The SYYCO Story: 15 Years of Affiliate, Partnerships and People-First Growth

This year marks 15 years of SYYCO.

A lot has changed in that time. Affiliate marketing has evolved into a much broader partnerships ecosystem, the technology behind the channel has become more sophisticated, and the way businesses think about where, and how, people work has changed dramatically.

But for SYYCO, some things have remained remarkably consistent.

The agency was founded with a clear belief that brands deserved better support within affiliate marketing, and that a business could be built differently, around expertise, strong relationships, trust and flexibility.

Fifteen years later, those principles still sit at the heart of SYYCO.

Spotting a gap in the market

Before founding SYYCO, Simon Terry had spent much of his career working across travel, e-commerce and online businesses.

As more of the travel industry moved online, affiliate marketing was becoming an increasingly important part of the digital landscape. But it was also a very different channel to the one brands recognise today.

Simon had seen the challenges from the client side first-hand.

Smaller and mid-sized brands often lacked the support and attention they needed from affiliate networks, while specialist affiliate management agencies were few and far between.

At the same time, the industry itself was still finding its feet. Tracking was less sophisticated, compliance was less developed and there was far less structure around how brands, publishers and networks worked together.

Simon saw an opportunity to change that.

SYYCO was created to give brands the specialist expertise and hands-on support they needed to manage affiliate marketing properly, helping them build stronger relationships, protect their interests and ultimately get more from the channel.

What began as a consultancy quickly developed into something bigger.

As the client base grew, so did SYYCO’s understanding of what effective affiliate management really required.

Bringing together expertise from both the client and publisher sides of the industry helped shape the agency model that followed, with dedicated focus on both client strategy and partner relationships.

It was the beginning of the SYYCO we know today.

Affiliate marketing has changed, a lot

Simon describes the affiliate industry of 15 years ago as something of a “Wild West”.

The channel offered huge potential, but it was far less regulated and structured than it is today.

Over the years, affiliate marketing has matured significantly. Tracking has improved, compliance has strengthened and both brands and publishers have far greater visibility and protection.

The definition of a “partner” has also expanded enormously.

What was once heavily associated with cashback, loyalty and voucher code publishers now encompasses content partners, influencers, CSS, closed user groups, card-linked offers, brand-to-brand partnerships and many other models.

Affiliate marketing has become partnership marketing.

And as the industry has evolved, SYYCO has evolved with it.

Remote-first before remote was the norm

One of the most distinctive parts of the SYYCO story has little to do with affiliate marketing at all.

SYYCO has been a remote business since day one.

Today, remote and flexible working feel familiar. Fifteen years ago, they were far less common.

Initially, running SYYCO remotely made practical sense. It kept costs and risk lower and removed the need for an office that clients and partners did not necessarily need the agency to have.

But it quickly became something much more fundamental to the way the business operated.

Remote working allowed SYYCO to build a team around talented, experienced people who also needed flexibility in their lives.

That might mean balancing work with raising a family, caring responsibilities, another career or passion, or simply wanting greater control over how work fits into life.

The philosophy has always been simple: people should be able to do great work without work needing to take over everything else.

Long before conversations about hybrid working, flexible hours and work-life balance became mainstream, SYYCO was already building a business around trust and autonomy.

And importantly, that has not disappeared as working habits have shifted again following the pandemic.

Flexibility remains part of the culture rather than simply a policy introduced because circumstances demanded it.

A major turning point

Like so many businesses, 2020 became a defining moment for SYYCO.

At the time, the agency was heavily associated with the travel sector. When COVID brought large parts of the travel industry to a standstill, SYYCO needed to adapt quickly.

While the agency itself had historically been travel-led, the team brought experience from a much broader range of sectors.

Before joining SYYCO, team members had worked across affiliate, partnerships and digital marketing for major retail, finance and other consumer brands.

That collective experience became hugely important.

SYYCO was able to use it to diversify the agency, building relationships with brands in new sectors and broadening the client base beyond travel.

The result was an important evolution in the business.

