meant inventing their own rules and holding strong beliefs rooted in her scientific expertise.
Purpose as Resilience:
Building a brand with a clear, problem-solving purpose gives it the resilience to last.
(07:30–11:00)
Building Brand Trust via Evidence:
The name ‘This Works’ set a high bar—requiring everything from R&D pipelines, clinical trials, expert validation, and accumulating consumer trust through proof points.
Proof Points and Impact:
Continuous Innovation:
Importance of innovating to stay ahead after creating (and hence inviting competitors to) a new category.
(11:00–14:30)
Rigorous Product Development:
Progressing from large user studies to clinical trials—first on skin, then on sleep, even to neuroscience (e.g., studying brain reaction to fragrances).
Communication Evolution:
Adjusting how scientific proof is communicated, from snackable TikTok content to longform podcasts, to remain relevant to different audiences.
(14:30–16:00)
(16:00–18:10)
Deep Sleep Pillow Spray:
The foundational and bestselling product—served as the launching pad for category expansion.
Expansion and Experimentation:
Fail Fast, Move On:
Embracing innovation—even when products fail—as long as the company learns and adapts quickly.
(18:15–19:05)
Go Hard on Your Skills:
Tap into your unique strengths for competitive advantage—be that science, networking, creativity, or social fluency.
Surround Yourself With Experts:
Building collaborations with passionate experts, not just for social reach, but to enhance authenticity and relevance.
(19:10–21:00)
Adapting to Societal Trends:
The wellness market’s relevance has only grown as “switching off” gets harder—hence, brands must keep evolving their storytelling.
Bedtime (Evening) Economy:
Noting the significant market size (estimated at $585 billion) and the importance of storytelling and innovation as competition intensifies.
(21:00–end)
Relentless Consistency:
Building on scientific credibility, listening to consumers, innovating (e.g., developing scents based on terpene science), and showing up with “love and passion” for the brand.
Final Advice:
On being first and proof-driven:
“We are the brand that put sleep on the map ...When I first created a sleep range, that knowledge was not at all common.” (04:00)
On science as competitiveness:
“It's also important to surround yourself by other experts … Make sure you surround yourself with other people that know more stuff than you do.” (18:50)
On learning from failure:
“It's really important not to be frightened about failing as long as you fail fast and you move on.” (17:59)
On enduring relevance:
“As the struggles against technology and an always on society ... have grown, my brand has become more and more relevant. But it’s my challenge to have to tell those stories in a way that they can understand.” (20:20)
This episode provides a clear blueprint for marketing leaders aiming to build brands that earn lasting consumer trust, grounded in authentic purpose, robust scientific validation, relentless innovation, and honest storytelling.
