Looking for an agency?

Finding the right agency partner is one of the most critical decisions you can make for your business. The right partnership can accelerate change and turn your vision into reality, while the wrong one can lead to frustration and missed opportunities. A great agency is more than just a vendor; they become an extension of your team, bringing an outside-in perspective that challenges assumptions and drives real progress.

This guide provides a structured, step-by-step approach to help you find, validate, and engage the perfect agency for your specific needs.

Step 1: Define Your Problem, Not the Solution

Before you even start looking, the most important step is to clearly define the problem you are trying to solve. Many projects fail because they jump straight to a solution ("we need a new app") without first understanding the core business challenge.


  • Good Problem Definition: "Our member retention is declining because our digital services feel fragmented and don't provide consistent value across touchpoints."

  • Poor Problem Definition: "We need a new website and a new app."

A clear problem statement will help you find a partner who can provide a strategic solution, not just a technical execution.

Step 2: Identify the Right Type and Size of Agency

Finding the right partner begins with understanding the agency landscape. Your specific challenge will determine not only the type of expertise you need but also the size and structure of the team you'll be collaborating with.

Agency Types: Matching Expertise to Your Problem

It's crucial to distinguish between different agency specializations to ensure their core services align with your business goals.


  • Digital Marketing Agency: Their primary focus is on audience acquisition, engagement, and conversion. They are experts in channels like SEO, PPC, social media, content marketing, and email campaigns.

    Choose them when: Your main challenge is to reach and convert more customers through specific digital channels. You have a product or service ready for the market and need to amplify its visibility and drive sales.

  • Design Agency: Their core competency is craft and aesthetic execution. They excel at creating beautiful and functional brand identities, websites, apps, and other visual materials based on a relatively clear set of instructions.

    Choose them when: You have a well-defined strategy and need a partner to deliver high-quality, polished design work. Their role is to bring your vision to life with craftsmanship and attention to detail.

  • Strategic Design Agency: Their purpose is to

solve complex business problems and accelerate change. They operate in the cross-section between business, technology, and user needs, using a journey-led approach to turn vision into action. A strategic partner like DAY21 doesn't just design or strategize—they help you implement the solution and build the capabilities to sustain change.

  • Choose them when: Your challenge is complex, your digital experiences are fragmented, or you need to drive a significant transformation. They are not just given a solution to execute; they are your partners in defining the problem, shaping the strategy, and delivering the outcome.

Agency Size: Finding the Right Fit

The size of an agency is a critical factor that affects everything from team structure and competencies to speed and collaboration.


  • Large Agencies: A large agency can be the right choice when you need to staff large, long-term projects that require a wide range of competencies. They can provide big teams with various levels of experience and have the bandwidth to manage extensive, multi-year engagements.

  • Smaller, Specialized Agencies: With a smaller agency, you often gain a more dedicated and consistent team. The key people you meet at the beginning are typically the ones who will see the project through to completion. This continuity ensures that knowledge and context stay within the team, which often results in higher speed and a deeper understanding of your company's unique challenges and culture. This model is built on a foundation of

true partnership and deep collaboration, where the agency embeds itself in your team to make change happen together.

Step 3: Create Your Shortlist

Once you know the type of agency you need, you can begin building a shortlist. Look for evidence that they can deliver the quality and strategic thinking you require.


  • Review Their Case Studies: Look past the glossy images. Do their cases describe challenges similar to yours? Do they articulate a clear, insight-driven process and demonstrate measurable business impact?Look for partners who focus on turning vision into action.

  • Assess Their Work: Examine the quality of their design and strategic thinking. Great experience design is more than just aesthetics; it should be intuitive, delightful, and solve real user needs.

  • Seek Recommendations: Talk to your network. A recommendation from a trusted peer is often the strongest signal of an agency's capabilities and collaborative spirit.

Step 4: Validate Your Choice

With a shortlist of 2-3 agencies, the next step is to validate your choice by digging deeper into their approach and culture. The goal is to find a team you can truly collaborate with.


  • Look for a Cultural Fit: A true partnership requires deep collaboration. Look for an agency that works as an integrated part of your team, not in parallel. Their principles should align with yours. DAY21, for instance, operates on being

high quality, insight-driven, and flexible, adapting our approach to your specific needs.

  • Understand Their Process: A great agency should have a clear, structured approach. Do they have a proven methodology, like the classic Double Diamond (Understand, Direction, Concept, Build), that ensures they solve the right problem?.

  • Read Their Content: An agency's articles and guides reveal how they think. Do they bring an "outside-in" perspective that can help you see your business through the eyes of your customers?

Step 5: Make Contact with a Great Brief

You are now ready to reach out. The best way to start a productive conversation is with a well-crafted brief. A strong brief provides the context, clarity, and goals needed for an agency to understand your challenge and propose a valuable solution. It should focus on the "why" (the problem) and the "what" (the objectives), leaving room for the agency to help you define the "how."


A great brief is the foundation of a great partnership.