As travel eventually returned, SYYCO was no longer simply a travel affiliate specialist. It had become a genuinely multi-sector affiliate and partnerships agency, with expertise spanning a much wider range of brands and industries.

What was an incredibly challenging period ultimately helped build a broader and more resilient SYYCO.

The things that haven’t changed

The industry may look very different today, but many of the principles behind SYYCO have remained the same.

Trust is one of them.

People are trusted to take ownership of their work, make decisions and bring their expertise to the table.

Flexibility is another.

SYYCO has always recognised that talented people have lives and responsibilities outside of their jobs, and that giving people greater autonomy does not need to come at the expense of high standards or great work.

Relationships matter too.

Whether it is with clients, partners or colleagues, SYYCO has always focused on building long-term relationships rather than simply delivering short-term activity.

That approach can be seen in the clients who return, the referrals the agency receives and the relationships that continue even when people move between businesses.

And perhaps most importantly, SYYCO has always been a business built around people.

For Simon, seeing the team develop and watching SYYCO help its clients grow are among the things he is most proud of after 15 years.

Fifteen years onsyyco team meet 2025

From an idea formed after spotting a gap in a still-developing affiliate industry to a multi-sector affiliate and partnerships agency, SYYCO has changed significantly over the last 15 years.

The industry will continue to change too.

New technologies, new partner models and new ways for brands to reach audiences will continue to reshape the partnerships landscape.

SYYCO will evolve alongside it.

But growth does not have to mean losing the things that made the business successful in the first place.

The aim is to keep combining specialist expertise with strong relationships, continue adapting to where the industry is going, and protect the culture of trust, autonomy and flexibility that has existed from the beginning.

Because after 15 years, perhaps the best way to describe SYYCO is that it was simply built differently.

And it still is.

Case Study: Lyle & Scott, SYYCO & Sientia

Case Study: Lyle & Scott, SYYCO & Sientia

Scaling new customer acquisition through banking channels

SYYCO and Lyle & Scott had a clear objective for Card-Linked Offers: unlock targeted new customer acquisition at scale, without adding operational complexity or compromising on measurement.

As a well-established, premium fashion brand, Lyle & Scott have a mature affiliate programme which is managed by leading management agency SYYCO. Having already seen significant growth with SYYCO, Lyle & Scott were keen to explore additional customer acquisition opportunities to further drive direct revenue. SYYCO recommended CLO as a way to access high-intent audiences inside banking apps at the point of spend. The opportunity was clear, but so were the challenges. Fragmentation across publishers, unclear attribution, and internal scepticism often prevent CLO from scaling beyond small tests.

That’s where Sientia came in.

From the outset the focus was on simplicity and control. Rather than navigating multiple bank integrations and commercial relationships, SYYCO were able to launch Lyle & Scott across some of the largest UK banking platforms through a single access point. At the same time, SYYCO ensured the activity was structured to sit cleanly alongside their existing affiliate setup, ensuring alignment across channels.

What could have been a complex, multi-partner rollout became a streamlined activation with one contract, one reporting framework, and one source of truth.

The early results quickly validated the channel.

A significant majority of transactions were driven by entirely new customers, with only a small proportion coming from existing or lapsed users. This wasn’t CLO acting as another retargeting layer, it was reaching genuinely incremental audiences. Banking environments introduced Lyle & Scott to customers they wouldn’t typically capture through traditional digital channels, all at the moment those users were actively spending.

Just as importantly, this acquisition came efficiently. The cost per new customer remained highly competitive for a premium fashion brand, and compared favourably to other performance channels. Rather than trading margin for volume, the programme delivered a steady flow of high-quality customers at a sustainable cost.

Under the surface, the data reinforced this story. Transaction volumes translated into a broad base of unique customers, rather than being driven by repeat behaviour, and average order values remained consistent with the brand’s wider performance. This signalled that the channel was not diluting customer quality, but instead extending reach.

A key factor in building internal confidence was visibility.

