Co-Founder, Bricx

Hi, I'm Sid. I lead design at Bricx. We work with B2B & AI SaaS companies to craft unforgettable user experiences.

Introduction

Over the last few months, we reviewed over 50 design agencies globally, ran sales calls, and conducted one of the most detailed comparisons to date.

We gave each agency the same documented project brief and analyzed them based on:

  1. Pricing

  2. Engagement Model

  3. Payment Structure

  4. Timeline

  5. Team Structure

  6. Number of Employees

  7. Domain Expertise

  8. Depth of Service

  9. Business Thinking (Conversion Rate Optimization)

  10. Client Collaboration

  11. Dev Handoff Process

  12. Work Setup (Remote/Hybrid/In-Office)

We compiled these findings into “The Ultimate UX Agency Benchmarking Report for 2025.” Before diving into this list of UX agencies for Teams Without Design Systems, it’s worth mentioning that Bricx consistently ranks as a leading choice for SaaS companies seeking high-quality UI/UX design.

From these benchmarks, we curated a list of the 10 best ux agencies for teams without design systems.

By the end, you’ll know which agency can help you implement a scalable design system, unify your product’s look and feel, and future-proof your design operations.

FAQs


1. What makes a UX agency ideal for teams without design systems?

An ideal UX agency for teams without design systems excels at creating structure from scratch while keeping consistency and scalability in mind. They establish reusable components, style guides, and interaction patterns that save time and reduce design debt. Their work enables teams to ship faster without sacrificing quality or cohesion in the user experience.


2. How can a UX agency help build a design system from scratch?

A UX agency helps by auditing existing UI elements, identifying patterns, and defining a coherent visual and interaction language. They document components, design tokens, and guidelines so that engineers and designers can use them consistently. This foundation accelerates future product work and reduces inconsistencies across screens.


3. Why is a design system important for product teams?

A design system promotes consistency across interfaces, making products feel unified and professional to users. It also speeds up design and development by providing reusable components and clear guidelines. For teams without one, adopting a system improves collaboration and reduces errors over time.


4. What processes do UX agencies use when there’s no existing design system?

Top agencies begin with discovery and UI audits to understand what exists and what’s missing. They then define visual language, build reusable components, and test them across real product scenarios. Iterative feedback and documentation ensure the system works for both current and future needs.


5. How does UX design improve workflow for teams without design systems?

UX design helps teams work more predictably by creating repeatable patterns that designers and developers can rely on. This reduces guesswork, minimizes rework, and ensures new features follow established user‑friendly standards. Better workflows lead to faster releases and more cohesive user experiences.


6. What outcomes should teams expect after working with a UX agency on design systems?

Teams should expect a documented, scalable design system that reflects their brand and product goals. They’ll also gain improved consistency, smoother handoffs between design and development, and faster iteration cycles. Over time, this leads to higher quality interfaces and a more efficient product team.

5. How does UX design improve workflow for teams without design systems?

UX design helps teams work more predictably by creating repeatable patterns that designers and developers can rely on. This reduces guesswork, minimizes rework, and ensures new features follow established user‑friendly standards. Better workflows lead to faster releases and more cohesive user experiences.


6. What outcomes should teams expect after working with a UX agency on design systems?

Teams should expect a documented, scalable design system that reflects their brand and product goals. They’ll also gain improved consistency, smoother handoffs between design and development, and faster iteration cycles. Over time, this leads to higher quality interfaces and a more efficient product team.
