Reflecting on 2025: Marketing Lessons Learned at Sierra

As we step into 2026, we take time to pause, reflect, and reset for what’s next. 2025 brought new technologies and rapid change, and with that, valuable business and marketing lessons that continue to shape how we think, work, and deliver impact.

We asked some of our team members to share their 2025 learnings and advice as we start the year.

Here’s what they had to say:

Top Marketing Lessons from 2025

Marion DB - Sierra Marketing Founder and Strategy Director

For Marion, 2025 has been a year of validation and consolidation. 

1. Stick to the fundamentals 

With rapid advances in technology, the rise of AI, increasingly crowded markets, global uncertainty, and information moving faster than ever, it’s easy for marketing and communication agencies to become distracted, chase trends, and overcomplicate their strategies.

This year, Marion found that returning to the basics was the most effective approach to achieving success. This meant focusing on understanding customer needs, developing clear value propositions, selecting the most effective communication channels, delivering consistent messaging, solving real problems, and creating positive, market-fit experiences through products and services.

2. Niche marketing continues to outperform broad strategies 

A targeted approach with advanced market segmentation offers greater relevance by addressing specific needs and avoiding the dilution of efforts across markets. While this isn’t new, in fast-moving environments, focus makes a world of difference.

This year, Marion found that consistent, clear, and tailored messages that resonate with a narrow audience achieve far more than generic campaigns (particularly in B2B). This approach helps position brands as authorities and builds trust and credibility much faster. Sierra experienced this first-hand. Following several successes within specific sectors such as architecture and planning and management consulting, dedicated go-to-market programs were developed to support these segments, focusing on clear positioning, relevance, and repeatable systems, and the results have been remarkable.

3. AI integration is fundamentally human

Over the past few years, the team has been using AI to boost productivity, explore new possibilities, accelerate and deepen secondary market research, support content production, and build automations. Through all of this, one constant remained clear: the quality of the output is only as good as the input (and that input is us, humans).

In 2025, both the successes and the small setbacks experienced with AI were human-led. It wasn’t so much a groundbreaking lesson as it was an important realisation. AI proved to be a powerful tool, but human judgment, creativity, and intent ultimately shaped meaningful outcomes.

Manon - Sierra Marketing Operations Manager

1. AI search has fundamentally changed brand discovery 

In 2025, it became clear that traditional SEO alone is no longer sufficient. Visibility now depends on how well a brand is understood and interpreted by AI systems. As a result, concepts like AEO and GEO have become central, shifting the focus from keyword rankings to structured, AI-readable online brand presence.

2. Marketing systems consistently outperform isolated tactics

Businesses that “do marketing when they have time” struggle to grow, while those operating with clear strategies, systems, and processes achieve more predictable and measurable results. Sustainable growth depends on strategy, structure, and consistency.

3. Visibility is driven by relevance, proof, and experience (not volume)

Authority is no longer built through content volume alone. Instead, it comes from aligned messaging, consistent execution, and strong social proof across an entire ecosystem (including social media, website, emails, Google Business Profiles, …). Brands that invest in experience grow faster and more sustainably.

Edelle - Sierra Marketing Marketing Coordinator

1. On a professional approach: Consistency

Whether someone is just starting or has been with a company for some time, showing up every day, staying organised, and doing the work (even on busy or overwhelming days) makes a meaningful difference over time. Consistency helped Edelle learn faster, build better habits, and feel more confident in her role. Small, steady efforts really do add up.

2. On a personal approach: Compassion 

On a personal level, Edelle learned compassion, especially towards herself. As a mum of two young men and a fur mum to five dogs, life can get loud and chaotic very quickly. This year reinforced that doing everything perfectly isn’t required to do a good job. Learning to pause, be kinder to herself, and take things one day at a time made a huge difference.

3. On a social approach: Patience

Whether getting to know new people at work, communicating with different personalities, or balancing relationships alongside everyday responsibilities, building meaningful connections takes time. Listening, adapting, and staying patient led to stronger relationships both professionally and personally.

Maria - Sierra Marketing Senior Communications Designer

1. Small ideas can drive meaningful impact when grounded in client understanding. 

In 2025, Maria observed that even simple creative ideas can deliver significant results when they are rooted in a deep and genuine understanding of client needs. Taking the time to listen, ask the right questions, and align creative decisions with real business challenges consistently led to stronger, more effective outcomes.

2. Embracing new technologies improves efficiency and creative execution.

Adopting new tools and technologies throughout the year helped streamline workflows, improve productivity, and create space for higher-value creative thinking. When used thoughtfully, these technologies supported better execution without compromising quality or strategic intent.

3. Flexibility is essential in a constantly changing environment.

With shifting priorities, evolving client needs, and ongoing market changes, flexibility proved to be a critical skill. Being able to adapt quickly, reassess plans, and respond with agility allowed creative projects on track and enabled continued delivery of value despite uncertainty.

Slava - Sierra Marketing Data Manager

1. A deeper understanding of property and strata law strengthened strategic decision-making. 

In 2025, Slava significantly expanded his knowledge of property and strata law, enabling him to better the regulatory and operational contexts in which clients operate. This deeper expertise supported more informed, compliant, and strategically sound solutions.

2. Using AI to create software solutions unlocked new capabilities. 

Throughout the year, Slava learned how to leverage AI in the development of software solutions, opening up new opportunities to automate processes, improve efficiency, and build more scalable, data-driven tools. This hands-on experience highlighted the practical value of AI when applied with clear intent and technical understanding.

3. Strategic thinking became clearer and more actionable.

Perhaps most importantly, 2025 brought greater clarity around what it truly means to work strategically. Moving beyond task execution, Slava developed a stronger focus on long-term thinking, prioritisation, and aligning solutions with broader business objectives — ensuring that efforts consistently delivered meaningful impact.

How These Help Shape Sierra

Collectively, these learnings helped shape how we operate, deliver value, and support clients more strategically. Insights into AI search and discovery strengthened our digital foundations, with clearer messaging, stronger entity structures, and content designed for both human audiences and AI systems across key platforms. The continued focus on structured marketing ecosystems reinforced our commitment to moving clients beyond ad-hoc activity toward clear strategies, defined processes, and measurable outcomes.

At the same time, a stronger emphasis on brand experience expanded our approach beyond individual deliverables to include customer journeys, website structure, messaging consistency, and multi-channel presence. Internally, these learnings fostered greater consistency, adaptability, and collaboration across roles (from coordination and creative execution to data-driven solution development), ensuring the team remained aligned, responsive, and focused on delivering meaningful, strategic results for clients.

Looking Ahead to 2026

While each of our journeys was unique, clear themes emerged: clarity, focus, adaptability, and human insight remain essential to effective marketing. In a fast-changing, noisy landscape, the fundamentals matter more than ever.

As 2026 kicks off, these lessons continue to guide a focus on strong foundations, clear positioning, thoughtful strategy, smart systems, and consistent execution, rather than chasing trends. With the right balance of human insight and technology, businesses can move from reacting to change to leading with purpose.

Looking ahead, focus, structure, clarity, trust, and adaptability will differentiate strong brands. Together, these principles set the foundation for meaningful, sustainable marketing in 2026.