Through Sientia’s live reporting and analytics, the SYYCO team had a clear, real-time view of Lyle & Scott’s performance across banks, markets and customer types. This transparency allowed them to move beyond the typical “black box” perception of CLO and instead treat it as a targeted and measurable growth channel. Performance could be understood, shared with Lyle & Scott, and built upon.

This was further strengthened by the integration into their affiliate ecosystem. This ensured CLO activity sat within a familiar reporting and operational structure ensuring the channel complemented, rather than conflicted with, existing activity.

With strong foundations in place, the focus has now shifted to scale.

What began as a UK activation has expanded into a broader European strategy, with the programme now live across the UK, the Netherlands and Sweden. CLO is no longer a test channel for Lyle & Scott, it is an active part of their customer acquisition mix, supporting both online and in-store growth.

Crucially, this expansion hasn’t introduced additional complexity. The same centralised setup, reporting, and operational model continues to underpin the programme, allowing the SYYCO team to scale Lyle & Scott’s activity confidently and efficiently.

Lyle & Scott’s journey reflects a broader shift in how CLO is being adopted.

When executed correctly, it moves beyond experimentation and becomes a reliable, scalable source of incremental growth. By focusing on data quality, operational simplicity and clear measurement from day one, Sientia has enabled SYYCO and Lyle & Scott to turn a historically opaque channel into one that is built for long-term scale.

  • High new customer rates (~79%)
  • Efficient CAC (~£13.75)

Affiliate Marketing Jargon Explained (A Beginner-Friendly Guide)

Affiliate marketing is a brilliant growth channel, but it has one big problem: the language around it can feel like a barrier.

If you’ve ever found yourself nodding along to conversations about cookies, EPC, CPA and attribution while secretly thinking “I’m not sure what any of that means”, you’re not alone. We speak to numerous brands that recognise they want performance-led growth, but feel hindered by the jargon.

That’s exactly why we created our new resource:

Affiliate Marketing for Beginners: Breaking Down the Jargon

It’s a simple, practical guide designed to take the mystery out of affiliate marketing terminology. No overcomplicated explanations, no trying to sound clever. Just clear definitions, useful examples, and a straightforward view of how the channel actually works.

What’s inside the guide?

You’ll find:

  • A plain-English explanation of what affiliate marketing is
  • Who’s who in the channel (publisher, advertiser, network, agency)
  • How tracking and attribution work end-to-end
  • The key terms you’ll hear at launch and day-to-day
  • The main types of affiliates, and what they’re good for
  • A transparent look at what an affiliate agency does and what to expect when working with one

Whether you’re launching an affiliate programme for the first time, picking the channel back up after a slow period, or just want your team to feel more confident talking about it, this guide is a helpful place to start.

Why we made it

At SYYCO, we manage affiliate and partnership programmes for brands across retail, travel, lifestyle and more. We’ve been doing this for a long time, and one thing is always true: affiliate works best when everyone is on the same page.

Understanding the basics makes it easier to make good decisions, ask the right questions, and get more from the channel. This guide is our way of helping brands feel clearer and more confident, before they even get into strategy.

Succeeding in Retail Affiliate Marketing: Insights from Team SYYCO

Working with some of the UK’s most exciting retail brands has taught us a great deal about what works in affiliate marketing. There are opportunities everywhere, but also some challenges that can trip you up if you’re not careful.

We sat down with Jessica Ten-Kate, our Client Management team leader, and Marta Casero, our Partnerships & Insight Manager, to get their honest take on what retail brands need to know to build programmes that deliver results.

Your Partner Mix Needs a Proper Strategy

Here’s the thing about retail affiliate marketing: there’s no magic formula that works for everyone. The partners that will move the needle for you depend entirely on what you’re trying to achieve.

If you’re all about driving revenue and new customers, cashback sites, voucher codes, and closed-user groups are foundational to an affiliate programme. “These partners consistently deliver strong conversion rates and can drive incremental sales, especially when you give them something exclusive to work with,” Jessica tells us. They might not be the most glamorous part of your programme, but they deliver consistent performance.

But if you’re thinking about the bigger picture and focusing on brand awareness and customer loyalty, you need to be working with content publishers, influencers, and editorial platforms. As Marta puts it, “Content sites can be brilliant for showcasing what your brand is really about, but there has to be a proper fit with their audience. When it clicks you’re not just getting customers, you’re getting the right customers who stick around.”

And don’t sleep on Comparison Shopping Services (CSS), especially if you’ve got a decent-sized product catalogue. CSS partners can provide you with significant visibility through Google Shopping.retail affiliate marketing cover photo

Don’t Just Turn Up for Black Friday

Everyone gets excited about Q4 with Black Friday, Christmas and end-of-season sales. But showing up only when everyone else is shouting the loudest? That’s not a strategy.

“Not every brand can afford to slash prices by 50%,” says Jessica. “But you can still win during peak periods by focusing on value in other ways such as free shipping, gift with purchase, extended returns. It’s about making the customer feel like they’re getting something special.”

Marta also champions for building year-round relationships with your publishers, as well: “The publishers who support you when things get competitive are the ones you’ve been working with all year. We lock in quarterly deals with top publishers to help our clients secure exposure ahead of the rush.”

Something people often forget is that seasonality isn’t just about discounts. Got a new product launching? A back-to-school edit? There’s your seasonal moment right there. Think beyond the flash sale. If you’re interested in learning more about how to take advantage of seasonal events via affiliates you can download our free affiliate marketing calendar guide here.

Standing Out When Everyone’s Doing the Same Thing

The affiliate space is crowded with retailers, so how do you ensure your brand stands out from the crowd?

First off, your creativity needs to be fresh. “Refresh your banners and copy regularly to align them with what’s happening seasonally or trend-wise. It sounds basic, but it makes a real difference to engagement,” Jessica explains. Throw in some exclusive or limited-time offers, and you’re already ahead of most of the competition.

But Marta reckons you need to go deeper than that: “Start by really understanding your audience – who they are, what else they’re buying, which partners influence their decisions. That insight helps you put your money where it’s going to convert.”

The brands that stay relevant are the ones willing to try new partners, test different models, and not just stick with what they’ve always done.

Content and Influencer Partnerships That Work

power of performance influencer partnerships

When it comes to working with content creators and influencers, there’s a balance between giving them what they need and giving them space to do their thing.

“Make their lives easier by providing ready-to-go assets such as lifestyle shots, headline copy, CTAs, curated product selections. This is especially important in fast-moving categories like fashion and beauty, where trends change overnight,” says Jessica.

But brands need to be mindful of being too controlling with their briefs. As Marta highlights, “If it feels like a paid post, audiences will see right through it. The partnerships that work are where the creator genuinely believes in the brand and has the freedom to be creative with how they present it.”

One thing worth considering? Working with content creators outside your obvious niche. Sometimes the best relevance comes from understanding what else your customers care about.

The Stuff That Can Trip You Up

Affiliate marketing isn’t all sunshine and commission payments. Some real challenges can derail your programme if you’re not on top of them.

Quality control is something we manage strategically across all of our client programmes: “We’re manually auditing partner activity and working closely with networks to make sure programme terms are being followed. It’s important that we work with high-quality, incremental partners who add value to the programme instead of detracting from it.”

On the other hand, Marta’s seeing how rising costs and longer onboarding times are making life harder for brands: “The space is crowded, and publishers are being pickier about who they work with. Without a solid plan and the budget to back it up, it can be tough to get noticed.”

And then there’s the tech side. We’re working proactively with our clients to keep their tracking up to date and efficient. “It’s vital to ensure activity is tracked correctly, and we always ask brands to keep us in the loop about any changes to their site which could affect this. If your tracking breaks, you could be overpaying or missing crucial data,” Marta explains.

Sometimes the best thing you can do is simplify and focus on fewer, better-quality partners, rather than trying to manage hundreds of mediocre ones.

The Bottom Line

Affiliate marketing has massive potential for retail brands, but only if you approach it properly. From choosing the right partners to keeping your creative fresh and building genuine, long-term relationships, the brands that succeed are those that treat affiliate marketing as a core part of their marketing strategy, not just a nice-to-have.
